Abstract
En 中文
• Random mutagenesis was applied to Chlorella vulgaris, an industrially relevant alga • The fm53 mutant showed decreased NPQ and constitutive zeaxanthin accumulation • A mutation on 5’ UTR of the zep gene causes the phenotype of fm53 • fm53 mutant showed decreased stability and reorganization of PSII supercomplexes • fm53 exhibited constitutive photoprotective quenching not affecting growth rate
