ARF7 and ARF19 regulate lateral root formation via direct activation of LBD/ASL genes in Arabidopsis.

The Plant cell - 1 Jan 2007

Okushima Yoko, Fukaki Hidehiro, Onoda Makoto, Theologis Athanasios, Tasaka Masao

Abstract excerpt

Lateral root formation in Arabidopsis thaliana is regulated by two related AUXIN RESPONSE FACTORs, ARF7 and ARF19, which are transcriptional activators of early auxin response genes. The arf7 arf19 double knockout mutant is severely impaired in lateral root formation. Target-gene analysis in arf7...
