TLDR MYB30 and EIN3 work against each other to control root hair growth and phosphorus uptake in plants when phosphate is low.
The study investigated the role of the MYB30-EIN3 module in regulating root hair (RH) growth and phosphorus uptake in Arabidopsis under phosphate (Pi) deficiency. It was found that MYB30 and EIN3 have opposing effects on RH growth by transcriptionally regulating the gene RSL4 and other phosphate starvation response (PSR) genes. This antagonistic interaction allows for a finely tuned response to Pi deficiency, enhancing the plant's ability to utilize Pi resources from the soil.
