Overview

What is he best known for?

The fields of study he is best known for:

  • Botany
  • Gene
  • Genetics

His primary areas of investigation include Mushroom, Botany, Lentinula, Agaricus bisporus and Food science. Daniel J. Royse combines subjects such as Sawdust, Cottonseed, Inoculation and Animal science with his study of Mushroom. His work on Identification as part of general Botany study is frequently connected to Cytospora cincta, therefore bridging the gap between diverse disciplines of science and establishing a new relationship between them.

Daniel J. Royse focuses mostly in the field of Lentinula, narrowing it down to topics relating to Pleurotus and, in certain cases, Agaricus, Flammulina, Toxicology, Molecular evolution and Lineage. His biological study spans a wide range of topics, including Trichoderma harzianum, Liquid chromatography mass spectroscopy, Chromatography, Ribosomal DNA and Ergothioneine. His study in Food science is interdisciplinary in nature, drawing from both Regulation of gene expression, Biochemistry, Gene expression and Cellulase.

His most cited work include:

  • Ubiquity of lignin-degrading peroxidases among various wood-degrading fungi. (202 citations)
  • A systematic assessment of Morchella using RFLP analysis of the 28S ribosomal RNA gene (125 citations)
  • Current Overview of Mushroom Production in the World (105 citations)

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

His scientific interests lie mostly in Mushroom, Botany, Agaricus bisporus, Food science and Genetics. His study in the fields of Lentinula under the domain of Mushroom overlaps with other disciplines such as Substrate. Botany and Ergothioneine are frequently intertwined in his study.

His research integrates issues of Compost, Trichoderma harzianum, Fungi imperfecti, Microbiology and Trichoderma in his study of Agaricus bisporus. As a part of the same scientific family, Daniel J. Royse mostly works in the field of Food science, focusing on Cellulose and, on occasion, Rumen and Stover. His Nutrient research includes elements of Agronomy, Crop and Animal science.

He most often published in these fields:

  • Mushroom (53.26%)
  • Botany (32.61%)
  • Agaricus bisporus (30.43%)

What were the highlights of his more recent work (between 2007-2017)?

  • Mushroom (53.26%)
  • Agaricus bisporus (30.43%)
  • Botany (32.61%)

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

His primary scientific interests are in Mushroom, Agaricus bisporus, Botany, Compost and Horticulture. To a larger extent, Daniel J. Royse studies Food science with the aim of understanding Mushroom. His Agaricus bisporus research is multidisciplinary, incorporating perspectives in Phenylalanine, Hydrolysis, Hydrolyzed protein, Soy protein and Leucine.

In general Botany, his work in Mycelium and Pleurotus eryngii is often linked to Substrate and Agar linking many areas of study. His research in Compost intersects with topics in Nutrient, Egg white and Crop. His work deals with themes such as Flammulina, Lentinula and Per capita, which intersect with Horticulture.

Between 2007 and 2017, his most popular works were:

  • Current Overview of Mushroom Production in the World (105 citations)
  • A GLOBAL PERSPECTIVE ON THE HIGH FIVE: AGARICUS, PLEUROTUS, LENTINULA, AURICULARIA & FLAMMULINA (57 citations)
  • The influence of spawn type and strain on yield, size and mushroom solids content of Agaricus bisporus produced on non-composted and spent mushroom compost (38 citations)

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

  • Botany
  • Gene
  • Genetics

Pleurotus, Mushroom, Horticulture, Pleurotus eryngii and Botany are his primary areas of study. His Pleurotus research integrates issues from Genetics, Agaricus, Flammulina, Toxicology and Lentinula. His Mushroom research is multidisciplinary, relying on both Sawdust, Spawn, Bran and Compost.

The various areas that Daniel J. Royse examines in his Horticulture study include Basidiomycota and Agaricus bisporus. He has researched Pleurotus eryngii in several fields, including Clade, Phylogenetic tree, Species complex, Monophyly and Phylogenetics. The Biological efficiency research Daniel J. Royse does as part of his general Botany study is frequently linked to other disciplines of science, such as Yield, Substrate, Layer and Casing, therefore creating a link between diverse domains of science.
