TLDR GLABRA 2 controls ethylene production to help root hair growth during nutrient deficiency.
The study investigates the role of the transcription factor GLABRA 2 (GL2) in regulating ethylene (ET) production during root hair growth in Arabidopsis under nutrient deficiency. GL2 inhibits ET production by binding to the promoter of the ET OVERPRODUCER 1 (ETO1) gene, which is crucial for ET regulation. This GL2-ETO1 module is essential for root hair growth under nitrogen, phosphorus, and potassium deficiencies. The research also identifies several genes involved in this regulatory mechanism, highlighting a key transcriptional control of ET production in response to nutrient stress.
