  • Microbial Products Trigger Amino Acid Exudation from Plant Roots (204 citations)

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

The scientist’s investigation covers issues in Botany, Rhizobium, Root nodule, Agronomy and Nitrogen fixation. His work carried out in the field of Botany brings together such families of science as Biochemistry, Rhizosphere, Bacteria and Rhizobiaceae, Rhizobium leguminosarum. Donald A. Phillips has researched Rhizobium in several fields, including Nod, Rhizobia, Symbiosis, Luteolin and Medicago sativa.

His study in Root nodule is interdisciplinary in nature, drawing from both Shoot, Horticulture, Plant physiology, Respiration and Nitrogenase. His Agronomy study incorporates themes from N2 Fixation and Animal science. His work investigates the relationship between Nitrogen fixation and topics such as Photosynthesis that intersect with problems in Dry weight.

Donald A. Phillips mainly focuses on Botany, Rhizosphere, Biochemistry, Bacteria and Rhizobium. His Botany research is multidisciplinary, incorporating perspectives in Yield and Root nodule. The Root nodule study combines topics in areas such as Rhizobiaceae and Respiration.

Donald A. Phillips interconnects Ecology, Soil water, Nutrient, Microorganism and Shoot in the investigation of issues within Rhizosphere. Donald A. Phillips combines subjects such as Pesticide and Microbiology with his study of Bacteria. In his work, Root hair is strongly intertwined with Symbiosis, which is a subfield of Rhizobium.

Between 1995 and 2015, his most popular works were:

  • Root exudates as mediators of mineral acquisition in low-nutrient environments (908 citations)
  • Diverse functions of isoflavonoids in legumes transcend anti-microbial definitions of phytoalexins (226 citations)
  • Microbial Products Trigger Amino Acid Exudation from Plant Roots (204 citations)

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

  • Botany
  • Bacteria
  • Gene

Donald A. Phillips focuses on Botany, Biochemistry, Rhizosphere, Efflux and Isoflavonoid. Many of his research projects under Botany are closely connected to Inorganic ions with Inorganic ions, tying the diverse disciplines of science together. His research in the fields of Electrophoretic mobility shift assay overlaps with other disciplines such as Trans-Activators, Homoserine and Flavin group.

His biological study spans a wide range of topics, including Soil water, Plant physiology, Root nodule, Rhizobiaceae and Shoot. His Efflux research is multidisciplinary, incorporating perspectives in Amino acid, Medicago truncatula, Soil food web and Poaceae. His Isoflavonoid research includes elements of Genetics, Symbiosis, Antimicrobial and Rhizobium.
