Characterization of flower-inducing compound in Lemna paucicostata exposed to drought stress

Abstract A flower-inducing compound, LDS1, was isolated from a free-floating aquatic plant, Lemna paucicostata . The chemical structure and the absolute stereochemistry of LDS1 were determined as (9 R ,13 R ,11 E ,15 Z )-9,13-dihydroxy-10-oxooctadeca-11,15-dienoic acid for its most abundant diastereomer. LDS1 was enzymatically produced when the plant was exposed to drought stress, and induced flowering at a concentration of 10 nM.
