Soil degradation is a global problem and refers to the reduction or loss of biological economic productive capacity soil resource. In Europe, countries most affected by are undoubtedly those Mediterranean basin. Among these, Italy shows clear signs degradation, with different characteristics, especially in southern regions, where climatic meteorological conditions strongly contribute it. Apulia, Tavoliere plain particular, fragile very sensitive ecosystem due its intrinsic characteristics level anthropic exploitation. Agricultural production pays highest price, as increasing desertification climate change agricultural land severely limit extent available produce food for an ever-growing population. Plant growth-promoting bacteria (PGPB) could be low-cost long-term solution restore fertility, they provide wide range benefits agriculture, including crop productivity, improving nutrient levels inhibiting growth pathogens. This review how PGPB can used improve quality soils, their impact on tolerance abiotic stresses (drought, salinity, heavy metals organic pollutants) feasibility. The use promoted green technology applied marginal areas Apulia increase reduce pollution mitigate impacts change. supported series studies showing that plants inoculated superior non-inoculated plants.

Abstract Background and aims Plant-beneficial microbes may attenuate climate change-induced stresses on plants such as drought. We investigated the potential of beneficial microbial consortia (BMc) plant growth rhizosphere bacterial/archaeal community under Methods Seeds Zea mays B73 were inoculated with six plant-beneficial bacterial isolates either alone or combined in two three-member (BMc1, BMc2) before sowing loamy sandy substrates greenhouse. A known effective consortium (BMc3) was included positive control. Drought treatment established BMc treatments by omitting watering last five weeks period. The maize single determined. Colony-forming units (CFUs) inoculants evaluated selective plating, effects native assessed using 16S rRNA gene amplicon sequencing basal root tip grown loam. Results In both water conditions, CFUs inoculations higher at roots than tips. Under well-watered seed inoculation a isolate had no effect substrates. resulted shoot (but not root) compared to non-inoculated controls conditions zone most important driver for beta-diversity, followed while showed effect. Conclusion Our study suggests that has drought stress during growth.

Climate change and agriculture are intrinsically connected sudden changes in climatic conditions adversely impact global food production security. The climate change-linked abiotic stressors like drought high temperatures resulting crop failure. most severe stress significantly affect the stomatal closure, of reactive oxygen species, transpiration, photosynthesis or other physiological processes plant morphology, growth yield. Therefore, there is an exigent need for cost effective eco-friendly modern technologies to induce tolerance plants leading climate-adapted sustainable agricultural practices sustained production. Among many options being pursued this regard, use promoting microbes (PGPMs) approach promote resilience better productivity. These PGPMs confer resistance via various direct indirect mechanisms including antioxidants, enzymes, exopolysaccharides, modulation phytohormones level, osmotic adjustment by inducing accumulation sugars, along with increases nutrients, water uptake photosynthetic pigments. However, several technological ecological challenges limit their sometimes treatment beneficial fails produce desired results under field conditions. Thus, development synthetic microbial communities host mediated microbiome engineering transgenic capacity express traits may survival present review critically assesses research evidence on potentials genes as develop resilient increased Effective collaboration among scientific communities, policymakers regulatory agencies needed create strong frameworks that both regulate utilization agriculture.

Cereal plants form complex networks with their associated microbiome in the soil environment. A system including variations of numerous parameters properties and host traits shapes dynamics cereal microbiota under drought. These multifaceted interactions can greatly affect carbon nutrient cycling offer potential to increase plant growth fitness drought conditions. Despite growing recognition importance agroecosystem functioning, harnessing root remains a significant challenge due interacting synergistic effects between traits, properties, agricultural practices, drought-related features. better mechanistic understanding root-soil-microbiota associations could lead development novel strategies improve production In this review, we discuss for improving environment suggest roadmap benefits these drought-resilient cereals. methods include conservative trait-based approaches selection breeding genetic resources manipulation environments.

Maize, a vital crop for human nutrition, livestock, and industrial development, faces increasingly severe climatic conditions that hinder its production capacity along with other strategic crops. Novel treatments based on microorganisms have demonstrated efficiency in enhancing plant development responding to stress. The use of bacteria isolated from seeds is novel approach biotreatment, as recent studies point co-evolution process their presence seeds. This hypothesize pre-adaptation host, which may lead increased efficiency. However, several aspects this remain understudied. In study, we aimed evaluate the potential native maize seed microbiota comparison species mitigate drought For characterized seedborne common productive variety Portugal, it biotreatment two varieties (sensitive resistant drought), selecting strain Pseudomonas fulva MB most promising candidate. Stenotrophomonas maltophilia MS-M1 strain, wild alfalfa previously drought-tolerant enhancer, served non-native control strain. . According data, both enhanced vegetative growth when treated individual strains, well consortium, an increase height 5-7% full medium irrigation, 50-55% not irrigated. trend was also observed weight, by 13-23%, even under no irrigation. addition, positively impacted these treatments, amount grain produced (by weight). drought-sensitive experienced 17% while tolerant 25-40% increase. Under irrigation level, about 15% varieties, 100% 140% each variety, respectively, applied. results suggest P. slightly more efficient treatment, outperformed terms productivity varieties. differences were solid enough all parameters consistently asses such difference. consortium treatment only showed better performance or some traits. These findings support very biotreatments, suggesting than strains remarkable beneficial impact (interspecific), expanding possible kind bioinoculants.
