TranscriptomicsA revised mineral nutrient supplement increases biomass and growth rate in Chlamydomonas reinhardtii
Interest in exploiting algae as a biofuel source and the role of nutrient deficiency in inducing triacylglyceride (TAG) accumulation in cells necessitates a strategy to efficiently formulate species-specific culture media that can be easily manipulated. Using the reference organism Chlamydomonas rei...

TranscriptomicsZinc deficiency impacts CO2 assimilation and disrupts copper homeostasis in Chlamydomonas reinhardtii
Zinc is an essential nutrient because of its role in catalysis and in stabilizing protein structure, but excess zinc can also be deleterious. Four nutritional zinc states have been identified in the alga Chlamydomonas reinhardtii: zinc toxic, zinc replete, zinc deficient and zinc limited. Growth is ...

TranscriptomicsChanges in membrane lipid composition during Iron depletion and starvation in Chlamydomonas reinhardtii
C. reinhardtii cells exposed to abiotic stresses (e.g. iron-, nitrogen-, zinc- or phosphorus-deficiency) accumulate TAGs which are stored in lipid droplets. Here, we report that iron starvation leads to formation of lipids bodies and accumulation of TAGs. This occurs between 12 and 24 h of iron-star...

TranscriptomicsSystems analysis of Chlamydomonas Cu nutrition reveals connections between Cu and multiple O2-dependent metabolic steps
We used digital gene expression (NlaIII sequence tags) and RNA-Seq to compare the transcriptomes of Cu-replete vs. Cu–deficient Chlamydomonas wild-type cells to reveal dozens of mRNAs whose abundance is modified. Half of the corresponding genes are targets of CRR1, a master regulator of nutritional ...
