Plant Regeneration from Protoplasts of Coriandrum sativum

Calli produced from stem segments of seedling of Coriandrum satwum which were cultured on MS agar medium containing NAA 1.0mg/L. The embryogenic cell colony suspension was estabilished on MS liquid medium containing NAA 1.0mg/L%2,4-D 0.2mg/L+BA 0.5 mg/L. The cell suspension culture was used for protoplast preparation. Protoplasts were obtained in the enzyme mixture containing 2.0% Onozuka R-10, 1.0% pectinase, 0.5% snailase, 0.5% dextran sulfate potassium Salt, 0.6mol/L mannital CPW solution at pH 5.8 and 25℃. Cultured in a KM8P liquid medium containing NAA 1.0mg/L+2,4-D 0.2mg/L+6-BA 0.5 mg/L, glucose 0.4mol/L and CM 20mi/L; the protoplasts entered the stage of derision after three days, cell clusters formed in 10 days and calli formed after about 50 days. When the calli were transferred to MS agar medium containing many growth substances, they differentiated into embryoids, and then developed into plantlet with many green leaves and roots on the 1/2 MS agar medium.

Embryogenesis and plant regeneration from unpollinated ovary culture of <Emphasis Type="Italic">Psoralea corylifolia</Emphasis>

Embryogenesis and plant regeneration was achieved from callus cultures derived from unpollinated ovaries of Psoralea corylifolia L. Callus was initiated from unpollinated ovaries on Murashige and Skoog (MS) medium supplemented with 2.2 μM N ⁶-benzyladenine (BA) and various concentrations of α-naphthaleneacetic acid (NAA (2.7 to 10.7 μM) or 2,4-dichlorophenoxyacetic acid (2,4-D (2.3 to 9 μM) alone or in combination. Highly organized embryogenic callus induction, embryo development, proliferation and maturation were achieved on transfer of callus clumps to MS medium supplemented with NAA (0.27 μM) or 2,4-D (0.23 μM) alone or in combination with BA (2.2 to 8.8 μM). Addition of abscisic acid (ABA) (0.95 to 5.8 μM) to the medium enhanced average numbers of cotyledonary stage embryos, the maximum number (34.6 ± 0.7) being obtained on MS medium containing 0.27 μM NAA, 2.2 μM BA and 3.8 μM ABA. Embryos germinated on MS medium supplemented with BA (0 to 8.8 μM). MS medium containing gibberellic acid (GA₃ (0.29 to 5.8 μM) enhanced embryo germination frequency, the highest frequency (66.7 %) occurring on MS medium containing 2.2 μM BA and 4.3 μM GA₃. Effect of several concentrations (3.0 to 6.0 %) of sucrose or maltose was also observed on germination of embryos. MS medium enriched with maltose supported high frequency of embryo germination.

Protoplast culture and plant regeneration from Brassica carinata Braun

Protoplasts isolated from hypocotyls of three-day-old seedlings of Brassica carinata (Braun) cv R-2128 were cultured in a modified Nitsch and Nitsch liquid medium containing 13% sucrose, 0.4% Ficoll, 0.25 mg/l BA, 0.5 mg/l NAA and 0.5 mg/l 2,4-D. The density of medium caused the protoplasts and the developing microcalli to float on the surface of the liquid medium whereas all debris and lysed cells sank to the bottom of the culture plate. After 4–6 weeks developing microcalli were approximately 0.5 mm in diameter and were transferred onto MS medium containing 3% sucrose, 0.4% agarose, 200 mg/l casein hydrolysate, 5 mg/l BA and 0.5 mg/l NAA, pH 5.7. Approximately 20% of the calli transferred to this medium produced plantlets.Abbreviations BA 6-Benzylaminopurine - NAA 1-naphthaleneacetic acid - IAA indole-3-acetic acid - 2,4-D 2,4-dichlorophenoxyacetic acid - MS Murashiqe-Skoog

Micropropagation of squill (Charybdis numidica) through nodule culture

A micropropagation protocol for squill (Charybdis numidica, Hyacinthaceae) was developed using nodule culture. Nodule formation on leaf sections was induced in liquid Murashige and Skoog (MS) medium supplemented with 20 microM N6-benzylaminopurine (BA) under dark conditions. Nodules were cultured on semi-solid MS medium with factorial combinations of BA (0-40 microM) and alpha-naphthaleneacetic acid (NAA) (0-10 microM) under continuous light. Shoot regeneration from nodules occurred at varying degrees on all media. The highest number of shoots was formed on medium containing 2.5 microM NAA and 20 microM BA, while the maximum number of regenerated bulblets per gram nodule was induced on culture medium supplemented with 2.5 microM NAA alone. Regenerated shoots were successfully rooted at approximately 92% on semi-solid MS medium supplemented with 10 microM indole-3-acetic acid (IAA). Plantlets could be hardened and grew well after transfer to the greenhouse. Chemical analyses showed consistent bufadienolide patterns from cloned plantlets and the mother plant.     

Plantlets from somatic callus tissue of the East Indian Rosewood (Dalbergia latifolia Roxb.)

Callus-mediated shoot bud formation was demonstrated in Dalbergia latifolia Roxb. (East Indian Rosewood). Cultures were raised from shoot explants of six year-old plants on Murashige and Skoog (MS) medium supplemented with naphthaleneacetic acid (NAA) and benzyladenine (BA). A sequential treatment of callus with increasing BA levels and decreasing NAA ensured shoot bud induction. Rooting of shoots was achieved by a three-step culture procedure involving 1) White's(W) liquid medium containing indoleacetic acid (IAA), naphthaleneacetic acid and indolebutyric acid (IBA), 2) half-strength MS agar-solidified medium with charcoal (0.25%) and 3) half-strength MS liquid medium.Abbreviations BA Benzyladenine - IAA Indoleacetic acid - IBA Indolebutyric acid - MS Murashige and Skoog - NAA a-naphthaleneacetic acid - PVP Polyvinylpyrrolidone - W White's medium - 2,4-D 2,4-dichlorophenoxyacetic acid
