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.
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.
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.
