Transcriptome analysis of wild type and transgenic plants with excessive stomatal lineage cells

To identify new regulators of stomatal development, we assay the transcriptomes of plants bearing enriched stomatal lineage cells undergoing active divisions. Overexpression of a truncated SPCH variant, SPCH∆49 that is insensitive to MAPK-triggered protein phosphorylation for degradation, produces excessive stomatal lineage cells in wild type and basl mutant background. Then comparative transcriptome analysis was conducted to identify noval stomata formation regulators
