Fungal endophytes in plants and their relationship to plant disease

Current Opinion in Microbiology, Journal Year: 2022, Volume and Issue: 69, P. 102177 - 102177

Published: July 20, 2022

The enigmatic endophytic fungi are beginning to reveal their secrets. Like pathogens, they can manipulate the host for own benefit create optimal habitat. Some manipulations induce resistance or otherwise outcompete pathogens and thus be exploited biological control. other symbionts, endophytes produce effector proteins molecules, ranging from specialised metabolites, phytohormones microRNAs, hosts microorganisms meet. There is a continuum endophyte pathogen: some organisms infest cause disease in hosts, but not others. Molecular genetics approaches coupled with functional characterisation have demonstrated worth understanding phenomena underlying fungal interactions.

Molecular Insights into Plant–Microbe Interactions: A Comprehensive Review of Key Mechanisms

Frontiers in Bioscience-Elite, Journal Year: 2024, Volume and Issue: 16(1)

Published: March 12, 2024

In most ecosystems, plants establish complex symbiotic relationships with organisms, such as bacteria and fungi, which significantly influence their health by promoting or inhibiting growth. These involve biochemical exchanges at the cellular level that affect plant physiology have evolutionary implications, species diversification, horizontal gene transfer, symbiosis mutualism, environmental adaptation, positive impacts on community structure biodiversity. For these reasons, contemporary research, moving beyond observational studies, seeks to elucidate molecular basis of interactions; however, gaps in knowledge remain. This is particularly noticeable understanding how distinguish between beneficial antagonistic microorganisms. light above, this literature review aims address some exploring key mechanisms common interspecies relationships. Thus, our study presents novel insights into archetypes, focusing antibiosis process microbial signaling, including chemotaxis quorum sensing.

PLaBAse: A comprehensive web resource for analyzing the plant growth-promoting potential of plant-associated bacteria

bioRxiv (Cold Spring Harbor Laboratory), Journal Year: 2021, Volume and Issue: unknown

Published: Dec. 15, 2021

ABSTRACT Plant-beneficial microorganisms are gaining importance for sustainable plant production and phytosanitary practices. Yet there is a lack of computational approaches targeting bacterial traits associated with growth-promotion (PGP), which hinders the in-silico identification, comparison, selection phytostimulatory strains. To address this problem, we have developed new web resource PLaBAse (v1.01, http://plabase.informatik.uni-tuebingen.de/pb/plabase.php ), provides number services, including (i) database screening 5,565 plant-associated bacteria (PLaBA-db), (ii) tool predicting growth-promoting (PGPTs) single genomes (PGPT-Pred), (iii) prediction plant-association by marker gene identification (PIFAR-Pred). The latter was Martínez-García et al. now hosted at University Tuebingen. PGPT-Pred based on our PGPT ontology, literature- OMICs-curated, comprehensive, hierarchical collection ∼6,900 PGPTs that 6,965,955 protein sequences. study distribution across different environments, applied it to 70,540 strains seven environments (including plants), five spheres (organs), two bacteria-induced phenotypes. This analysis revealed plant-symbiotic generally larger genome size higher count PGPT-annotated encoding genes. Obviously, not all reported restricted -or only enriched in-plant-associated symbiotic bacteria. Some also occur in human- animal-associated bacteria, perhaps due transmission PGP (PGPBs) between or because some functions involved adaption processes various environments. Here provide an easy-to-use approach phyla isolation sites, using PLaBA-db, standardized annotation, PGPT-Pred. We believe will improve understanding about entire facilitate PGPB as bio-inoculants biosafety strategies, so help establish targeted bacteria-incorporated systems future.

Plants in nature interact with other species, among which are mutualistic microorganisms that affect plant health. The co-existence of microbial symbionts the host contributes to fitness a natural context. In turn, composition microbiota responds environment and state host, raising possibility it can be engineered benefit plant. However, technology for engineering structure microbiome is not yet available.The loss diversity reduction population density Streptomyces globisporus SP6C4, core microbe, was observed coincident aging strawberry plants. Here, we show glutamic acid reshapes community enriches populations Streptomyces, functional microbe anthosphere.

The baseline is already shifted: marine microbiome restoration and rehabilitation as essential tools to mitigate ecosystem decline

Frontiers in Marine Science, Journal Year: 2023, Volume and Issue: 10

Published: June 30, 2023

Climate change is turning formerly pristine ecosystems into ever-changing states, causing major disturbance and biodiversity loss. Such impacted marine organisms exhibit clear microbiome shifts that alter their function. Microbiome-targeted interventions appear as feasible tools to support organismal ecosystem resilience recovery by restoring symbiotic interactions thwarting dysbiotic processes. However, restoration rehabilitation are perceived drastic measures, since they ‘natural relationships’. What missing from this notion microbiomes already drastically differ any pre-anthropogenic state. As such, our perception definition of even ‘pristine states’ may in fact represent an disturbed/derived condition. Following this, we argue rehabilitating essential mitigate decline.

Phyllosphere symbiont promotes plant growth through ACC deaminase production

The ISME Journal, Journal Year: 2023, Volume and Issue: 17(8), P. 1267 - 1277

Published: June 1, 2023

Plant growth promoting bacteria can confer resistance to various types of stress and increase agricultural yields. The mechanisms they employ are diverse. One the most important genes associated with in plant biomass is acdS, which encodes a 1-aminocyclopropane-1-carboxylate- or ACC-deaminase. non-proteinogenic amino acid ACC precursor means long-distance transport ethylene, hormone arrest. Expression acdS reduces induced ethylene levels enzyme abundant rhizosphere colonizers. Whether hydrolysis plays role phyllosphere, both as assembly cue promotion, remains unclear. Here we show that Paraburkholderia dioscoreae Msb3, yam phyllosphere symbiont, colonizes tomato promotes by action its deaminase. We found required for improved but not efficient leaf colonization. Strain Msb3 readily proliferates on surface tomato, only occasionally spreading endosphere through stomata. strain also colonize soil medium around roots spreads into root if wounded.
