Overview

What is he best known for?

The fields of study he is best known for:

  • Botany
  • Bacteria
  • Enzyme

His primary scientific interests are in Botany, Root nodule, Frankia, Actinorhizal plant and Biochemistry. Many of his research projects under Botany are closely connected to Lateral root with Lateral root, tying the diverse disciplines of science together. The Root nodule study combines topics in areas such as Endophyte and Casuarina.

His Frankia study combines topics in areas such as Casuarina glauca, Nitrogenase and Frankia alni. His Actinorhizal plant research incorporates themes from Host and Microbiology. His Comptonia peregrina research integrates issues from Myricaceae and Spore.

His most cited work include:

  • The development and function of roots. (354 citations)
  • Isolation and Cultivation in vitro of the Actinomycete Causing Root Nodulation in Comptonia (329 citations)
  • The structural basis for infection of root hairs of Trifolium repens by Rhizobium (184 citations)

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

John G. Torrey focuses on Botany, Frankia, Root nodule, Auxin and Cell biology. John G. Torrey studies Meristem which is a part of Botany. His Frankia study integrates concerns from other disciplines, such as Casuarinaceae, Nitrogenase and Microbiology, Spore.

His Root nodule research also works with subjects such as

  • Endophyte that intertwine with fields like Sporangium,
  • Hypha, which have a strong connection to Ultrastructure. His work on Cytokinin as part of his general Auxin study is frequently connected to Lateral root, thereby bridging the divide between different branches of science. John G. Torrey has researched Cell biology in several fields, including Cellular differentiation, Morphogenesis and Cell division.

He most often published in these fields:

  • Botany (74.85%)
  • Frankia (28.83%)
  • Root nodule (25.77%)

What were the highlights of his more recent work (between 1986-2016)?

  • Botany (74.85%)
  • Frankia (28.83%)
  • Root nodule (25.77%)

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

His primary areas of study are Botany, Frankia, Root nodule, Actinorhizal plant and Symbiosis. His Botany study incorporates themes from Nitrogen fixation, Casuarinaceae and Root hair. His Frankia research is multidisciplinary, incorporating elements of Nitrogenase, Casuarina and Microbiology, Spore.

His Root nodule study combines topics from a wide range of disciplines, such as Endophyte and Hypha. Phosphorus deficiency and Cutting is closely connected to Cluster root in his research, which is encompassed under the umbrella topic of Actinorhizal plant. His study looks at the intersection of Myricaceae and topics like Myrica gale with Comptonia peregrina and Frankiaceae.

Between 1986 and 2016, his most popular works were:

  • Root nodule initiation in Gymnostoma (Casuarinaceae) and Shepherdia (Elaeagnaceae) induced by Frankia strain HFPGpI1 (53 citations)
  • Endophyte sporulation in root nodules of actinorhizal plants (49 citations)
  • Occurrence of cluster roots on Myrica cerifera L. (Myricaceae) in water culture in relation to phosphorus nutrition (46 citations)

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

  • Botany
  • Bacteria
  • Enzyme

His scientific interests lie mostly in Botany, Frankia, Root nodule, Actinorhizal plant and Root system. His study of Myricaceae is a part of Botany. In his research, Host, Microbiology and Myrica gale is intimately related to Inoculation, which falls under the overarching field of Frankia.

John G. Torrey is involved in the study of Root nodule that focuses on Casuarinaceae in particular. His studies examine the connections between Actinorhizal plant and genetics, as well as such issues in Plant nutrition, with regards to Cutting, Phosphorus deficiency and Rhizosphere. John G. Torrey works mostly in the field of Root system, limiting it down to topics relating to Nitrogenase and, in certain cases, Betulaceae and Rugosa.
