1 Photorespiration is an important metabolic process in C3 plants.

2 The photorespiration of C3 plants may consume 25% of the carbon fixed by photosynthesis, so engineering photorespiration could improve photosynthesis.

3 Screening and use of photorespiration mutants is the best way to study the metabolism and functions of photorespiration.

4 When C3 plants are under environmental stress, photorespiration corresponds to metabolism which eludes the stress, especially when the environmental stress is severe.

5 Photorespiration is an important metabolic process in C3 plant, which is one of the highlight of research on photosynthesis.

6 Hence photorespiration of C3 plants under environmental stress leads to a new direction of research in environmental ecology and photorespiration.

7 Under the nitrate nutrients, the photorespiration of leaf was obviously higher .

8 Thus C4 plants lessen photorespiration by carrying out photosynthesis only in cells that are insulated from high levels of CO2.

9 Photorespiration of C3 crops is high, but photosynthesis is low.

10 Most plants are C3 plants; they experience decreased carbohydrate production under hot, dry conditions as a result of the effects of photorespiration.

11 In this study, after obtaining lots of chlorophyll deficient mutants, a gene relation to photorespiration was cloned and the functions were studied.

12 Furthermore,[www.Sentencedict.com] with the deficiency of the chlorophyll content allocation of photosynthetic electron transport to photorespiration was enhanced.

13 The reduction of dissolved oxygen resulted in a decreased photorespiration in alga cells and hence an increased photosynthesis, and consequently an enhanced growth rate and biomass accumulation.

14 The activity of glycolate oxidase in mulberry leaves is an important index for selection of varieties with low photorespiration.

15 The curve pattern showed that the ratio of dark-respiration to photorespiration increased at first and decreased later on.

16 A balance is reached between the CO2 captured by photosynthesis and the one released by respiration and photorespiration .

17 They are characterized by high carbon dioxide compensation points owing to PHOTORESPIRATION .

18 Screen and utilization of the photorespiratory mutants is a best way for studying metabolism and functions of photorespiration .
