Environmental abiotic stresses challenge food security by depressing crop yields often exceeding 50% of their annual production. Different methods, including conventional as well genomic-assisted breeding, mutagenesis, and genetic engineering have been utilized to enhance stress resilience in several species. Plant breeding has partly successful developing varieties against owning the complex genetics traits narrow base germplasm. Irrespective fact that can transfer gene(s) from any organism(s), transgenic crops become controversial mainly due potential risk transgene-outcrossing. Consequently, cultivation is banned certain countries, particularly European countries. In this scenario, discovery CRISPR tool provides a platform for producing transgene-free genetically edited plants—similar mutagenized are not extensively regulated such modified organisms (GMOs). Thus, genome-edited plants without transgene would likely go into field restriction. Here, we focused on deployment development stress-tolerant sustaining productivity under changing environments.

Water deficit affects inter‐kingdom microbial connections in plant rhizosphere

Environmental Microbiology, Год журнала: 2022, Номер 24(8), С. 3722 - 3734

Summary The frequency and severity of drought are increasing due to anthropogenic climate change already limiting cropping system productivity in many regions around the world. Few microbial groups within plant microbiomes can potentially contribute towards fitness their hosts under abiotic stress events including water deficits. However, communities complex integrative work considering multiple co‐existing organisms is needed better understand how entire microbiome responds environmental stresses. We hypothesize that deficit will differentially shape bacterial, fungal, protistan composition influence inter‐kingdom interactions rhizospheres corn sugar beet. used amplicon sequencing profile beet grown irrigated conditions. treatment had a stronger than host species on bacterial composition, whereas opposite was true for protists. These results indicate different kingdoms have variable responses factors. Water also influenced intra‐ associations, wherein protist taxa formed separate cluster Our findings help elucidate drivers community assembly co‐occurrence agricultural rhizosphere environments.

Volatile organic compounds as mediators of plant communication and adaptation to climate change

Physiologia Plantarum, Год журнала: 2022, Номер 174(6)

Опубликована: Ноя. 1, 2022

Abstract Plant volatile organic compounds are the most abundant and structurally diverse plant secondary metabolites. They play a key role in lifespan via direct indirect defenses, attracting pollinators, mediating various interactions between plants their environment. The ecological diversity context‐dependence of plant–plant communication driven by volatiles crucial elements that influence performance different habitats. also valued for multiple applications food, flavor, pharmaceutical, cosmetics industries. In current review, we summarize recent advances have elucidated functions as mediators interaction at community individual levels, highlighting complexities receiver feedback to signals cues. This review emphasizes terpenoids, class compounds, adaptability global climate change stress‐response pathways integral growth survival. Finally, identify research gaps suggest future directions.

Microbiome rescue: directing resilience of environmental microbial communities

Current Opinion in Microbiology, Год журнала: 2023, Номер 72, С. 102263 - 102263

Опубликована: Янв. 17, 2023

Earth's climate crisis threatens to disrupt ecosystem services and destabilize food security. Microbiome management will be a crucial component of comprehensive strategy maintain stable microbinal functions for ecosystems plants in the face change. rescue is directed, community-level recovery microbial populations lost after an environmental disturbance. aims propel resilience trajectory community functions. Rescue can achieved via demographic, functional, adaptive, or evolutionary disturbance-sensitive populations. Various ecological mechanisms support rescue, including dispersal, reactivation from dormancy, functional redundancy, plasticity, diversification, these interact. Notably, controlling dormancy potentially fruitful but underexplored target rescue.

The need for an integrated multi‐OMICs approach in microbiome science in the food system

Comprehensive Reviews in Food Science and Food Safety, Год журнала: 2023, Номер 22(2), С. 1082 - 1103

Опубликована: Янв. 12, 2023

Microbiome science as an interdisciplinary research field has evolved rapidly over the past two decades, becoming a popular topic not only in scientific community and among general public, but also food industry due to growing demand for microbiome-based technologies that provide added-value solutions. expanded context of systems, strongly driven by methodological advances different -omics fields leverage our understanding microbial diversity function. However, managing integrating complex layers are still challenging. Within Coordinated Support Action MicrobiomeSupport (https://www.microbiomesupport.eu/), project supported European Commission, workshop "Metagenomics, Metaproteomics Metabolomics: need data integration microbiome research" gathered 70 participants from relevant discuss challenges promote switch descriptive studies functional studies, elucidating biology interactive roles microbiomes systems. A combination is proposed. This will reduce biases resulting each individual technology result more comprehensive view biological system whole. Although combinations datasets rare, advanced bioinformatics tools artificial intelligence approaches can contribute understanding, prediction, management microbiome, thereby providing basis improvement quality safety.
