Microspore embryogenesis: assignment of genes to embryo formation and green vs. albino plant production.

ABSTRACT: Plant microspores can be reprogrammed from their normal pollen development to an embryogenic route in a process termed microspore embryogenesis or androgenesis. Stress treatment has a critical role in this process, inducing the dedifferentiation of microspores and conditioning the following androgenic response. In this study, we have used three barley doubled haploid lines with similar genetic background but different androgenic response. The Barley1 GeneChip was used for transcriptome comparison of these lines after mannitol stress treatment, allowing the identification of 213 differentially expressed genes. Most of these genes belong to the functional categories "cell rescue, defense, and virulence"; "metabolism"; "transcription"; and "transport". These genes were grouped into clusters a
