AI Technical Summary

Technical Problem

How to regulate plant salt tolerance and root length, especially rice.

Method used

By regulating the expression or activity of the gene encoding OsPL3 protein, the content of OsPL3 protein in plants is increased or decreased, thereby affecting the plant's salt tolerance and root length.

Benefits of technology

By upregulating the expression or activity of OsPL3 protein, the salt tolerance and root length of rice are improved, or by downregulating its expression or activity, the salt tolerance and root length of rice are reduced.

Abstract

The invention discloses application of OsPL3 protein in regulation and control of salt tolerance and root length of rice. The invention belongs to the technical field of biology, and particularly relates to application of OsPL3 protein to regulation and control of salt tolerance and root length of rice. The protein provided by the invention can positively regulate and control the salt tolerance and root length of rice, through the expression quantity of the overexpressed OsPL3 protein, after salt stress treatment, the survival rate of seedlings of the obtained overexpressed plant OsPL3-OE is obviously increased by about one time compared with that of a wild type, the root length development of the OsPL3-OE is also obviously longer than that of the wild type, and the protein has a certain application prospect for rice breeding.
