Proton-mediated photoprotection mechanism in photosystem II
Frontiers in Plant Science, 2022 Photo-induced charge separation, which is terminated by electron transfer from the primary quinone QA to the secondary quinone QB, provides the driving force for O2 evolution in photosystem II (PSII).

The photoinhibition of malate dehydrogenase [PDF]
FEBS Letters, 1972 Recently several enzymes which require FMN as a cofactor have been shown to be inhibited by blue light in the presence of added FMN [l-3] . Photoinactivation of the enzyme protein occurred via the formation of triplet FMN. The present paper reports, for the first time, an FMN-mediated photoinhibition of NAD-malate dehydrogenase, a key enzyme of the ...

Seed traits of species from South Brazilian grasslands with contrasting distribution [PDF]
Acta Botânica BrasílicaSouth Brazilian grasslands are among the most species-rich grasslands worldwide yet they have been suffering ongoing degradation due to land-use. Little is known about the reproductive ecology of the native species of these grasslands. Thus, our goal was
