Abstract Soil microbiota has increasingly been shown to play an integral role in viticulture resilience. The emergence of new metagenomic and culturomic technologies led significant advances the study microbial biodiversity. In agricultural sector, soil plant microbiomes have found significantly improve resistance environmental stressors diseases, as well influencing crop yields fruit quality thus improving sustainability under shifting environments. Grapevines are usually cultivated a scion grafted on rootstocks, which selected according pedoclimatic conditions cultural practices, known terroir. rootstock connects surrounding vine’s aerial part impacts growth berry quality. Understanding microbiome dynamics is relevant important field study, may be critical This review aims highlight relationship between grapevine roots telluric diversity activity. addition, this explores concept core regarding potential applications engineering with goal enhancing adaptation biotic abiotic stress.

Grassland degradation amplifies the negative effect of nitrogen enrichment on soil microbial community stability

Global Change Biology, Год журнала: 2024, Номер 30(3)

Abstract Although nitrogen (N) enrichment is known to threaten the temporal stability of aboveground net primary productivity, it remains unclear how alters that belowground microbial abundance and whether its impact can be regulated by grassland degradation. Using data from N experiments at temperate grasslands with no, moderate, severe, extreme degradation degrees, we quantified soil (hereafter ‘microbial community stability’) using ratio mean quantitative PCR standard deviation over 4 years. Both bacterial fungal sharply decreased when input exceeded 30 g m −2 year −1 in non‐degraded grasslands, whereas a reduction this threshold occurred degraded grasslands. Microbial species diversity, asynchrony, associations jointly altered stability. Interestingly, linkages between plant were strengthened suggesting plants microbes might depend on each other keep stable communities harsh environments. Our findings highlighted importance regulating responses provided experimental evidence for understanding relationships

Assembly of soil multitrophic community regulates multifunctionality via multifaceted biotic factors in subtropical ecosystems

Environment International, Год журнала: 2025, Номер 195, С. 109272 - 109272

Soil biodiversity underpins multiple ecosystem functions and services essential for human well-being. Understanding the determinants of biodiversity-ecosystem function relationships (BEFr) is critical conservation management soil ecosystems. Community assembly processes determine community diversity structure. However, there remains limited systematic research on how organismal groups affect through their influence species interactions. Here, we analyzed 331 samples from different land-use types (cropland, forest, grassland) in Qinling-Daba Mountains to investigate drivers, processes, network stability multitrophic organisms. High-throughput sequencing was used examine archaea, bacteria, fungi, algae, protozoa, invertebrates, while enzyme activity assays were assess multifunctionality related nutrient provisioning. Our results indicated that biotic factors contributed 62.81-94.97 % α-diversity 4.19-52.37 β-diversity organisms, even when considering abiotic factors. Protozoan α- most significantly explained invertebrates ecosystems, serving as important indicators assessing health. Furthermore, prokaryotes primarily governed by stochasticity (>50 %), whereas those eukaryotic dominated deterministic (<50 %). Diversity increased with greater bacterial communities where stochastic predominated. Conversely, fungal protozoan decreased intensified. Importantly, enhanced increasing α-diversity, β-diversity, stability. These findings provide valuable insights into regulation BEFr processes. Future should further explore role these functioning under change scenarios.

Can we use environmental DNA as holotypes?

Fungal Diversity, Год журнала: 2018, Номер 92(1), С. 1 - 30

Опубликована: Июль 12, 2018

The advantages and disadvantages of giving a valid name to sequence DNA detected from environmental specimens is presently hot debate amongst the mycological community. idea using intracellular ("mgDNA") samples as holotypes seems at face value, be good idea, considering expansion knowledge among these 'dark taxa' or matter fungi' that it could provide (i.e. based taxa without physical formal nomenclature). However, limitations mgDNA needs careful thought, i.e. can we use short fragment, which may contain small amount genetic information, allow discrimination between species? What point are potential problems scientific names mgDNA? Numerous mycologists taxonomists, who have many years experience working on taxonomy phylogeny different groups fungi, concerned about consequences providing mgDNA. There has been much debate, through several publications considerable holotypes. proponents tried virtues Those against shown identification species does not work in fungal groups, while those for cases where identified with Different disciplines reasons opinions holotypes, however even same dissimilar ideas. In this paper explore We evidences our own experiences. no way do attempt degrade study dark taxa, but relate issues taxonomy. fact show value data approaches, dealing discovery already named numbers ecological roles. discuss pitfalls impacts expanding nomenclatural concept also discussed. evidence case studies Botryosphaeria, Colletotrichum, Penicillium Xylaria. cannot due their fragments most ITS result sequencing. conclude highly undesirable naming species.

The Thin Line between Pathogenicity and Endophytism: The Case of Lasiodiplodia theobromae

Agriculture, Год журнала: 2020, Номер 10(10), С. 488 - 488

Опубликована: Окт. 21, 2020

Many fungi reported for endophytic occurrence are better known as plant pathogens on different crops, raising questions about their actual relationships with the hosts and other plants in biocoenosis factors underlying lifestyle shift. This paper offers an overview of Lasiodiplodia theobromae (Dothideomycetes, Botryosphaeriaceae), a species to be able colonize many both endophyte pathogen. Prevalently spread tropical subtropical areas, there concerns that it may propagate temperate region following global warming increasing trade materials. The state art concerning biochemical properties strains this is also examined reference range biotechnological applications.
