Abstract Background and aims Biostimulants of natural origin represent a growing ecological strategy to increase crops productivity, especially when applied in combination with microbial bioeffectors. We studied the effect biostimulants such as Potassium Humates (KH) from Leonardite Compost Tea (CT) green compost on both productivity nutritional status lettuce plants, well primary secondary metabolism treated amended either alone or commercial inoculum (M+), mainly based arbuscular mycorrhizal fungi (Micosat TabPlus). Results The biomass production uptake macro- micronutrients by plants significantly increased mixture humic materials (MIX) combined inoculum. Similarly, synergic MIX_M+ treatment affected more than their individual applications, increasing, respectively, biosynthesis essential amino acids carbohydrates, that antioxidant polyphenolic compounds, hydroxycinnamic acids, flavonols coumarins. Conclusions Our findings suggest calibrated bioactive molecules consortia represents potential tool improve crop its metabolic status.

Published: March 21, 2024

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.

Genome-Wide Association Studies Reveal Genomic Regions Associated With the Response of Wheat (Triticum aestivum L.) to Mycorrhizae Under Drought Stress Conditions

Frontiers in Plant Science, Journal Year: 2018, Volume and Issue: 9

Published: Dec. 4, 2018

In the majority of wheat growing areas worldwide, incidence drought stress has increased significantly resulting in a negative impact on plant development and grain yield. Arbuscular mycorrhizal symbiosis is known to improve tolerance wheat. However, quantitative trait loci (QTL) involved response conditions presence mycorrhizae are largely unknown. Therefore, diverse set consisting 94 bread genotypes was phenotyped under well watered absence mycorrhizae. Grain yield components, related traits as were assessed. parallel, accessions genotyped by using 90k iSelect chip, 15511 polymorphic mapped SNP markers, which used for genome-wide association studies (GWAS). general, compared differed their conditions. Several QTL regions different chromosomes detected associated with components Furthermore, two genome 3D 7D found be Overall, results reveal that inoculation fungi improves exist Further research necessary validate regions. this study may starting point identification candidate genes Maybe future, these initial will help contribute use effectively agriculture combine new approaches i.e., genotypic variation existing breeding programs develop tolerant genotypes.

Protein Profiling of Arabidopsis Roots Treated With Humic Substances: Insights Into the Metabolic and Interactome Networks

Frontiers in Plant Science, Journal Year: 2018, Volume and Issue: 9

Published: Dec. 12, 2018

Background and aim Humic substances (HS) influence the chemical physical properties of soil, are also known to affect plant physiology nutrient uptake. This study aimed elucidate metabolic pathways physiological processes influenced by HS activity. Methods Arabidopsis roots were treated with for eight hours. Quantitative mass spectrometry-based proteomics analysis root proteins was performed using iTRAQ (Isobaric Tag Relative Absolute Quantification) technique. Out 902 protein families identified quantified vs untreated roots, 92 differentially expressed. Bioinformatic tools such as STRING, KEGG, IIS Cytoscape used interpret biological function, pathway visualization network amongst proteins. Results From this it possible evaluate that most expressed functionally classified into several categories, mainly redox homeostasis, response inorganic substances, energy metabolism, synthesis, cell trafficking division. Conclusions In present an overview modified activity is provided. Moreover, from interactomes observe previously undiscovered, novel effects, i.e. on Ubiquitin subnetwork.

Microbes in Cahoots with Plants: MIST to Hit the Jackpot of Agricultural Productivity during Drought

International Journal of Molecular Sciences, Journal Year: 2019, Volume and Issue: 20(7), P. 1769 - 1769

Published: April 10, 2019

Drought conditions marked by water deficit impede plant growth thus causing recurrent decline in agricultural productivity. Presently, research efforts are focussed towards harnessing the potential of microbes to enhance crop production during drought. Microbial communities, such as arbuscular mycorrhizal fungi (AMF) and growth-promoting rhizobacteria (PGPR) buddy up with plants boost productivity drought via microbial induced systemic tolerance (MIST). The present review summarizes MIST mechanisms comprised modulation phytohormonal profiles, sturdy antioxidant defence, osmotic grapnel, bacterial exopolysaccharides (EPS) or AMF glomalin production, volatile organic compounds (VOCs), expression fungal aquaporins stress responsive genes, which alters various physiological processes hydraulic conductance, transpiration rate, stomatal conductivity photosynthesis host plants.

Mapping identified differentially expressed bioinformatics tools such as GO KEGG pathway analysis enrichment gene sets involves metabolic processes, symbiotic signaling, stress/defense responses, energy production, acquisition, biosynthesis essential metabolites. These responsible for root's architectural modification, cell remodeling, cellular homeostasis during phase plant's life. We tried enhance our knowledge that how biological pathways modulate symbiosis?
