Plant stress resistance related protein as well as coding gene and application thereof

Abstract

The invention discloses a protein which is named as OsMSr2 and is from rice. The protein is (1) a protein formed from an amino acid sequence shown by the sequence 2 in a sequence table or (2) a plant stress resistance related protein derived from the protein (1) by replacing and / or deleting and / or adding one or more than one amino acid from the amino acid sequence shown by the sequence 2 in the sequence table. Introducing the coding gene OsMsr2 of the protein into a plant can increase the germination rate of seeds under adverse conditions, increase root length and root weight, increase the growth potential of the plant, ensure seeds are enlarged, increase the net photosynthetic rate of leaves and increase the tolerance of the plant under adverse conditions.

Description

technical field

[0001] The invention relates to the field of biotechnology, in particular to a protein related to plant stress tolerance and its coding gene and application. Background technique

[0002] Drought, low temperature, and high temperature are common adversity factors affecting crop growth and development, which largely limit crop yield and geographical distribution. In order to improve the yield of crops under stress and break the geographical distribution restrictions, it is an effective way to find new stress-tolerant genes and use genetic engineering to improve crop stress tolerance. Traditional methods are limited due to the complexity of plant stress regulation mechanisms and the lack of effective screening techniques. Studies have shown that most genomes in plants are involved in their own responses to stress factors such as drought and high salinity, and changing the expression of a single gene can significantly improve the ability of plants to resist dro...
