Cytokinin-induced somatic embryogenesis and plant regeneration in Corydalis yanhusuo (Fumariaceae) — a medicinal plant

In vitro propagation of an endangered medicinal herb Chlorophytum borivilianum Sant. et Fernand. through somatic embryogenesis

“…In the present study optimal somatic embryogenesis was observed after reducing the concentration of 2, 4-D. Contrarily induction and development of embryos upto the torpedo-cotyledonary stages was achieved on the same auxin medium indicating the relative insensitivity to this inductive hormone in Macrotyloma uniflorum (Varisai et al 2004). Even addition of cytokinins as the sole plant growth regulator has proved to be effective in inducing somatic embryogenesis (Sagare et al 2000). In most of the cases, however cytokinin addition should be coupled with that of auxins to obtain the desired effect (Merkle et al 1995).…”

Plant Tissue Culture: Current Status and Opportunities

“…It is rapid propagation processes that can lead to the production of plants virus free [5]. Coryodalis yanhusuo, an important medicinal plant was propagated by somatic embryogenesis from tuber-derived callus to produce disease free tubers [6]. Meristem tip culture of banana plants devoid from banana bunchy top virus (BBTV) and brome mosaic virus (BMV) were produced [7].…”

Molecular aspects of somatic-to-embryogenic transition in plants

“…Various systems have been exploited to understand the mechanisms of gene regulation during SE and carrot has served as the model system [26,42,73,74,150,152,228]. Analysis of the proteome and transcriptome has led to the identification and characterization of certain genes involved in SE [7,21,22,26,57,77,107,154,158,167,187,207,220,226]. Most of these genes, however, are upregulated only in the late developmental stages, suggesting that they do not play a direct role in the vegetativeto-embryogenic transition.…”
