Abstract

The invention relates to an application of a CDS (Coding Sequence) sequence of a CBL9 (Calcineurin B-Like) gene of corn. The invention provides the function of the CDS sequence of the CBL9 gene of corn for the first time. The CDS sequence of the CBL9 gene of corn is cloned to a plant expression vector and the vector is transferred to a plant body, so that the obtained transgenetic plant is saline-alkaline tolerant, osmotic stress resistant, high glucose resistant and ABA (Abscisic Acid) stress resistant. ZmCBL9 protein takes part in the salt tolerant and osmotic stress resistant process by regulating the downstream related gene and has important meaning for cultivating high yield transgenetic crops.

Description

technical field

[0001] The invention relates to the field of transgenic plants, in particular to the application of the CDS sequence of the corn CBL9 gene. Background technique

[0002] In nature, plants are different from animals, which cannot escape adversity but can only cope with it. Therefore, plants have evolved a set of fine-tuning mechanisms for sensing adversity stress, transmitting adversity signals, and responding at the molecular, cellular, and physiological levels. Many studies have shown that various stress environments will trigger Ca in plant cells 2+ change in concentration. Ca 2+ The change of concentration in time and space represents a special stress signal, called calcium signal; among them, calcium ion receptor plays a crucial role. To transduce signals and regulate the expression of downstream genes.

[0003] Ca in plants 2+ -Ca 2+ The sensor-actor-target gene is a key regulatory pathway. Many studies have shown that Ca 2+ Sensors can be divid...
