Sorgolactone
IUPAC 名称
3-methyl-5-{[(3Z)-8-methyl-2-oxo-2H,3H,3aH,4H,5H,6H,7H,8H,8bH-indeno[1,2-b]furan-3-ylidene]methoxy}-2,5-dihydrofuran-2-one
描述
Isolated from the roots of Sorghum bicolor (sorghum) (genuine host plant for Striga subspecies)
Strigolactones are plant hormones that have been implicated in inhibition of shoot branching. Strigolactones are carotenoid-derived and trigger germination of parasitic plant seeds (for example striga from which they gained their name) and stimulate symbiotic mycorrhizal fungi. Strigolactones contain a labile ether bond that is easily hydrolysed in the rhizosphere meaning that there is a large concentration gradient between areas near the root and those further away. Sorgolactone is found in cereals and cereal products and sorghum.
