Abstract

The invention relates to the technical field of biological detection, in particular to fluorescent quantitative PCR primers and kit for detecting a potato leaf virus. The fluorescent quantitative PCRprimers include primers Actin-F and Actin-R for amplifying reference genes and primers PLRV2-F and PLRV2-R for amplifying PLRV genes. The kit comprises the above primers. The primers and the kit can detect at the molecular level that the potato leaf virus exists in potato plants, the virus gene expression situation can be quantitatively analyzed, and the fluorescent quantitative PCR primers have the advantages of high efficiency, strong specificity, good accuracy and repeatability, high sensitivity, high detection speed, low material consumption, low cost, quantitative detection and the like.

Description

technical field [0001] The invention relates to the technical field of biological detection, in particular to a fluorescent quantitative PCR primer and a kit for detecting potato leafroll virus. Background technique [0002] Potato leafroll virus (PLRV) is classified as Luteovirus group (Luteovirus), is a member of the genus PLRV, and is one of the most important viruses in potato virus diseases that endanger potato production. The PLRV virion is spherical, equiaxed, and 24nm in diameter. It is a positive-strand RNA virus without poly A at the 3' end and a strictly conserved sequence of 5-20 bp at the 5' end. The virus is transmitted in seed potatoes, and is transmitted by aphids in a persistent manner in the field. It cannot be transmitted mechanically. The vascular bundle of the host plant is its main distribution site. The content of the virus in the host body is low, and it is difficult to purify in large quantities, so that people cannot conduct thorough molecular biol...
