HPS4/SABRE regulates plant responses to phosphate starvation through antagonistic interaction with ethylene signalling.

abstract：:Many stresses are associated with increased accumulation of reactive oxygen species (ROS) and polyamines (PAs). PAs act as ROS scavengers, but export of putrescine and/or PAs to the apoplast and their catabolization by amine oxidases gives rise to H2O2 and other ROS, including hydroxyl radicals ((•)OH). PA catabolizat...
