Investigation of cytokinin-deficient phenotypes in Arabidopsis by ectopic expression of orchid DSCKX1.

FEBS letters - 4 Dec 2003

Yang Shuhua, Yu Hao, Xu Yifeng, Goh Chong Jin

Abstract excerpt

The plant hormone cytokinin plays a major role in regulating plant growth and development. Here we generated cytokinin-reduction Arabidopsis plants by overexpressing a heterologous cytokinin oxidase gene DSCKX1 from Dendrobium orchid. These transgenic plants exhibited reduced biomass, rapid root growth, decreased ability to form roots in vitro, and reduced response to cytokinin in growing calli and roots....
