Abstract

The invention relates to a plant aging specific promoter and application thereof. In the invention, a promoter capable of responding to plant aging signals and regulating high expression of target gene specificity is separated for the first time. The promoter is very useful for regulating the expression of the target gene in a plant aging process, so as to change the plant characters, state and aging process.

Description

technical field

[0001] The invention belongs to the field of biotechnology; more specifically, the invention relates to a plant senescence specific promoter and application thereof. Background technique

[0002] Promoter refers to a DNA sequence in a gene that can accurately and effectively initiate gene transcription, usually located upstream of the gene. Promoter is an important element in the regulation of gene expression. It interacts with trans-acting factors (transcription factors) such as RNA polymerase and other protein cofactors to regulate the level of gene transcription and the specificity of its temporal and spatial expression.

[0003] The most widely used constitutive promoter is the tobacco mosaic virus (CaMV) 35S promoter. At the same time, people attach great importance to cloning constitutive promoters from plants themselves and have achieved initial success. The promoters of genes such as actin (Actin) and ubiquitin (Ubiquitin) have been cloned. Mariani ...
