Embodiment 1

[0031] In this embodiment, specific primers and Taqman-MGB probes are designed according to the specific site difference (G / A) of the rapeseed canker bacterium Leptosphaeria maculans and its close species ITS (internal transcribed spacer, the transcription spacer region of ribosomal gene) sequence The real-time fluorescent PCR technology was applied to the detection of L.maculans, the stem-base canker of rapeseed, and the experimental steps were as follows:

[0032] 1 Material method

[0033] 1.1 Test strains

[0034] Some strains of rapeseed canker L.maculans and rapeseed blackleg L.biglobosa used in the test were isolated and purified by our laboratory (Shanghai Entry-Exit Inspection and Quarantine Bureau) from imported rapeseed samples from Canada, Australia and Ukraine. Some strains were provided by Shenzhen, Jiangsu, and Ningbo Entry-Exit Inspection and Quarantine Bureau Technology Centers. The domestic rapeseed black shank L.biglobosa strain was provided by Mr. Li Qiang...

Abstract

The invention discloses a real-time fluorescent PCR detection method of L.maculans as well as a primer and a probe used for detection. According to the difference of the sequences of the L.maculans and a similar species of ITS thereof, a primer Lmb3(5'-caccaattggatccccta-3') / R2(5'-ggcgcaaaa tgtgctgcgct-3') and a probe Probe-M(5'-FAM-cacttgggactcgccttg-MGB-3') which are used for detecting the L.maculans are designed, and the real-time fluorescent PCR detection method of the L.maculans is constructed. The sensitivity of the detection method reaches 4pg hypha DNA, the entire detection process is controlled within 4 hours, and the characteristics of high speed, specificity and sensitivity of the invention can meet the quick initial survey of an imported rapeseed sample and the quick identification of a pathogen isolate.

Description

technical field [0001] The invention relates to the technical fields of agriculture and plant quarantine, in particular to a method for detecting rapeseed canker, in particular to a real-time fluorescent PCR detection method for rapeseed canker. In addition, the invention also relates to primers and probes for detecting canker canker of rape. Background technique [0002] Rapeseed black shank (Phoma stem canker), also known as "rape black leg", is one of the most serious fungal diseases of rapeseed worldwide. The pathogen is Phoma stem canker, which mainly includes two species: Phoma stem canker Leptosphaeria biglobosa and Leptosphaeria maculans, two pathogenic bacteria, have similar morphological characteristics, but differ in their ability to cause stem infection and base ulcers in rapeseed. The former has weak pathogenicity and generally causes damage to the middle and upper parts of the stem, causing small losses. It is distributed in some rape-producing countries inclu...
