Application of plant leaf grinding device for high-throughput rapid DNA extraction

Abstract

The invention relates to an application of a plant leaf grinding device for high-throughput rapid DNA extraction, and belongs to the technical field of biology. The grinding device comprises: a pedestal, a handle, and a plurality of grinding heads and connecting rods, wherein the pedestal is cuboid, is made of a thermal insulation material, and is a device for fixing the connecting rods and the handle; the upper part of the pedestal is connected to the handle; the lower part of the pedestal is connected to the connecting rods; and the lower parts of the connecting rods are connected to the grinding heads. The 96 grinding heads are connected to the base of the pedestal through the 96 connecting rods in an arrangement manner of 8 rows and 12 lines, wherein the transverse distance between two adjacent connecting rods is 0.37-0.9 cm and the longitudinal space distance between two adjacent connecting rods is 0.37-0.9 cm to match a 200 muL 96-hole PCR board and a 96-hole PCR device. For the application of the plant leaf grinding device for high-throughput rapid DNA extraction, whole sample crushing on the 96-hole PCR board can be completed in one step; a requirement of rapid DNA extraction and direct PCR experiment is met; and grinding time is greatly saved and labor requirement is lowered.

Description

1. Technical field [0001] The invention relates to the application of a high-throughput and rapid extraction mill for plant leaf DNA, which belongs to the field of biotechnology. 2. Background technology [0002] With the rapid development of genome projects, the genomes of many plants have been continuously sequenced, such as rice, corn, common wheat, watermelon, tomato, potato, etc. With the completion of genome sequencing, scientists have carried out more extensive and in-depth research on the positioning, cloning and function of important genes. Gene mapping requires a large amount of DNA extracted from plants for PCR amplification. The traditional DNA extraction method is to grind the plant sample into powder by means of a mortar or a mill, and then extract it with a DNA extraction reagent (such as SDS, CTAB, and TPS, etc.) or a DNA extraction kit. The advantage of the traditional method is that high-quality, high-concentration DNA can be extracted. But there are als...
