Overview

What is he best known for?

The fields of study he is best known for:

  • Gene
  • Botany
  • Enzyme

The scientist’s investigation covers issues in Botany, Endophyte, Festuca arundinacea, Epichloë and Acremonium. He works in the field of Botany, namely Lolium. His research in Endophyte intersects with topics in Aphid and Festuca.

His research integrates issues of Epichloe typhina, Seed treatment, Pyrrolizidine and Epichloë coenophiala in his study of Festuca arundinacea. His Epichloë research incorporates elements of Nucleic acid sequence, Gene, Agronomy and Neotyphodium. His Acremonium research incorporates themes from Fungi imperfecti and Parasitism.

His most cited work include:

  • Fungal endophyte-infected grasses: Alkaloid accumulation and aphid response. (336 citations)
  • Fungal Endophytes of Grasses (240 citations)
  • Evolutionary diversification of fungal endophytes of tall fescue grass by hybridization with Epichloë species (227 citations)

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

Malcolm R. Siegel mainly investigates Botany, Endophyte, Acremonium, Animal science and Festuca arundinacea. His work deals with themes such as Epichloë and Nicotiana tabacum, which intersect with Botany. His Endophyte research integrates issues from Perennial plant, Aphid, Poaceae, Agronomy and Host.

His Acremonium research includes themes of Weight gain, Fungi imperfecti, Toxicity, Festuca arizonica and Lolium perenne. His Animal science research is multidisciplinary, incorporating perspectives in Acremonium coenophialum, Rodent, Endocrinology and Reproduction. His Festuca arundinacea study combines topics in areas such as Protoplast, Pyrrolizidine, Epichloë coenophiala and Fungicide.

He most often published in these fields:

  • Botany (60.00%)
  • Endophyte (47.14%)
  • Acremonium (30.00%)

What were the highlights of his more recent work (between 1993-2018)?

  • Botany (60.00%)
  • Epichloë (15.71%)
  • Endophyte (47.14%)

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

Botany, Epichloë, Endophyte, Festuca and Host are his primary areas of study. His study in the fields of Acremonium and Fungal endophyte under the domain of Botany overlaps with other disciplines such as Ergot alkaloid. Malcolm R. Siegel has included themes like Genus, Agronomy and Neotyphodium in his Epichloë study.

His Endophyte research is multidisciplinary, incorporating elements of Genetics, Alkaloid, Animal science and Festuca arundinacea. His work in Festuca addresses subjects such as Lolium, which are connected to disciplines such as Aphid and Loline alkaloid. Malcolm R. Siegel interconnects Perennial plant, Inoculation, Inflorescence, Poaceae and Seedling in the investigation of issues within Host.

Between 1993 and 2018, his most popular works were:

  • Evolutionary diversification of fungal endophytes of tall fescue grass by hybridization with Epichloë species (227 citations)
  • Contribution of Fungal Loline Alkaloids to Protection from Aphids in a Grass-Endophyte Mutualism (208 citations)
  • Sexual compatibility and taxonomy of a new species of Epichloe symbiotic with fine fescue grasses (155 citations)

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

  • Gene
  • Botany
  • Enzyme

Malcolm R. Siegel mostly deals with Epichloë, Botany, Neotyphodium, Endophyte and Epichloe festucae. The various areas that Malcolm R. Siegel examines in his Epichloë study include Lolium and Festuca arundinacea. His Lolium research integrates issues from Aphid, Festuca and Loline alkaloid.

Malcolm R. Siegel has researched Festuca arundinacea in several fields, including Ascomycota and Phylogenetic tree. His research in Epichloe festucae intersects with topics in Acremonium and Agronomy, Festuca rubra.
