Change of transcriptional levels of ESTs involved in VLCFA biosynthesis upon ND. +N and −N indicate prior to and after ND, respectively. Individual enzymes are numbered and whose EC# is indicated. Many enzymes are encoded by various numbers of non-redundant ESTs in B. braunii (779) or (Bot-88). a Level and ratio of individual EST involved in VLCFA biosynthesis in cells prior to (+N) and after (−N) ND are shown. Differentially transcribed ESTs upon ND are marked by asterisks on the left. b Level and ratio of group ESTs (i.e., sum of individual levels of ESTs encode the same enzyme) involved in VLCFA biosynthesis are shown. Activity whose summative level is greatly changed (i.e., fold change >2) is indicated by an asterisk.
