  • Laugier, E.; Tarrago, L.; Santos, C.V.; Eymery, F.; Havaux, M.; Rey, P.
    Arabidopsis thaliana plastidial methionine sulfoxide reductases B, MSRBs, account for most leaf peptide MSR activity and are essential for growth under environmental constraints through a role in the preservation of photosystem antennae (2010), Plant J., 61, 271-282.

General Information

General Information Comment Organism
malfunction the concomitant absence of both protein isoforms MSRB1 and MSRB2 results in a reduced growth for plants cultivated under high light or low temperature, double mutant lines restored for MSRB2 expression display no phenotype, the absence of plastidial MSRBs is associated with an increased chlorophyll a/b ratio, a reduced content of Lhca1 and Lhcb1 proteins, and an impaired photosynthetic performance Arabidopsis thaliana
