Protein

Transcription factor MYB20

Gene

MYB20

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

Functioni

Transcription factor that acts as positive regulator of abscisic acid (ABA) signaling in response to salt stress. Acts as negative regulator ABI1, ABI2 and PP2CA, which are protein phosphatases 2C acting as negative regulator of ABA signaling. Binds to the DNA specific sequence and core element 5'-ACGT-3' found in the promoters of ABI1 and PP2CA to negatively regulate their expression during ABA-dependent salt stress response.1 Publication

Miscellaneous

Plants overexpressing MYB20 display increased tolerance to salt stress.1 Publication
