Wang S., Li G.R., Chen Y.S., and Huang F.L., 2020, Cloning, expression and purification of MGG_14095 gene of Magnaporthe grisea, 11(1): 1-8 (doi: 10.5376/rgg.2020.11.0001)

Magnaporthe grisea is the most harmful pathogen in the world for rice and the main model organism for elucidating the molecular basis of plant fungal disease interaction. Carrying out relevant research of the growth and development of Magnaporthe grisea has a great significance for the control of Magnaporthe grisea. MGG_14095 gene is the pathogenic gene of Magnaporthe grisea. The bioinformatics prediction of MGG_14095 protein showed that the isoelectric point (PI) of MGG_14095 protein was 5.72, and the instability index was 50.99, belonging to the acid unstable protein and the α/β hydrolase superfamily, containing the keratinase conservative domain; having obvious transmembrane structure and signal peptide cutting site, belonging to the secretory protein. In this study, the MGG_14095 (38~281) gene of Magnaporthe grisea was cloned, and the prokaryotic expression system pETM20-MGG_14095 (38~28) was constructed. We use the stepwise chromatography to purify MGG_14095 protein, and the high-purity soluble target protein was obtained successfully. The results provided for the analysis of MGG_14095(38~281) protein structure, the exploration of pathogenetic mechanism of Magnaporthe grisea and the control of Magnaporthe grisea Certain theoretical and experimental basis.
