Abstract excerpt

In this study, we aimed to understand the role of cyclic electron transport (CET) in the acclimation process in response to high salinity stress by comparing wild-type Chlamydomonas reinhardtii with CET deficient mutants, Proton Gradient Regulation 5 (PGR5), and Proton Gradient Regulation Like 1 (PGRL1). Cells grown in photoautotrophic conditions under salt stress resulted in a primary reduction in growth and...
