FIG. 3.
Total ion chromatograms from GC-MS of extracts from the culture media from the wild type (A) and REMI mutant gib2 (B). Arrows in panel A indicate retention times of intermediates in the GA pathway identified in the culture medium of the wild type by GC-MS analysis as follows: 1, ent-kaurene; 2, GA9; 3, GA25 + GA24; 4, GA14; 5, GA4; 6, GA7; 7, GA13 + GA36; 8, iso-GA3 + GA16; 9, GA3.
