Omics exploration of Tetraselmis chuii adaptations to diverse light regimes.
Antonie Van Leeuwenhoek
October 2024
Article Synopsis
- Microalgae, specifically Tetraselmis chuii, respond differently to various light wavelengths, affecting their growth and metabolism.
- Different filtered light regimes resulted in lower growth rates, with blue and green filters impacting growth more than red light.
- Transcriptomic changes were observed, like increased production of ribosome-related genes under green light and altered metabolite profiles, indicating that light filtering can be utilized for specific metabolic modifications in microalgae.
Selenium-binding proteins (SBPs) represent a ubiquitous and conserved protein family with yet unclear biochemical and molecular functions. The importance of the human homolog has been extensively studied as it is implicated in many cancer types and other diseases. On the other hand, little is known regarding plant homologs.

- Microalgae, like Tetraselmis chuii, face oxidative stress in nature and develop specific mechanisms to adapt.
- Exposure to 0.5-mM hydrogen peroxide (HO) severely reduced cell viability and negatively impacted photosynthetic capacity over time.
- A rapid multi-omics response within the first hour revealed significant changes in metabolism and cellular functions, indicating both immediate and long-term impacts of oxidative stress on T. chuii.
Selenium-binding proteins represent a ubiquitous protein family and recently SBP1 was described as a new stress response regulator in plants. SBP1 has been characterized as a methanethiol oxidase, however its exact role remains unclear. Moreover, in mammals, it is involved in the regulation of anti-carcinogenic growth and progression as well as reduction/oxidation modulation and detoxification.
