Application of Metagenomics in Plant Diseases Research

doi:10.13560/j.cnki.biotech.bull.1985.2020-0207

Abstract

Abstract:

With the continuous development of sequencing technology,metagenomics has become a current research hotspot and is one of the important approaches of studying plant diseases. Plant disease affects plant normal growth and development,even leads to the death of a plant. Most plant diseases result from pathogenic microorganisms or viruses. In contrast to traditional research methods on microbes,metagenomics can be used to investigate species composition and functional genes in samples by high-throughput sequencing and subsequent bioinformatics analysis,i.e. studying the species diversity. This paper summarizes and compares the analytical strategies of current metagenomics,and its applications in the study of plant rhizosphere microorganisms and plant viruses,and also provides an outlook on future trends,aiming at providing methodological reference in the study of plant diseases.

Key words: metagenomics, high-throughput sequencing, bioinformatics, plant diseases
