| | ===Function=== | | ===Function=== |
| − | OsGS2 was also named as OsGLN2, λGS31 which encodes cytoplasmic glutamine synthelase GS2. Glutamine synthelase（GS）a key enzyme of assimilation process which catalyze glutamate and ammonia into glutamine at the existence of ATP[1]. It is the first reaction of nitrogen assimilation. GS2 could catalyze assimilation of amino produced by chloroplasts photorespiration[2]. | + | * The rice '''''OsGS2''''' can encode chloroplastic glutamine synthetase proteins. |
| − | | + | * The rice '''''OsGS2''''' is a key enzyme of assimilation process which catalyze glutamate and ammonia into glutamine at the existence of ATP. |
| − | ===Expression===
| + | * It is the first reaction of nitrogen assimilation. GS2 could catalyze assimilation of amino produced by chloroplasts photorespiration. |
| − | In most plants, GS2 is expressed in the tissue containing chlorophyll and some plants' roots or nodules also have the existence of GS2[2].
| + | * '''''GS2''''' might be involved in assimilation of ammonium derived from many sources such as nitrate in the soil, atmospheric N 2 , and endogenous amino acids as well as from photorespiration |
| − | | |
| | | | |
| − | Nitrogen-related genes in different rice varieties have the expression pattern of the flag leaf at different growth stages, we can see from the figure, at any time, OsGS1.1, OsGS1.2, OsGS2 are expressed in three varieties, OsGS1.1, OsGS1.2 the expression pattern of consistent, OsGS2 gene expression levels in the flag leaf of three rice varieties in the filling stage is higher, and the most obvious in the farming and Yang rice. It is worth noting that, in maturity, OsGS2 gene expression in three varieties more consistent with the filling stage, the highest expression of Yang rice, and low expression of Nipponbare, almost no expression.
| + | ===Phenotypic analysis=== |
| − | | + | * Each transgenic rice plant line showed a different accumulation level of GS2. |
| − | ===Evolution===
| + | * A transgenic plant line, G39-2, which accumulated about 1.5-fold more GS2 than the control plant, had an increased photorespiration capacity. |
| − | Please input evolution information here.
| + | * In another line, G241-12, GS2 was almost lost and photorespiration activity could not be detected. |
| | + | * Fluorescence quenching analysis revealed that photorespiration could prevent the over-reduction of electron transport systems. |
| | + | * When exposed to 150 mM NaCl for 2 weeks, the control rice plants completely lost photosystem II activity, but G39-2 plants retained more than 90% activity after the 2-week treatment, whereas G241-12 plants lost these activities within one week. In the presence of isonicotinic acid hydrazide, an inhibitor of photorespiration, G39-2 showed the same salt tolerance as the control plants. |
| | + | * The intracellular contents of NH 4 + and Na + in the stressed plants correlated well with the levels of GS2. |
| | + | * Thus, the enhancement of photorespiration conferred resistance to salt in rice plants. |

| − | We could get nucleic acid sequence and amino acid sequence data of GS2 by BLAST from NCBI database. And then using MEGA(4.0) software analyses of these data to build phylogenetic tree(figure 1)[3].
