Plant regeneration from embryogenic cell suspension cultures of wild sorghum (Sorghum dimidiatum Stapf.)P KMythiliauthorNSeetharamaauthorV DReddyauthorA simple and efficient protocol is described for regeneration of wild sorghum (Sorghum dimidiatum) from cell suspension cultures. Fast-growing cell suspensions were established from shoot-meristem-derived callus. Plating of the suspension on Murashige and Skoog agar medium supplemented with 2.5 mg 1-1 2,4-dichlorophen-oxyacetic acid (2,4-D) resulted in the formation of embryogenic calli. High-frequency (80%) somatic embryogenesis from small cell clusters (300-400 micrometer) was observed when the cultures were initially maintained in liquid medium with reduced levels of 2,4-D (0.25 mg l-1), followed by transfer to regeneration medium. Direct plating of these small clusters on regeneration medium or transfer to liquid regeneration medium containing kinetin and 6-benzylaminopurine resulted in the development of mature somatic embryos and plantlets. The regenerants developed to maturity and were all phenotypically and cytologically norma.Sorghum1999Springer VerlagArticle
