ppcer1-2 gene, carrier and its application in improving the drought resistance of gramineous plants

Abstract

The invention belongs to the technical field of plant breeding, and discloses a PpCER1-2 gene, a carrier and its application in improving the drought resistance of gramineous plants; the sequence of the PpCER1-2 gene is: SEQ ID NO:1. The present invention provides the application of PpCER1-2 gene in improving the drought resistance of gramineous plants; experiments prove that the PpCER1-2 gene has been transferred into and overexpressed Brachypodium distachyon leaves cuticle alkanes increase, and the water loss on the leaf surface slows down , the chlorophyll extraction rate decreased, and the growth of its seedlings in a drought environment also proved that the PpCER1‑2 gene can effectively improve the drought resistance of plants. Grasses are important food crops and garden green space plants. After improving the drought resistance of grasses through the present invention, the amount of irrigation water can be reduced, and at the same time, the problem of crop yield reduction caused by water shortage in summer high temperature weather can be enhanced, which has good application prospect.

Description

technical field [0001] The invention belongs to the technical field of plant breeding, and in particular relates to a PpCER1-2 gene, a carrier and its application in improving the drought resistance of gramineous plants. Background technique [0002] During the growth and development of plants, they are often affected by many abiotic stresses such as drought, salinity, low temperature, etc.; drought stress is one of the most common stress factors in various environmental stresses; improving the drought resistance of plants has become a modern plant breeding It is one of the key problems that need to be solved urgently. During the long-term evolutionary process, higher plants gradually evolved a series of physiological or developmental mechanisms to respond to water stress in the environment. This adaptability of plants involves many fields such as plant morphology, physiology, biochemistry and molecular biology. The tolerance of higher plants to water stress has the same m...

AI Technical Summary

Problems solved by technology

[0004] In summary, the problem in the prior art is that there is still a lack of effective gene resources for improving grass cuticle characteristics, especially the lack of waxy synthetic genes on grass non-model plants, thereby hindering the use of genetic engineering. The application of technology to improve the characteristics of cuticle and improve the drought resistance of plants
