The Glutaminase-Dependent System Confers Extreme Acid Resistance to New Species and Atypical Strains of Brucella

Frontiers in Microbiology, 2017
Neutralophilic bacteria have developed specific mechanisms to cope with the acid stress encountered in environments such as soil, fermented foods, and host compartments. In Escherichia coli, the glutamate decarboxylase (Gad)-dependent system is extremely

Phytosulfokine signalling blocks mycotoxin toxicity in Arabidopsis and mediates suppression of cell death activated by bacterial microbe‐associated molecular patterns

New Phytologist, EarlyView.
Summary Fumonisin B1 (FB1) is a mycotoxin that disrupts ceramide biosynthesis and kills plants. Prior activation with bacterial microbe‐associated molecular patterns (MAMPs), such as components of bacterial flagella, effectively suppresses FB1‐induced cell death.

Screening of 31 Lactic Acid Bacteria Strains Identified Levilactobacillus brevis NCTC 13768 as a High-Yield GABA Producer

Applied Sciences
Gamma-aminobutyric acid (GABA) is the main inhibitory neurotransmitter in the vertebrate central nervous system, known for its role in promoting sleep, reducing anxiety, regulating blood pressure, and modulating stress, cognition, and behavior. Microbial

Polyamines Are Critical for the Induction of the Glutamate Decarboxylase-dependent Acid Resistance System in Escherichia coli *

Journal of Biological Chemistry, 2013
Background: Polyamines are present in all organisms. Results: Polyamines induce various components of the glutamate-dependent acid resistance pathway (GDAR) in Escherichia coli and are important for protection against acid stress.

Optimization of carbon and nitrogen utilization for enhanced photosynthesis, biomass and yield by coexpression of phosphoenolpyruvate carboxylase, aspartate aminotransferase and glutamine synthetase in Brassica juncea

Plant Biotechnology Journal, EarlyView.
Summary Coexpression of genes involved in carbon (C) and nitrogen (N) metabolism offers a promising avenue for improving crop yield. This study investigated the impact of coexpressing phosphoenolpyruvate carboxylase [ZmPEPC (P)], aspartate aminotransferase [GmAspAT (A)] and glutamine synthetase [NtGS (G)] in Brassica juncea to enhance plant yield ...

Foliar Application of Nano‐Selenium Enhances Tea Quality and Selenium Biofortification by Promoting Theanine Synthesis and Nitrogen Metabolism

Plant Biotechnology Journal, EarlyView.
ABSTRACT Selenium (Se) biofortification improves crops' nutritional value, while nano‐selenium (nano‐Se) offers enhanced bioavailability over traditional Se fertilisers. The quality of tea (Camellia sinensis) depends critically on nitrogen (N) metabolism and amino acid balance, particularly of theanine.

Maize Leaf Epiphytic Bacteria Diversity Patterns Are Genetically Correlated with Resistance to Fungal Pathogen Infection

Molecular Plant-Microbe Interactions, 2010
Plant leaves host a specific set of microbial epiphytes. Plant genetic and solar UV-B radiation effects on the diversity of the phyllosphere were examined by measuring epiphytic bacterial ribosomal DNA diversity in a maize recombinant inbred (RI) mapping

Comparative proteomics analysis of root and nodule mitochondria of soybean

Plant, Cell &Environment, EarlyView.
Abstract Legumes perform symbiotic nitrogen fixation through rhizobial bacteroids housed in specialised root nodules. The biochemical process is energy‐intensive and consumes a huge carbon source to generate sufficient reducing power. To maintain the symbiosis, malate is supplied by legume nodules to bacteroids as their major carbon and energy source ...

Phosphate Resupply Differentially Impacts the Shoot and Root Proteomes of Arabidopsis thaliana Seedlings

Plant, Cell &Environment, EarlyView.
ABSTRACT Phosphate (Pi) is an essential macronutrient for plant development that is often limited in soil. Plants have evolved dynamic biochemical, physiological and morphological adaptations to cope with Pi deficiency, known as the Pi starvation response (PSR).
