Os RAR1 Expression Is Regulated by Os Rac1.

(A) Correlation of mRNA expression levels of Os Rac1, Os RAR1, and Os SGT1. Overexpression of CA-OsRac1 strongly increased mRNA accumulation of RAR1 and SGT1 in rice cell cultures. Levels of mRNAs were measured by RT-PCR.

(B) Levels of mRNA (RT-PCR) and protein accumulation (protein gel blot [WB]) for Rac1, RAR1, and SGT1. DEX-inducible CA-OsRac1 (ICA) and an OsRac1-RNAi cell culture were examined by RT-PCR and immunoblotting after DEX induction and ethanol as a control.
