Bacterial pathogens have been of considerable interest in the field plant pathology as they are known to cause serious constraints crop production once infected. When environmental conditions favor disease development, well-known bacterial including Pseudomonas syringae, Ralstonia spp., and Xanthomonas spp. exert severe harmful impacts across a variety plants. The infect tissues' extracellular spaces release virulence factors directly into cytosol or apoplast host plant. In this context, developing long-lasting effective methods for controlling infections becomes essential maintaining sustainable agricultural production. However, conventional such copper-based bactericides antibiotics often proven be ineffective also adversely affect human health environment. Therefore, immense challenges offered by diseases global agriculture encouraged environment-friendly alternatives chemical pesticides. Abiotic elicitors chemicals with non-biological origins that activate defense mechanisms can potentially help protection. Numerous abiotic shown impressive effectiveness boosting defenses against infections, employing multiple induced resistance various crops. present review explores rapidly discusses their role strengthening through induction resistance, understanding immunity, highlighting both potential benefits current strengthen food security.

The evolving threat of new pathogen variants in the face global environmental changes poses a risk to sustainable crop production. Predicting and responding how climate change affects plant-pathosystems is challenging, as environment host-pathogen interactions from molecular community level, with eco-evolutionary feedbacks at play. To address this knowledge gap, we studied short-term within-host pathogen, Xanthomonas perforans, on resistant susceptible pepper open-top chambers (OTCs) under elevated Ozone (O3) conditions single growing season. We observed increased disease severity greater variance cultivar O3, yet no apparent cultivar. Despite dominance genotype cultivar, supported heterogeneous population. Altered O3 levels led strain turnover, relatively gene flux Both standing genetic variation de novo parallel mutations contributed toward evolutionary modifications during adaptation onto presence however, higher polymorphism, random transient mutations. Population heterogeneity along variation, promotion interdependency are mechanisms by which responds stressors. While may provide clues predicting long-term evolution adaptive potential. And, high proportion suggest less predictable climatic alterations. This relevant study emergence constraints underlying shifts.

Plants are associated with a large diversity of microbes, and these complex plant-associated microbial communities critical for plant health. Welsh onion ( Allium fistulosum L.) is one the key oldest vegetable crops cultivated in Taiwan. The leaf famous spices Taiwanese cuisine, thus, it crucial to control foliar diseases. In recent years, cultivation Taiwan has been severely threatened by occurrence blight disease, greatly affecting their yield quality. However, overall picture microbiota still not clear as most etiological investigations were heavily based on isolation microorganisms from diseased plants.

Twice postponed due Covid-19, this in-person conference covered wide-ranging but intersecting topics related microbiology leaves (and other aboveground parts plants), including phytopathology, food safety, plant physiology, microbial ecology, fluid physics, vegetation science, single-cell biology, canopy architecture, human health. The overarching theme meeting (“understanding rules phyllospheric life”) was explored in 46 podium 12 poster presentations. It fueled formal informal discussions among 90-plus participants about existing new questions phyllosphere microbiology.
