Abstract excerpt
The Arabidopsis class-1 KNOX gene SHOOT MERISTEMLESS (STM) encodes a homeodomain transcription factor essential for shoot apical meristem (SAM) formation and sustained activity. STM activates cytokinin (CK) biosynthesis in the SAM, but the extent to which STM function is mediated through CK is unclear. Here we show that STM inhibits cellular differentiation and endoreduplication, acting through CK and the...
