Phenotypic and transcriptomic response to sulfur deprivation. a Average ± SD (n = 3) growth in TAP (circles) and dSTAP (squares). b Time course of average ± SD (n = 3) starch accumulation. c Time course of average ± SD total lipid accumulation. d Time course of average (n = 3) total lipid yield (% DW). e Heat map of relative expression levels of autophagy-related genes. Values are indicated as the fold change (log2-ratio) of transcript levels under sulfur-deprived conditions relative to sulfur-replete conditions for the three culture phases (early and late log phases and stationary phase). The dendrogram represents hierarchical clustering based on expression values. TAP (solid line) and dSTAP (dashed line) lines are fitted curves as described in “Methods”. Real values and descriptions of autophagy-related genes are as in Additional file 7
