An efficient protocol has been developed for direct shoot organogenesis from embryo axes derived from mature seeds of two different landraces of Bambara groundnut. Multiple shoots were initiated on several media containing different concentrations and combinations of benzylaminopurine (BAP) or thidiazuron (TDZ). Efficient regeneration occurred when the embryo axes were first plated for 6 days on a medium containing high concentrations of BAP (1 mg/l) and alpha-naphthaleneacetic acid (NAA, 1 mg/l) and then cut transversely and transferred onto a medium containing 1.5 mg/l BAP. Shoot regeneration frequency was 100% and from five to eight shoots per explant were obtained. The importance of using embryo explants and cytokinins in the culture media, with respect to controlling the development of a highly organogenic system, was demonstrated. Histological studies revealed that proliferating buds originated directly from the superficial layers of the explants without an intermediate callus phase. The regenerated shoots were rooted on a medium containing 1 mg/l NAA and then transferred to the greenhouse. Flow cytometric analyses and chloroplast counts of guard cells suggested that the regenerants were diploid. All were morphologically normal and fertile. The short duration, high efficiency and low frequency of somaclonal variation of this system make it well suited for wider biotechnological applications of Bambara groundnut-a neglected and under-utilized crop. 相似文献

This study was designed to evaluate the effect of phytohormones on plant regeneration from epicotyl and hypocotyl explants
of two groundnut (Arachis hypogaea) cultivars. Explants cultured on media with auxins and in combination with cytokinin produced high frequency of callus. After
four weeks, callus from these cultures was transferred to medium with cytokinin and reduced auxin, shoot buds regenerated
from the cultures. A high rate of shoot bud regeneration was observed on medium supplemented with 2.0 mg/L BAP and 0.5 mg/L
NAA. Among the different auxins tested, NAA was found to be most effective, producing the highest frequency of shoot buds
per responding cultures. Of the two explants tested, epicotyl was found to be best for high frequency shoot bud regeneration.
Multiple shoots arose on MS medium supplemented with BAP or kinetin (1.0–5.0 mg/L) plus IBA (1.0 mg/L), with maximum production
occurring at 5.0 mg/L. The elongated shoots developed rootsin vitro upon transfer to MS medium supplemented with NAA or IBA (0.5–2.0 mg/L) and kinetin (0.5 mg/L) for 15 days.In vitro produced plantlets, were transferred to soil and placed in a glasshouse developed successfully, matured, and set seeds. 相似文献

Calli from hypocotyl explant of Cuminum cyminum L. (Cumin) grew rapidly on Gamborg's B5 basal medium with the following supplements, (i) 0.5 mg/l — 2,4-D (ii) 4 mg/l — NAA plus 2 mg/l — Kinetin and (iii) 0.2 mg/l — NAA plus 0.2 mg/l — BAP, whereas calli from leaf explant in these media grew slowly. Hypocotyl and leaf calli produced roots when transferred to basal medium only and shoots in basal medium with 0.5 mg/l NAA and 0.1 mg/l BAP. Ninety percent of the shoots produced roots when they were transferred to half strength MS inorganic salts supplemented with 0.5 mg/l each of IBA and NAA.Fifty to sixty percent of rootless as well as rooted shoots produced terminal umbellate flowers on this medium. 相似文献

Summary The response of groundnut cotyledons to the presence of various growth regulators in concentrations from 0.1 to 5 mg/l has been studied in detail using several genotypes of groundnut on two different media. Cotyledons with embryo axis, cultured on Blaydes' medium with cytokinins, produced shoots, in the axils of which 2–7 flower buds could be seen. The frequency of flower bud induction in general increased with increasing concentrations of cytokinins, the optimal levels being 3 mg/l of KN or 4 mg/l of BAP. Cotyledons without embryo axis, cultured on Blaydes' medium with BAP (0.5 mg/l), produced a cluster of flower buds directly, ranging in number from 8–28, without any vegetative growth. Excised embryo axes cultured on the same medium gave plantlets without flower buds. The growth regulators IAA, NAA, GA3 and ABA failed to induce flower buds in independent treatments. However, lower concentrations of IAA and NAA in combination with cytokinins exerted a positive influence on flowering. The blooming of the flower buds was facilitated on media supplemented with low concentrations of cytokinins. Six percent of the induced flowers resulted in gynophore development and ultimately formed pods when cultured under complete dark conditions in modified MS medium supplemented with kinetin. 相似文献

This report deals with micropropagation of the critically endangered and endemic Turkish shrub, Thermopsis turcica using callus, root and cotyledonary explants. Callus cultures were initiated from root and cotyledon explants on MS medium
supplemented with 0.5–20 μM NAA or 2,4-D. The root explants were found to be better in terms of quick responding and callusing
percentages as compared to the cotyledons. Organogenic callus production with adventitious roots and shoots were obtained
on MS medium with only NAA. The calli obtained with NAA, root and cotyledonary explants were cultured with BA and kinetin
(2–8 μM) alone or in combination with a low level (0.5 μM) of 2,4-D or NAA. The best regeneration of shoots from root explants
was observed on hormone-free MS medium. NAA with BA or kinetin in the medium improved shoot induction from the calli obtained
with NAA. Maximum percentage of shoots (93.3%), maximum number of shoots (6.2) and maximun length of shoots (8.22 cm) were
achieved from cotyledonary explants at 4 μM BA and 0.5 μM NAA. The presence of 0.5 μM or higher levels of 2,4-D in shoot induction
medium inhibited the regeneration in T. turcica explants. 83% of in vitro rooting was attained on pulsed-IBA treated shoots. The regenerated plants with well developed shoots and roots were successfully
acclimatized. Application of this study’s results has the potential to conserve T. turcica from extinction. 相似文献

The shoot apices of ten groundnut interspecific hybrids, showing peanut stripe virus symptoms were used as explants. Murashige
and Skoog (MS) medium containing 1 mg dm-3 each of naphthaleneacetic acid (NAA) and benzylaminopurine (BAP) supported maximum callusing of the hybrids J 11 × Arachis sp. PI 30008 as well as J 11 × A. sp. Manfredi # 5 (86.3 and 82.6 %, respectively). On MS medium with 3.5 mg dm-3 NAA and 0.2 mg dm-3 BAP, the meristems of J 11 × A. stenosperma as well as J 11 × A. otavioi gave good response (79.7 and 77.2 %). The regeneration frequencies ranged from 16.7 to 76.9 % and was more than 30 % in all hybrids
except for J 11 × PI 30085. Shoots (5 cm) regenerated from the virus-free (ELISA tested) calli rooted well (60 – 80 %) on
MS basal medium supplemented with 0.4 % activated charcoal and 200 mg dm-3 casein hydrolysate. In addition, long shoots which failed to produce roots, when transferred to soil during rainy season
and protected from direct sun got established.

The effect of various hormonal combinations on regeneration of shoots and roots from meristem-derived callus of Crocus sativus L. and activities of antioxidant enzymes have been studied. The most efficient regeneration occurred with 1.0 mg dm−3 1-naphthaleneacetic acid (NAA) + 1.0 mg dm−3 thidiazuron and 1.0 mg dm−3 NAA + 2.0 mg dm−3 kinetin. For sprouting, regenerated shoot were subcultured on Murashige and Skoog medium containing 1.0 mg dm−3 NAA + 1.0 mg dm−3 benzylaminopurine (BAP). Protein content and superoxide dismutase activity decreased in regenerated shoots and roots and
increased in sprouting shoots, while catalase (CAT), peroxidase (POX) and polyphenol oxidase (PPO) activities increased during
organogenesis and decreased in sprouting shoots. High CAT and PPO activities were detected in regenerated roots, whereas high
POX activity was observed in regenerated shoot. 相似文献

A rapid and efficient regeneration procedure via direct organogenesis from mature embryo axes of ten landraces of bambara
groundnut has been developed. Embryo axis cultured on hormone-free Murashige and Skoog (MS; Murashige and Skoog, Physiol Plant
15:473–497, 1962) medium produced only single plants, while multiple shoots were produced at the nodal and apical regions of explants within
3–4 wk of culture on MS medium plus B5vitamins (Gamborg et al., Exp Cell Res 50:151–158, 1968) and supplemented with cytokinins such as 6-benzylaminopurine (BAP), kinetin, zeatin, and thidiazuron alone or in combination
with α-naphthaleneacetic acid. BAP proved to be the most effective cytokinin tested in this study. The shoot-forming ability
of embryo axis was influenced by BAP concentration, and optimal BAP concentration was determined. Vertical orientation of
explants on the medium was significantly better than the horizontal position for shoot induction. Genotypes also showed significant
differences in their regeneration in terms of percent response (28.77 ± 3.83–77.70 ± 10.64%) as well as an average number
of shoots per explant (5.44–12.63). Regenerated shoots elongated in the same medium and rooted upon transfer to full-strength
MS medium devoid of growth regulators. Regenerated plants were successfully transferred to soil and all surviving plants were
morphologically normal. 相似文献

This study describes in vitro shoot induction and plant regeneration from a mature apical meristem and nodal explants of the endangered medicinal shrub
Vitex agnus-castus. Multiple shoots were induced directly from the axis of nodal and apical meristem explants on Murashige and Skoog (MS) medium
containing 3% sucrose and different concentrations (1.0, 1.5, 2.0, and 2.5 mg/l) of 6-benzyl aminopurine (BAP) in combination
with Kinetin (Kin) and α-naphthalene acetic acid (NAA), both at 0.1 mg/l. BAP and Kinetin were used as supplements to MS basal
medium, either individually or in combination with auxins. The optimal concentration of BAP for inducing bud break was found
to be 2.0 mg/l when Kinetin was at 0.1 mg/l. Regeneration frequency was highest for both apical meristem and nodal explants
(94.5% and 90.3%, respectively) when explants were cultured on MS medium supplemented with BAP (2.0 mg/l) and Kin (0.1 mg/l).
A maximum of 7.7 ± 0.4 and 6.7 ± 0.2 shoots were obtained per explant for apical meristem and nodal explants, respectively.
Regenerated shoots, transferred to MS medium supplemented with either 1.0 or 1.5 mg/l BAP combined with 0.1 mg/l GA3, showed maximum elongation of 6.7 ± 0.4 and 6.0 ± 1.3 cm in apical meristem and nodal explants, respectively. In vitro regenerated shoots transferred to half-strength MS medium supplemented with 0.1 mg/l IBA induced 90.4% of the shoots to form
roots after 30–35 d of culture. Up to 80% of the regenerated shoots were successfully established in soil in the greenhouse. 相似文献

Androgenic haploids of the neem tree (Azadirachta indica A. Juss.) were produced by anther culture at the early- to late-uninucleate stage of pollen. Haploid formation occurred via callusing. The best medium for inducing callusing in the anther cultures was Murashige and Skoog's basal medium (MS) (9% sucrose) supplemented with 1 microM 2,4-D, 1 microM NAA and 5 microM BAP, while anther callus multiplied best on MS medium supplemented with 1 microM 2,4-D and 10 microM Kn. These calli differentiated shoots when transferred to a medium containing BAP; 5 microM BAP was optimum for young calli (75% cultures differentiated shoots), but older calli showed the best regeneration with 7.5 microM BAP. Shoots elongated at a lower concentration of BAP-0.5 microM. These shoots were multiplied by forced axillary branching and rooted in vitro. The plants were subsequently established in soil. Of the plants that regenerated from anther callus 60% were haploid, 20% were diploid and 20% were aneuploid. 相似文献

Anthurium anther culture was successfully established using half-anthers as explants. Explants were cultured on Winarto–Teixeira basal
medium (WT-1) containing 0.01 mg/l α-naphthalene acetic acid (NAA), 0.5 mg/l thidiazuron (TDZ), and 1.0 mg/l 6-benzylaminopurine
(BAP), or on New Winarto–Teixeira basal medium (NWT-3) supplemented with 0.02 mg/l NAA, 1.5 mg/l TDZ, and 0.75 mg/l BAP for
callus initiation. Regenerated calli produced multiple shoots on WT-1, which were then rooted in NWT-3 supplemented with 1%
activated charcoal. Plantlets were acclimatized ex vitro using a mixture of burned rice husk, rice husk, and bamboo peat (1:1:1,
v/v/v) as the potting medium. There was considerable morphological and cytological diversity of regenerants derived from anther
culture, which are described in detail in this study. The callus cluster color ranged from green to light green and had a
high regeneration capacity (7.3 and 4.8 shoots/callus cluster), light reddish-yellow callus showed moderate regeneration (2.6
shoots/callus cluster), while reddish-yellow callus had the lowest regeneration capacity (1.5 shoots/callus cluster). Morphological
variations clearly observed in regenerants derived from this technique included alterations in plant size, peduncle length,
spathe position compared to leaves, the type and number of buds, spathe and spadix color, and spadix length. There were also
cytological variations in both in vitro and ex vitro regenerants of anther culture with 23–29% haploids, 5–10% aneuploids,
56–69% diploids, and 3–4% triploids. The results strengthen other studies in which the development of anther cultures, especially
via callus formation, resulted in morphological and cytological alterations. These variations have been discussed to great
length in this paper. 相似文献

A simple and rapid method for multiple shoot formation in vitro from immature embryo axis explants of Carica papaya L. cvs. Honey Dew, Washington and Co2 is described. Multiple shoot regeneration was achieved by culture of the explants on
modified Murashige and Skoog (MS) medium supplemented either with thidiazuron (TDZ; 0.45–22.7 μM) or a combination of benzylaminopurine
(BAP; 0.2 – 8.84 μM) and naphthalene acetic acid (NAA; 0.5 – 2.64 μM). Highest frequency of shoot regeneration occurred on
medium supplemented either with 2.25 μM TDZ or a combination of BAP (4.4 μM) and NAA (0.5 μM). Composition of the basal media
influenced the frequency of multiple shoot initiation. Stunted shoots regenerated at 4.5 μM and higher concentrations of TDZ.
Such shoots could, however, be elongated by transfer to medium containing 5.7 μM GA3. Rooting of the regenerated shoots was achieved in presence of indolebutyric acid (IBA; 4.92 – 19.68 μM), however, least
response was in presence of 14.7 μM IBA. Rooted plants were hardened and transferred to pots.

Efficient plant regeneration was achieved from callus derived from immature-cotyledon explants of oleaster (Elaeagnus angustifolia L.). Calli were obtained on MS media containing 3% sucrose and different concentrations of TDZ. The highest rate of green,
compact and nodular callus was formed on MS medium supplemented with 1 mg/l of TDZ. Shoot organogenesis was achieved when
the callus was transferred onto MS media containing 3% sucrose and BA alone (05–4 mg/l) or BA (0.5 and 1 mg/l) combined with
NAA or IAA (0.5 and 1 mg/l). Maximum organogenesis was obtained with 1 mg/l BA in combination with 0.5 mg/l NAA. Rooting of
the shoots was achieved on MS medium supplemented with 0.2 mg/l IBA. Regenerated plantlets were acclimatized and successfully
transplanted to soil. 相似文献

A rapid, simple and efficient protocol for direct in vitro multiple shoot induction and plantlet recovery was achieved from shoot tip explants of Bambara groundnut [Vigna subterranea (L.) Verdc.]. Shoot tips, were isolated from in vitro-grown seedlings and cultured on Murashige and Skoog basal medium (MS) containing Gamborg’ vitamins (B5) and supplemented with different concentrations of the plant growth regulators Thidiazuron (TDZ), N6-benzylaminopurine (BAP), Kinetin (KIN) and Adenine sulfate (ADS). TDZ 0.45 μM was found to be best for shoot multiplication with a mean of 11shoots per explant. Among the carbon sources tested, the best response in terms of mean number of shoots per explant was obtained with sucrose (11). The mean number of shoots per explant induced among the studied landraces of Bambara groundnut varied from 9 to 13. Individual shoots, aseptically excised, produced normal roots within 2 weeks on the basal MS medium supplemented with Indole Butyric Acid (IBA) or Naphthalene acetic acid (NAA). The highest number of roots per shoot and the longest roots were obtained on MS medium with 2 mg/L IBA. Rooted plantlets were successfully hardened under greenhouse conditions and subsequently established in the field conditions, with a recorded survival rate of 70 and 80?%, respectively. The transferred plants in the field were morphologically normal and fertile. This protocol can be efficiently used for mass propagation, germplasm preservation and probably also for gene transfer of Vigna subterranea (L.). 相似文献

The embryogenic calli (EC) were obtained from hypocotyl explants of groundnut (Arachis hypogaea L.) cultured on Murashige and Skoog (MS) medium supplemented with different concentrations of 2,4-dichlorophenoxyacetic acid
(2,4-D) in combination with 0.5 mg dm−3 6-benzylaminopurine (BAP). The EC were exposed to γ-radiation (10–50 Gy) or treated with 1–5 mM of ethyl methane sulphonate
(EMS) or sodium azide (SA). The mutated EC were subcultured on embryo induction medium containing 20 mg dm−3 2,4-D. Somatic embryos (SE) developed from these calli were transferred to MS medium supplemented with BAP (2.0 mg dm−3) and 0.5 mg dm−3 2,4-D for maturation. The well-developed embryos were cultured on germination medium consisting of MS salts with 2.0 mg dm−3 BAP and 0.25 mg dm−3 naphthaleneacetic acid (NAA). Well-developed plantlets were transferred for hardening and hardened plants produced normal
flowers and set viable seeds. The fresh mass of the EC, mean number of SE per explant and regeneration percentage were higher
at lower concentrations of mutagens (up to 30 Gy/3 mM). Some abnormalities in regenerated plants were observed, especially
variations in leaf shape. 相似文献

The endosperms of Carthamus tinctorius cv. HUS-305, excised at globular to heart-shaped stages of zygotic embryo development, were cultured on Murashige and Skoog’s
medium (MS) supplemented with different concentrations of 6-benzylaminopurine (BAP), kinetin, thidiazuron (TDZ), 2,4-dichlorophenoxyacetic
acid (2,4-D) or α-naphthalene-acetic acid (NAA). The highest incidence of callusing was on 2,4-D supplemented media. However,
embryos differentiated only from the calli developed on media supplemented with BAP, kinetin or TDZ with the last eliciting
maximum embryogenic response. The addition of a reduced nitrogen source, casein hydrolysate to MS medium supplemented with
BAP and/or NAA, did not stimulate the response. However, adenine sulphate (100 mg dm−3) promoted the induction of somatic embryos. Upon transfer to MS basal medium or the same supplemented with 0.61 μM gibberellic
acid (GA3), plumular poles of few embryos elongated resulting in the development of shoots. 相似文献

Leaf explants of Solanum khasianum regenerated on MS medium containing 2, 4-D (3 mg/l) and kinetin (1 mg/l). Shoots could be induced from these calli on medium containing BAP (3 mg/l) alone. Rhizogenesis of these shoots occurred when transferred to medium containing 2 mg/l NAA. The yield of solasodine — a pharmaceutically important compound, from 4-month-old callus tissue was remarkable at 2 per cent of dry weight. 相似文献

Callus tissue was induced from floral parts of African violetcultured on MS medium containing NAA (2 mg I1) and BAP(0.2 mg I1). When maintained on this medium in the presenceof light, the callus produced many shoots and roots. Large numbersof adventitious shoot buds were formed apparently in the absenceof callusing when ovary, sepal, and petal tissue was culturedon MS medium supplemented with BAP (1 mg I1) and NAA(1 mg I1). In contrast, culturing the same floral partson MS medium augmented with kinetin (1 mg I1) and NAA(0.5 mg I1) and NAA (0.5 mg 1-1) led to the profuse developmentof roots. Organs seemed to be initiated from the epidermis ofcultured floral parts and did not appear to be related to particularcells or loci. Transfer of shoots to MS medium deviod of growthsubstances resulted in the formation of plantlets, which ata height of 3 cm could be transferred to soil and grown to maturitywithout variation in morophology or cytology. 相似文献

Pretreatment in thidiazuron improves the in vitro shoot induction from leaves in Curculigo orchioides Gaertn., an endangered medicinal plant 总被引:1,自引:0,他引:1

Leaf regeneration via direct induction of adventitious shoots obtained from an endangered medicinal plant, Curculigo orchioides Gaertn. by pretreating with thidiazuron. C. orchioides is an endangered medicinal herb belonging to the family Hypoxidaceae. Direct inoculation of leaf pieces on MS medium supplemented
with various concentrations of BAP (2–8 μM) or TDZ (2–8 μM) alone or in combination with NAA (0.5 and 1.0 μM) produced low
shoot induction both in terms of % response and number of shoots per explant. Hence, leaf explants were pretreated with 15,
25 or 50 μM thidiazuron (TDZ), for 6, 24 or 48 h with the aim of improving shoot regeneration from cultured explants. After
pretreatment, explants were transferred to an agar solidified MS medium that was supplemented with BAP (4 μM), TDZ (6 μM),
BAP (4 μM) + NAA (1.0 μM), TDZ (6 μM) + NAA (0.5 μM). Control explants were incubated directly on the medium without any pretreatment.
The pretreatment of explants with 15 μM TDZ for 24 h significantly promoted the formation of adventitious shoots and the maximum
response was observed on MS medium supplemented with 6 μM TDZ. In this medium, 96 % cultures responded with an average number
of 16.2 adventitious shoots per explant. The percentage of leaf explants producing shoots and the average number of shoots
per explant were significantly improved when TDZ pretreated leaves were cultured onto MS medium supplemented with BAP or TDZ
alone or in combination with NAA. The rooted plantlets were successfully transplanted to soil with 90% success. The present
investigation indicated the stimulatory role of TDZ pretreatment in regulating shoot regeneration from leaf explants of C. orchioides. 相似文献

A protocol to obtain regenerated plants from protoplasts of Solanum torvum Sw a wild species of eggplant resistant to Verticillium wilt is reported. Leaf protoplasts were enzymatically isolated from six-week old seedlings grown in a controlled environment chamber. Protoplasts were plated on modified KM medium (0.4 M glucose)+(mg/l): 1.0 p-chlorophenoxyacetic acid (CPA)+1.0 naphthaleneacetic acid (NAA)+0.5 6-benzylaminopurine (BAP) and 0.02 abscisic acid (ABA). The protoplast density was 5×104 per ml with 5 ml placed in each of two quadrants in X-dishes (100×15 mm). The reservoir medium was modified KM+(mg/l): 0.1 NAA+0.5 BAP+0.1 M sucrose+0.1 M mannitol+0.6% washed agar+1% activated charcoal. Dishes were initially placed in the dark at 27°C. Protoplast division was initiated in 1–2 weeks and 4 weeks later p-calli were 1–3 mm. Plating efficiency was 11% when measured at 3 weeks. Six-week old p-calli were transferred individually onto Whatman No. 1 filter paper layered on modified KM (0.15 M sucrose)+mg/l: 2.0 indoleacetic acid (IAA)+2.0 zeatin+0.5% washed agar for 2 weeks. Subsequently, shoots occurred within 4 weeks at 70% efficiency on MS+30 g/l sucrose+2 mg/l zeatin. Shoots were rooted on half strength MS+10 g/l sucrose.Abbreviations ABA
