Microbes colonizing each compartment of terrestrial plants are indispensable for maintaining crop health. Although corn stalk rot (CSR) is a severe disease affecting maize (Zea mays) worldwide, the mechanisms underlying host–microbe interactions across vertical compartments in plants, which exhibit heterogeneous CSR-resistance, remain largely uncharacterized. Here, we investigated microbial communities associated with CSR-resistant and CSR-susceptible cultivars using multi-omics analysis coupled experimental verification. Maize resistant to CSR reshaped microbiota recruited Bacillus species three phenotypes against Fusarium graminearum including niche pre-emption, potential secretion antimicrobial compounds, no inhibition alleviate pathogen stress. By inducing expression Tyrosine decarboxylase 1 (TYDC1), encoding an enzyme that catalyzes production tyramine dopamine, isolates do not directly suppress infection induced synthesis berberine, isoquinoline alkaloid inhibits growth. These beneficial bacteria were from rhizosphere transferred stems but grains plants. The current study offers insight into how respond interact their microbiome lays foundation preventing treating soil-borne pathogens.

Seasonal variations of environmental factors generally result in considerable changes microbiomes, yet we still lack a clear understanding how microbial communities maintain their ecological stability. Here, analyze long-term (nine years) high-throughput sequencing dataset by network analysis to illustrate the stability varies among seasons lake ecosystems. The results showed that networks were distinctly different seasons, and most complex autumn exhibited highest We found strong connecting structures microbes (large modules) significantly (P < 0.05) correlated with water temperature pH, which would negatively affect keystone taxa destabilize communities. more stable removal unstable networks.

"Plastisphere", microbial communities colonizing plastic debris, has sparked global concern for marine ecosystems. Microbiome inhabiting this novel human-made niche been increasingly characterized; however, whether the plastisphere holds crucial roles in biogeochemical cycling remains largely unknown. Here we evaluate potential of biotic and abiotic denitrification nitrous oxide (N2O) production estuaries. Biofilm formation provides anoxic conditions favoring denitrifiers. Comparing with surrounding bulk water, exhibits a higher denitrifying activity N2O production, suggesting an overlooked source. Regardless bacterial fungal denitrifications are main regulators instead chemodenitrification. However, contributions bacteria fungi different from those indicating distinct pattern plastisphere. These findings pinpoint as source, provide insights into new biotope Anthropocene.

Abstract Global changes such as seawater intrusion and freshwater resource salinization increase environmental stress imposed on the aquatic microbiome. A strong predictive understanding of responses microbiome to will help in coping with “gray rhino” events environment, thereby contributing an ecologically sustainable future. Considering that microbial ecological networks are tied stability ecosystem functioning abundant rare biospheres different biogeographic patterns important drivers functioning, roles maintaining need be clarified. Here we showed that, increasing salinity induced by freshwater‐to‐seawater transition, diversity reduced significantly taxonomic structure experienced a succession. The complexity were diminished stress. composition microorganisms supporting underwent sharp turnovers during biosphere behaving more robustly than biosphere. Notably, played much role stabilizing under low‐stress environments, but difference between their relative importance narrowed stress, suggesting weakened “Matthew effect” world. With in‐depth insights into ecology our findings highlight adjusting conservation strategies for maintain functions services response rising

Afforestation is an effective approach to rehabilitate degraded ecosystems, but often depletes deep soil moisture. Presently, it not known how afforestation-induced decrease in moisture affects microbial community and functionality, hindering our ability understand the sustainability of rehabilitated ecosystems. To address this issue, we examined impacts 20 years afforestation on bacterial community, co-occurrence pattern, functionalities along vertical profile (0-500 cm depth) a semiarid region China's Loess Plateau. We showed that effects with deep-rooted legume tree cropland were greater than top layers, resulting decreased beta diversity, more responsive taxa functional groups, increased homogeneous selection, network robustness soils (120-500 cm). Organic carbon nitrogen decomposition rates multifunctionality also significantly by afforestation, limitation soils. Moreover, changes functionality layer was largely related Such negative should be fully considered for assessing afforestation's eco-environment ecosystems because have important influence forest arid climates.
