Gene expression changes of Pseudomonas syringae pv. actinidiae biovar 6 in various culture conditions

Project description:Pseudomonas syringae pv. actinidiae biovar 6 (Psa6) is a causal agent of kiwifruit bacterial canker and is a unique plant pathogenic bacterium, producing two types of phytotoxins, coronatine and phaseolotoxin. We investigated the expression behavior of virulent genes of Psa6 under various culture conditions.

Whole-transcriptome microarray analysis of different biovars of Pseudomonas syringae pv. actinidiae grown in rich medium or apoplast-like conditions

Project description:Purpose: Pseudomonas syringae pv. actinidiae (Psa) is a phytopathogen that causes devastating bacterial canker in kiwifruit. Among five biovars defined by genetic, biochemical and virulence traits, Psa3 is the most aggressive and is responsible for the most recent reported outbreaks, but the molecular basis of its heightened virulence is unclear. A custom P. syringae multi-strain whole-genome microarray platform, encompassing biovars Psa1, Psa2 and Psa3 and the well-established model P. syringae pv. tomato, was used to analyse early bacterial responses to an apoplast-like minimal medium. Conlusion: this work highlighted that diverse early responses to the host apoplast, even among bacteria belonging to the same pathovar, can lead to different virulence strategies and may explain the differing outcomes of infections.

Gene regulatory networks of kiwifruit response to Pseudomonas syringae pv. actinidiae

Project description:To study the responses of kiwifruit to Pseudomonas syringae pv. actinidiae, one-year-old potted seeding A. c. var. deliciosa cultivar ‘Jinkui’ and the pandemic Pseudomonas syringae pv. actinidiae bacterial strain JF8 (CCTCC AB2018305) were used for this study. This bacterial strain was originally isolated from A. c. var. chinensis cultivar ‘Jinfeng’ and further characterized . Plants were maintained in an aseptic room, with 95% of relative humidity, have natural light and no further fertilization after their receiving from the nursery. For inoculation, the P. s.pv. actinidiae strain was streaked on nutrient-sucrose agar (NSA) and incubated at 25 °C for 48-h. Ten microliters of a bacterial suspension (1-2×107cfu/mL) prepared in sterile 0.85 % w NaCl were inoculated in the plants chosen for investigation. The bacterial suspension was sprayed to entirety tree. In parallel, control plants were treated in the same way with sterile 0.85 % w NaCl solution. The inoculated and control plants were randomly distributed in the room at 15 ± 3 °C. 24-h after inoculation, ‘Jinkui’ leaves were sampled from the infected and control plants for further analyses. Each sample consisted of the leaves of one tree. Three biological replicates were used for each line.

Whole-transcriptome microarray analysis of Pseudomonas syringae pv. actinidiae CRAFRU 8.43 and Pseudomonas syringae pv. tomato DC3000 grown in apoplast-like conditions supplemented or not with kiwifruit or tomato extract

Project description:Purpose: The outcome of host–pathogen interactions is thought to reflect the offensive and defensive capabilities of both players. When plants interact with Pseudomonas syringae, several well-characterized virulence factors contribute to early bacterial pathogenicity, including the type III secretion system (T3SS), which must be activated by signals from the plant and environment to allow the secretion of virulence effectors. The manner in which these signals regulate T3SS activity is still unclear. Conlusion: the analysis revealed that the perception of plant signals from kiwifruit or tomato extracts anticipates T3SS expression in P. syringae pv. actinidiae compared to apoplast-like conditions

A lipopolysaccharide-dependent phage infects a pseudomonad phytopathogen and can evolve to evade phage resistance

Project description:Bacterial pathogens are major causes of crop diseases, leading to significant production losses. For instance, kiwifruit canker, caused by the phytopathogen Pseudomonas syringae pv. actinidiae (Psa), has posed a global challenge to kiwifruit production. Treatment with copper and antibiotics, whilst initially effective, is leading to the rise of bacterial resistance, requiring new biocontrol approaches. Previously, we isolated a group of closely related Psa phages with biocontrol potential, which represent environmentally sustainable antimicrobials. However, their deployment as antimicrobials requires further insight into their properties and infection strategy. Here, we provide an in-depth examination of the genome of ΦPsa374-like phages and show that they use lipopolysaccharides (LPS) as their main receptor. Through proteomics and cryo-electron microscopy of ΦPsa374, we revealed the structural proteome and that this phage possess a T=9 capsid triangulation, unusual for myoviruses. Furthermore, we show that ΦPsa374 phage resistance arises in planta through mutations in a glycosyltransferase involved in LPS synthesis. Lastly, through in vitro evolution experiments we showed that phage-resistance is overcome by mutations in a tail fiber and structural protein of unknown function in ΦPsa374. This study provides new insight into the properties of ΦPsa374-like phages that informs their use as antimicrobials against Psa.
