Problems solved by technology

Although sesame has many advantages, the problem of low and unstable yield of sesame has always been a major problem restricting the development of sesame industry
But generally speaking, the root system of sesame is an underdeveloped root system, and the total amount of root system is small, which indirectly affects the increase of sesame yield per plant

Embodiment Construction

[0020] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0021] Usually according to conventional conditions such as those described in Sambrook et al., Molecular Cloning: A Laboratory Manual (New York: Cold Spring Harbor Laboratory Press, 1989), or Draper et al. (Blackwell Scientific Press, 1988), or according to the manufacturer of the reagents used. suggested conditions.

[0022] The method of cloning the gene SiBRB related to the size of the sesame root system described in the present invention is a method commonly used in the art. Extracting plant root RNA is a commonly used molecular biology technique, and there are many mature techniques for extr...

Abstract

The invention describes the application of the sesame protein SiBRB in regulating the development of plant roots. By overexpressing the gene encoding the sesame protein SiBRB in Arabidopsis, it was found that this gene can significantly reduce the total lateral root length and root fresh weight of Arabidopsis plants, and finally reduce the total root system. This shows that the gene is a key gene that limits the growth of plant roots, and has a good application prospect in regulating plant root development and regulating plant root-to-shoot ratio.

Description

technical field [0001] The invention belongs to the field of molecular biology, and in particular relates to the application of sesame protein SiBRB in regulating the development of plant roots. Background technique [0002] Sesamum (Sesamum indicum L.) is one of the important high-quality oil crops in the world. The annual sesame planting area in China is 800,000 hectares, with a total output of about 750,000 tons, ranking first in the world. At the same time, sesame is a typical oil crop planted in summer, which likes temperature and light, and can complete the entire growth period within 3-4 months. Although sesame has many advantages, the low and unstable yield of sesame has always been a major problem restricting the development of sesame industry. The main reason for the limited production of sesame is that it is mainly distributed in developing countries, where it is usually produced by small farmers. Although sesame has a high yield potential, due to the joint acti...
