Overview

What is he best known for?

The fields of study he is best known for:

  • Botany
  • Ecology
  • Bacteria

Botany, Mycorrhiza, Citrus canker, Horticulture and Rutaceae are his primary areas of study. His study ties his expertise on Candidatus Liberibacter together with the subject of Botany. His study on Mycorrhiza is covered under Symbiosis.

His studies deal with areas such as Canker, Xanthomonas citri and Cultivar as well as Citrus canker. His Rutaceae research integrates issues from Rootstock, Trifoliate orange and Orange. His study looks at the intersection of Rootstock and topics like Transpiration with Agronomy.

His most cited work include:

  • Functioning of mycorrhizal associations along the mutualism–parasitism continuum* (1420 citations)
  • Growth Depression in Mycorrhizal Citrus at High-Phosphorus Supply (Analysis of Carbon Costs) (314 citations)
  • Xanthomonas axonopodis pv. citri: factors affecting successful eradication of citrus canker. (303 citations)

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

His primary scientific interests are in Horticulture, Botany, Citrus canker, Xanthomonas citri and Agronomy. His Botany study frequently links to adjacent areas such as Inoculation. His Citrus canker study combines topics in areas such as Plant disease resistance, Cultivar, Xanthomonas axonopodis, Canker and Genome.

His study in Agronomy is interdisciplinary in nature, drawing from both Nutrient, Soil water, Mycorrhiza and Transpiration. His Mycorrhiza study integrates concerns from other disciplines, such as Glomus and Shoot. His Rutaceae research is multidisciplinary, relying on both Citrus fruit, Trifoliate orange, Phycomycetes and Xanthomonas campestris.

He most often published in these fields:

  • Horticulture (42.41%)
  • Botany (39.79%)
  • Citrus canker (32.46%)

What were the highlights of his more recent work (between 2016-2021)?

  • Horticulture (42.41%)
  • Citrus canker (32.46%)
  • Xanthomonas citri (23.56%)

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

His primary areas of investigation include Horticulture, Citrus canker, Xanthomonas citri, Plant disease resistance and Pathogen. His work carried out in the field of Citrus canker brings together such families of science as Phytotoxicity and Canker. His research integrates issues of Extracellular, Order Xanthomonadales, Genus Xanthomonas and Orange in his study of Xanthomonas citri.

His Plant disease resistance research includes themes of Citrus paradisi and Nuclear gene. He has researched Pathogen in several fields, including Rootstock, Phytophthora nicotianae, Inoculation, Phytosanitary certification and Citrus fruit. Genetics and Botany are commonly linked in his work.

Between 2016 and 2021, his most popular works were:

  • Little evidence that farmers should consider abundance or diversity of arbuscular mycorrhizal fungi when managing crops. (86 citations)
  • Recent advances in the understanding of Xanthomonas citri ssp. citri pathogenesis and citrus canker disease management. (40 citations)
  • Tale of the Huanglongbing Disease Pyramid in the Context of the Citrus Microbiome (24 citations)

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

  • Botany
  • Ecology
  • Bacteria

His primary areas of study are Horticulture, Citrus canker, Plant disease resistance, Agriculture and Agroforestry. His Horticulture study incorporates themes from Genetically modified crops and Protoplast. His Citrus canker research integrates issues from Phylum Proteobacteria, Xanthomonas citri, Transformation and Orange.

The concepts of his Xanthomonas citri study are interwoven with issues in Genome, Nuclear gene and Citrus paradisi. His work carried out in the field of Agriculture brings together such families of science as Community structure, Arbuscular mycorrhizal symbiosis and Crop. James H. Graham interconnects Crop yield, Yield, Colonisation and Sustainability in the investigation of issues within Agroforestry.
