3β,13-Dihydroxylated C 20 gibberellins from inflorescences of Rumex acetosa L.
Using full scan GC-MS a wide range of gibberellins (GAs) was identified in the young inflorescences of the dioecious species Rumex acetosa L., consistent with the ubiquitous early 13-hydroxylation pathway in both male and female plants. In addition, R. acetosa is the first species in which all three 3β, 13-dihydroxylated C20-GAs - GA18, GA38 and GA23 - have been identified in the same organism, suggesting an early 3β,13-dihydroxylation biosynthesis pathway in this species. Authentic GA18, GA38...[Show more]
