Tobacco rbcL deletion mutant, which lacks the key enzyme Rubisco for photosynthetic
carbon assimilation, was characterized with respect to thylakoid functional properties and
protein composition. The ΔrbcL plants showed an enhanced capacity for dissipation of light
energy by non-photochemical quenching which was accompanied by low photochemical
quenching and low overall photosynthetic electron transport rate. Flash-induced
fluorescence relaxation and thermoluminescence measurements revealed a slow electron …
