TL;DR: It is proposed that Slp1 sequesters chitin oligosaccharides to prevent PAMP-triggered immunity in rice, thereby facilitating rapid spread of the fungus within host tissue.

TL;DR: This large-scale study found significantly more presence/absence polymorphisms than nucleotide polymorphisms among 1032 putative secreted protein genes in M. oryzae isolates, corresponding to five previously known AVR genes, whose products are recognized inside rice cells possessing the cognate R genes.

TL;DR: It is reported that the rice blast fungus Magnaporthe oryzae possesses two distinct secretion systems to target effectors during plant infection, and it is concluded that the blast fungus has evolved distinct secretion Systems to facilitate tissue invasion.

TL;DR: An additional complementation study revealed that the two NBS-LRR-type R genes, SasR GA4 and SasRGA5, that are located next to each other and oriented in the opposite direction are necessary for Pia function.

TL;DR: By applying SuperSAGE to Magnaporthe grisea (blast)-infected rice leaves, gene expression profiles of both the rice host and blast fungus were simultaneously monitored by making use of the fully sequenced genomes of both organisms, revealing that the hydrophobin gene is the most actively transcribed M.grisea gene in blast- infected rice leaves.
