Regulation of beta-Glucan Synthetase Activity by Auxin in Pea Stem Tissue: II. Metabolic Requirements.

abstract：:Strigolactones (SLs) are plant hormones that suppress lateral shoot branching, and act to regulate root hair elongation and lateral root formation. Here, we show that SLs are regulators of plant perception of or response to low inorganic phosphate (Pi) conditions. This regulation is mediated by MORE AXILLARY GROWTH2 (...
