Fast growing calli induced from hypocotyl segments ofGentiana crassicaulis were used for preparation of protoplasts. High yields of viable protoplasts were produced in an enzyme solution containing 1–2% cellulase, I% pecfinase, and 0.5% Hemicellulase. Protoplasts were cultured in KM8P medium containing 1 mg/l 2,4-D, 0.5 mg/l 6BA, 500 mg/l LH, 0.5 M glucose and 0.1 M mannitol by the solid-liquid dual layer culture method. First division occurred within 4–5 days of culture at a frequency of 17.8%. Sustained divisions led to callus formation. Periodically diluting the cultures with freshly prepared liquid medium containing 1% glucose was critical for colony formation. Protocolonies about 2 mm in size were transferred onto MS medium supplemented with 3 mg/l ZT, 2 mg/l 6BA, 1 mg/l GA3, 1 mg/l NAA and 6% sucrose to obtain embryogenic calli. Plantlets were regenerated via somatic embryogenesis at high frequency on hormone-free MS Medium.Abbreviations 6BA

Leaf explants of Paphiopedilum phiIippinense hybrids (hybrid PH59 and PH60) directly formed adventitious shoots from wound regions within 1 month, when cultured on modified Murashige and Skoog medium (1/2-strength macro- and full-strength micro-elements) free of plant growth regulator in darkness. The combinations of 2,4-dichlorophenoxyacetic acid ((2,4-D) acid (0, 4.52 and 45.25 M) and 1-phenyl-3-(1,2,3-thiadiazol-5-yl)-urea (TDZ) (0, 0.45, 4.54 and 22.71 M) were used to test their effects on direct shoot bud formation from two types of explants (1.5-cm long intact leaf explants and 0.5-cm long leaf segment explants). In hybrid PH59, 4.54 M TDZ increased mean numbers of shoots per explant with leaf segment explants. In hybrid PH60, 4.52 M 2,4-D plus 0.45 M TDZ promoted direct shoot bud formation from leaf segment explants. In addition, three treatments (4.52 M 2,4-D, 22.71 M TDZ, 4.52 M 2,4-D plus 4.54 M TDZ) gave a higher response than control on mean numbers of shoots per explant with intact leaf explants. Healthy plantlets each with one to three roots were obtained from leaf-derived shoots after transfer onto a hormone-free medium for 22 months. These plantlets were acclimatized in a greenhouse and grew well with 100% survival rate. 相似文献

Seventeen ecotypes of the wild species Medicago polymorpha adapted to a Sardinian (Italy) environment have been evaluated for their response to tissue culture. The accession Samughero-Albi was the more respondent for callus induction and, together with Usassai, showed the highest regeneration capacity on media containing 1 mg l-1 2iP and 0.1 mg l-1 IAA. The morphogenetic response was also affected by the explant source. The hypocotyl-derived-calli were the best regenerating tissues. Regenerated plantlets were difficult to root and it was possible to obtain plants with a well developed root system only after 5–7 weeks of culture on media containing 2iP and IAA both at 0.2 mg l-1. Mesophyll cells were the best protoplast yielding source but only those isolated from roots were able to divide and to regenerate plants. Results are discussed in relation to the genotype specificity for the morphogenetic response and the feasibility of using M. polymorpha in the somatic hybridization with M. sativa.Abbreviations NAA

Summary Callus of Phalaenopsis Nebula was induced from seed-derived protocorms on 1/2 Murashige and Skoog (MS) basal medium plus 0–1.0 mg l−1 (0–4.52 μM) N-phenyl-N′-1,2,3,-thiadiazol-5-yl urea (TDZ) and/or 0–10 mg l−1 (0–45.24 μ M) 2,4-dichlorophenoxyacetic acid (2,4-D). Protocorms 2 mo. old performed better than 1-mo.-old protocorms for callus induction.
More calluses formed on 1/2 MS basal medium supplemented with 0.1–1.0 mg l−1 (0.45–4.52 μM) TDZ. These calluses could be maintained by subculturing every month with basal medium supplemented with 0.5 mg l−1 (2.27 μM) TDZ and 0.5 mg l−1 (2.26 μM) 2,4-D. Protocorm-like bodies were formed, and plants regenerated from these calluses on 1/2 MS basal medium alone or supplemented
with 0.1–1.0 mg l−1 (0.45–4.52 μM) TDZ. Plantlets were then potted on sphagnum moss in the greenhouse and grew well. No chromosomal abnormalities were found
among the root-tip samples of 21 of the regenerated plantlets that were successfully acclimatized. 相似文献

Plant regeneration from callus cultures of several soybean genotypes via embryogenesis and organogenesis 总被引:17,自引:0,他引:17
Using callus derived from immature embryos, regeneration of viable plants was obtained in soybean (Glycine max (L.) Merr.). Depending on the composition of the medium, regeneration occurred via embryogenesis or via organogenesis. Embryogenesis resulted when embryos were plated on Murashige and Skoog (MS) medium containing 43 M -naphthaleneacetic acid. In work with the cultivar Williams 82, the addition of 5.0 M thiamine HCl increased embryogenesis from 33% to 58% of the embryos plated. Addition of 30 M nicotinic acid to the MS medium enhanced embryogenesis further to 76%. Organogenesis was obtained when medium containing 13.3 M 6-benzylaminopurine, 0.2 M and -naphthaleneacetic acid and four times the normal concentration of MS minor salts was used. Histological studies of these cultures confirmed the organogenic and embryogenic nature of the cultures, by demonstrating the formation of shoot buds and somatic embryos, respectively. Similar responses were obtained in all 54 genotypes tested in this manner. The cultures retained the ability to regenerate complete plants for at least 12 months and 12–15 subcultures. Seeds have been obtained from several regenerated plants and when grown in the field these produced normal-appearing fertile plants.Abbreviations BAP

Intergeneric Fragaria vesca x Potentilla fruticosa hybrids were produced using in vitro culture. Hybrid plants were not obtained by direct embryo rescue, but were regenerated from cotyledon-derived callus. Experiments with F. vesca indicated that using cotyledon halves was not more productive than using entire cotyledons. A polarity was observed in cotyledons and in cotyledon halves, with callus and regenerated shoots produced more frequently from proximal ends. Cotyledons from 17% of hybrid embryos produced callus and regenerated mature plants. The technique enabled rapid multiplication of some embryos, with the production of more than one hybrid plant. In some cases more than 100 shoots were obtained from one embryo, demonstrating the potential usefulness of this technique for the production of intergeneric hybrids.Abbreviations BA

Plant regeneration from transformed embryogenic callus of an elite indica rice via Agrobacterium 总被引:1,自引:0,他引:1
The present study describes a simple and efficient protocol for plant regeneration from scutellar-derived embryogenic calli of an elite basmati indica rice (Oryza sativa L., cv Pusa Basmati 1) transformed with Agrobacterium. A supervirulent plasmid pTOK233 as well as a non-supervirulent plasmid pJB90GI containing -glucuronidase (gus) and hygromycin phosphotransferase (hpt) chimeric genes were used to assess transformation and regeneration efficiency. The effects of some factors like the bacterial density and inclusion of sorbitol in the medium on the co-culture and transformation have been evaluated; the procedure for selection and regeneration from transformed calli was found to be critical. Furthermore, co-culture and selection on regeneration medium was found to be better than callus medium and led to minimal media manipulations. Regeneration medium supplemented with 3% maltose was found to be better for regeneration as compared to 3% sucrose. The transformed calli were subjected to three cycles of regeneration, thus converting a higher number of transformation events into regenerants. The selected calli as well as leaf sections and roots of the transformants were GUS positive. The stable integration of the transgene was confirmed by polymerase chain reaction and Southern blot analysis of the transformants. Interestingly, the presence of three additional vir genes in supervirulent plasmid pTOK233 was not required for transformation as transformation was successful with non-supervirulent plasmid pJB90GI, although the transformation and regeneration frequency was higher with the former. This effective protocol for regeneration from transformed calli resulted in a relatively high transformation frequency. 相似文献

Tiny seeds from 5-month-old green capsules of a maudiae type slipper orchid, Paphiopedilum Alma Gavaert, were induced to form totipotent callus on 1/2 strength MS medium supplemented with 22.60 μM 2,4-D and 4.54 μM
TDZ in darkness. The callus was proliferated more and maintained without any morphogenesis on the same medium with a 2-month
interval of subculture for more than 2 years. When transferred to 1/2 MS medium supplemented with 26.85 μM NAA, an average
of 4.7 protocorm-like bodies (PLBs)/shoot buds formed from each explant after 120 days of culture. After another 72 and 240 days
of culture on the same medium, 25 shoot buds and eventually 75 plantlets were obtained through shoot multiplication from the
original culture. Kinetin at 4.65 μM was suitable for shoot multiplication and could induce an average of 3.0 shoots from
a single young shoot after 60 days of culture. The regenerated plantlets grew normally when transplanted to containers with
sphagnum moss in a shaded greenhouse. 相似文献

Callus was induced from seeds of Puccinellia distans (L.) Parl. on MS medium supplemented with 2 mgl-1 2,4-dichlorophenoxyacetic acid and 0.5 mgl-1 kinetin. Morphogenesis initiation was achieved during subculture on medium containing 0.1 mgl-1 2,4-D. From the point of morphogenetic capacity, 3 types of callus were selected. High frequency of plant regeneration was obtained by selection of embryogenic type of callus, and culture on N6 medium and N6 medium supplemented with kinetin (5–10 mgl-1), or kinetin (2 mgl-1) and IAA (0.5 mgl-1). A high ratio of albinos among regenerants was observed. 相似文献

Nodular callus was induced at a high frequency on young purple red, 5–15 mm long laminae taken from in vitro grown plants of mangosteen. The optimal medium was composed of Murashige and Skoog (MS) nutrients supplemented with 2.22
μM benzyladenine (BA), 2.25 μM thidiazuron (TDZ), 500 mg l-1 polyvinylpyrrolidone (PVP 360 000) and 3% sucrose. A multiplication rate of two–three was obtained by subculture of the nodular
callus at 3–4-week intervals. Plantlet regeneration from the nodules was achieved by transfer to woody plant medium (WPM)
with 500 mg l-1 PVP, 0.4 μM BA and 3% sucrose and overlaying with half strength liquid MS containing 0.32 μM naphthaleneacetic acid (NAA),
0.13 μM BA and 3% sucrose. Elongated shoots were rooted to 100% when wounded at the base of shoot, dipped in 4.4 mM indolebutyric
acid (IBA) solution in the dark for 15 min and cultured on WPM supplemented with 1.11 μM BA, 0.25% activated charcoal, 34.5
μM phloroglucinol (PG) and 3% sucrose.

Embryogenic callus of Japanese lawngrass (Zoysia japonica Steud.) was induced from sterile mature seeds on LS medium with 5 mg / l of 2,4-D. Embryogenic callus selected visually under microscope was proliferated in liquid N6 medium with amino acids (N6-AA medium). Protoplasts were isolated from suspension cells by the treatment of enzyme mixture containing pectolyase Y-23 and cultured in K8p medium with 2 mg / l of 2,4-D at the density of 106 / ml. Plants were regenerated by transferring the protoplasts derived callus to MS medium and incubating at 28 °C under light for two months. Plantlets were successfully transplanted in the soil.Abbreviations 2,4-D

Summary Totipotent callus of Cypripedium formosanum, an endangered slipper orchid species, was induced from seed-derived protocorm segments on a quarter-strength Murashige and
Skoog medium containing 4.52 μM 2,4-dichlorophenoxyacetic acid and 4.54 μM 1-phenyl-3-(1,2,3-thiadiazol-5-yl)-urea (thidiazuron). This callus proliferated well and was maintained by subculturing on
the same medium. On average, 13 protocorm-like bodies could be obtained from a piece of 4 mm callus after being transferred
to the medium with 4.44 μM N6-benzyladenine after 8 wk of culture. The regenerated protocorm-like bodies formed shoots and roots on medium containing 1
g l−1 activated charcoal and 20 g l−1 potato homogenate. After 24 wk of culture on this medium, well-developed plantlets ready for potting were established. 相似文献

Plant regeneration from leaf base callus of turmeric and random amplified polymorphic DNA analysis of regenerated plants 总被引:5,自引:0,他引:5
Callus cultures were initiated from leaf bases of turmeric on Murashige and Skoog's basal medium (MS) supplemented with dicamba,
picloram (2 mg l−1) or 1-naphthaleneacetic acid (NAA) (5 mg l−1) in combination with benzyladenine (BA) (0.5 mg l−1). On transfer of callus cultures to medium supplemented with benzyladenine (BA) (5 mg l−1) in combination with triiodebenzoic acid (TIBA) or 2,4-dichlorophenoxyacetic acid (2,4-D) (0.1 mg l−1), green shoot primordia were seen to differentiate from the surface of the callus. On transfer of regenerating cultures to
half MS media supplemented with Kn, shoot primordia developed into well developed shoots. When shoots were transferred to
medium devoid of phytohormones, complete rooted plants were obtained. Ninety percent of the plants survived to maturity on
transfer to soil. Random Amplified Polymorphic DNA (RAPD) analysis of eight regenerated plants using 14 primers when separated
on non-denaturing polyacrylamide gels showed 38 novel bands. About 51 bands present in the control were absent in the regenerants.
The result indicates that variation at DNA level has occurred during in vitro culture.

Plant regeneration from shoot tips and callus of papaya 总被引:8,自引:0,他引:8
Summary Two methods of in vitro culture were employed to regenerate papaya plants. One involved regeneration of plants from callus
and the other, production of multiple plants from single shoot-tip explants. Callus was induced from stem sections of papaya
seedlings in a medium containing 1 mg per 1 NAA and 0.1 mg per 1 kinetin. The callus regenerated shoots and/or embryoids when
transferred to a medium of lower auxin, 0 to 0.05 mg per 1 IAA, and higher cytokinin, 1 to 2 mg per 1 kinetin Multiple shoots
were produced when the excised shoot-tip explants were cultured in a medium supplemented with 0.05 mg per 1 IAA and either
5 mg per 1 kinetin or 0.5 to 1.0 mg per 1 benzyladenine. Root formation of the shoots or embryoids that derived from callus
or shoot tips occurred in a medium containing 5 mg per 1 IAA and in a light intensity of 3000 to 4000 Ix. The rooted plants
could be established in soil and under standard greenhouse conditions after they had been acclimated by initially growing
them in moist vermiculite contained in polyethylene-covered pots.

Induction of callus and plant regeneration in Vicoa indica 总被引:1,自引:0,他引:1
Callus cultures were initiated from the stem and leaf explants of aseptically grown Vicoa indica. A simple method is described for plant regeneration from callus and the rapid multiplication of the plants thus obtained. Callus initiation was optimum in Gamborg B5 (B5) basal medium containing either 2.0 mg l-1 naphthaleneacetic acid (NAA) with 0.2 mg l-1 kinetin (Kn) or 2.0 mg l-1 6-benzylaminopurine (BAP) with 0.2 mg l-1 NAA. The calli initiated on B5 medium were able to proliferate on both Murashige and Skoog (MS) and B5 basal medium. Shoot primordia were obtained from greenish callus on passage to B5 basal medium containing 3.0 mg l-1 BAP and 1.0 mg l-1 Kn. On further subculture onto B5 medium containing 0.2 mg l-1 Kn the shoot primordia developed into plantlets. 相似文献

Summary Callus was initiated from in vitro-grown plants of Gladiolus cultivars ‘Jenny Lee’ and ‘Florida Flame.’ The age of callus used for regeneration of plants was either 9 mo. old or 8 yr
old from ‘Jenny Lee,’ and 4 mo. old from ‘Florida Flame.’ Regeneration medium consisted of Murashige and Skoog’s basal salts
medium supplemented with 2.0 mg/l (9.3 μM) kinetin. This medium was supplemented with various concentrations of either bialaphos (Meiji Seika, Tokyo, Japan) or phosphinothricin
(Hoechst-Roussell, Frankfurt, Germany). Bialaphos was more effective than phosphinothricin at stimulating plant regeneration.
Plants regenerated from 8-yr-old callus of ‘Jenny Lee’ only when the regeneration medium was supplemented with 0.10 mg/l bialaphos.
A bialaphos concentration of 0.01 mg/l stimulated regeneration from 9-mo.-old callus of cultivar ‘Jenny Lee’ and 4-mo.-old
callus of ‘Florida Flame.’ 相似文献

Summary Young inflorescence explants of green bamboo (Bambusa oldhamii Munro) in culture show a high capacity for plant regeneration through somatic embryogenesis. Embryogenic callus was initiated from explants maintained on Murashige and Skoog's medium supplemented with 3 mg/l 2,4-D, 2 mg/l kinetin and a high content (60 g/l) of sucrose. Prolonged culture in the embryoid induction medium or transferral of embryonic callus to auxin-free medium resulted in the continued development and eventual germination of embryoids and establishment of rooted plantlets that were successfully transferred to soil. 相似文献

In order to establish and optimize an in vitro micropropagation protocol of Venus fly trap (Dionaea muscipula Ellis), a carnivorous plant, the effects of medium type, MS medium concentration, pH, and cytokinin and auxin types on shoot proliferation and root formation were investigated using 3-month-old shoots. The shoot proliferation was most effective in 2.3 M kinetin-supplemented 1/3MS medium at pH 5.5. The best conditions for rooting were 1/3MS medium supplemented with 0.5 M IBA. All subcultured shoots produced extensive root systems after 5–6 weeks culture. When plantlets after rooting were planted in plastic pots filled with 1:1 peat moss and sand, the survival rate of plantlets was almost 100%, exhibiting normal development. With subculture every 8 weeks, hundreds of the plants were propagated from a single plant within a year. 相似文献

Plant regeneration from explant and protoplast derived callus has been achieved in Medicago littoralis cv. Harbinger 1886, an annual legume resistant to the fungus Pseudopeziza medicaginis. Callus was induced from different tissue explants and the fastest growth rate was observed for hypocotyls in B5 medium with 2 mg l–1 2,4-dichlorophenoxyacetic acid and 0.5 mg l–1 N6-benzyladenine. Protoplasts were isolated from cotyledons and leaves of sterile plants and from callus; the first two kinds of protoplasts showed a plating efficiency of 5.6% and 5%, respectively, when embedded in agarose.

Plant regeneration from leaf- and cotyledon-derived calli and from protoplast-derived tissue has been obtained in Lotus pedunculatus. Callus induction was achieved with 2,4-D and plant regeneration required the following two media sequences: bud formation was stimulated by IAA and BA and shoot growth by kinetin. Root formation occurred in the presence of IAA. Cotyledon protoplasts showed a low plating efficiency and plant regeneration was achieved via an intervening callus phase.Abbreviations BA
