Hormonal control of the shoot stem-cell niche
Original language description
The classic phytohormones cytokinin and auxin play essential roles in themaintenance of stem-cell systemsembedded in shoot and root meristems, and exhibit complex functional interactions. Herewe show that the activity of both hormones directly convergeson the promoters of two A-type ARABIDOPSIS RESPONSE REGULATOR (ARR) genes, ARR7 and ARR15, which are negative regulators of cytokinin signalling5 and have important meristematic functions. Whereas ARR7 and ARR15 expression in the shoot apical meristem (SAM) is induced by cytokinin, auxin has a negative effect, which is, at least in part, mediated by the AUXIN RESPONSE FACTOR5/ MONOPTEROS (MP) transcription factor6. Our results provide a mechanistic framework for hormonal control of the apical stem-cellniche and demonstrate how root and shoot stem-cell systems differ in their response to phytohormones.
