The aim of the current study was to investigate the prokaryotic expression of the Magnaporthe oryzae effector genes BAS1 and BAS4 fused to the fluorescent protein mCherry. Based on previous polymorphic analysis of BAS1 and BAS4 in rice blast strains using PCR, blast strains containing the PCR products of BAS1 and BAS4 were selected for liquid culture for total RNA extraction.

Construction of overexpression vectors of Magnaporthe oryzae genes BAS1 and BAS4 fusion to mCherry and screening of overexpression strains

M. L. Liang, Yan, J. L., Yang, Y. Q., Liu, L., Li, C. Y., and Yang, J., Construction of overexpression vectors of Magnaporthe oryzae genes BAS1 and BAS4 fusion to mCherry and screening of overexpression strains, vol. 14, pp. 7068-7078, 2015.

The aim of this study was to construct overexpression vectors and selecting strains of the Magnaporthe oryzae effectors BAS1 and BAS4. Primer pairs of BAS1, BAS4, and mCherry were designed based on their known nucleotide sequences. The coding sequences of BAS1 and BAS4 were amplified, and the pXY201 plasmid was selected as a template to amplify the mCherry sequence. Fragments of BAS1 and mCherry, and BAS4 and mCherry were ligated into the pCAMBIA1302 vector. The recombinant pCAMBIA-BAS1-mCherry and pCAMBIA-BAS4-mCherry plasmids were transformed into E.

Assessment of sensitivity and virulence fitness costs of the AvrPik alleles from Magnaporthe oryzae to isoprothiolane

W. H. Wu, Wang, L., Zhang, S., Liang, Y. Q., Zheng, X. L., Yi, K. X., and He, C. P., Assessment of sensitivity and virulence fitness costs of the AvrPik alleles from Magnaporthe oryzae to isoprothiolane, vol. 13, pp. 9701-9709, 2014.

The in vitro sensitivity of AvrPik allele isolates of Magnaporthe oryzae to isoprothiolane was examined and the virulence fitness costs of AvrPik allele isolates to isoprothiolane were assessed. Isoprothiolane was found to suppress the radial growth of AvrPik allele isolates at all concentrations (1, 5, 10, 15, and 20 μg/mL). Generally, a higher isoprothiolane concentration has a stronger inhibitory effect on mycelial growth in AvrPik allele isolates at 6 and 10 days after inoculation.
