Abstract

Chlorophyll deficient mutants are appropriate model objects for a large number of investigations in the field of photosynthesis. In this study, we identified a state of Photosystem I (PSI) and Photosystem II (PSII) photochemistry and light responses of the sunflower yellow-green mutant line - en:chlorina-7, wherein mutations in chloroplast genes have been previously localized. The conducted research revealed low content of photo-oxidizable PSI and an impaired quantum yield of PSII photochemistry in the en:chlorina-7 line as compared with a wild type. Disturbances of PSI and PSII in yellow-green plastome mutant line of sunflower (en:chlorina-7) are associated with mutations in psaA and psbB, respectively.
