Characterization of soybean GmPUB1 proteins that interact with the Phytophthora sojae effector Avr1b protein
Phytophthora sojae is an oomycete which causes stem and root rot disease in soybean. Upon infection, P. sojae could deliver a series of virulent effector proteins into host cell to promote disease on susceptible plants (Tyler et al. 2008, Göhre and Robatzek 2008). Avr1b is one such protein (Tyler et al. 2008). In this report, a soybean U-box protein, GmPUB1-1, was isolated by interaction with P...
متن کاملGmWRKY31 and GmHDL56 Enhances Resistance to Phytophthora sojae by Regulating Defense-Related Gene Expression in Soybean
Phytophthora root and stem rot of soybean [Glycine max (L.) Merr.] caused by the oomycete Phytophthora sojae, is a destructive disease worldwide. The molecular mechanism of the soybean response to P. sojae is largely unclear. We report a novel WRKY transcription factor (TF) in soybean, GmWRKY31, in the host response to P. sojae. Overexpression and RNA interference analysis demonstrated that GmW...
متن کاملStrain Specific Factors Control Effector Gene Silencing in Phytophthora sojae
The Phytophthora sojae avirulence gene Avr3a encodes an effector that is capable of triggering immunity on soybean plants carrying the resistance gene Rps3a. P. sojae strains that express Avr3a are avirulent to Rps3a plants, while strains that do not are virulent. To study the inheritance of Avr3a expression and virulence towards Rps3a, genetic crosses and self-fertilizations were performed. A ...
متن کاملPhytophthora sojae Effector PsCRN70 Suppresses Plant Defenses in Nicotiana benthamiana
Phytophthora sojae, an oomycete pathogen, produces a large number of effector proteins that enter into host cells. The Crinklers (Crinkling and Necrosis, CRN) are cytoplasmic effectors that are conserved in oomycete pathogens and their encoding genes are highly expressed at the infective stages in P. sojae. However, their roles in pathogenesis are largely unknown. Here, we functionally characte...
متن کاملSequence Variants of the Phytophthora sojae RXLR Effector Avr3a/5 Are Differentially Recognized by Rps3a and Rps5 in Soybean
The perception of Phytophthora sojae avirulence (Avr) gene products by corresponding soybean resistance (Rps) gene products causes effector triggered immunity. Past studies have shown that the Avr3a and Avr5 genes of P. sojae are genetically linked, and the Avr3a gene encoding a secreted RXLR effector protein was recently identified. We now provide evidence that Avr3a and Avr5 are allelic. Gene...
