strigolactone

plural strigolactones

1. uncountableusuallychemistryAny of a family of terpenoid lactones that stimulate germination in parasitic plants of the genus Striga, and that inhibit shoot branching.

   The first strigolactone isolated from root exudates was strigol (Cook et al. 1966).

Davies (editor), Plant Hormones: Biosynthesis, Signal Transduction, Action!, page 513, Orthologous strigolactone response mutants (max2/ore9 in Arabidopsis, rms4 in pea, d3 in rice) have been of major value to demonstrate the specificity of action of strigolactones (13, 22).

   Strigolactones are produced by the non-mycorrhizal plant Arabidopsis thaliana (Westwood 2000; Goldwasser and Yoder 2001), and plant mutants defective for strigolactone production have not yet been obtained.
