RLF, a cytochrome b(5)-like heme/steroid binding domain protein, controls lateral root formation independently of ARF7/19-mediated auxin signaling in Arabidopsis thaliana.

Abstract excerpt

Lateral root (LR) formation is important for the establishment of root architecture in higher plants. Recent studies have revealed that LR formation is regulated by an auxin signaling pathway that depends on auxin response factors ARF7 and ARF19, and auxin/indole-3-acetic acid (Aux/IAA) proteins including SOLITARY-ROOT (SLR)/IAA14. To understand the molecular mechanisms of LR formation, we isolated a recessive...
