Plant regeneration studies in cereals have been undertaken in immature embryos, scutellum and also in immature inflorescence tissue. The wheat mature embryos can also be employed for callusing and regeneration, as they are available throughout the year and have presently been employed for transformation studies. An efficient and reproducible method for Agrobacterium-mediated transformation of m...

Induced mutations have played an important role in the development of new plant varieties. In this study, we investigated the effects of fast neutron irradiation on somatic embryogenesis combined with plant regeneration in embryonic leaflet culture to develop new peanut (Arachis hypogaea L.) germplasm for breeding. The dry seeds of the elite cultivar Luhua 11 were irradiated with fast neutrons ...

An Agrobacterium-mediated transformation method was applied to introduce the luciferase reporter gene under the control of the CaMV35S promoter in the pGreen0049 binary vector into strawberry cv. Camarosa. The in vitro regeneration system of strawberry leaves to be used in the transformation was optimized using different TDZ concentrations in MS medium. TDZ at 16 µM showed the highest percentag...

Temperature-sensitive variants of Nicotiana tabacum were isolated from a liquid suspension culture of somatic cells by a negative selection procedure, using bromodeoxyuridine and light. A total of nine such variants have been recovered, with an estimated rate of 2 x 10(-7) per cell division. The appearance of the variants at the permissive temperature varied from nearly wild type, white and fri...

Koelreuteria elegans, popularly known as “Flame Gold” is an ornamental tree. In vitro callus induction and regeneration from various explants (eaf segments and cotyledonary leaf) were studied on modified MS medium. The highest callus induction rate (80%) and multiplication was obtained in 2 mg/l 2,4-D from leaf segments. Calli transferred in 1.5 mg/l BAP resulted in efficient shoot regeneration...

Alsophila costularis Barker (Cyathea costularis), an endangered tree fern with tree-like erect stem, attracts gardening enthusiasts as a special ornamental plant. In vitro propagation can be advantageous for germplasm conservation and commercial application of A. costularis. Here, we described in via spore culture green globular bodies (GGBs) system, well the long-term observation acclimated pl...

The present studies report in vitro propagation of a rare and medicinally important orchid Vanda testacea through foliar explants. Explants were cultured on Mitra et al. (M) medium and its combinations with cytokinins (BAP, Kn 1 mgl each) and auxin (NAA 1 mgl) individually and in combination for initiation of regeneration response, proliferation of regenerants and subsequent development of plan...

the present study reports an efficient protocol for isolation and regeneration of protoplasts from callus of fritillaria imperialis l. there is no published method recommended for protoplast isolation and regeneration from fritillaria imperialis l. a range of factors, which influence the success of isolation and regeneration of f. imperialis protoplasts, were investigated. from the results obta...
