Photoacoustic Study of Changes in the Energy Storage of Photosystems I and II during State 1-State 2 Transitions.

abstract：:The flavoenzyme ferredoxin-NADP+ reductase (FNR) is a member of the cellular defense barrier against oxidative damage in Escherichia coli. We evaluated the responses of chloroplast FNR to methyl viologen, a superoxide radical propagator, in wheat (Triticum aestivum L.) plants and chloroplasts. Treatments with the herb...
