Abstract

The invention discloses a kit and an extraction method for extracting total DNA from the midrib of citrus leaves based on a magnetic bead method. The kit includes lysate, binding solution, washing solution 1, washing solution 2, eluent and magnetic bead suspension; adopt the DNA extraction kit of the present invention to extract the total genomic DNA of citrus leaves, the extracted DNA concentration and The overall level of purity is better than the commercially available Sangon Dzup (Plant) Genomic DNA Rapid Extraction Kit and Tiangen Plant DNA Extraction Kit. The invention is a DNA extraction magnetic bead method kit and an extraction method for the detection of citrus huanglongbing. The kit and the extraction method are applicable to all citrus varieties and have broad spectrum.

Description

technical field [0001] The invention relates to the technical field of analytical biology, in particular to a kit for extracting total DNA from midribs of citrus leaves based on a magnetic bead method and an extraction method thereof. Background technique [0002] Citrus huanglongbing is a devastating disease of citrus, which has caused huge losses to the world's citrus industry. So far, the prevention and control of citrus Huanglongbing at home and abroad mainly relies on the main measures such as eliminating vectors, strengthening quarantine, cultivating disease-free seedlings, and digging up diseased trees. The prevention and control measures of citrus huanglongbing need the help of precise diagnosis technology for citrus huanglongbing. PCR detection of huanglongbing pathogen "Candidatus Liberibacter spp." is currently a reliable method for the diagnosis of citrus huanglongbing, which has the advantages of rapidity, specificity, efficiency and sensitivity. [0003] At pr...
