Abstract Monitoring the impact of anthropogenic and naturogenic threats on orchid community through diversity, taxonomy conservation studies is necessary. Reintroduction these species to their natural habitat associates with resilience, selection suitable trees sites for regeneration restoration efforts, drives initiative. Upon obtaining an accurate estimate diversity genetic resource conservation, integrative methods classical morphological taxonomy, anatomy (micromorphology), molecular genetics are crucial solve taxonomic uncertainty. Changes in microclimatic conditions structures key determinants both epiphytic terrestrial orchids assemblages following disturbance. Any assessments biodiversity ecosystem service must include variable forest types management regimes provide impartial views effect ecological disturbance community. Accordingly, a plant-microbial ecology study should be included extent human-induced climatic variability towards diversification.

Leaf bacterial microbiota response to flooding is controlled by plant phenology in wheat (Triticum aestivum L.)

Scientific Reports, Journal Year: 2022, Volume and Issue: 12(1)

Published: July 1, 2022

Abstract Leaf microbiota mediates foliar functional traits, influences plant fitness, and contributes to various ecosystem functions, including nutrient water cycling. Plant phenology harsh environmental conditions have been described as the main determinants of leaf assembly. How climate change may modulate is unresolved thus, we a limited understanding on how stresses associated with driven weather events affect composition functions microbes inhabiting phyllosphere. Thus, conducted pot experiment determine effects flooding stress wheat microbiota. Since might be an important factor in response hydrological stress, was induced at different growth stages (tillering, booting flowering). Using metabarcoding approach, monitored bacteria flooding, while key soil traits were measured correlate physiological edaphic changes shifts bacterial In our study, stage represented driver composition, early late plants showed distinct communities. Overall, had differential effect dynamics depending which developmental it induced, more pronounced disruption community assembly observed younger plants.

Response of the wheat mycobiota to flooding revealed substantial shifts towards plant pathogens

Frontiers in Plant Science, Journal Year: 2022, Volume and Issue: 13

Published: Nov. 28, 2022

Rainfall extremes are intensifying as a result of climate change, leading to increased flood risk. Flooding affects above- and belowground ecosystem processes, representing substantial threat crop productivity under change. Plant-associated fungi play important roles in plant performance, but their response abnormal rain events is unresolved. Here, we established glasshouse experiment determine the effects flooding stress on spring wheat-mycobiota complex. Since phenology could be an factor hydrological stress, was induced only once at different growth stages, such tillering, booting flowering. We assessed wheat mycobiota three soil-plant compartments (phyllosphere, roots rhizosphere) using metabarcoding. Key soil traits were measured correlate physiological edaphic changes with shifts structure functional guilds. reduced fitness, caused dramatic assembly across entire plant. Notably, observed transition consisting decline mutualist abundance richness concomitant increase pathogens. Indeed, fungal pathogens associated cereal diseases, Gibberella intricans, Mycosphaerella graminicola, Typhula incarnata Olpidium brassicae significantly flooding. Overall, our study demonstrate detrimental effect complex, highlighting urgent need understand how change-associated abiotic stressors alter plant-microbe interactions crops.

In grapevine decline, microbiomes are affected differently in symptomatic and asymptomatic soils

Applied Soil Ecology, Journal Year: 2022, Volume and Issue: 183, P. 104767 - 104767

Published: Dec. 14, 2022

Grapevine decline affects viticulture worldwide. It is caused by a wide range of individual and combined biotic abiotic factors. Some declines remain unexplained because they are not associated with known pathological symptoms or mineral dysregulation. Vineyard microbiological quality an important area study, since grapevine-associated microbiome primarily originates in vineyard soils determines host health development. To understand the decrease growth yield, high mortality plants vineyards affected these declines, multisite study investigated soil microbial communities. Spatial (terroir: two distinct geographical locations) temporal (season: autumn spring) dimensions were added to inter-row status factor (S for areas symptomatic vines AS those asymptomatic vines). The microbiomes S analyzed using high-throughput sequencing based on bacterial 16S rRNA gene, fungal ITS1 region (Internal Transcribed Spacer), 18S gene Glomeromycota family. Geographical location was strongest driver communities, while seasonal influenced community. Based metabarcoding analysis, presented enriched taxa that can be potentially beneficial grapevine growth. In addition, diversity richness, including division, greater soils. Fungal genera diseases detected across all conditions, higher abundances These findings reveal potential source both pathogens microorganisms.
