Standard gene for molecular identification of pterocarpus santalinus and molecular identification method

Abstract

Pterocarpus santalinus is also called dalbergia odorifera and is a papilionaceae dalbergia plant. Due to the good quality, small distribution area, long maturing period and small existing resource quantity, the market price keeps rising. Under the motivation of huge benefit, the counterfeits of pterocarpus santalinus spread unchecked, and how to accurately identify pterocarpus santalinus becomes the most challenge in the pterocarpus santalinus trading market. The invention provides a standard gene for molecular identification of pterocarpus santalinus and a molecular identification method; and by adopting the method to identify pterocarpus santalinus, the method has the characteristics of quickness, accuracy, low sample damage and the like.

Description

technical field [0001] The invention belongs to the field of molecular biology, and in particular relates to a standard gene for plant molecular identification and a molecular identification method. Background technique [0002] Hainan Huanghuali ( Dalbergia dorifera T.Chen), also known as Dalbergia Dalbergia, is a plant of the genus Dalbergia in the family Papilionaceae, native to the low-altitude plains and hilly areas of Hainan Island in my country. Because of its solid wood, beautiful patterns and fragrance, huanghuali wood, rosewood, chicken wing wood, and iron wood are also known as the four famous woods in ancient China, and it is one of the two mahogany tree species natively produced in my country. Because the material is hard, beautiful and has a fragrance, it has always been regarded as a high-grade wood. Because of the narrow distribution area and excessive felling, the existing number is very small, and it is listed as a national second-class protected plant. ...
