Overview

What is he best known for?

The fields of study he is best known for:

  • Botany
  • Fungus
  • Genus

Keith A. Seifert mainly investigates Botany, Genetics, Fusarium, Nomenclature and DNA barcoding. Botany is closely attributed to Microascales in his work. Genetics is a component of his Internal transcribed spacer and Molecular taxonomy studies.

Keith A. Seifert has included themes like Ribosomal RNA, Subgenus, Identification and Intron in his DNA barcoding study. In general Ribosomal RNA study, his work on 18S ribosomal RNA often relates to the realm of Fungal genetics, thereby connecting several areas of interest. His studies in Genus integrate themes in fields like Clade and Aspergillus.

His most cited work include:

  • Nuclear ribosomal internal transcribed spacer (ITS) region as a universal DNA barcode marker for Fungi (2815 citations)
  • Phylogeny, identification and nomenclature of the genus Aspergillus (480 citations)
  • Quantifying microbial communities with 454 pyrosequencing: does read abundance count? (423 citations)

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

Keith A. Seifert spends much of his time researching Botany, Taxonomy, Genus, Phylogenetic tree and Phylogenetics. His study on Botany is mostly dedicated to connecting different topics, such as Internal transcribed spacer. His Internal transcribed spacer research entails a greater understanding of Genetics.

His biological study spans a wide range of topics, including Computational biology and DNA barcoding. His Genus research includes elements of Nomenclature and Chaetosphaeria. His Phylogenetic tree research is multidisciplinary, relying on both Evolutionary biology and Aspergillus.

He most often published in these fields:

  • Botany (62.50%)
  • Taxonomy (17.13%)
  • Genus (16.67%)

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

  • Botany (62.50%)
  • Phylogenetics (14.81%)
  • Genus (16.67%)

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

Keith A. Seifert mostly deals with Botany, Phylogenetics, Genus, Taxonomy and Aspergillus. The study incorporates disciplines such as Leotiomycetes, Phylogenetic tree, Internal transcribed spacer and Ascomycota in addition to Botany. The various areas that Keith A. Seifert examines in his Phylogenetics study include Zoology and Claviceps purpurea.

His study looks at the intersection of Genus and topics like Evolutionary biology with Amplicon, Environmental DNA, Glaucus and Nomenclature. His Taxonomy study integrates concerns from other disciplines, such as Sordariales, Chaetomiaceae and Polyphyly. His research in Aspergillus intersects with topics in Monophyly, Subgenus and Sexual States.

Between 2016 and 2021, his most popular works were:

  • Fungal Planet description sheets: 785–867 (53 citations)
  • Phylogeny of xerophilic aspergilli (subgenus Aspergillus) and taxonomic revision of section Restricti. (29 citations)
  • Phylogeny of xerophilic aspergilli (subgenus Aspergillus) and taxonomic revision of section Restricti. (29 citations)

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

  • Botany
  • Fungus
  • Genus

His primary areas of study are Botany, Aspergillus, Phylogenetic tree, Subgenus and Mycotoxin. Botany and Polyphyly are frequently intertwined in his study. His work on Internal transcribed spacer and Clade as part of general Phylogenetic tree study is frequently linked to Xerophile, bridging the gap between disciplines.

His studies deal with areas such as Aspergillus restrictus, Monophyly, Phylogenetics, Coalescent theory and Aspergillus penicillioides as well as Subgenus. His Mycotoxin research incorporates themes from Aspergillus species, Tillage and Sexual States. His Eucalyptus pilularis study in the realm of Eucalyptus interacts with subjects such as Eugenia capensis, Pittosporum tenuifolium and Olea capensis.
