Higher concentration of Q(B)-nonreducing photosystem II centers in triazine-resistant Chenopodium album plants as revealed by analysis of chlorophyll fluorescence kinetics
Plants resistant to triazine-type herbicides are known to be altered in their photosystem II reaction center. Serine at site 264 in D1 protein is replaced by glycine. The measurements of chlorophyll a fluorescence excitations with a variable number of saturating flashes in Chenopodium album plants s...
