Abstract

The invention discloses a preparation method of a hybridization probe and a gene chip for PPV (plum pox virus) major strains. The probe comprises PPV-D, PPV-M, PPV-EA, PPV-Rec, PPV-W and PPV-C. The preparation method of a gene chip is characterized by comprising the following steps: gene chip spotting, PCR amplification and sample marking, chip pretreatment, chip hybridization, chip cleaning, chip scanning analysis and data treatment and result judgment. The invention aims at overcoming the shortcomings of the prior art and providing a hybridization probe for detecting the PPV major strains; and the invention also relates to a preparation method of a gene chip comprising the probe.

Description

technical field [0001] The present invention relates to a hybridization probe for the main strains of plum pox virus, the invention also relates to a method for preparing a gene chip comprising the probe, and the invention also relates to a method for detecting plum pox virus by using the above gene chip , belonging to the field of biotechnology. Background technique [0002] Plumpoxvirus, PPV is an entry plant quarantine pest promulgated by my country in 2007. It is one of the most dangerous viruses for stone fruit trees. It belongs to the genus Potyvirus in the family Potyviridae, and its natural hosts are mainly It is a woody plant of the genus Prunus. After infecting drupe fruit trees such as plums, apricots, peaches, and cherries, the leaves and fruits are seriously damaged, and a large number of immature fruits fall off, resulting in a decline in fruit quality and yield. The long-distance spread of the virus mainly depends on the transfer of plant propagation materials...
