Abstract
The invention relates to an FvSnRK2.1 gene of Fraxinus velutina Torr salt tolerance and application thereof. The nucleotide sequence of the FvSnRK2.1 gene of Fraxinus velutina Torr salt tolerance is disclosed as SEQ ID NO.1, and the amino acid sequence of the coded polypeptide is disclosed as SEQ ID NO.2. The FvSnRK2.1 gene capable of regulating Fraxinus velutina Torr salt tolerance is cloned from Fraxinus velutina Torr, and the expression of the gene is influenced by salt stress. The FvSnRK2.1 gene integrally enhances the salt tolerance of the plant, enhances the stability, and can have huge application prospects. The FvSnRK2.1 gene has huge potential application value for improving salt tolerance of plants on the basis of gene engineering, thereby providing fundamental basis for researching the whole plant stress-tolerant gene regulation network and stress response reaction mechanism.
Description
technical field [0001] The invention relates to the salt-tolerant FvSnRK2.1 gene of white wax tomentosa and its application, and belongs to the technical field of genetic engineering. Background technique [0002] High-salt stress is the main environmental factor limiting the geographical distribution of plants and crops, and it is also one of the most important abiotic stresses affecting crop yield. High-salt stress can affect the growth and development of plants. In addition, it can also promote the generation of excessive ROS and secondary metabolites in plants, causing oxidative stress and other poisons to plant cells. During the long-term evolution, plants have gradually formed a series of biological mechanisms in response to stress, among which the plant hormone abscisic acid (ABA) plays an important role. In recent years, there have been more and more studies on the molecular mechanism of ABA signal transduction, among which the most prominent progress is the discove...
