Friends and Foes: Bacteria of the Hydroponic Plant Microbiome

Plants, Год журнала: 2024, Номер 13(21), С. 3069 - 3069

Опубликована: Окт. 31, 2024

Hydroponic greenhouses and vertical farms provide an alternative crop production strategy in regions that experience low temperatures, suboptimal sunlight, or inadequate soil quality. However, hydroponic systems are soilless and, therefore, have vastly different bacterial microbiota than plants grown soil. This review highlights some of the most prevalent plant growth-promoting bacteria (PGPB) destructive phytopathogenic dominate systems. A complete understanding which increase yields ways to mitigate loss from disease critical advancing microbiome research. The section focussing on putative biological pathways for growth promotion evidence increased productivity by these organisms. Seven genera examined detail, including

Biological Control of Tomato Bacterial Leaf Spots and Its Impact on Some Antioxidant Enzymes, Phenolic Compounds, and Pigment Content

Biology, Год журнала: 2024, Номер 13(6), С. 369 - 369

Опубликована: Май 23, 2024

Tomato bacterial spots, caused by Xanthomonas campestris pv. vesicatoria (Xcv1) and X. euvesicatoria (Xe2), as well specks, two strains of Pseudomonas syringae tomato (Pst1 Pst2), represent significant threats to production in the El-Sharkia governorate, often resulting substantial yield losses. The objective this study was evaluate efficacy various biocontrol culture filtrates, including bacteria fungi agents, managing occurrence severity these diseases, while also monitoring physiological changes leaves, antioxidant enzymes, phenolics, pigment content. filtrates from examined Trichoderma species (T. viride, T. harzianum, album), tested (Bacillus subtilis, fluorescens, Serratia marcescens) at concentrations 25%, 50%, 100%, significantly inhibited proliferation pathogenic In vitro. For vivo experiments, we used specific doses 5 mL spore suspension per plant for fungal bioagents a concentration 2.5 × 107 spores/mL. were applied 10 1 108 CFU/mL. Spraying days before infection reduced disease incidence severity. viride exhibited highest among bioagents, followed harzianum album. Meanwhile, filtrate B. subtilis emerged most potent P. fluorescens. Furthermore, applying resulted elevated levels chitinase, peroxidase, polyphenol oxidase activity. This effect extended increased phenol contents, chlorophyll a, b, carotenoids sprayed plants compared control treatment. Overall, findings underscore potential strategies effectively mitigate enhancing defense mechanisms parameters, thus offering promising avenues sustainable management production.

Sustainable and innovative biological control strategies against Pseudomonas syringae pv. tomato, Pseudomonas savastanoi pv. phaseolicola and Xanthomonas spp. affecting vegetable crops: a review

Frontiers in Plant Science, Год журнала: 2025, Номер 16

Опубликована: Апрель 30, 2025

Genera Pseudomonas and Xanthomonas include bacterial species that are etiological agents of several diseases major vegetable crops, such as tomato, pepper, bean, cabbage cauliflower. The pathogens those genera may cause severe crop damage, leading to symptoms like leaf spots, wilting, blights, rotting. These plant can affect propagation materials spread rapidly through tissues, contaminated soils, or water sources, making them challenging control using conventional chemical products alone. Biopesticides, essential oils (EOs), nowadays studied, tested formulated by employing nano- micro-technologies innovative biological strategies obtain more sustainable less heavy metal ions. Moreover, there is a growing interest in exploring new (BCAs), antagonistic fungal bacteriophages understanding their ecology mechanisms phytopathogens. direct competition for nutrients, production antimicrobial compounds, quorum quenching indirect induction systemic resistance. Optimisation the biocontrol potential goes development nanoparticle-based formulations methods field application, from foliar sprays seed coatings root inoculation, aimed improve microbial stability, shelf life, controlled release performance. Overall, use horticultural crops an area research continues advance shows promising potential. This review aims provide in-depth exploration commercially accessible solutions strategies, with specific focus on management caused species. In this article, we highlighted advancements EOs other BCAs, emphasizing shortcomings disease management. Indeed, despite reduced dependence synthetic pesticides enhanced productivity, variable regulatory frameworks, compatibility among different consistent performance under conditions current challenges commercialization use. seeks contribute valuable insights into evolving landscape guidance effective eco-friendly against diseases.

A Biostimulant Based on Ecklonia maxima and Yeast Extract Increases the Resistance of Tomato Plants Toward Pseudomonas syringae pv. tomato DC3000

Physiologia Plantarum, Год журнала: 2025, Номер 177(3)

Опубликована: Май 1, 2025

ABSTRACT Plant biostimulants represent a promising option to improve agricultural production and stress resistance while reducing the use of fertilizers pesticides. Despite various evidence demonstrating beneficial role in preventing negative effects abiotic on plants, ability bolster defense mechanisms has been brought light only recently. In this work, impact biostimulant based Ecklonia maxima yeast extracts (S/Y) response tomato infected with Pseudomonas syringae pv. DC3000 ( Pst DC3000) was assessed. S/Y selected after screening identify capable conferring DC3000. boosts early events plant's innate immunity. Indeed, biostimulation increased DC3000‐induced oxidative burst by upregulating NADPH oxidase/respiratory oxidase homolog apoplastic class III peroxidases expression. Moreover, deposition callose also promoted. Due improved activation responses S/Y, disease symptoms bacterial spread 72 h infection were significantly reduced. Finally, levels salicylic acid, key hormone plant immunity, whilst those jasmonic acid auxin, which are regulators DC3000, hampered. Overall, these findings show that mitigates acting different mechanisms, thus providing potential plants' biotic stresses.
