Abstract

Early and reliable detection of plant transformation events is essential for establishing efficient transformation protocols. We have compared the effectiveness of using the gene encoding a green fluorescent protein (GFP) and a beta-glucuronidase (gus) as reporter genes for early detection of transgene expression in explants subjected to biolistic bombardment and Agrobacterium-mediated transformation. The results indicate that gfp gene is superior to gus gene in following transgene expression in transiently transformed materials in both methods of transformation. Using GFP as the screenable marker, we have optimized sorghum transformation with respect to the conditions for transformation, type of explants, promoters, and inbreds. These optimized conditions have been used to obtain stably transformed explants for subsequent regeneration.
