Summary Although drought is an increasing problem in agriculture, the contribution of root‐associated bacterial microbiome to plant adaptation water stress poorly studied. We investigated if culturable associated with five grapevine rootstocks and cultivar Barbera may enhance growth under stress. Eight isolates, over 510 strains, were tested vivo for their capacity support The selected strains exhibited a vast array promoting ( PGP ) traits, confocal microscopy observation gfp ‐labelled A...
Background Traditional agro-systems in arid areas are a bulwark for preserving soil stability and fertility, the sight of "reverse desertification". Nevertheless, impact desert farming practices on diversity abundance plant associated microbiome is poorly characterized, including its functional role supporting development under drought stress. Methodology/Principal Findings We assessed structure to drought-sensitive pepper (Capsicum annuum L.) cultivated traditional Egyptian farm, focusing...
Summary Poor iron ( F e) availability in soil represents one of the most important limiting factors agricultural production and is closely linked to physical, chemical biological processes within rhizosphere as a result soil–microorganism–plant interactions. Iron shortage induces several mechanisms organisms, resulting an enhanced release inorganic (such protons) organic (organic acids, carbohydrates, amino phytosiderophores, siderophores, phenolics enzymes) compounds increase solubility...
The association between plant and growth promoting bacteria (PGPB) contributes to the successful thriving of plants in extreme environments featured by water shortage. We have recently shown that, with respect non-cultivated desert soil, rhizosphere pepper cultivated under farming hosts PGPB communities that are endowed a large portfolio PGP traits. Pepper exposed bacterial isolates from exhibited higher tolerance shortage, compared untreated control. This promotion was mediated larger root...
Strawberries are a very popular fruit among berries, for both their commercial and economic importance, but especially beneficial effects human health. However, bioactive compound content is strictly related to the nutritional status of plant might be affected if disorders (e.g. Fe or P shortage) occur. To overcome nutrient shortages, plants evolved different mechanisms, which often involve release root exudates. The biochemical molecular mechanisms underlying exudation its regulation as yet...
Abstract Background Nitrogen is a principal limiting nutrient in plant growth and development. Among factors that may limit NO 3 - assimilation, Fe potentially plays crucial role being metal cofactor of enzymes the reductive assimilatory pathway. Very few information available about changes nitrogen metabolism occurring under deficiency Strategy I plants. The aim this work was to study how cucumber ( Cucumis sativus L.) plants modify their when grown iron deficiency. Results activity...
It has been previously shown that the transgenic overexpression of plant root vacuolar proton pumps H
This paper reports the first biological characterization of a bona fide plant mitovirus in an important crop, Chenopodium quinoa , providing data supporting that mitoviruses have typical features cryptic (persistent) viruses. We, for time, demonstrate are associated with mitochondria plants. In contrast to fungal mitoviruses, not substantially affected by antiviral silencing pathway, and most abundant small RNA length is 16 nt.
Abstract Plastic mulch film residues have been accumulating in agricultural soils for decades, but so far, little is known about its consequences on soil microbial communities and functions. Here, we tested the effects of plastic low-density polyethylene biodegradable films suppressiveness community composition. We investigated how a Fusarium culmorum suppressive affect level disease suppressiveness, plant biomass, nutrient status, rhizosphere using controlled pot experiment. The addition 1%...
Durum wheat is one of the most important agricultural crops, currently providing 18% daily intake calories and 20% protein for humans. However, being that cultivated in arid semiarid areas, its productivity threatened by drought stress, which exacerbated climate change. Therefore, identification tolerant genotypes critical increasing grain yield also improving capability crops to uptake assimilate nutrients, are seriously affected drought. This work aimed determine effect arbuscular...
• In Strategy-I-plants, iron (Fe) deficiency induces processes leading to increased Fe solubilization in the rhizosphere, including reduction by ferric reductases and active proton extrusion. These require respiration function. this work we investigated effect of on respiratory activities cucumber (Cucumis sativus) roots. We compared oxygen consumption rate chain complexes purified mitochondria from roots grown presence or absence using biochemical molecular approaches. Oxygen apex was under...
Iron deficiency induces in Strategy I plants physiological, biochemical and molecular modifications capable to increase iron uptake from the rhizosphere. This effort needs a reorganization of metabolic pathways efficiently sustain activities linked acquisition iron; fact, carbohydrates energetic metabolism has been shown be involved these responses. The aim this work was find both confirmation already expected change enzyme concentrations induced cucumber root tissue response as well new...
Summary Molybdenum (Mo) and iron (Fe) are essential micronutrients required for crucial enzyme activities in plant metabolism. Here we investigated the existence of a mutual control Mo Fe homeostasis cucumber ( Cucumis sativus ). Plants were grown under single or combined starvation. Physiological parameters measured, ionomes tissues proteomes root mitochondria profiled, molybdo‐enzymes synthesis molybdenum cofactor (Moco) evaluated. found to affect each other's total uptake distribution...
In recent decades, agriculture has faced the fundamental challenge of needing to increase food production and quality in order meet requirements a growing global population. Similarly, viticulture also been undergoing change. Several countries are reducing their vineyard areas, several others increasing them. addition, is moving towards higher altitudes latitudes due climate Furthermore, warming exacerbating incidence fungal diseases vineyards, forcing farmers apply agrochemicals preserve...
In plants, Fe homeostasis and O2 metabolism are strictly related, indeed several Fe-requiring enzymes catalyze reactions that also involve oxygen, as a reagent, product, entry or end point of the metabolic pathway in which enzyme takes part. Oxygen sensing itself relies on Fe-dependent enzymes, Plant cysteine oxidase (PCO) family 2-OG independent thiol dioxygenases. PCOs responsible for degradation ERFVII ethylene-responsive factors through proteasomal N-degron connects hypoxia-inducible...
Lanthanum (La) is often used in industry and agriculture, leading to its accumulation natural environments potential ecological risks. The objective of this study was examine the effects on growth, metabolism, nutrient composition Brassica rapa exposed at low (1 µM), medium mM), high (10 mM) La concentrations. We chemical analytical, molecular, metabolomic methods found that exposure induced a hormetic effect, triggering both stimulatory inhibitory responses. reduced aluminum (Al), cobalt...
Abstract Iron (Fe) is essential for plants and humans, with over 2 billion people suffering deficiency disorders because most plant foods, including cereals, are low in Fe. Durum wheat, a staple crop Mediterranean regions, facing increased droughts, which reduce yield ability to acquire use Therefore, understanding mechanisms underlying Fe acquisition accumulation durum wheat under drought both agronomic nutritional purposes. Here, ( Triticum turgidum subsp. ) genotype purple grain pericarp...
In photosynthetic eukaryotes assembly components of iron-sulfur (Fe-S) cofactors have been studied in plastids and mitochondria, but how cytosolic nuclear Fe-S cluster proteins are assembled is not known. We characterized a plant P loop NTPase with sequence similarity to Nbp35 yeast mammals, protein the Cfd1-Nbp35 complex mediating assembly. Genome analysis revealed that NBP35 conserved green lineage CFD1 absent. Moreover, algal lack characteristic CXXC motif C terminus, thought be required...
