Ginger stem base rot is the most serious disease that occurs in the main ginger producing areas of China
.
Through years of research, the vegetable disease prevention and control innovation team of the Institute of Plant Protection has identified the pathogen of ginger stem base rot as Pythium myriotylum, and there are differences in the pathogenicity of group rot mold in different regions
, and the research content was published in the journals Plant Disease and Fungal Biology Reviews 。 In order to further reveal the molecular mechanism of group rot mold pathogenesis, the Vegetable Disease Prevention and Control Innovation Team published a paper entitled "Genome of Pythium myriotylum Uncovers an Extensive Arsenal of Virulence-Related Genes among the" in the internationally renowned academic journal Microbiology Spectrum (Impact Factor 9.
043).
Broad-Host-Range Necrotrophic Pythium Plant Pathogens" research paper

.
Through comparative genomic analysis and biological and molecular biology experiments, the paper revealed that there are twice as many exudable protein-coding genes in the genome of the rotting mold of the ginger stem base rot group, including genes for potential effectors, proteases, and cell wall degrading enzymes, and the presence of a large number of tandem repeat sequences in the genome is one
of the key reasons for the enrichment of these toxic genes 。 Pathogenic bacteria significantly upregulate the expression of genes encoding associated proteases, cell wall hydrolases, Nep1-like proteins (NLPs), and elicitin-like proteins during infestation, in which NLPs can induce necrosis in nicotiana benthamiana leaves
.
The relevant results provide a new target for the development of fungicides and provide a theoretical basis
for the prevention and control of stem-based rot of ginger.
