The corresponding relationship between roles of NADP-malic enzymes and abiotic stress in plants

Many proteins play important roles in production of metabolic energy and plant growth. NADP-malic enzyme is one of these proteins. It mainly locates on cell and organelle membrane. It not only takes part in the process of photosynthesis, but also joins the improving of plant stress tolerance. In this review, we stated the variation of the NADP-malic enzyme activity and the photosynthesis rate of plant under some main abiotic stresses (drought, salt and temperature stress). It is demonstrated that the activity of NADP-malic enzyme is increasing under different stresses, which was used to prevent the decline of plant photosynthesis to resist stresses. The expression of the NADP-malic enzyme gene, which is dissimilar under different stresses, is another point in this paper. At the same time, the enzyme in C4, CAM and C3 plant have different expression intensity under the same stress. We analyzed the mechanisms how NADP-malic enzyme to resist stresses by combined theory with experimental fact.
