The identified proteins were divided into two following categories: one is regulatory proteins, for example, caffeic acid 3-O-methyltransferas, HSP70, glyoxalase I , actin, and so on. They are involved in protein biosynthesis and processing, cellular structural organization and stress responses. The other is function proteins, for instance, ascorbate peroxidase, cytoplasmic malate dehydrogenase, cytosolic phosphoglycerate kinase, S-adenosyl methionine synthetase, ATP synthase, and so on. They are involved in photosynthesis, photorespiration, redox homeostasis, and metabolisms.

通过分析可以将这些差异蛋白分为两大类：第一类是调节性蛋白，如咖啡酸三氧转甲基酶，热激蛋白70，醛酮变位酶I，肌动蛋白等，它们主要参与蛋白质的合成和加工、胁迫响应、细胞骨架稳定等过程；第二类是功能性蛋白，如抗坏血酸过氧化物酶，细胞质苹果酸脱氢酶，细胞质磷酸甘油酸激酶，S-腺苷蛋氨酸合成酶，ATP合酶等，它们则参与氧化还原平衡、光合作用、光呼吸和各种代谢等过程。

It was shown that photorespiration is often an accompanimentof photosynthesis.

植物的光呼吸是与光合作用伴随发生的。

Photorespiration is a process in which oxygen uptake and CO2 release occur in light. A C3 plant may photorespire as much as 25% of the carbon fixed by photosynthesis, such that engineering photorespiration could improve photosynthesis.

光呼吸 是绿色植物在光下吸收氧气并释放CO2的过程。C3植物光呼吸可消耗掉25％左右的光合产物，故合理改良光呼吸可望提高植物的光合效率。

与NH+4相比，NO-3提高了叶片的光呼吸速率、光呼吸速率与光合速率比值和硝酸还原酶活性。

Seven grapevine cultivars originated from different regions, i. e.'Carbernet Sauvignon' and'Queen of Vineyard'(two members of the Western Europe Cultivars Group),'Rizamat'(a member of the East Cultivars Group),'Red Double Taste'(a hybridized cultivar from Vitis vinifera L. and V. labrusca L.),'1103Paulsen','Red Globe'and 'Autumn Royal'(two new hybridized cultivars between cultivars groups which were warmly planted in recent years) were selected. After different drought stress, a combined measurement of gas exchange and chlorophyll fluorescence was conducted to evaluate the effects of drought stress to photoinhibition, as well as the role of photorespiration and xanthophyll cycle in photoprotective mechanism. After photorespiration and xanthophyll cycle were separately inhibited, the complementary effect of these two photoprotective pathways was discussed. Detached leaves of different grapevine cultivars, i. e.'Cabernet Sauvignon','Cabernet Franc','Merlot', and a rootstock,'1103Paulsen'were selected as materials, and photoinhibition degree, photorespiration activity as well as its photoprotective function under drought stress were studied. The results are as follows: 1. Under the same drought stress treatment, different photoinhibition degrees formed in different grapevine cultivars.
