Abstract excerpt

Carotenoids play crucial roles in light harvesting and photoprotection in photosynthetic organisms, although their functions in non-model microalgae remain poorly understood. Here, we investigated the effects of constitutive zeaxanthin accumulation in the green microalga Chlorella vulgaris. A mutant strain, named fm53 (fluorescence mutant 53), was isolated by UV mutagenesis and characterized by constitutive...
