Abstract

The invention relates to the technical field of genetic engineering, in particular to a jujube glutathione peroxidase gene. The nucleotide sequence and amino acid sequence of the gene are shown by SEQ ID NO:1 and SEQ ID NO:2 in the sequence table. In the invention, a plant expression vector is constructed, a transgenic arabidopsis plant is obtained, and the salt tolerance and drought tolerance ofthe plant are evaluated to prove that the stress resistance of the plant is improved by transferring the gene into the plant as a target gene, thereby being of great practical significance to the plant variety improvement; and further study on the stress resistance mechanism of the plant with good resistance is conducive to making clear the molecular structure, expression, function and control ofthe adversity related gene, provides certain experiment data and lays theoretical foundation for further sufficiently using the good-resistance genes to improve the stress resistance of the plant, ishelpful to understanding the effect of GPXs in the signal transduction of plant active oxygen, and promotes understanding of people about the active oxygen serving as a signal molecular.

Description

technical field

[0001] The invention relates to the technical field of genetic engineering, in particular to a jujube glutathione peroxidase gene. Background technique

[0002] Mills first discovered that GPX, which has antioxidant effects in animal cells, is believed to be a defense against hemolysis caused by red blood cell oxidation, and named it glutathione peroxidase. In the past, it was considered to be the classic GPX, and now the enzyme with this function is named GPX-1. Later, the Flohe research group purified and analyzed the enzymes distributed in cells and acting on various organic peroxides and H 2 o 2 GPX, studies have shown that it is a tetramer composed of 4 protein subunits, each subunit contains 1 selenocysteine, and it forms the oxidation of the enzyme in the form of ionized selenol Restore the active center. A large number of studies have shown that mammalian GPXs have high catalytic activity and can quickly remove excess reactive oxygen species (ROS)...
