Summary: Bacteria have developed sophisticated iron transport and regulation systems to overcome iron deficiency. The binding of iron carriers to the cell surface initiates gene transcription, providing the bacteria with the necessary iron. This process involves signal recognition and signal transmission into the cytoplasm.

Summary: In this study, two phages were isolated from market-bought pepper fruit and characterized. One of the phages was found to significantly inhibit the propagation of Pseudomonas syringae pv. tomato in plant tissues. This research contributes to the understanding of phage-host interactions in different plant systems and suggests the potential use of this phage as a biocontrol agent.

Summary: This study reports the first identification of Pseudomonas syringae strains infecting zucchini in Australia, causing significant yield losses. The isolates exhibited variations in pathogenicity across different plant species and some produced fluorescent pigment. Additionally, it was discovered that different zucchini varieties showed varying levels of susceptibility to the isolates.

Summary: This study analyzed the draft genome sequences of two pathogenic strains of Pseudomonas syringae pv. aptata to evaluate their survival strategies and pathogenic potential. The results showed differences in genome size, GC content, and protein-coding sequences between the two strains. Furthermore, differences in effector sequences were found to be related to the type III secretion system. This study provides important information on the genomic features, epidemiology, and pathogenic strategies of P. syringae pv. aptata.

Summary: Extracytoplasmic function (ECF) sigma factors are subunits of RNA polymerase specialized in activating the transcription of genes responding to specific environmental conditions. They can be activated by diverse signal-transduction pathways, with the most common mechanism involving a membrane-bound anti-sigma factor. However, there are many ECF sigma factors that exhibit non-canonical regulatory mechanisms.

Summary: A total of 293 bacterial strains were isolated from the surface and internal tissues of almond and apricot trees in East Azerbaijan province, Iran. These strains belong to 15 different genera, with Pseudomonas, Pantoea, and Lysinibacillus being the most abundant. Some strains showed antagonistic activity against the causal agent of apricot canker disease.

Summary: This study analyzed the differences in resistance to the pathogen Pseudomonas syringae pv. tomato (Pst) between Arabidopsis thaliana accessions Col-0 and C24, and found that the resistance differences mainly involve salicylic-acid-dependent systemic acquired resistance mechanisms and differential activity of certain metabolic pathways.

Summary: By analyzing the transcriptomic profiles of kiwifruit shoots, it was found that different varieties have different defense mechanisms against Pseudomonas syringae pv. actinidiae (Psa). The PTI and cell walls play important roles in Maohua's defense against Psa infection, while the ETI is crucial in Hongyang's defense against the pathogen.

Summary: This study investigated the genetic characteristics of Pseudomonas syringae pv. actinidiae population from kiwifruit in Sichuan, China. The isolates were characterized using morphological features, multiplex-PCR, and multilocus sequence analysis (MLSA). The study revealed rich genetic diversity in P. syringae pv. actinidiae isolates from Sichuan.

Summary: This study sequenced the complete genome of Pseudomonas syringae pv. tomato strain DAPP-PG 215, which was described as a race 0 strain. The analysis revealed that although the strain is phylogenetically related to race 1 strains, it has a race 1 genetic background but harbors a complete ortholog of the avrPto1 gene.

Summary: In the search for antibacterial agents against Pseudomonas syringae pv. actinidiae (Psa) from kiwi-associated fungi, two pairs of epimeric cytochalasins, zopfiellasins A-D, were identified from the fungus Zopfiella sp. Compounds 1 and 3 showed antibacterial activity against Psa, marking the first report of cytochalasin derivatives with anti-Psa activity.

Summary: In this study, ten strains of Kiwifruit bacterial canker were isolated and sequenced, revealing divergences in pathogenicity and pathogenic-related genes among the strains. Pseudomonas syringae pv. actinidiae infection re-programmed the expression of host genes, with down-regulation of genes involved in plant-pathogen interactions, especially calcium signaling transduction and fatty acid elongation. These findings provide insights into understanding the molecular mechanism of Psa-kiwifruit interactions and improving resistance in the kiwifruit crop.

Summary: Continued surveillance and risk assessment of emerging SARS-CoV-2 variants are crucial in pandemic response. The study found that the Delta variant showed enhanced transmissibility compared to other strains. Prior infection with SARS-CoV-2 provided varied levels of protection against reinfection.

Summary: This study demonstrates that both Influenza A virus (IAV) and SARS-CoV-2 can establish productive infections and shed detectable aerosolized virus from the ocular exposure, contributing to onward transmission of these viruses. The ocular surface represents a susceptible mucosal surface that can be infected and transmit the virus similarly to respiratory exposure.
