Natural genomic variation in rice blast genomes is associated with specific heterochromatinmodifications

D. Rowe, J. Huang, W. Zhang, D. Mishra, K. W. Jordan, B. Valent, S. Liu, D. Cook

The paper examines DNA sequence variation in rice blast fungi, finding that heterochromatin-associated histone marks correlate with SNP and INDEL frequency, even after accounting for selection.

A Re-evaluation of phylogenomic data reveals that current understanding in wheat blast population biology and epidemiology is obfuscated by oversights in population sampling

M. L. Farman, J. P. Ascari, M. Rahnama, E. M. Del Ponte, K. F. Pedley, S. Martinez, J. M. C. Fernandes, B. Valent

The paper re-analyzes phylogenomic data to show that previous conclusions about wheat blast population biology and epidemiology are based on incomplete sampling of grass-infecting populations.

Clathrin-mediated Endocytosis Facilitates Internalization of Magnaporthe oryzae Effectors into Rice Cells

E. Oliveira-Garcia, T. M. Tamang, J.-E. Park, M. Dalby, M. Martin-Urdiroz, C. Rodriguez Herrero, A. Hong Vu, S. Park, N. J. Talbot, B. Valent

This study shows that Magnaporthe oryzae uses clathrin-mediated endocytosis to internalize effector proteins into rice cells.

Recombination of standing variation in a multi-hybrid swarm drove adaptive radiation in a fungal pathogen and gave rise to two pandemic plant diseases

M. Rahnama, B. Condon, J. P. Ascari, J. R. Dupuis, E. M. Del Ponte, K. F. Pedley, S. Martinez, B. Valent, M. Farman

The paper shows that recombination of standing variation in a fungal hybrid swarm led to rapid adaptive radiation in Pyricularia oryzae, causing two new plant diseases.

CRISPR-Cas12a induced DNA double-strand breaks are repaired by locus-dependent and error-prone pathways in a fungal pathogen

J. Huang, D. Rowe, W. Zhang, T. Suelter, B. Valent, D. Cook

The paper investigates DNA repair mechanisms after CRISPR-Cas12a-induced double-strand breaks in Magnaporthe oryzae, identifying locus-dependent and error-prone repair pathways leading to various mutation types.

A hierarchical transcriptional network controls appressorium-mediated plant infection by the rice blast fungus Magnaporthe oryzae

M. Oses-Ruiz, M. Martin-Urdiroz, D. M. Soanes, M. J. Kershaw, N. Cruz-Mireles, G. Valdovinos-Ponce, C. Molinari, G. R. Littlejohn, P. Derbyshire, F. Menke, B. Valent, N. J. Talbot

The paper identifies a hierarchical transcriptional network in Magnaporthe oryzae that regulates appressorium development and plant infection.

Gene flow between divergent cereal- and grass-specific lineages of the rice blast fungus Magnaporthe oryzae

P. Gladieux, B. Condon, S. Ravel, D. Soanes, J. L. Nunes Maciel, A. Nhani, L. Chen, R. Terauchi, M.-H. Lebrun, D. Tharreau, T. Mitchell, K. F. Pedley, B. Valent, N. Talbot, M. Farman, E. Fournier

This study uses whole-genome sequencing of 76 Magnaporthe oryzae isolates to analyze population structure and gene flow, revealing multiple divergent lineages and evidence of inter-lineage genetic exchange.
