Plant Regeneration in Protoplast Cultures of Tylophora indica

Abstract:
Protoplasts isolated from callus tissue derived from freshly cultured stem segments of Tylophora indica (Asclepiadaceae) rapidly divided and resulted in callus. Subsequent embryoid/ shoot bud differentiation in callus was observed on MS medium supplemented with auxins and cytokinins. The embryoids/shoot buds on transfer to appropriate basal medium without growth substances grew into plantlets. Protoplasts isolated from callus tissue maintained for over five years showed divisions and subsequent callus formation but failed to regenerate plants.

Transgenic Plants
The first-ever transgenic plant was a tobacco plant developed in 1983 that showed resistance against the tobacco mosaic virus. Since then, many transgenic plants have been developed and commercialized for improving the agricultural, ornamental, and horticultural value of a crop plant. Transgenic...
