Comment

Cytokinin oxidase/dehydrogenase 2 degrades the bioactive phytohormone cytokinin. ckx2 is preferentially expressed in inflorescence meristems, flowers, leaves and culms. The expression of ckx2 is higher in Koshihikara than it is in other cultivars such as Habataki, NIL-Gn1a and 5150; this higher level of expression is correlated with increased grain number; ckx2 increases grain number by 21%. ckx2 plays a role in regulating cytokinin levels in the vascular system of developing culms.
