Across diverse ecosystems, bacteria and their host organisms engage in complex relationships having negative, neutral, or positive interactions. However, the specific effects of leaf-associated bacterial community functions on plant growth are poorly understood. To address this gap, we explored between function purple pitcher (Sarracenia purpurea). The main aim our research was to investigate how different affect nutrient content plant. Previous had suggested that microbial communities may aid prey decomposition subsequent acquisition carnivorous plants, including S. purpurea. functional roles these uptake not well known. In study, sterile, freshly opened leaves (pitchers) were inoculated with three functionally distinct, pre-assembled examined over 8 weeks. Bacterial composition measured using physiological assays, metagenomics, metatranscriptomics. Distinct affected traits; a enriched secondary metabolite production traits associated larger almost double biomass control pitchers. Physiological differences supported by metatranscriptomic analysis; for example, highest chitinase activity greater expression transcripts enzymes. relationship observed here indicates potential mechanisms host-associated support health growth.

Genome exploration and ecological competence are key to developing effective Pseudomonas-based biocontrol inoculants

Canadian Journal of Plant Pathology, Год журнала: 2023, Номер 45(3), С. 330 - 339

Опубликована: Фев. 27, 2023

Numerous plant-beneficial Pseudomonas strains have been isolated and characterized for their ability to control plant pathogens the diseases they cause under controlled conditions. Only a few have, however, demonstrated consistent field efficacy. Better exploitation of genomic information consideration ecological competence interest could help overcome this major inconsistency. In minireview, we will discuss these two important aspects that consider crucial in development effective biocontrol inoculants. We first explore how increasing availability data can empower researchers who study Pseudomonas-mediated better understand mechanisms at play. then key roles played by successful Pseudomonas-based inoculants select ecologically competent strains. A understanding factors accelerate prevent wasting precious time resources performing experiments with little chance succeed.

Review: Research progress on seasonal succession of phyllosphere microorganisms

Plant Science, Год журнала: 2023, Номер 338, С. 111898 - 111898

Опубликована: Окт. 24, 2023

Phyllosphere microorganisms have recently attracted the attention of scientists studying plant microbiomes. The origin, diversity, functions, and interactions phyllosphere been extensively explored. Many experiments demonstrated seasonal cycles microbes. However, a comprehensive comparison these separate investigations to characterize trends in microbes woody herbaceous plants has not conducted. In this review, we explored dynamic changes non-woody with passage season, sought find driving factors, summarized texts, thought about future research regarding application agricultural production. Seasonal similarities differences, but extensive experimental validation is needed. Climate, insects, hosts, microbial interactions, anthropogenic activities are diverse factors that influence variation microorganisms.

Enhancing Spring Barley Grain Yield with Local Biofertilizers in the Semi-Arid Steppe Zone of Northern Kazakhstan

International Journal of Design & Nature and Ecodynamics, Год журнала: 2024, Номер 19(2), С. 371 - 378

Barley is one of the most important grain crops grown in all agricultural regions world.It unique its chemical composition and health benefits.In Kazakhstan, largest country Central Asia, barley second commodity after wheat.The main goal project was a comparative study effect four local biofertilizers form consortia indigenous soil microorganisms with PGPR PGPF properties on yield spring variety "Tselinny 2005" conditions Kazakhstan semi-arid steppe zone.Employing systematic field trial design, each biofertilizer's impact assessed through application rates methods, comparing against control plots without biofertilizer treatment.Grain meticulously measured post-harvest, accounting for variations environmental conditions, to ascertain biofertilizers' contributions crop productivity.Based results obtained, recommend effective producers.Laboratory tests germination energy, seeds inoculated biofertilizers, post-embryonic development roots shoots showed colonization potential at least three tested biofertilizers.Single-factor experiments over two years that significant benefits employing B1 B4, which not only promote 50% increase but also present sustainable environmentally beneficial alternative synthetic fertilizers, pesticides, fungicides areas subject abiotic biotic stress.Utilizing these could reduce impact, lower production costs, offering holistic approach enhancing productivity regions.
