Transcription factor MYB77

Gene

MYB77

Organism
Arabidopsis thaliana (Mouse-ear cress)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

Transcription factor involved in auxin response. Functions in auxin signal transduction and modulates lateral root growth. Interacts with ARF response factors to promote auxin-responsive gene expression (PubMed:17675404). In response to auxin, binds sequence-specific motifs in the promoter of the auxin-responsive gene IAA19, and activates IAA19 transcription. The IAA19 transcription activation by MYB77 is enhanced by direct interaction between MYB77 and PYL8 (PubMed:24894996).2 Publications

Miscellaneous

Plants overexpressing MYB77 exhibit stunted roots and shoots.1 Publication
