Abstract

The invention finds that a ytxH gene (DR0105) in Deinococcus radiodurans R1 has the function of improving the adversity resistance of prokaryotes and plants. The invention constructs recombinant vectors containing the gene and the recombinant vectors are respectively transferred into prokaryotic and eukaryotic host cells. Experiments prove that the ytxH gene (DR0105) can improve the salt tolerance of prokaryotes and the transgenic plants obtained after transplanting the gene into the plants also have salt tolerance.

Description

technical field

[0001] The present invention relates to the new function of Deinococcus radiodurans R1 ytxH gene (DR0105GeneID: 1799501), in particular to the application of the gene in improving the resistance of plants to salt stress. Background technique

[0002] Soil salinization is a worldwide resource problem and ecological problem, which has attracted more and more attention. With the technical progress of molecular biology, the positioning, separation and transfer of genes have become a reality, which plays an important role in improving the salt tolerance of crops.

[0003] Deinococcus radiodurans R1 (D.radiodurans R1) has strong resistance to ionizing radiation, UV radiation, DNA damage reagents and osmotic stress, so it has become an ideal strain for studying the adaptation mechanism of microorganisms to abiotic stress, and can also be used as a research A model species for salt tolerance in higher plants (Battista et al., 2001). Derived from a large plasmid in ...
