Sorgomol

Sorgomol ((+)-Sorgomol) (2 pM-2 nM) stimulates 50% germination of Striga hermonthica seeds, and its activity against S. hermonthica is approximately 1000-fold that against Orobanche minor^[2].
Sorgomol (1 week-48 h) is the major root exudate strigolactone among 36 Sorghum bicolor genotypes, with the highest relative proportion (40-44%) in Hariri, Bari, Fakimustahi, Dari, and Naten^[3].
Sorgomol (0.02 μM-48 h) induces 57% germination of preconditioned Striga hermonthica seeds^[3].
Sorgomol secretion across 22 sorghum genotypes correlates with in vitro Striga germination at r = −0.17, correlates with the number of Striga plants per pot at r = 0.23, and has a stepwise regression coefficient of 0.25 for Striga emergence^[3].
Sorgomol (2 weeks of phosphorus deficiency) root exudate levels are positively correlated with D27 expression in Fakimustahi, IS9830, Tetron, and SRN39 (r = 0.73)^[3].
Sorgomol (10 nM; 24 h) is a potent germination inducer of S. hermonthica, producing > 50% germination at 10 nM^[4].
Sorgomol (10 nM-1 µM; 48 h) does not significantly induce S. gesnerioides seed germination at 10 nM or 1 µM^[4].
Sorgomol (10 nM-1 µM; 48 h) strongly inhibits S. gesnerioides seed germination induced by 10 nM ent-2′-epi-orobanchol (5 h)^[4].
Sorgomol (1 week-48 h) is produced in the root exudates of 20 sorghum genotypes and is the major strigolactone in Hariri, being roughly comparable to 5-deoxystrigol in Fakimustahi and Naten^[5].
Sorgomol (48 h) concentration in root exudates of 20 sorghum genotypes is negatively correlated with the Striga tolerance index (r = −0.32) and weakly positively correlated with the number of emerged Striga plants per pot (r = 0.23)^[5].
