Abstract
The invention relates to the technical field of plant cultivation, and particularly discloses application of an effector protein expressed by an effector RxLR129113 to promoting of plant growth. Through in-depth research on the effector protein expressed by the effector RxLR129113, plant seeds are soaked in a solution containing the effector protein, and it is delightedly found that the effector protein has a significant positive effect in promoting plant seed germination and sprout growth, and it is found that the solution containing the effector protein can stimulate the growth and development of plant root systems after being added to a plant seedling raising substrate, thereby promoting the development and growth of seedlings.
Description
technical field [0001] The invention relates to the technical field of plant cultivation, in particular to the application of the effector protein expressed by the effector factor RxLR129113 in promoting plant growth. Background technique [0002] People's long-term dependence on chemical fertilizers to promote plant growth and increase yields has also brought some problems. Such as: (1) cause the increase of nitrogen and phosphorus content in water, make rivers, lakes, inland sea eutrophication, lead to algae overgrowth, water quality deterioration, fish and other aquatic organisms die in large numbers; (2) long-term excessive and simple application of chemical Fertilizers acidify the soil. The amount of ammonium ions in the soil solution and the organic and inorganic complexes on the soil micromass increases, the soil structure is destroyed, and the soil is compacted, which directly affects the cost of agricultural production and the yield of crops; (3) makes food, feed a...
