Plant phenotype is a complex entity largely controlled by the genotype and various environmental factors. Importantly, co-evolution has allowed plants to coexist with biotic factors in their surroundings. Recently, plant endophytes as an external phenotype, forming part of plethora microbial assemblage, have gained immense attention from scientists. Functionally, impact many ways, including increasing nutrient availability, enhancing ability cope both abiotic stress, accumulation important secondary metabolites. The current state research been devoted evaluating phenotypic impacts on host plants, direct influence metabolite stress response. However, there knowledge gap how genetic interaction pathogens, other communities, eventually controlling extended phenotype. This review will summarize can abundance functional diversity endophytic community, gene expression, host–endophyte–pathogen disease triangle. information provide novel insights into breeders could specifically target plant–endophyte for crop improvement.

Abstract Entomopathogenic fungi capable of establishing mutualistic endophytic relationships with plants have a tremendous potential as biocontrol agents insect pests. While long played an important and highly effective role in pest suppression, the utility entomopathogenic management is relatively new emerging topic biocontrol. Here we discuss relevance to plant health general, synthesize current knowledge effectiveness against diverse pests, indirect plant‐mediated effects on arthropods, describe benefits that are likely affect herbivores pathogens well. Lastly, consider major challenges incorporating biocontrol, such their non‐target field efficacy, which can be variable influenced by environmental factors. Continued research endophyte–insect–plant–environment interactions critical advancing our these sustainable tactic. © 2024 The Author(s).

Impacts of continuous cropping on the rhizospheric and endospheric microbial communities and root exudates of Astragalus mongholicus

BMC Plant Biology, Год журнала: 2024, Номер 24(1)

Опубликована: Апрель 26, 2024

Astragalus mongholicus is a medicinal plant that known to decrease in quality response continuous cropping. However, the differences root-associated microbiome and root exudates rhizosphere soil may lead these decreases are barely under studies. We investigated biomass production, microbiota, of A. grown two different fields: virgin (Field I) long-term cropping field II). Virgin has never been cultivated for mongholicus. Plant physiological measurements showed reduced fresh dry weight conditions (i.e. Field High-throughput sequencing fungal bacterial communities revealed diversity between samples from fields, including enrichment potentially pathogenic fungi roots II. Metabolomic analysis yielded 20 compounds differed relative abundance fields. Four metabolites (2-aminophenol, quinic acid, tartaric maleamate) inhibited growth mongholicus, soil-borne pathogen Fusarium oxysporum, or both. This comprehensive enhances our understanding microbiome, exudates, interactions These results offer new information future design effective, economical approaches achieving food security.

Bacterial Endophytes and Their Contributions to Alleviating Drought and Salinity Stresses in Wheat: A Systematic Review of Physiological Mechanisms

Agriculture, Год журнала: 2024, Номер 14(5), С. 769 - 769

Опубликована: Май 16, 2024

Drought and salinity stresses significantly threaten global wheat productivity, limiting growth reducing yields, thus endangering food security worldwide. These disrupt physiological processes, impair photosynthesis, hinder optimal yield by diminishing water uptake, causing osmotic stress, ion toxicity, oxidative stress. In response, various mitigation strategies have been explored, including breeding for stress-tolerant cultivars, improved irrigation techniques, the application of exogenous osmoprotectants soil amendments. Among these strategies, emergence rhizospheric endophytic growth-promoting microorganisms has attracted significant attention. Therefore, a systematic review was undertaken to illustrate role bacteria in enhancing tolerance drought stresses. This analyzes mechanisms research trends, identifies gaps, discusses implications sustainable agriculture. An analysis literature related conducted using databases major publishers from 2004 2023. The explores their mechanisms, such as phytohormone production stress-responsive gene induction, emphasizing contribution plant stress resilience. current trends indicate growing interest utilizing mitigate cultivation, with studies focusing on understanding responses interactions plants. Future should concentrate elucidating host multiple stressors, well aspects like mechanism action, lifestyle, transmission pathways. Overall, offer promising avenues agricultural practices, aiding crop resilience amid environmental challenges.

In vitro and In silico investigation deciphering novel antifungal activity of endophyte Bacillus velezensis CBMB205 against Fusarium oxysporum

Scientific Reports, Год журнала: 2025, Номер 15(1)

Опубликована: Янв. 3, 2025

Endophytes from medicinal plants are potential biocontrol agents against Fusarium oxysporum f. sp. cubense (Foc), which is the causative fungus of banana wilt disease. In present study, endophytic bacterium was isolated Globba racemosa and their antagonistic activities Foc were studied, probable molecular mechanism antagonism predicted by docking studies. The 16SrRNA sequencing confirmed isolate to be Bacillus velezensis CBMB205 (EG2). isolates distortion fungal hyphae illustrated in SEM. metabolites identified FTIR, suggesting presence C-H, CH3 O-H groups. Two major such as β-amyrin dihydroxy octadecenoic acid (DA) LC-MS analysis. Molecular studies suggested that these showed binding with chitin synthase 1 1,3-glucan pathogenic fungi. energy (BE) interaction between synthase-1 (CS-1), (1,3-GS) estimated -10.17 kcal/mol − 9.5 kcal/mol, respectively. BE CS-1 1,3-GS determined -2.43 3.4 current study demonstrated EG2 towards provided a silico also provides insight into developing metabolite-based antifungal for various agricultural applications.

Molecular Characterization and Plant Growth Promotion Potential of Paenibacillus Dendritiformis Endophyte Isolated from Tecomella Undulata (Roheda)

Current Agriculture Research Journal, Год журнала: 2025, Номер 12(3), С. 1170 - 1180

Опубликована: Янв. 15, 2025

In this study, we have isolated a bacterial endophyte Paenibacillus dendritiformis strain RAE13 (Accession number: OR259131) from the leaves of Tecomella undulata (Roheda) plant. The identification species was carried out using 16s-rDNA ribotyping. Subsequently, gauged for its potential to endorse plant growth through various mechanisms such as nitrogen fixation, IAA production, HCN synthesis, siderophore generation, and ammonia production. Furthermore, evaluation focused on endophyte's capacity producing extracellular enzymes, including cellulase, chitinase, protease, amylase, catalase. exhibited synthesize an average 18±0.375 μg/ml indole-3-acetic acid (IAA) after being subjected concentration 5 mg/ml tryptophan over 14-day incubation period. endophytic isolate RAE 13 produced 42.4±0.004 Gibberellin, solubilized phosphate in range 70.2 135.5 μg/ml, 45.5 ammonia. phylogenetic analysis unveiled that had common ancestor maximum nucleotide sequence similarity 98.30% with sp isolates Uttar Pradesh, India. To diminish consumption chemicals conventional farming, results indicated great growth-stimulating inoculant. Henceforward, utilization these enzymes medical industrial applications will be highly beneficial.
