Research Abstract

The CPC family genes regulate root hair and trichome cell differentiation in Arabidopsis. We identified CPC homologous gene from the tomato genome and named it SlTRY. After transformation into Arabidopsis, SlTRY induced root hair differentiation and inhibited trichome formation as observed in 35S:CPC plants. In addition we show that anthocyanin accumulation was repressed in CPC::SlTRY transgenic plants.
