Summary: We report a new mitovirus, named Puccinia striiformis mitovirus 2 (PsMV2), from the wheat stripe rust fungus. PsMV2 exhibited high multiplication during Pst infection and suppressed programmed cell death triggered by Bax. Silencing of PsMV2 reduced fungal growth and pathogenicity of Pst. Our results indicate that PsMV2 promotes pathogenicity and has a wide distribution in field isolates of Pst.

Summary: The research found that the genetic diversity of wheat stripe rust pathogen in most regions of Yunnan Province is high, but the genetic differences between regions are small, indicating frequent migration of the pathogen within the province. Importantly, Dehong, Dali, Lincang, and Baoshan are likely major sources of wheat stripe rust in Yunnan Province.

Summary: Numerous studies have shown that the actin cytoskeleton responds dynamically to pathogen infection. In this study, researchers investigated the role of the actin-related protein TaARPC5 in wheat's resistance against Puccinia striiformis f. sp. tritici (Pst) infection. They found that TaARPC5 plays a key role in regulating the host's actin cytoskeleton and resistance signaling, contributing to enhanced resistance against Pst.

Summary: The study revealed a significant difference in the number of differentially expressed genes between wheat and barberry when infected by P. striiformis f. sp. tritici, with a higher number of barberry-specifically expressed genes. More evolutionarily conserved genes were observed in barberry-specifically expressed genes, suggesting a longer history of interaction between the fungus and barberry.

Summary: Wheat, a major food crop, is significantly affected by stripe rust fungus. This study investigated the gene and metabolite expression in R88 (resistant) and CY12 (susceptible) during Pst-CYR34 infection. The results showed that Pst infection promotes the synthesis of phenolic compounds, and the key enzyme gene TaPAL contributes to wheat's resistance to Pst. Metabolome analysis also revealed the significant impact of Pst on lignin synthesis. These findings help understand the regulatory networks of wheat-Pst interactions and facilitate durable resistance breeding in wheat.

Summary: This study investigated severity assessment methods for wheat stripe rust based on machine learning. By using image processing techniques, training and testing sets were constructed using segmentation and pixel statistics operations. Unsupervised and supervised learning methods were used to build severity assessment models, with satisfactory performance achieved regardless of considering healthy wheat leaves or not.

Summary: Plant cell walls are composed of polysaccharides with different location and function in different plant types. UDP-Ara mutases (UAMs) play important roles in plant development and stress response. This study investigates the role of UAM3 in wheat during the interaction with stripe rust fungus and treatment with salicylic acid. The results show that silencing or editing of TaUAM3 gene leads to decreased resistance to the fungus and down-regulation of pathogenesis-related genes and reactive oxygen species-generating genes, while the ROS-scavenging gene, TaCAT3, is up-regulated. Therefore, TaUAM3 positively regulates wheat resistance to the fungus.

Summary: Population genetic analyses show that sexual reproduction plays an important role in the evolution of P. striiformis f. sp. tritici races in China, particularly in the emergence of new virulent races affecting wheat cultivars carrying the Yr26 resistance gene. Six candidate genes encoding secreted proteins were identified as potentially related to the virulence on Yr26-carrying wheat cultivars.

Summary: We report a novel narnavirus, PsV5, from the devastating wheat stripe rust fungus. The PsV5 genome contains two predicted ORFs, an RdRp and a reverse-frame ORF with unknown function. Overexpression of PsV5 increases susceptibility to Pst in wheat and enhances virulence in Fusarium graminearum. These findings provide insights for sustainable wheat rust disease control and expand our understanding of virosphere diversity.

Summary: The defense response of wheat against wheat stripe rust and powdery mildew is different. Functional categories, including antioxidant activity and immune system process, exhibited obvious differences between the two infections. TaGSTU6 was found to play an important role in resistance to powdery mildew, and its interaction with TaCBSX3 is crucial for wheat resistance to powdery mildew.
