Racomitrium canescens protein phosphatase 2C gene RcPP2C as well as encoded protein and application thereof

Abstract

The invention relates to a racomitrium canescens protein phosphatase 2C gene RcPP2C as well as encoded protein and an application thereof. The invention aims at providing the racomitrium canescens protein phosphatase 2C gene RcPP2C as well as the encoded protein and the application thereof. The sequence of the racomitrium canescens protein phosphatase 2C gene RcPP2C is shown as SEQ ID No: 1 in a sequence list, and an amino acid sequence is shown as SEQ ID No.2 in the sequence list; and the gene is applied to the improvement of plant drought resistance. The RcPP2C gene is related to drought resistance in a cell signal transduction pathway; the gene, when transformed into a plant, can improve the drought resistance of the plant and the gene can lay a foundation for breeding a novel drought-resistant plant variety and enhancing the drought resistance of the plant; therefore, the gene has important significance. The gene provided by the invention is applied to the field of molecular breeding.

Description

technical field

[0001] The invention relates to a gene, its encoded protein and its application, in particular to the moss protein phosphatase 2C gene RcPP2C, its encoded protein and its application. Background technique

[0002] Water stress such as drought, high salinity and low temperature is the most important environmental stress factor affecting plant growth and development. Water scarcity has become a major handicap to agricultural development worldwide. In order to solve this problem, people are trying to find drought-tolerant genes from resource-rich wild plant gene pools, and use advanced biotechnology to breed new plant varieties that are resistant to salt, drought, and low temperature, and enhance the stress resistance of plants, thereby Increase economic value. Therefore, how to improve the stress resistance of plants has become a research hotspot for scientists from all over the world.
