Abstract

The invention discloses a transgenic plant breeding method for increasing the number of root nodules and promoting the development of root nodules, overexpressing the gene shown in SEQ ID NO: 1 or SEQ ID NO: 2 in the sequence list in the plant or its homologous / equivalent Genes to obtain transgenic plants with increased number of nodules and / or enhanced nodule development compared to normal plants. Using the method of the invention to construct transgenic plants can significantly increase the number of root nodules and promote the maturity of root nodules, and has great practical value in theoretical research and agricultural and forestry applications.

Description

technical field

[0001] The invention relates to the technical field of genetic engineering, in particular to genes related to plant nodulation and nitrogen fixation and applications thereof. Background technique

[0002] Soybean plays an important role in the national economy. Its unique symbiotic nitrogen fixation ability can convert nitrogen in the air into ammonia nitrogen that can be absorbed and utilized by plants, which not only provides the necessary nitrogen nutrition for its own growth and development, but also helps reduce Environmental pollution caused by excessive fertilization. Making full use of the symbiotic nitrogen fixation ability mediated by soybean root nodules, mining and improving the efficiency of soybean symbiotic nitrogen fixation has become one of the important ways for the sustainable development of agriculture.

[0003] Root nodules are places for symbiotic nitrogen fixation, and the number of root nodules, especially the number of root nodules w...
