TL;DR: Comparison of the two species' genomes reveals a rapid expansion and diversification of many protein families associated with plant infection such as hydrolases, ABC transporters, protein toxins, proteinase inhibitors, and, in particular, a superfamily of 700 proteins with similarity to known oömycete avirulence genes.

TL;DR: It is shown that a pair of sequence motifs, RXLR and dEER, plus surrounding sequences, are both necessary and sufficient to deliver the protein into plant cells and indicates that the >370 RXLR-dEER–containing proteins encoded in the genome sequence of P. sojae are candidate effectors.

TL;DR: It is shown that effectors of another pathogen type, fungi, contain functional variants of the RXLR motif, and that the oomycete and fungal RX LR motifs enable binding to the phospholipid, phosphatidylinositol-3-phosphate (PI3P).

TL;DR: This work shows that the Phytophthora sojae effector protein Avr1b can contribute positively to virulence and can suppress programmed cell death triggered by the mouse BAX protein in yeast, soybean, and Nicotiana benthamiana cells, and supports the hypothesis that these motifs are critical for the functions of the very large number of predicted oomycete effectors that contain them.

TL;DR: The Phytophthora sojae avirulence genes Avr1a and Avr3a are identified and it is demonstrated how each of these Avr genes display copy number variation in different strains of P.Sojae.
