Journal ArticleDOI
Cadmium-tolerant plant growth-promoting bacteria associated with the roots of Indian mustard (Brassica juncea L. Czern.).
Andrey A. Belimov,Nikos Hontzeas,Vera I. Safronova,S. V. Demchinskaya,Giovanna Piluzza,Simonetta Maria Bullitta,Bernard R. Glick +6 more
TL;DR: A positive correlation between the in vitro ACC deaminase activity of the bacteria and their stimulating effect on root elongation suggested that utilization of ACC is an important bacterial trait determining root growth promotion.
Journal ArticleDOI
Reaction mechanisms of mononuclear non-heme iron oxygenases.
TL;DR: This review presents and analyzes results obtained in the past 6 years from primary sequences, structure-function relationships, and chemical kinetics and mechanisms, dealing with mononuclear non-heme iron interand intramolecular dioxygenases.
Journal ArticleDOI
Rhizosphere bacteria containing 1-aminocyclopropane-1-carboxylate deaminase increase yield of plants grown in drying soil via both local and systemic hormone signalling
Andrey A. Belimov,Ian C. Dodd,Nikos Hontzeas,Julian C. Theobald,Vera I. Safronova,William J. Davies +5 more
TL;DR: Soil inoculation with a natural root-associated bacterium Variovorax paradoxus 5C-2 increased yield and nutritive value of plants grown in drying soil, via both local and systemic hormone signalling.
Journal ArticleDOI
Expression and characterization of 1-aminocyclopropane-1-carboxylate deaminase from the rhizobacterium Pseudomonas putida UW4: a key enzyme in bacterial plant growth promotion
TL;DR: The enzyme 1-aminocyclopropane-1-carboxylate deaminase (ACCD) converts ACC, the precursor of the plant hormone ethylene, to alpha-ketobutyrate and ammonium and was determined to be alpha-helical by circular dichroism (CD).
Journal ArticleDOI
Pseudomonas brassicacearum strain Am3 containing 1-aminocyclopropane-1-carboxylate deaminase can show both pathogenic and growth-promoting properties in its interaction with tomato
TL;DR: The results suggest that bacterial ACC deaminase of P. brassicacearum Am3 can promote growth in tomato by masking the phytopathogenic properties of this bacterium.
