Seminar: CrSBD1: A novel stress response regulator in Chlamydomonas reinhardtii

Microalgae frequently encounter oxidative stress, prompting the development of unique adaptation mechanisms. Selenium-binding proteins are implicated in environmental stress responses, although their exact role remains elusive. Herein, a global multi-omics analysis reveals the adaptation mechanisms of Chlamydomonas reinhardtii. An in-depth analysis of the role of CrSBD1, an SBP homologue, in the response to oxidative stress followed. The sbd1 mutant strain showed increased growth under mild oxidative stress conditions alongside with diminished molecular and biochemical responses, compared to the wild type. This study suggests that CrSBD1 plays a novel role in regulating early responses to oxidative stress in C. reinhardtii.
