Regulation of myrosin cell development by a transcription factor, WSB, in Arabidopsis

Idioblast myrosin cells are involved in the chemical defense strategy in Brassicales. Guard cells are required for the gas exchange in land plants. Interestingly, bHLH type transcription factor, FAMA, regulates the differentiation of both myrosin and guard cells. Recently, we identified a transcription factor, WASABI MAKER (WSB), which was a direct target of FAMA. To identify genes controlled by WSB directly, we performed ChIP-seq analyses of WSB.
