Research Abstract

Plants differentiate boundary cells between organs to separate their cellular fates. To understand the molecular mechanism of organ boundary formation, I performed (1) visualization of boundary cells by using the fluorescent protein and boundary-specific genes, and (2) functional analysis of a boundary determinant CUC1 and its transcriptional targets. Two members of the ALOG gene family, LSH4 and LSH3, are direct transcriptional targets of CUC1, and both of them may be involved in meristem formation and organ separation. The ectopic expression of CUC1 resulted in the transformation of ovules to stigmatic tissue, suggesting that it controls organ identity.
