The invention relates to a method for the production of plants with suppressed photo-respiration and improved CO2 fixation. In particular, the invention relates to a re-use of phosphoglycolate produced in photorespiration. The reaction product will be converted to a component that may be reintegrated into the plant assimilatory metabolism inside the chloroplast. This is accomplished by the transfer of genes derived from glycolate-utilizing pathways from bacteria, algae, plants and / or animals including humans into the plant nuclear and / or plastidial genome. The method of the invention leads to a reduction of photorespiration in C3 plants and by this will be of great benefit for food production especially but not exclusively under non-favourable growth conditions.

Plants are provided with increased ribulose-1,5-bisphosphate (RuBP) regeneration capacity during the Calvin cycle through increased expression of sedoheptulose 1,7 bisphosphatase, in combination with reduced photo-respiratory losses through expression of glycolate catabolizing enzymes. Such plants have a greater growth rate and / or improved biomass and / or increased carbon fixation compared to untreated plants, or plants comprising only one of the features above.

The invention provides a special fertilizer for maize and a preparation method of the special fertilizer. The special fertilizer for the maize is prepared from components as follows: 35%-45% of urea, 5%-15% of diammonium phosphate, 15%-25% of superphosphate, 10-20% of potassium chloride, 3%-7% of zinc sulfate and 3%-7% organic acid. The special fertilizer for the maize can improve the situation of uneven maize fertilization, has a proper ratio of nitrogen fertilizer to phosphorus fertilizer to potassium fertilizer to zinc fertilizer, helps growth of the maize, can affect synthesis of auxin in plant bodies, catalyzes the photochemical reaction of chlorophyll, and promotes photorespiration of the maize. Meanwhile, the properties of adversity resistance, lodging prevention, low-temperature damage prevention and the like of the maize can also be improved. The special fertilizer for the maize can not only increase maize yield, but also improve the maize quality and economic benefits.

The present invention relates to the field of plant molecular biology and concerns methods for enhancing the abiotic stress tolerance in plants by modulating the expression of the glyoxylate reductase gene. The present invention also provides chimeric constructs useful in the methods in the invention. In addition, the invention provides transgenic plants having an enhanced abiotic stress resistance, in particular an enhanced tolerance to high light conditions and an improved CO2 fixation.

The invention belongs to the field of plant biotechnology, and in particular relates to a compound photorespiration inhibitor and its preparation method and application. The compound photorespiration inhibitor includes sodium bicarbonate with a concentration of 50mg / L to 500mg / L, sodium bisulfite with a concentration of 50mg / L to 500mg / L, and bile chloride with a concentration of 50mg / L to 500mg / L. Alkali, Tween-80 with a concentration of 0.5% to 1.5%. The present invention organically combines three kinds of photorespiration inhibitors, and adds a spreading agent, which is beneficial to the absorption of medicaments, exerts their respective effects of inhibiting photorespiration and the synergistic inhibition between them, and reduces the degree of photorespiration , significantly improving crop yield and quality.

The invention relates to a preparation method and application of a nano-carbon dioxide capture agent. The preparation method of the nano-carbon dioxide capture agent of the present invention uses cationic surfactant-modified bentonite as a carrier, and supports cationic surfactant-modified chitosan and graphene oxide. And loading organic base modified hydrotalcite to prepare CO 2 The nano-capture agent has the photocatalytic effect of nano-materials, captures and aggregates carbon dioxide in the air and enriches around the leaves and stems for absorption and utilization by crops, enhances photosynthesis, increases photosynthetic rate, inhibits photorespiration at night, synthesizes chlorophyll for crop growth, and accumulates crops The three elements of carbon, hydrogen, and oxygen necessary for growth can effectively absorb, synthesize, and transform organic components such as nitrogen, phosphorus, and potassium in the soil, and fully promote the breeding, growth, and maturity of crops to increase production and income; the CO of the present invention 2 The capture agent can be used for facility crops as well as field crops. This kind of CO under normal temperature and pressure 2 Catchers have a wide range of applications.
