AHP6 inhibits cytokinin signaling to regulate the orientation of pericycle cell division during lateral root initiation.
In Arabidopsis thaliana, lateral roots (LRs) initiate from anticlinal cell divisions of pericycle founder cells.The formation of LR primordia is regulated Roller Skate Gear antagonistically by the phytohormones cytokinin and auxin.It has previously been shown that cytokinin has an inhibitory effect on the patterning events occurring during LR forma
