Abstract

The invention provides a specific expression promoter OsAnth1 for anthers and an application thereof. The promoter which can carry out a specific expression in the plant anthers is departed, and the promoter can guide a target gene to carry out a specific high expression in the plant anthers and carry out a low expression or not express in other issues of a plant. The invention further provides an expression box containing the promoter, a plant expression carrier and a method for obtaining corresponding host bacteria and converters by using the promoter. In addition, the promoter is applied to plant gene engineering. The promoter has a significant theory and an actual meaning for relevant researches about the rice anthers. The wide application and the wide market prospect are going to be obtained in the field of agriculture.

Description

technical field [0001] The invention relates to the technical fields of biotechnology and plant genetic engineering. Specifically, the present invention relates to a rice anther-specific expression promoter OsAnth1 and its application. The promoter can drive the specific expression of a target gene in rice anthers in a rice transgene regulation system. Background technique [0002] The exogenous DNA sequence is linked to a specific promoter to promote expression in the plant host, and the choice of the promoter type determines the time and location of gene expression. Plant gene regulation is mainly carried out at the transcriptional level, which is coordinated by a variety of cis-acting elements and trans-acting factors. The promoter is an important cis-acting element. It is a DNA sequence located in the upstream region of the 5' end of the structural gene to regulate gene transcription. It can activate RNA polymerase to accurately combine with the template DNA to ensure a...
