The acclimation of Chlamydomonas reinhardtii to anaerobiosis involves plant and animal strategies

ABSTRACT: The absence of oxygen (O2) is a stress condition for aerobic organisms and requires extensive acclimation responses. Previously, Chlamydomonas reinhardtii has been used as a reference organism for understanding these acclimation responses. In this work, we use RNA-Seq for a whole genome view of the acclimation of the organism to dark-anoxic conditions. To distinguish the responses dependent on the COPPER RESPONSE REGULATOR 1 (CRR1), which is also involved in hypoxic gene regulation, we compared the transcriptome of crr1 mutants to that of complemented strains. Nearly 10% of the genome (~ 1,400 genes) are affected by hypoxia based on pairwise comparisons of all strains and two time-points. Comparing transcript profiles from early (hypoxic) with those from late (anoxic) time-points indicated
