Summary: Research findings indicate that the population of P. sojae, the pathogen causing soybean root and stem rot in Brazil, exhibits high variability, with complex interactions between pathotypes and resistance genes. These findings are important for developing resistant soybean cultivars.

Summary: In this study, we identified a wall-associated protein kinase gene GmWAK1 in soybean that plays a crucial role in soybean resistance to the destructive pathogen Phytophthora sojae. Overexpression of GmWAK1 significantly improved soybean resistance to P. sojae and increased the expression of related genes involved in stress responses. Furthermore, we discovered an interaction between GmWAK1 and the annexin-like protein GmANNRJ4, which enhanced soybean resistance to P. sojae.

Summary: This study used high-throughput sequencing and deep learning to investigate the molecular features in soybean following infection by Phytophthora sojae. Two defense-related transcription factors were selected and their DNA binding sites were predicted using DNA Affinity Purification and sequencing data. A gene regulatory network was constructed, revealing the immune response of soybean against P. sojae.

Summary: The variable genomic region in Tosan-231 containing two Harosoy-derived loci related to Rps7 and one Nemashirazu-derived locus confers broad-spectrum resistance to Phytophthora sojae. Mapping analysis and PCR testing have identified the presence of these resistance loci in Tosan-231.

Summary: This study successfully cloned the resistant gene RpsYD29 from the soybean cultivar Yudou 29 and identified its functional mechanism as regulating the expression of superoxide dismutase 1 (SOD1) to resist Phytophthora sojae. This finding is of great significance for soybean breeding for disease resistance.

Summary: This study analyzed the expression profiles of soybean miRNAs before and after infection with Phytophthora sojae and identified miRNAs related to resistance and susceptibility. Potential target genes of these differentially expressed miRNAs were predicted. The findings contribute to understanding the disease resistance mechanism in soybean.

Summary: PsAvh113 effector plays a crucial role in inducing Phytophthora root and stem rot (PRSR) in soybean. It interacts with soybean transcription factor GmDPB, leading to its degradation and suppression of the downstream gene GmCAT1, thus enhancing plant susceptibility to Phytophthora.

Summary: A new P. sojae resistance QTL with a relatively major effect was identified in this study, spanning a region of about 500 kb on chromosome 15. Plants carrying the favorable allele at this QTL showed a 60% increase in resistance. This offers new opportunities for developing improved soybean cultivars with broad resistance to P. sojae through marker-assisted selection.

Summary: This study investigated the molecular basis of quantitative disease resistance in the soybean-Phytophthora sojae pathosystem using a systems genomics approach. It found that there was significant transcriptional reprogramming in response to P. sojae infection. Through gene co-expression network analysis and eQTL mapping, the genes regulating transcriptional changes and the molecular mechanisms contributing to resistance were identified.

Summary: This study reveals that the GmMKK4-GmMPK6-GmERF113 cascade triggers resistance to P. sojae in soybean, enhancing the soybean's ability to resist diseases. GmMKK4 activates GmMPK6, which then phosphorylates GmERF113, increasing its stability and transcriptional activity.

Summary: The 26S proteasome regulatory subunit GmPSMD interacts with GmPIB1 and plays a significant role in improving soybean resistance to Phytophthora sojae by enhancing the activity of antioxidant enzymes such as POD, SOD, GPX, and CAT to reduce ROS production. This study reveals a valuable mechanism for regulating the pathogen response in soybean.

Summary: This study evaluated the metabolic and transcriptional responses to the expression of AtWRI1 and AtDGAT1 in soybean seeds. The results showed that the expression of these genes did not increase the total fatty acid content, but led to changes in the oil and carbohydrate composition. Transcriptomic analysis revealed down-regulation of oil body packaging protein genes and strong induction of lipase and FA biosynthesis inhibitor genes.

Summary: This study investigated the resistance mechanisms of common bean (a nonhost) and soybean (a host) against Phytophthora sojae, the pathogen causing root and stem rot in soybean. The results showed that common bean exhibited stronger resistance, potentially due to higher levels of phaseollidin, increased cell wall depositions, and callose accumulation.
