In drought-prone soils, plant growth-promoting rhizobacteria (PGPR) and arbuscular mycorrhizal fungus (AMF) might positively affect water uptake crop yield via rhizosphere interactions. Sole combined additions of Bacillus amyloliquefaciens producing 1-aminocyclopropane-1-carboxylic acid (ACC) deaminase Rhizophagus irregularis into rhizospheric soils were performed under well-watered (WW; 80% fi...

The enzyme 1-aminocyclopropane-1-carboxylate deaminase (ACCD) converts ACC, the precursor of the plant hormone ethylene, to alpha-ketobutyrate and ammonium. This enzyme has been identified in soil bacteria and has been proposed to play a key role in microbe-plant association. A soluble recombinant ACCD from Pseudomonas putida UW4 of molecular weight 41 kDa has been cloned, expressed, and purifi...

OBJECTIVE To determine the molecular basis of a severe neurologic disorder in a large consanguineous family with complete agenesis of the corpus callosum (ACC), pontocerebellar hypoplasia (PCH), and peripheral axonal neuropathy. METHODS Assessment included clinical evaluation, neuroimaging, and nerve conduction studies (NCSs). Linkage analysis used genotypes from 7 family members, and the exo...

Copper (Cu) is an essential element, however it’s excess into the environment causes detrimental effect on plant and risks for public health. Four Cu drought tolerant 1-aminocyclopropane-1-carboxylate (ACC) deaminase producing rhizobacteria were isolated from roots of Trifolium repens L. growing smelter contaminated soils, characterized identified based 16S rRNA gene sequencing. A consortium hi...

The restoration of submerged macrophytes is commonly limited by abiotic stress. Here, we isolated PGPR strains from the rhizosphere using ACC deaminase selective medium, and evaluated their growth promoting effects on Vallisneria natans (V. natans) under low light intensity (or) high sediment organic matter load, also explored indigenous microbiome response V. seedlings to inoculants. Ten isola...

This work aims to study cultivable actinobacterial isolated from the rhizosphere soil of Artemisia herba-alba Asso; an important component Mediterranean dry steppe flora. The isolates functional attributes with respect antifungal, in vitro growth-promotion properties and enzymatic capacities, were studied. A total eleven strains identified as Streptomyces species by 16S rRNA gene sequencing. po...
