N2 - The mechanism of post-illumination chlorophyll fluorescence transient (PIFT) was investigated in Arabidopsis. PIFT was detected in the wild type after illumination with low light. In the fba3-2 (fructose-1,6-bisphosphate aldolase) mutant, in which PIFT is enhanced, strong light also induced PIFT. PIFT was suppressed not only in the triose phosphate/phosphate translocator (tpt-2) mutant, but also in tpt-2 fba3-2, suggesting that triose phosphates, such as dihydroxyacetone phosphate (DHAP), are involved in the PIFT mechanism. We concluded that PIFT is associated with ribulose-1,5-bisphosphate (RuBP)-regeneration limitation of photosynthesis in low light.
