Identification of endogenous gibberellins in inflorescence of Ornithogalum thyrsoides

Koshioka, Masaji; Roh, Mark; Nakayama, M; Mander, Lewis; Hisamatsu, Tamotsu

Description

Endogenous gibberellins (GAs) were extracted from inflorescence of Ornithogalum thyrsoides and identified by using combined gas-chromatography / mass spectrometry (GC/MS). Three 13-hydroxylated GAs, GA19, GA20 and GA53, and thirteen 13-non-hydroxylated GAs, GA4, GA7, GA9, GA12, GA15, GA24, GA25, GA51, GA61, GA112, GA115, 1,2-didehydro GA9 (which is a novel GA, and has been assigned as GA120), and GA120 - isolactone were detected. The presence of these GAs suggests that both the...[Show more]

dc.description.abstractEndogenous gibberellins (GAs) were extracted from inflorescence of Ornithogalum thyrsoides and identified by using combined gas-chromatography / mass spectrometry (GC/MS). Three 13-hydroxylated GAs, GA19, GA20 and GA53, and thirteen 13-non-hydroxylated GAs, GA4, GA7, GA9, GA12, GA15, GA24, GA25, GA51, GA61, GA112, GA115, 1,2-didehydro GA9 (which is a novel GA, and has been assigned as GA120), and GA120 - isolactone were detected. The presence of these GAs suggests that both the early-13-hydroxylation GA biosynthesis pathway and the early-13-non-hydroxylated GA biosynthesis pathway were operating in the inflorescence of Ornithogalum. The presence of GA7, GA9 and GA120 suggests that GA120 could be considered as a metabolic intermediate in the conversion of GA9 into GA7 in O. thyrsoides.
