A holistic framework integrating plant-microbe-mineral regulation of soil bioavailable nitrogen

Biogeochemistry, Journal Year: 2021, Volume and Issue: 154(2), P. 211 - 229

Published: May 6, 2021

Soil organic nitrogen (N) is a critical resource for plants and microbes, but the processes that govern its cycle are not well-described. To promote holistic understanding of soil N dynamics, we need an integrated model links matter (SOM) cycling to bioavailable in both unmanaged managed landscapes, including agroecosystems. We present framework unifies recent conceptual advances our three steps cycling: (ON) depolymerization solubilization; sorption desorption on mineral surfaces; microbial ON turnover assimilation, mineralization, recycling products. Consideration balance between these provides insight into sources, sinks, flux rates N. By accounting interactions among biological, physical, chemical controls over availability complex mechanisms transformation concrete amenable experimental testing translates ideas new management practices. This will allow researchers practitioners use common measurements particulate (POM) mineral-associated (MAOM) design strategic N-cycle interventions optimize ecosystem productivity minimize environmental loss.The online version contains supplementary material available at 10.1007/s10533-021-00793-9.

Nitrogen Journey in Plants: From Uptake to Metabolism, Stress Response, and Microbe Interaction

Biomolecules, Journal Year: 2023, Volume and Issue: 13(10), P. 1443 - 1443

Published: Sept. 25, 2023

Plants uptake and assimilate nitrogen from the soil in form of nitrate, ammonium ions, available amino acids organic sources. Plant nitrate transporters are responsible for translocation into roots. The unique structure these determines specificity each transporter, structural analyses reveal mechanisms by which function. Following absorption, metabolism pathway incorporates compounds via glutamine synthetase glutamate synthase that convert ions glutamate. Different isoforms exist, enabling plants to fine-tune based on environmental cues. Under stressful conditions, nitric oxide has been found enhance plant survival under drought stress. Furthermore, interaction between salinity stress availability studied, with identified as a potential mediator responses salt Conversely, excessive use fertilizers can lead health issues. Therefore, alternative strategies, such establishing fixation through diazotrophic microbiota, have explored reduce reliance synthetic fertilizers. Ultimately, genomics identify new genes related fixation, could be harnessed improve productivity.

Published: Feb. 12, 2021

Soil-borne microbes are major ecological players in terrestrial environments since they cycle organic matter, channel nutrients across trophic levels and influence plant growth health. Therefore, the identification, taxonomic characterization determination of role members soil microbial communities have become topics interest. The development continuous improvement high-throughput sequencing platforms further stimulated study complex microbiota soils plants. most frequently used approach to composition, diversity dynamics is polymerase chain reaction (PCR), amplifying specific taxonomically informative gene markers with subsequent amplicons. This methodological called DNA metabarcoding. Over last decade, metabarcoding has rapidly emerged as a powerful cost-effective method for description environmental samples. However, this involves several processing steps, each which might introduce significant biases that can considerably compromise reliability output. aim review provide state-of-the-art background knowledge needed make appropriate decisions at step workflow, highlighting crucial steps that, if considered, ensures an accurate standardized studies.
