Expression -- Description ? help Back to Top
Source	Description
Uniprot	DEVELOPMENTAL STAGE: Specifically and transiently expressed in root endodermal cells overlying the early stages of lateral root primordia formation. {ECO:0000269\|PubMed:24902892, ECO:0000269\|PubMed:25482809}.

Functional Description ? help Back to Top
Source	Description
UniProt	Transcription factor that acts as negative regulator of lateral root (LR) development. Required for normal auxin responses during LR development. May be part of a negative feedback loop stimulated specifically in the endodermis upon LR initiation to ensure that LRs are formed only in the correct place. {ECO:0000269\|PubMed:24902892}.
