Reevaluation of Abscisic Acid-Binding Assays Shows That G-Protein-Coupled Receptor2 Does Not Bind Abscisic Acid

Scientific Correspondence Reevaluation of Abscisic Acid-Binding Assays Shows That G-Protein-Coupled Receptor2 Does Not Bind Abscisic Acid

The phytohormone abscisic acid (ABA) plays an integral role in plant growth and development, but only recently have putative receptors been identified (Razem et al., 2006; Shen et al., 2006; Liu et al., 2007; Pandey et al., 2009). Our results, however, suggest that the putative extracellular ABA receptor, G-ProteinCoupled Receptor2 (GCR2), does not bind ABA. We propose that an improved method f...

Does abscisic acid affect strigolactone biosynthesis?

SUMMARY *Strigolactones are considered a novel class of plant hormones that, in addition to their endogenous signalling function, are exuded into the rhizosphere acting as a signal to stimulate hyphal branching of arbuscular mycorrhizal (AM) fungi and germination of root parasitic plant seeds. Considering the importance of the strigolactones and their biosynthetic origin (from carotenoids), we ...
