BHLH gene influencing salt tolerance of populus sutchuenensis and application of bHLH gene

Abstract

The invention discloses a bHLH gene influencing the salt tolerance of populus sutchuenensis and application thereof.The sequence of the bHLH gene is shown in a sequence table 1, the amino acid sequence of the bHLH gene is shown in a sequence table 2, and the application of the bHLH gene is that knockout expression of the bHLH gene influences the salt tolerance of populus sutchuenensis, so that breeding of salt-tolerant poplar new germplasm is facilitated; research results provide excellent resistance genes for improvement of salt-tolerant varieties of poplars, and have important scientific significance.

Description

technical field [0001] The invention belongs to the technical field of genetic engineering, and in particular relates to a bHLH gene affecting the salt tolerance of Populus japonicus and its application. Background technique [0002] Transcription factors are master regulators of stress-responsive genes and are preferred for plant improvement. However, many transcription factors in different plants remain to be discovered, and among more than 80 families, only a few transcription factors have been studied in depth to have roles in biotic and abiotic stress responses. Basic helix-loop-helix proteins (bHLH) are the most widespread class of transcription factors in eukaryotes, regulating gene expression by recognizing and interacting with specific motifs in target genes; not only universally involved in plant growth and Metabolism, and also play an important role in plant responses to stress. However, most studies on bHLH transcription factors have focused on a small number o...
