Gene for increasing plant drought resistance and salt resistance and enconding product and application thereof

Abstract

The invention relates to a gene for increasing plant drought resistance and salt resistance and an encoding product and an application thereof and discloses a gene LaAsr1 which is related to litchi resistance and is one of nucleotide sequences as follows: 1) the DNA sequence in the <400>1 term in the sequence table; 2) protein in the <400>1 term with the amino acid residue sequence in the <400>2 term or the derived protein with the same activity of the amino acid residue sequence in the <400>2 term by replacing, deleting or adding one or more of amino acid residues to the amino acid residue sequence in pseudo column. The gene can be induced to express by water stress and salt stress and can increase the plant drought resistance and salt resistance, thus having an important theoretical and practical significance for cultivating good plant types and increasing anti-microbial effect of plants by regulating the gene.

Description

[technical field] [0001] The present invention relates to acquisition of litchi Asr (abscisic acid-, stress-, and ripening-induced gene, Asr) sequence, expression analysis, construction of plant expression vector and transformation of Arabidopsis thaliana to identify drought resistance and salt tolerance. [Background technique] [0002] Asr (abscisic acid-, stress-, and ripening-induced gene) (abscisic acid-, stress-, and ripening-induced gene) is a class of genes discovered in plants in recent years, since Iusem et al first isolated tomato Asr1 from tomato fruit (Iusem et al., 1993), many Asr cloned in different plants, such as: apricot (Mbeguie-A-Mbeguie et al., 1997), lily (Wang et al., 1998; Chang et al., 1999), Rice (Vaidyanathan et al., 1999), pear (Itai et al., 2000), grape (Cakir et al., 2003), ginkgo (Shen et al., 2005), etc. [0003] In recent years, the research on Asr has been in-depth, and there are many research reports on stress. According to literature repo...

Problems solved by technology

However, the preservation, storage and transportation of litchi are difficult, especially the browning of litchi skin after harvesting is serious, which reduces the commodity value of litchi and affects the development of litchi industry.
