AI Technical Summary

Technical Problem

Current technologies lack research on key regulatory genes for petiole color differentiation in non-heading Chinese cabbage, making it difficult to meet the industrial needs of targeted breeding.

Method used

The BcRPGE1 gene was cloned and validated. By regulating its expression level, the color differentiation of petioles in non-heading Chinese cabbage was controlled, including silencing or overexpressing the gene to alter chlorophyll accumulation in the petioles, thereby achieving targeted regulation of petiole color.

Benefits of technology

It provides clearly defined target genes for the targeted improvement of petiole color in non-heading Chinese cabbage, significantly shortening the breeding cycle and improving breeding efficiency. It is highly stable and has strong targeting, making it suitable for molecular marker-assisted breeding and gene editing breeding.

Abstract

The invention relates to the technical field of plant genetic engineering and molecular biology, and provides a BcRPGE1 gene for regulating petiole color differentiation of non-heading Chinese cabbage, and the nucleotide sequence of the BcRPGE1 gene is as shown in SEQ ID NO.1. The invention also provides an application of the gene in adjusting the petiole color differentiation of the non-heading Chinese cabbage and a specific method for adjusting the petiole color of the non-heading Chinese cabbage. In addition, the invention further provides application of the method in directional improvement of the petiole color of the non-heading Chinese cabbage and cultivation of non-heading Chinese cabbage varieties with different petiole colors. The BcRPGE1 gene has the advantages that the BcRPGE1 is determined as a key gene for regulating and controlling the petiole color differentiation of the non-heading Chinese cabbage for the first time, the directional regulation and control of the petiole color can be realized by regulating and controlling the gene, and a new gene resource and a technical support are provided for molecular regulation and control and breeding application of the petiole color of the non-heading Chinese cabbage.
