International audience; Background: The production of secondary metabolites through the culture of entire plants is of great interest. Soilless culture, such as hydroponics, enables the control of plant growth and metabolism. Specific environmental c

Effects of low-molecular-weight organic compounds on sulphur immobilization and re-mineralization and extraction of immobilized sulphur by hot-water and acid hydrolysis

Autor: Sophie Slezack-Deschaumes, P.C. Vong, Séverine Piutti, Armand Guckert, Emile Benizri

Publikováno v: European Journal of Soil Science. 61:287-297

We examined the effects of salicylate, glutamate and glucose on sulphur (S) immobilization and re-mineralization in three calcareous soils: from arable, fallow and forest managements. Each of the three substrates, at a single rate of carbon (1000 mg

Nitrogen fixation and growth of annual Medicago–Sinorhizobium associations at low temperature

Autor: Michel Obaton, Armand Guckert, Kholoud Sultan-Tubeileh, Christophe Robin

Publikováno v: European Journal of Agronomy. 22:267-275

Annual Medicago (medics) represents a great potential of forage production in areas suffering from shortage of livestock feed; however, low winter temperature delays the growth and reduces the nitrogen fixation of medics in Mediterranean dry areas wi

Effects of glucose and rhizodeposits (with or without cysteine-S) on immobilized-35 S, microbial biomass-35 S and arylsulphatase activity in a calcareous and an acid brown soil

Autor: Armand Guckert, Françoise Lasserre-Joulin, O. Dedourge, P.C. Vong, Emile Benizri

Publikováno v: European Journal of Soil Science. 55:649-656

Our aim was to study the effects of C (as glucose and artificial rhizodeposits) on S immobilization, in relation to microbial biomass-S and soil arylsulphatase (ARS) activity, in contrasting soils (a calcareous and an acid brown soil). The glucose-C

Impact of artificial root exudates on the bacterial community structure in bulk soil and maize rhizosphere

Autor: Emile Benizri, Ezékiel Baudoin, Armand Guckert

Publikováno v: Soil Biology and Biochemistry. 35:1183-1192

Bacterial densities, metabolic signatures and genetic structures were evaluated to measure the impact of soil enrichment of soluble organic carbon on the bacterial community structures. The exudates chosen were detected in natural maize exudates (glu

Effect of soil compaction on photosynthesis and carbon partitioning within a maize–soil system

Autor: Ashraf Tubeileh, Sylvain Plantureux, Armand Guckert, Virginie Groleau-Renaud

Publikováno v: Soil and Tillage Research. 71:151-161

Soil compaction is known to affect plant growth. However, most of the information regarding the effects of this factor on carbon partitioning has been obtained on young plants while little is known about the evolution of these effects with plant age.

MOBILIZATION OF LABELLED ORGANIC SULFUR IN RHIZOSPHERE OF RAPE AND BARLEY AND IN NON-RHIZOSPHERE SOIL

Publikováno v: Journal of Plant Nutrition
Journal of Plant Nutrition, Taylor & Francis, 2002, 25 (10), pp.2191-2204

Rape is known to require more sulfur (S) than is necessary for the secondary metabolite synthesis. It is hypothesized that its coarse root system harbors more homogenous microbial biomass specific for sulfur immobilization/remobilization. In a growth

Impact of growth stage on the bacterial community structure along maize roots, as determined by metabolic and genetic fingerprinting

Autor: Armand Guckert, Ezékiel Baudoin, Emile Benizri

Publikováno v: Applied Soil Ecology. 19:135-145

Metabolic and genetic profiles were used to determine whether spatial and temporal variations in rhizodeposition along maize roots coincide with different bacterial community structures. Bacterial communities were extracted from the bulk soil and adh

Root Colonization by Inoculated Plant Growth-Promoting Rhizobacteria

Autor: Emile Benizri, Armand Guckert, Ezékiel Baudoin

Publikováno v: Biocontrol Science and Technology. 11:557-574

Certain rhizobacteria referred to as 'plant growth-promoting rhizobacteria' (PGPR) can contribute to the biological control of plant pathogens and improve plant growth. They enhance root development either directly by producing phytohormones, or indi
