Summary: This study reveals the role of TaAP2-15 in the resistance of wheat to the stripe rust fungus, showing that it positively regulates the expression levels of pathogenesis-related genes and reactive oxygen species-scavenging genes to affect pathogen growth. Additionally, TaAP2-15 interacts with a zinc finger protein, TaRZFP34, providing new insights into the host-pathogen interaction mechanism.

Summary: This study used LC-MS technology to analyze the metabolomic responses of Pst-resistant and susceptible wheat varieties to P. striiformis infection. The results showed that wheat plants undergo time-dependent metabolic reprogramming in response to the pathogen, with changes in phenylpropanoids, amino acids, lipids, benzoic acids, TCA cycle intermediates, and benzoxazinoids. The resistant cultivar Koonap accumulated defense metabolites more rapidly than the susceptible Gariep cultivar, suggesting the potential for metabolic engineering to improve plant tolerance and resistance to biotic stresses.

Summary: This study identified a wheat RNA-binding protein 1 (TaRBP1) that acts as a negative regulator in response to infection by Puccinia striiformis f. sp. tritici (Pst). Knockdown of TaRBP1 resulted in enhanced resistance to Pst, suggesting its role in plant defence. TaRBP1 interacted with TaGLTP and prevented its degradation in plants. The findings reveal a novel susceptible mechanism by which plants fine-tune their defence responses during Pst infection.

Summary: This study identified 131 chitinase genes in 10 fungal genomes and found 16 chitinase genes from Puccinia striiformis f. sp. tritici (Pst). The expression of PstChia1 was the highest during Pst infection and it showed chitinase enzyme activity. Silencing PstChia1 limited the growth and reduced the virulence of Pst, indicating its role in pathogenicity and interference with plant immunity.

Summary: The TaFIM1 gene in wheat plays a positive regulatory role in pathogen resistance and response to abiotic stress, with silencing TaFIM1 leading to a reduction in resistance against stripe rust. These findings shed new light on the role of fimbrin in wheat.

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: This study cloned and identified a wheat G6DPH gene, TaG6PDH2, which is significantly upregulated in wheat leaves infected with Puccinia striiformis f. sp. tritici (Pst) or treated with abiotic stress factors. Functional analysis revealed that TaG6PDH2 encodes a chloroplast-targeting G6PDH protein. Silencing TaG6PDH2 compromised wheat resistance to Pst avirulent pathotype CYR23, and TaG6PDH2 was found to interact with wheat glutaredoxin TaGrxS4.

Summary: The study assessed the infection risk of barberry by stripe rust and stem rust pathogens in Asia and Southeastern Europe, with different levels of risk identified in different regions. The findings can guide monitoring and rust management programs in these areas, and the modeling framework used in the study may have broader applications in predicting rust infection risk in other regions.

Summary: The obligate biotrophic fungus Puccinia striiformis f. sp. tritici (Pst) employs the effector Hasp98 to inhibit wheat's immune responses and promote the infection of P. striiformis. Hasp98 interacts with the wheat protein TaMAPK4, inhibiting its kinase activity and interfering with the MAPK signaling pathway. This study provides insights into how Pst effectors regulate host defense responses and promote stripe rust disease.
