Overview

What is he best known for?

The fields of study he is best known for:

  • Botany
  • Ecology
  • Bacteria

Bernard Dreyfus spends much of his time researching Botany, Bradyrhizobium, Root nodule, Rhizobia and Azorhizobium. His research in Botany intersects with topics in Mesorhizobium, Bradyrhizobium japonicum, 16S ribosomal RNA, Sinorhizobium and Rhizobium. In his study, which falls under the umbrella issue of Rhizobium, Azorhizobium caulinodans, Sesbania rostrata and Sesbania is strongly linked to Rhizobium galegae.

He works mostly in the field of Bradyrhizobium, limiting it down to concerns involving Proteobacteria and, occasionally, Burkholderia, Dalbergia and Methylobacterium radiotolerans. His Root nodule research is multidisciplinary, relying on both Aeschynomene and Rhizobacteria. His Rhizobia research incorporates elements of Oryza, Oryza glaberrima, Oryza sativa and Rhizobiaceae.

His most cited work include:

  • Legumes Symbioses: Absence of Nod Genes in Photosynthetic Bradyrhizobia (465 citations)
  • Methylotrophic Methylobacterium bacteria nodulate and fix nitrogen in symbiosis with legumes. (414 citations)
  • Characterization of Azorhizobium caulinodans gen. nov., sp. nov., a stem-nodulating nitrogen-fixing bacterium isolated from Sesbania rostrata (373 citations)

What are the main themes of his work throughout his whole career to date?

His main research concerns Botany, Rhizobia, Nitrogen fixation, Bradyrhizobium and Symbiosis. His biological study spans a wide range of topics, including Rhizobiaceae, Rhizobium and Root nodule. His work on Nod factor as part of general Rhizobia research is often related to Sustainable management and Beneficial use, thus linking different fields of science.

His study on Nitrogen fixation also encompasses disciplines like

  • Agronomy, which have a strong connection to Soil water and Rhizosphere,
  • Microbiology that intertwine with fields like Sesbania and Bacteria. His research integrates issues of Aeschynomene, Bradyrhizobium japonicum, 16S ribosomal RNA and Fabaceae in his study of Bradyrhizobium. His Azorhizobium study combines topics in areas such as Sinorhizobium and Rhizobium galegae.

He most often published in these fields:

  • Botany (61.11%)
  • Rhizobia (25.93%)
  • Nitrogen fixation (24.07%)

What were the highlights of his more recent work (between 2007-2020)?

  • Botany (61.11%)
  • Rhizobia (25.93%)
  • Ecology (9.26%)

In recent papers he was focusing on the following fields of study:

Bernard Dreyfus mainly focuses on Botany, Rhizobia, Ecology, Acacia and Symbiosis. His Botany research includes elements of Bradyrhizobium, Phylogenetic tree, Pisolithus, Mycorrhiza and Root nodule. The study incorporates disciplines such as Officinalis, Bradyrhizobium japonicum, Host and Pterocarpus in addition to Bradyrhizobium.

His work deals with themes such as Natural resource and Domestication, which intersect with Rhizobia. His study looks at the intersection of Symbiosis and topics like Nitrogen fixation with Root hair, Crotalaria, Rhizobium and Acacia auriculiformis. His Methylobacterium study incorporates themes from Fabaceae and Rhizobiaceae.

Between 2007 and 2020, his most popular works were:

  • Multi-host ectomycorrhizal fungi are predominant in a Guinean tropical rainforest and shared between canopy trees and seedlings. (52 citations)
  • Nurse shrubs increased the early growth of Cupressus seedlings by enhancing belowground mutualism and soil microbial activity (38 citations)
  • The Exotic Legume Tree Species Acacia holosericea Alters Microbial Soil Functionalities and the Structure of the Arbuscular Mycorrhizal Community (34 citations)

In his most recent research, the most cited papers focused on:

  • Botany
  • Ecology
  • Bacteria

Bernard Dreyfus mainly investigates Botany, Rhizobia, Pisolithus, Root nodule and Mycorrhiza. Bernard Dreyfus studies Biofertilizer which is a part of Botany. His Rhizobia research incorporates themes from Aeschynomene, Bradyrhizobium and Phylogenetic tree.

The various areas that Bernard Dreyfus examines in his Pisolithus study include Soil classification, Mycorrhizosphere, Phosphate solubilizing bacteria and Soil conditioner. His work deals with themes such as Rhizobacteria and Rhizobium leguminosarum, which intersect with Root nodule. His work carried out in the field of Mycorrhiza brings together such families of science as Acacia, Acacia holosericea, Resistance, Rhizosphere and Soil microbiology.
