Transcriptional Programming and Functional Interactions within the Phytophthora sojae RXLR Effector Repertoire[C][W][OA]
TLDR
A broad functional survey of a large sample of candidate RXLR effectors in the oomycete pathogen of soybean found the most strongly expressed immediate-early effectors could suppress the cell death triggered by several early effectors, and most early effectORS could suppress INF1-triggered cell death, suggesting the two classes of effectors may target different functional branches of the defense response.

The bZIP Transcription Factor MoAP1 Mediates the Oxidative Stress Response and Is Critical for Pathogenicity of the Rice Blast Fungus Magnaporthe oryzae
TLDR
It is found that MoAP1 is highly expressed in conidia and during invasive hyphal growth, and regulates transcriptions of M. oryzae that are important in the growth, development, and pathogenicity of the fungus. Expand
Oomycete pathogens encode RNA silencing suppressors
TLDR
This work shows that two effectors from the oomycete plant pathogen Phytophthora sojae suppress RNA silencing in plants by inhibiting the biogenesis of small RNAs, identifying RNA silence suppression as a common strategy used by pathogens across kingdoms to cause disease. Expand
Two Host Cytoplasmic Effectors Are Required for Pathogenesis of Phytophthora sojae by Suppression of Host Defenses1[W][OA]
TLDR
A role for CRN effectors in the suppression of host defense responses is suggested in P. sojae stable transformants, which lose the ability to suppress host cell death and callose deposition on inoculated plants. Expand
The Phytophthora sojae Avirulence Locus Avr3c Encodes a Multi-Copy RXLR Effector with Sequence Polymorphisms among Pathogen Strains
TLDR
The P. sojae Avr3c gene is identified and it is shown that it encodes a predicted RXLR effector protein of 220 amino acids, illustrating the importance of segmental duplications and RX LR effector evolution in the control of race-cultivar compatibility in the P.Sojae and soybean interaction. Expand
A paralogous decoy protects Phytophthora sojae apoplastic effector PsXEG1 from a host inhibitor
TLDR
It is shown that soybean produces an apoplastic glucanase inhibitor protein, GmGIP1, that binds to PsXEG1 to block its contribution to virulence, and may be widely used in Phytophthora pathosystems. Expand
The NLP toxin family in Phytophthora sojae includes rapidly evolving groups that lack necrosis-inducing activity.
TLDR
This study indicates that expansion and pseudogenization of the P. sojae NLP family results from an ongoing birth-and-death process, and that varying patterns of expression, necrosis-inducing activity, and positive selection suggest that NLP have diversified in function. Expand
Phytophthora sojae Avirulence Effector Avr3b is a Secreted NADH and ADP-ribose Pyrophosphorylase that Modulates Plant Immunity
TLDR
Bioinformatics and genetics are combined to identify Avr3b, a new Avr gene from Phytophthora sojae, an oomycete pathogen that causes soybean root rot, and biochemical assays confirmed that AvR3b is an ADP-ribose/NADH pyrophosphorylase, as predicted from the Nudix motif. Expand
Phytophthora suppressor of RNA silencing 2 is a conserved RxLR effector that promotes infection in soybean and Arabidopsis thaliana.
TLDR
It is reported that the P. sojae PSR2 (PsPSR2) belongs to a conserved and widespread effector family in Phytophthora, and experiments provide strong evidence that PsR2 is a Conserved Phytophile effectorfamily that performs important virulence functions specifically during Phytphthora infection of various plant hosts. Expand
The RxLR effector Avh241 from Phytophthora sojae requires plasma membrane localization to induce plant cell death.
TLDR
This work suggests that Avh241 interacts with the plant immune system via at least two different mechanisms, one recognized by plants dependent on subcellular localization and one promoting infection independent on membrane localization. Expand
