Background
Drought is a major natural disaster faced by people from ancient times, even today with developed agricultural technologies, water stress caused by drought and water shortage is still a major factor for limiting high and stable yield of plants (crops), along with economic development and population growth of people, water resource shortage phenomenon is more and more serious, and the expansion of arid areas and the aggravation of drought degree are directly or indirectly caused, so that drought trend has become a focus of global attention. Especially in northwest regions of China, drought has more serious influence on agricultural production.
Development of water-saving agriculture in arid regions is imperative to realize sustainable development of agriculture in northwest arid regions in China. Besides greatly developing water conservancy facilities and improving the crop growth environment, the method has great significance in culturing new varieties of crops with strong drought resistance. The cultivation of new varieties of drought-resistant crops is mainly realized through two ways of traditional crossbreeding and biotechnology breeding, but the biotechnology breeding has the advantages of strong pertinence, high breeding speed, high breeding efficiency and the like, and is valued and promoted by breeders, but most of crops have poor drought resistance, narrow genetic foundation and development of excellent drought-resistant genes as key limiting factors of drought-resistant breeding success and failure of crops in terms of traditional crops. A large number of drought-tolerant rural wild plants, such as cistanche salsa, broom cypress, ammopiptanthus mongolicus, halogeton, and the like, are distributed in northwest arid regions of China, contain abundant drought-resistant genes, discover the resources of the native drought-resistant genes, and have important value for accelerating the cultivation process of new varieties of drought-resistant crops in China.
The salina (Halogeton glomeratus) belongs to annual herbs of chenopodiaceae, is a drought-resistant and salt-tolerant pioneer plant widely distributed in northwest arid regions of China, has strong drought resistance and salt tolerance, and a salt tolerance mechanism mainly comprises two aspects of isolation of salt vacuole and limiting absorption of root salt, has obvious advantages in the development of drought-resistant and salt-tolerant genes, but has serious lag in research on the development of drought-resistant and salt-tolerant genes in the salina, and needs to be enhanced urgently.
Problems of the prior art: the whole genome of the halogeton has not been published, and the application of the halogeton HgS5 gene and drought resistance thereof is not seen in the prior art.
Disclosure of Invention
In view of the defects of the prior art, the invention provides a halogeton HgS5 gene and application thereof in drought resistance.
In order to achieve the above purpose, the present invention adopts the following technical scheme:
1. the full-length sequence of the halogeton HgS5 gene is shown in a sequence table, and the cDNA coding sequence of the halogeton HgS5 gene is the nucleotide sequence from 298 th to 1407 th positions in SEQ ID NO.1, and the halogeton HgS5 gene comprises 1110bp. The coded amino acid sequence consists of 370 amino acids, as shown in SEQ ID NO.2.
2. The cloning and obtaining method of the halogeton HgS5 gene comprises the following steps: (1) sequence information acquisition; (2) cloning of HgS5 gene; (3) HgS5-pMD19-T transformed E.coli competent cells; (4) screening for bluish white spots and sequencing; (5) the bacterial liquid suitable for sequencing is stored in glycerol.
3. The method for verifying the HgS5 gene function of the salina comprises the following steps: (1) constructing a gene HgS5 overexpression vector; (2) Agrobacterium-mediated transformation and cultivation of Arabidopsis thaliana; (3) identifying the drought resistance of the arabidopsis through HgS5 gene transfer.
4. Application of halogeton HgS5 gene in improving drought resistance of plants.
The beneficial effects are that: the invention provides an HgS5 gene sequence, which is cloned from drought-resistant and salt-tolerant plant salina to a new drought-resistant gene, and further transformed Arabidopsis thaliana is subjected to drought resistance identification, and the result proves that the drought resistance of the Arabidopsis thaliana strain transformed with the HgS5 gene is greatly improved. The molecular weight of the HgS5 is less than 2000bp, the gene is small, the genetic transformation operation is convenient, and the acquisition of the drought-resistant gene HgS5 provides a precious gene resource for the cultivation of drought-resistant crops and new plant varieties.
