High speciation rate of niche specialists in hot springs

The ISME Journal, Год журнала: 2023, Номер 17(8), С. 1303 - 1314

Abstract Ecological and evolutionary processes simultaneously regulate microbial diversity, but the their driving forces remain largely unexplored. Here we investigated ecological characteristics of microbiota in hot springs spanning a broad temperature range (54.8–80 °C) by sequencing 16S rRNA genes. Our results demonstrated that niche specialists generalists are embedded complex interaction dynamics. On thermal tolerance axis, (T) sensitive (at specific temperature) versus T-resistant least five temperatures) species were characterized different breadth, community abundance dispersal potential, consequently differing potential trajectory. The niche-specialized T-sensitive experienced strong barriers, leading to completely shift high fitness low abundant communities at each (“home niche”), such trade-offs thus reinforced peak performance, as evidenced speciation across temperatures increasing diversification with temperature. In contrast, advantageous expansion poor local shown wide breadth extinction, indicating these “jack-of-all-trades, master-of-none”. Despite differences, evolutionarily interacted. Specifically, continuous transition from insured exclusion probability relatively constant level temperatures. co-evolution co-adaptation line red queen theory. Collectively, our findings demonstrate could alleviate environmental-filtering-induced negative effect on diversity.

Plant health states may influence the distribution of rhizosphere microorganisms, which regulate plant growth and development. In this study, response bacteria fungi healthy diseased plants compared to bulk microbes was analyzed using high-throughput sequencing. adaptation strategies under potato virus Y (PVY) infection have been studied from a microbial perspective. The diversity community structure varied between soils, but not soils. A LEfSe analysis revealed significant differences different treatments on bacterial fungal compositions identified Roseiflexaceae, Sphingomonas , Sphingobium as biomarkers (BCK), (BHS), (BIS) respectively; Rhodotorula Ascomycota_unidentified_1_1 were (FCK) (FHS) Bacterial networks found be more complex compact than roles network keystone taxa. PVY further increased connectedness among taxa improve stability resistance environmental stress. Additionally, water content (WC) played an apparent diversity, pH showed effects diversity.

Metabolic interdependencies in thermophilic communities are revealed using co-occurrence and complementarity networks

Nature Communications, Год журнала: 2024, Номер 15(1)

Опубликована: Сен. 17, 2024

Microbial communities exhibit intricate interactions underpinned by metabolic dependencies. To elucidate these dependencies, we present a workflow utilizing random matrix theory on metagenome-assembled genomes to construct co-occurrence and complementarity networks. We apply this approach temperature gradient hot spring, unraveling the interplay between thermal stress cooperation. Our analysis reveals an increase in frequency of with rising temperatures. Amino acids, coenzyme A derivatives, carbohydrates emerge as key exchange metabolites, forming foundation for syntrophic which commensalistic take greater proportion than mutualistic ones. These exchanges are most prevalent phylogenetically distant species, especially archaea-bacteria collaborations, crucial adaptation harsh environments. Furthermore, identify significant positive correlation basal metabolite genome size disparity, potentially signifying means streamlined leverage cooperation metabolically richer partners. This phenomenon is also confirmed another composting system has similar wide range fluctuations. provides feasible way decipher mechanisms underlying microbial interactions, our findings suggested environmental regulates cooperative strategies thermophiles, while dependencies have been hardwired into their during co-evolutions.

Despite the fact that physical and chemical processes have been widely proposed to explicate stabilization mechanisms of soil organic carbon (SOC), thebioavailability SOC linked structure, microbial community functional genes remains poorly understood. This study aims investigate division based on bioavailability differences formed by isolation, clarify relationships with elements, pore characteristics, activity. Results revealed element abundances such as SOC, TN, DOC ranked in same order porosity clay > silt ≥ coarse sand fine both top sub soil. In contrast clay, which had reduced bioavailability, dramatically enhanced compared bulk The bacterial fungal structure was significantly influenced particle size, porosity, elements. Copiotrophic bacteria were more prevalent than also contained oligotrophic bacteria. positively correlated genes, C degradation copiotrophic bacteria, but negatively biomass (p < 0.05). indicated divided into pools varying levels fractions having bioavailable finer fractions. Proteobacteria Acidobacteria, Firmicutes, Gemmatimonadetes made up majority mineralization. Additionally, fungi Mortierellomycota Mucoromycota, are mostly involved mineralization, may potential for metabolism. Our results particle-size fractionation could influence restricting accessibility activity, thus a significant impact sustaining reserves temperate agricultural ecosystems, provided new research direction stability.
