Journal of Advanced Research, Journal Year: 2019, Volume and Issue: 19, P. 29 - 37

Published: March 20, 2019

Plants have evolved with a plethora of microorganisms having important roles for plant growth and health. A considerable amount information is now available on the structure dynamics microbiota as well functional capacities isolated community members. Due to interesting potential due current challenges in crop production there an urgent need bring microbial innovations into practice. Different approaches microbiome improvement exist. On one hand strains or strain combinations can be applied, however, field success often variable urgently required. Smart, knowledge-driven selection needed use suitable delivery formulations. other hand, farming practices genotype influence thus functioning. Therefore, appropriate breeding leading improved plant-microbiome interactions are avenues increase benefit microbiota. In conclusion, different making new generation inoculants application microbiome-based agro-management lines could lead better microbiome.

Microbial interactions within the plant holobiont

Microbiome, Journal Year: 2018, Volume and Issue: 6(1)

Published: March 27, 2018

Since the colonization of land by ancestral plant lineages 450 million years ago, plants and their associated microbes have been interacting with each other, forming an assemblage species that is often referred to as a "holobiont." Selective pressure acting on holobiont components has likely shaped plant-associated microbial communities selected for host-adapted microorganisms impact fitness. However, high densities detected tissues, together fast generation time more ancient origin compared host, suggest microbe-microbe interactions are also important selective forces sculpting complex assemblages in phyllosphere, rhizosphere, endosphere compartments. Reductionist approaches conducted under laboratory conditions critical decipher strategies used specific cooperate compete within or outside tissues. Nonetheless, our understanding these shaping communities, along relevance host health natural context, remains sparse. Using examples obtained from reductionist community-level approaches, we discuss fundamental role (prokaryotes micro-eukaryotes) community structure health. We provide conceptual framework illustrating among microbiota members establishment maintenance host-microbial homeostasis.

Agricultural intensification reduces microbial network complexity and the abundance of keystone taxa in roots

The ISME Journal, Journal Year: 2019, Volume and Issue: 13(7), P. 1722 - 1736

Published: March 8, 2019

Root-associated microbes play a key role in plant performance and productivity, making them important players agroecosystems. So far, very few studies have assessed the impact of different farming systems on root microbiota it is still unclear whether agricultural intensification influences structure complexity microbial communities. We investigated conventional, no-till, organic wheat fungal communities using PacBio SMRT sequencing samples collected from 60 farmlands Switzerland. Organic harbored much more complex network with significantly higher connectivity than conventional no-till systems. The abundance keystone taxa was highest under where lowest. also found strong negative association (R2 = 0.366; P < 0.0001) between connectivity. occurrence best explained by soil phosphorus levels, bulk density, pH, mycorrhizal colonization. majority are known to form arbuscular associations plants belong orders Glomerales, Paraglomerales, Diversisporales. Supporting this, fungi roots soils farming. To our knowledge, this first study report for agroecosystems, we demonstrate that reduces microbiome.

Forest microbiome: diversity, complexity and dynamics

FEMS Microbiology Reviews, Journal Year: 2016, Volume and Issue: unknown, P. fuw040 - fuw040

Published: Oct. 11, 2016

Globally, forests represent highly productive ecosystems that act as carbon sinks where soil organic matter is formed from residuals after biomass decomposition well rhizodeposited carbon. Forests exhibit a high level of spatial heterogeneity and the importance trees, dominant primary producers, for their structure functioning. Fungi, bacteria archaea inhabit various forest habitats: foliage, wood living bark surface, ground vegetation, roots rhizosphere, litter, soil, deadwood, rock surfaces, invertebrates, wetlands or atmosphere, each which has its own specific features, such nutrient availability temporal dynamicy drivers affect microbial abundance, dominance fungi composition communities. However, several microorganisms, in particular fungi, even connect multiple habitats, most ecosystem processes habitats. are dynamic on broad scale with ranging short-term events over seasonal dynamics to long-term stand development disturbances fires insect outbreaks. The understanding these can be only achieved by exploration complex 'ecosystem microbiome' functioning using focused, integrative microbiological ecological research performed across

Forest Soil Bacteria: Diversity, Involvement in Ecosystem Processes, and Response to Global Change

Microbiology and Molecular Biology Reviews, Journal Year: 2017, Volume and Issue: 81(2)

Published: April 12, 2017

The ecology of forest soils is an important field research due to the role forests as carbon sinks. Consequently, a significant amount information has been accumulated concerning their ecology, especially for temperate and boreal forests. Although most studies have focused on fungi, soil bacteria also play roles in this environment. In soils, inhabit multiple habitats with specific properties, including bulk soil, rhizosphere, litter, deadwood habitats, where communities are shaped by nutrient availability biotic interactions. Bacteria contribute range essential processes involved cycling carbon, nitrogen, phosphorus. They take part decomposition dead plant biomass highly fungal mycelia. rhizospheres trees, interact roots mycorrhizal fungi commensalists or mycorrhiza helpers. mediate critical steps nitrogen cycle, N fixation. Bacterial respond effects global change, such climate warming, increased levels dioxide, anthropogenic deposition. This response, however, often reflects specificities each studied ecosystem, it still impossible fully incorporate into predictive models. understanding bacterial advanced dramatically recent years, but incomplete. exact extent contribution ecosystem will be recognized only future, when activities all community members simultaneously.

The plant endosphere contains a diverse group of microbial communities. There is general consensus that these communities make significant contributions to health. Both recently adopted genomic approaches and classical microbiology techniques continue develop the science plant-microbe interactions. Endophytes are symbionts residing within for majority their life cycle without any detrimental impact host plant. use natural offers an opportunity maximize crop productivity while reducing environmental impacts agriculture. promote growth through nitrogen fixation, phytohormone production, nutrient acquisition, by conferring tolerance abiotic biotic stresses. Colonization endophytes crucial providing benefits Endophytic colonization refers entry, multiplication endophyte populations Lately, microbiome research has gained considerable attention but mechanism allowing plants recruit largely unknown.
