  • 2007 - Fellow of the American Phytopathological Society

Overview

What is he best known for?

The fields of study he is best known for:

  • Botany
  • Gene
  • Enzyme

Raymond Hammerschmidt mainly focuses on Inoculation, Microbiology, Botany, Peroxidase and Biochemistry. His work carried out in the field of Inoculation brings together such families of science as Cultivar, Systemic acquired resistance, Lignin, Cucurbitaceae and Cell wall. Raymond Hammerschmidt combines subjects such as Plant disease resistance and Solanaceae with his study of Microbiology.

His Botany research integrates issues from Microorganism, Cladosporium cucumerinum, Agrobacterium and Horticulture. He works mostly in the field of Peroxidase, limiting it down to topics relating to Polyacrylamide gel electrophoresis and, in certain cases, Isozyme, Colletotrichum lagenarium, Citrullus lanatus and Specific activity. Raymond Hammerschmidt studies Biochemistry, namely Phenylalanine ammonia-lyase.

His most cited work include:

  • Phenolic Compounds and Their Role in Disease Resistance (1055 citations)
  • Association of enhanced peroxidase activity with induced systemic resistance of cucumber to Colletotrichum lagenarium (885 citations)
  • PHYTOALEXINS: What Have We Learned After 60 Years? (455 citations)

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

Raymond Hammerschmidt spends much of his time researching Botany, Horticulture, Microbiology, Agronomy and Cultivar. The concepts of his Botany study are interwoven with issues in Peroxidase, Inoculation, Wax and Solanaceae. His Inoculation research includes themes of Lignin, Cell wall and Cucurbitaceae.

His work deals with themes such as Plant disease resistance and Mutant, which intersect with Microbiology. His Plant disease resistance study is concerned with Biochemistry in general. His Cultivar research includes elements of Blight and Phytophthora infestans.

He most often published in these fields:

  • Botany (25.75%)
  • Horticulture (20.36%)
  • Microbiology (16.17%)

What were the highlights of his more recent work (between 2011-2021)?

  • Horticulture (20.36%)
  • Agronomy (14.97%)
  • Botany (25.75%)

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

The scientist’s investigation covers issues in Horticulture, Agronomy, Botany, Glyphosate and Prunus. His work on Age-related resistance, Phytophthora capsici and Inoculation as part of general Horticulture research is frequently linked to WINTER SQUASH, bridging the gap between disciplines. His study in Inoculation is interdisciplinary in nature, drawing from both Host, Oomycete and Callus.

His Crop, Yield, Downy mildew and Phakopsora pachyrhizi study in the realm of Agronomy connects with subjects such as Distribution. His study connects Peroxidase and Botany. He focuses mostly in the field of Prunus, narrowing it down to topics relating to Armillaria root rot and, in certain cases, Root disease, Fungus and Microbiology.

Between 2011 and 2021, his most popular works were:

  • Glyphosate Effects on Plant Mineral Nutrition, Crop Rhizosphere Microbiota, and Plant Disease in Glyphosate-Resistant Crops (131 citations)
  • Mechanistic study on uptake and transport of pharmaceuticals in lettuce from water. (30 citations)
  • A Coordinated Effort to Manage Soybean Rust in North America: A Success Story in Soybean Disease Monitoring. (26 citations)

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

  • Botany
  • Gene
  • Enzyme

His primary scientific interests are in Agronomy, Crop, Glyphosate, Shoot and Biochemistry. His Agronomy research incorporates elements of Shikimic acid and Plant defense against herbivory. Raymond Hammerschmidt interconnects Soybean rust, Fusarium, Phakopsora pachyrhizi and Downy mildew in the investigation of issues within Crop.

His Glyphosate research is multidisciplinary, incorporating elements of Rhizosphere, Fungicide and Rhizoctonia. He has included themes like Chromatography, Aqueous solution and Metabolism in his Shoot study. Much of his study explores Biochemistry relationship to Chlorogenic acid.
