Overview

What is he best known for?

The fields of study he is best known for:

  • Botany
  • Fungus
  • Genetics

His main research concerns Phylogenetic tree, Genetics, Phylogenetics, Botany and Fusarium. His work focuses on many connections between Phylogenetic tree and other disciplines, such as Nectriaceae, that overlap with his field of interest in Genus and Nectria. His study brings together the fields of Genetic diversity and Genetics.

The Phylogenetics study combines topics in areas such as Locus, Nuclear gene and DNA sequencing. In most of his Botany studies, his work intersects topics such as Species complex. The concepts of his Fusarium study are interwoven with issues in Contact lens, Fusarium solani and Fusarium oxysporum.

His most cited work include:

  • Reconstructing the early evolution of Fungi using a six-gene phylogeny (1413 citations)
  • Two divergent intragenomic rDNA ITS2 types within a monophyletic lineage of the fungus Fusarium are nonorthologous (1225 citations)
  • Multiple evolutionary origins of the fungus causing Panama disease of banana: Concordant evidence from nuclear and mitochondrial gene genealogies (1096 citations)

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

His scientific interests lie mostly in Fusarium, Botany, Phylogenetic tree, Genetics and Phylogenetics. The various areas that he examines in his Fusarium study include Taxonomy, Mycotoxin, Species complex and Microbiology. His Botany research incorporates themes from Pathogen and Molecular phylogenetics.

His research in Phylogenetic tree intersects with topics in Ribosomal RNA, DNA sequencing and Genetic diversity. His work on Gene, Ribosomal DNA, Genetic variation and Sequence analysis as part of general Genetics research is often related to Fungal genetics, thus linking different fields of science. Much of his study explores Phylogenetics relationship to Intergenic region.

He most often published in these fields:

  • Fusarium (50.00%)
  • Botany (48.90%)
  • Phylogenetic tree (31.32%)

What were the highlights of his more recent work (between 2013-2021)?

  • Fusarium (50.00%)
  • Botany (48.90%)
  • Species complex (18.68%)

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

Kerry O'Donnell mainly focuses on Fusarium, Botany, Species complex, Clade and Genetics. His Fusarium study combines topics in areas such as Taxonomy, Pathogen and Phylogenetic tree. His Phylogenetic tree study integrates concerns from other disciplines, such as Ribosomal RNA, DNA sequencing and Genetic diversity.

His work carried out in the field of Botany brings together such families of science as Heterothallic and Molecular phylogenetics. His Species complex research focuses on subjects like Canker, which are linked to Torreya and Torreya taxifolia. Phylogenetics covers Kerry O'Donnell research in Clade.

Between 2013 and 2021, his most popular works were:

  • A phylum-level phylogenetic classification of zygomycete fungi based on genome-scale data (522 citations)
  • Sequence-based classification and identification of Fungi (106 citations)
  • DNA sequence-based identification of Fusarium : Current status and future directions (102 citations)

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

  • Botany
  • Fungus
  • Genus

His primary areas of study are Fusarium, Botany, Trichothecene, Ecology and Genetics. His Fusarium research incorporates elements of Fungus, Hyaline, Species complex and Genetic diversity. His research on Species complex concerns the broader Phylogenetic tree.

His research in Phylogenetic tree is mostly concerned with Clade. His Agapanthus study in the realm of Botany interacts with subjects such as Northern italy. His Trichothecene study also includes fields such as

  • Fumonisin that connect with fields like Moniliformin, Beauvericin, Molecular phylogenetics and Species diversity,
  • Genetic structure which connect with Fusarium culmorum, Population genetics and Biological dispersal,
  • Veterinary medicine and related Phylogenetics.
