Abstract

The invention discloses an ultraviolet stress-related gene of highland barley and a cloning method thereof. The gene can be used for detecting whether the highland barley suffers from ultraviolet stress or not. The nucleotide sequence of the ultraviolet stress-related gene of the highland barley provided by the invention is as shown in SEQ ID NO.1. The expression level of the gene is related to whether the highland barley suffers from ultraviolet radiation stress or not, whether the highland barley suffers from ultraviolet radiation stress or not can be judged by detecting the expression level of the gene, theoretical support is provided for the control of subsequent growth conditions of highland barley growth, and the gene has a good market application prospect.

Description

technical field [0001] The invention relates to an ultraviolet stress related gene of barley and application thereof. Background technique [0002] Highland barley English name: hulless barley, is a kind of cereal crops of the Poaceae Barley genus, because the inner and outer glumes are separated and the kernels are exposed, so it is also called naked barley, barley, and rice barley. It is mainly produced in China's Tibet, Qinghai, Sichuan, Yunnan and other places, and is the main food of the Tibetan people. Highland barley has been planted on the Qinghai-Tibet Plateau for about 3,500 years. It has extended from material culture to spiritual culture, forming a highland barley culture with rich connotations and national characteristics on the Qinghai-Tibet Plateau. With a wide range of medicinal and nutritional value, highland barley products such as highland barley noodles, highland barley steamed buns, and highland barley nutritional powder have been launched. [0003] Th...
