Subsets of ESTs in a number of processes and pathways are most up-regulated and down-regulated upon ND in B. braunii 779 cells. a Distribution of ESTs associated with 4 GO functions and 6 KEGG pathways based on ranks by ratio. b Distribution of ESTs associated with unspecific dehydrogenase based on ranks by level (upper panel) and ratio (lower panel). The display is identical to Fig. 5. c Levels of chlorophyll content. The bar plot shows the average level of chlorophyll contents in cells prior to (+N) and after (−N) ND. Error bar is derived from triplicates. d Efficiency of quantum yield of photosystem II. The bar plot shows the average level of efficiency of quantum yield (Y) of photosystem II in cells prior (+N) to and after (−N) ND.
