Published: Oct. 19, 2022

Agriculture production faces many abiotic stresses, mainly drought, salinity, low and high temperature. These stresses inhibit plants’ genetic potential, which is the cause of huge reduction in crop productivity, decrease potent yields for important plants by more than 50% imbalance agriculture’s sustainability. They lead to changes physio-morphological, molecular, biochemical nature change regular metabolism, makes them a leading losses productivity. plant systems also help mitigate stress conditions. To initiate signal during conditions, sensor molecules perceive from outside commence signaling cascade send message stimulate nuclear transcription factors provoke specific gene expression. stress, contain several methods avoidance, adaption, acclimation. In addition these, manage possess tolerance mechanisms involve ion transporters, osmoprotectants, proteins, other associated with transcriptional control, cascades are stimulated offset stress-associated molecular changes. Plant growth survival depends on ability respond stimulus, produce signal, start suitable physiological Various factors, such as biochemical, physiological, plants, including use microbiomes nanotechnology combat highlighted this article.

Published: Aug. 2, 2023

Plant-associated microbes include taxonomically diverse communities of bacteria, archaebacteria, fungi, and viruses, which establish integral ecological relationships with the host plant constitute phyto-microbiome. The phyto-microbiome not only contributes in normal growth development plants but also plays a vital role maintenance homeostasis during abiotic stress conditions. Owing to its immense metabolic potential, provides capability mitigate through various mechanisms like production antioxidants, hormones, bioactive compounds, detoxification harmful chemicals toxins, sequestration reactive oxygen species other free radicals. A deeper understanding structure functions complex mediated mitigation would enable utilization for alleviation crop stress-resistant crops. This review aims at exploring potential alleviate drought, heat, salinity heavy metal finding sustainable solutions enhance agricultural productivity. mechanistic insights into phytomicrobiome imparting tolerance have been summarized, that be helpful novel bioinoculants. high-throughput modern approaches involving candidate gene identification target modification such as genomics, metagenomics, transcriptomics, metabolomics, based genetic engineering discussed wake ever-increasing demand climate resilient plants.

Improving Grapevine Heat Stress Resilience with Marine Plant Growth-Promoting Rhizobacteria Consortia

Microorganisms, Journal Year: 2023, Volume and Issue: 11(4), P. 856 - 856

Published: March 27, 2023

Amid climate change, heatwave events are expected to increase in frequency and severity. As a result, yield losses viticulture due stress have increased over the years. one of most important crops world, an eco-friendly mitigation strategy is greatly needed. The present work aims evaluate physiological fitness improvement by two marine plant growth-promoting rhizobacteria consortia Vitis vinifera cv. Antão Vaz under conditions. To assess potential biophysical biochemical thermal feedback amelioration, photochemical traits, pigment fatty acid profiles, osmotic oxidative biomarkers were analysed. Bioaugmented grapevines exposed presented significantly enhanced photoprotection capability higher thermo-stability, exhibiting lower dissipation energy flux than non-inoculated plants. Additionally, rhizobacterial tested improved light-harvesting capabilities increasing reaction centre availability preserving photosynthetic efficiency. Rhizobacteria inoculation expressed osmoprotectant promotion, revealed osmolyte concentration while maintaining leaf turgidity. Improved antioxidant mechanisms membrane stability resulted lowered lipid peroxidation product formation when compared Although found differ their effectiveness, these findings demonstrate that bioaugmentation induced significant tolerance mitigation. This study promising usage PGPR promote minimize impacts grapevines.

Exploitation of Plant Growth Promoting Bacteria for Sustainable Agriculture: Hierarchical Approach to Link Laboratory and Field Experiments

Microorganisms, Journal Year: 2022, Volume and Issue: 10(5), P. 865 - 865

Published: April 21, 2022

To feed a world population, which will reach 9.7 billion in 2050, agricultural production have to increase by 35-56%. Therefore, more food is urgently needed. Yield improvements for any given crop would require adequate fertilizer, water, and plant protection from pests disease, but their further abuse be economically disadvantageous negative impact on the environment. Using even inputs simply not possible, availability of arable land increasingly reduced due climate changes. improve without consumption natural resources, farmers powerful ally: beneficial microorganisms inhabiting rhizosphere. However, fully exploit benefits these therefore widely market microbial-based products, there are still gaps that need filled, here we describe some critical issues should better addressed.

Scientific interest in the use of environmental microbiomes for risk assessment is rapidly growing, as exemplified by various EFSA opinions. In absence official regulatory guidelines on how to integrate assessment, aims this report are therefore determine whether microbiome studies can be used such purposes, and propose a roadmap integration assessments under EFSA's remit. The identifies current gaps (in terms knowledge from technical point view) barriers that might delay implementation methods, offers recommendations standardised (multi-)omics techniques purposes. Our main findings identified five priorities: (i) defining core (what it encompasses what made of, including identification bioindicators) assess impact any type disturbance; (ii) standardising methodologies protocols, sampling interpretation, guarantee comparability analyses; (iii) developing tools facilitate interpretation; (iv) collecting microbiome-based data shared, curated maintained databases; (v) setting up European Network Microbiome Laboratories reach an agreement standardise studies, interactions between researchers access or samples, actively include multiple stakeholders discussions involving assessment. There both short- longer-term priorities, all which highlight need mobilise concurrently different agencies institutions, well research. also points out capacity building training, acceptance emerging technology, communication issues.
