Annotated Information
Function
OsNADP-ME3 is a malic enzyme, and malic enzymes widely exist in plant.Malic enzyme is a key enzyme in the KERBS CYCLE. This is very important to the metabolism of organisms.In plants, it takes part in photosynthesis,respiration,production of lipids and other important metabolic pathways,which is very important to keep the osmotic potential of plant cells, stabilize the PH of cytoplasm and keep the ions absorption of plant roots balanced.It is one fo the most important enzymes in life activities of plants.[2][3]NADP-ME3 was overexpressed in Arabidopsis plants to observe the changes of phenotypes, and it was found that NADP-ME3 could improve plant resistance to abiotic stresses to a certain extent.
Expression
The expressions of NADP-ME3 mRNA under a variety of abiotic stresses were detected with Northern blot by extracting RNA from leaves and roots of rice with different adversity handling(figure 1). The results indicated that,under the condition of salt stress(80 mmol/L NaCl), the expression level of NADP-ME3 in the initial period of leaf stress is relatively high. With time increasing, it decreased gradually, and the decline trend was evident.Meantime, under the same condition, although the expression level is low in root at the initial stage, it gradually increased with the time prolonging, which demonstrated that there exists response relationship between NADP-ME3 and salt stress; under the condition of alkaline stress(30 mmol/L NaHCO3),in leaf, the expression level of NADP-ME3 in the initial 6 hours is relatively high, and then showed the trend of decreasing,while in root, it was increasing (6h),and then gradually decreased.After 24h,it increased again with irregular change,but at any time, it was higher than the contrast,which illustrated that OsNADP-ME3 expressed induced by NaHCO3; under the condition of drought stress(10% PEG),in leaf, the expression level of NADP-ME3 in the initial stage is highest.With stress time prolonging,the transciriptional level of mRNA decreased gradually,while in root, it is relatively high in the initial stage, and up to highest at 12h,then declined mildly.
In conclusion, at the exposure to NaCl, NaHCO3 and PEG, the expression level of NADP-ME3 changed with the different lengths of exposure duration. Therefore, the NADP-ME3 may be involved in response to abiotic stresses.
Evolution
Rice NADP-MEs are a multigene family of three cytoplasmic NADP-MEs and one plastidic NADP-ME. NADP-ME3 is of one of the cytoplasmic members . The cDNA sequence of the cloned NADP-ME3 is 2 240 bp, and the 5' untranslated region (UTR) is 151 bp while the 3' UTR is 376 bp. The open reading frame is 1 712 bp, encoding 570 amino acids.Homology analysis of the amino acid sequence in rice NADP-ME gene family(figure 2).
