Thinopyrum intermedium ERF-transcription factor and its coding gene and use

Abstract

The invention discloses a middle couch grass ERF transcription factor and its coding gene. The middle couch grass ERF transcription factor can be the protein with one of the following amino acid residues sequences that SEQ ID No: 2 in sequence list; or its amino acid residues sequence which is replaced and / or missed and / or added with one or many amino acid residues, and relevant to plant against disease against reverse performance. The transcription expression of the coding gene is greatly induced by rhizoctonia cerealis, salt, cold, ethylene etc. The TiERF1 of the invention supplies the base for the relevant gene expression, gene resources for gene engineering breeding, and will play an importance role in increasing plant against disease against reverse performance for gene engineering breeding.

Description

technical field

[0001] The present invention relates to a plant ERF transcription factor and its encoding gene and application, in particular to an ERF transcription factor of Echinopsis intermedia and its encoding gene, and the application of the gene in cultivating disease-resistant plants and stress-resistant plants. Background technique

[0002] At present, biotic stress such as various diseases and insect pests, and abiotic adversity stress such as drought, salinity, and low temperature are important factors restricting the production and development of crops, forest grass, and vegetables. For example, with changes in farming systems, fertilizer and water conditions, and climate conditions, the damage caused by soil-borne fungal diseases such as wheat sheath blight and scab and air-borne fungal diseases such as wheat powdery mildew and stripe rust in my country's main wheat producing areas It is becoming more and more serious, ranging from causing a 20-30% reduction in w...
