Overview

What is he best known for?

The fields of study he is best known for:

  • Gene
  • Botany
  • Bacteria

David G. Barker focuses on Botany, Medicago truncatula, Cell biology, Symbiosis and Rhizobiaceae. David G. Barker interconnects Genetic analysis, Sinorhizobium meliloti and Rhizobium in the investigation of issues within Botany. David G. Barker is involved in the study of Medicago truncatula that focuses on Periarbuscular membrane in particular.

His Cell biology research integrates issues from Nod factor and Gene expression, Gene, Root hair. His Nod factor research is multidisciplinary, incorporating perspectives in Bioassay and Microbiology. His work carried out in the field of Symbiosis brings together such families of science as Genome, Strain, Medicago sativa, Molecular genetics and Transformation.

His most cited work include:

  • Agrobacterium rhizogenes-transformed roots of Medicago truncatula for the study of nitrogen-fixing and endomycorrhizal symbiotic associations. (551 citations)

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

The scientist’s investigation covers issues in Medicago truncatula, Botany, Cell biology, Root hair and Rhizobium. His biological study spans a wide range of topics, including Gene expression, Gene, Rhizobia, Nod factor and Sinorhizobium meliloti. David G. Barker combines subjects such as Symbiosis, Rhizobiaceae, Mutant and Agrobacterium with his study of Botany.

His Cell biology research incorporates elements of Periarbuscular membrane, Hypha and Apoplast. His research investigates the connection between Root hair and topics such as Frankia that intersect with problems in Host. The study incorporates disciplines such as Medicago sativa, Medicago and Root nodule in addition to Rhizobium.

He most often published in these fields:

  • Medicago truncatula (63.49%)
  • Botany (60.32%)
  • Cell biology (41.27%)

What were the highlights of his more recent work (between 2014-2019)?

  • Botany (60.32%)
  • Root hair (33.33%)
  • Actinorhizal plant (12.70%)

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

His primary areas of study are Botany, Root hair, Actinorhizal plant, Symbiosis and Cell biology. His Botany study combines topics in areas such as Medicago truncatula and Mutant. David G. Barker has researched Medicago truncatula in several fields, including Phenotype, Sinorhizobium meliloti, Ca2 signaling and Transcription factor.

His research in Mutant intersects with topics in Rhizobia, Kinase and Root nodule. His Rhizobia research is multidisciplinary, relying on both Cell wall and Rhizobium. In his work, Host, Microbiology and Gene is strongly intertwined with Frankia, which is a subfield of Actinorhizal plant.

Between 2014 and 2019, his most popular works were:

  • Ancestral alliances: Plant mutualistic symbioses with fungi and bacteria (146 citations)
  • Remodeling of the Infection Chamber before Infection Thread Formation Reveals a Two-Step Mechanism for Rhizobial Entry into the Host Legume Root Hair (80 citations)
  • A role for the mevalonate pathway in early plant symbiotic signaling (61 citations)

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

  • Gene
  • Bacteria
  • Genome

His main research concerns Symbiosis, Rhizobia, Cell biology, Medicago truncatula and Mutant. His Symbiosis research incorporates themes from Mutualism, Ecology and Dikarya. The Rhizobia study combines topics in areas such as Cell wall, Sinorhizobium meliloti, Mycotroph and Root hair.

His work deals with themes such as HEK 293 cells, Receptor and Botany, which intersect with Cell biology. His Medicago truncatula research is multidisciplinary, incorporating elements of Gene expression and Kinase.
