Bean metalloprotease pvftsh2 gene and its encoded protein and application

Abstract

The bean metalloprotease PvFtsH2 gene and its encoded protein and application relate to the field of genetic engineering, in particular to a plant metalloprotease PvFtsH2 gene and its encoded protein and application. The invention provides a bean FtsH metalloprotease PvFtsH2 gene, its encoded protein and application. The nucleotide sequence of the PvFtsH2 gene is shown in SEQ ID NO: 1 in the sequence listing. The amino acid sequence of the encoded protein is shown in SEQ ID NO:2. The present invention confirms that the PvFtsH2 gene plays a role in the light-inhibition response process through plant physiology and molecular biology methods, and the mutation of the gene leads to F under light-inhibition conditions. V / F M The value decreased, the chlorophyll content decreased, and the D1 protein accumulated. The invention has important application value in increasing the yield of kidney beans by improving the utilization rate of light energy.

Description

technical field [0001] The invention relates to the field of genetic engineering, in particular to a plant metalloprotease PvFtsH2 gene and its encoded protein and application. Background technique [0002] Bean production is group production, and bean production also refers to group production. There are two main ways to increase the yield of kidney beans: one is to increase the absorption of the root system. A strong root system and a large absorption surface area are fundamental to maintaining the water and nutrients required by the stems, leaves, flowers, fruits and other organs on the ground; the other is to increase photosynthesis. 90% of the output of leguminous crops comes from photosynthesis, and the rate and efficiency of photosynthesis directly determine the yield of crops. Breeding with high light efficiency has long been a hot spot in the field of crop photosynthesis research and breeding. Improving the efficiency of light energy absorption, transmission, and c...
