Analysis of knockout mutants suggests that Arabidopsis NADP-MALIC ENZYME2 does not play an essential role in responses to oxidative stress of intracellular or extracellular origin.

Abstract excerpt

NADPH is a pivotal molecule in oxidative stress, during which it is potentially produced by several cytosolic NADP-linked dehydrogenases. This study investigated the response and functional importance of the major leaf cytosolic NADP-malic enzyme in Arabidopsis (NADP-ME2) during oxidative stress. Data from both microarray and targeted quantitative PCR analyses showed that NADP-ME2 transcripts accumulated in...
