Cyclic electron flow and light partitioning between the two photosystems in leaves of plants with different functional types

Sagun, Julius Ver; Badger, Murray; Chow, Wah Soon; Ghannoum, Oula


Cyclic electron flow (CEF) around photosystem I (PSI) is essential for generating additional ATP and enhancing efficient photosynthesis. Accurate estimation of CEF requires knowledge of the fractions of absorbed light by PSI (fI) and PSII (fII), which are only known for a few model species such as spinach. No measures of fI are available for C4 grasses under different irradiances. We developed a new method to estimate (1) fII in vivo by concurrently measuring linear electron flux through both...[Show more]
