Abscisic acid is a powerful signaling molecule that accumulates in response to abiotic stress. However, no potential receptors that could perceive this increase in abscisic acid had been identified until recent reports of three abscisic acid binding proteins: the nuclear protein Flowering Time Control Locus A, the chloroplast protein Magnesium Protoporphyrin-IX Chelatase H subunit, and the membrane-associated protein G Protein Coupled Receptor 2. Abscisic acid metabolism also has a new and… CONTINUE READING
