Polycomb silencing of KNOX genes confines shoot stem cell niches in Arabidopsis.

Current biology : CB - 23 Dec 2008

Xu Lin, Shen Wen-Hui

Abstract excerpt

Most plant organs develop postembryonically from stem cells in the shoot and root meristems. In Arabidopsis, Class I KNOTTED-like homeobox (KNOX) transcription factors are specifically expressed in shoot meristems and play a primary role in the maintenance of meristem function. Although suppression of KNOX was shown to associate with histone H3K27-methylation, the molecular mechanism underlying this suppression...
