Abstract

The invention discloses primers, a kit and a detection method for detecting a bean yellow mosaic virus. The sequences of the primers disclosed by the invention are BYMV Primer-1:5'-ccaacattccgccaaataat-3', and BYMV Primer-2:5'-aatacgaacaccaagcatgg-3'; and the kit and the detection method contain a primer BYMV Primer-1 and a BYMV Primer-2. The primers and the detection method for detecting the bean yellow mosaic virus disclosed by the invention are high in accuracy, strong in specificity, and high in sensitivity.

Description

technical field [0001] The invention relates to a primer, a kit and a detection method for RT-PCR detection of bean yellow mosaic virus, belonging to the field of biotechnology. Background technique [0002] Bean yellow mosaic virus can infect a variety of plants such as legumes, Chenopodiaceae, amaranthaceae, and apricots, such as kidney beans, broad beans, cucumbers, tobacco, canna, gladiolus, etc.; the virus belongs to the family Potyviridae (Potyviridae), Potatovirus Y (Potyvirus) members. The length of virus particles is 700-750nmX13nm, the lethal temperature is 50-60°C, the dilution limit is 10-3-10-4, and the in vitro virus preservation period is 3-4 days. The main transmission media are: aphids, non-persistent transmission, which can be transmitted by mechanical inoculation. Bean yellow mosaic virus mainly infects the leaves, the diseased leaves turn yellow and distorted, the flower spikes grow difficult, and the flowers are few and small. [0003] The existing pr...
