Sustained downregulation of photosystem II in mistletoes during winter depression of photosynthesis

Matsubara, Shizue; Gilmore, Adam; Ball, Marilyn; Anderson, Jan; Osmond, C. Barry

Description

Cold acclimation by sustained downregulation of PSII was studied in intact leaves of an Australian mistletoe Amyema miquelii (Lehm. ex Miq.) Tiegh. and its host Eucalyptus. The trends were followed from autumn to spring on leaves that had developed in summer and were exposed to different microclimates with progress of the seasons. In sun leaves of mistletoe, efficiency of excitation energy transfer from light-harvesting pigments to Chl a molecules in PSII core complexes was markedly reduced in...[Show more]
