Overview

What is he best known for?

The fields of study he is best known for:

  • Gene
  • Botany
  • DNA

Domestication, Genetics, Ploidy, Genetic variation and Genome are his primary areas of study. Hakan Özkan has researched Domestication in several fields, including Genetic similarity, Amplified fragment length polymorphism, Genetic diversity, Germplasm and Agriculture. Hakan Özkan studies Haplotype which is a part of Genetics.

The Ploidy study combines topics in areas such as Molecular biology, DNA, DNA profiling and DNA methylation. The study incorporates disciplines such as Evolutionary biology, Zinc, Plant breeding, Micronutrient and Genetic divergence in addition to Genetic variation. His work carried out in the field of Genome brings together such families of science as Chromosome and Locus.

His most cited work include:

  • Sequence elimination and cytosine methylation are rapid and reproducible responses of the genome to wide hybridization and allopolyploidy in wheat (601 citations)
  • Allopolyploidy-Induced Rapid Genome Evolution in the Wheat (Aegilops–Triticum) Group (551 citations)
  • Genetics and geography of wild cereal domestication in the near east (516 citations)

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

Hakan Özkan mainly investigates Botany, Genetics, Genetic diversity, Domestication and Agronomy. Hakan Özkan usually deals with Botany and limits it to topics linked to Amplified fragment length polymorphism and Phylogenetics and Phylogenetic tree. His study in Genome, Ploidy, Allele, Polyploid and Haplotype is done as part of Genetics.

His research in Genetic diversity intersects with topics in Biotechnology, Germplasm and Genetic variation. His research investigates the connection between Domestication and topics such as Evolutionary biology that intersect with issues in Population genetics and Introgression. His Agronomy research focuses on subjects like Zinc, which are linked to Shoot.

He most often published in these fields:

  • Botany (25.52%)
  • Genetics (24.14%)
  • Genetic diversity (22.07%)

What were the highlights of his more recent work (between 2018-2021)?

  • Domestication (19.31%)
  • Food science (7.59%)
  • Evolutionary biology (10.34%)

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

Hakan Özkan focuses on Domestication, Food science, Evolutionary biology, Allele and Genome. His study in Domestication is interdisciplinary in nature, drawing from both Agriculture, Directional selection, Plant breeding, Host and Gene. The concepts of his Evolutionary biology study are interwoven with issues in Adaptation, Range and Genetic diversity.

To a larger extent, Hakan Özkan studies Genetics with the aim of understanding Allele. Genetics is closely attributed to Amplified fragment length polymorphism in his work. His biological study spans a wide range of topics, including Chromosome, Introgression, Secale and Sequence assembly.

Between 2018 and 2021, his most popular works were:

  • Durum wheat genome highlights past domestication signatures and future improvement targets (180 citations)
  • Tracing the ancestry of modern bread wheats (67 citations)
  • Exome sequences and multi-environment field trials elucidate the genetic basis of adaptation in barley. (16 citations)

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

  • Gene
  • Botany
  • DNA

His primary areas of study are Domestication, Evolutionary biology, Genome, Adaptation and Genetic variation. His work in Domestication addresses issues such as Genetic diversity, which are connected to fields such as Life history theory. His Evolutionary biology research incorporates elements of Mutation, Gene, Wild emmer wheat and Haplotype.

His research on Genome concerns the broader Genetics. His work on Triticeae, Triticale and Chromosome as part of general Genetics research is frequently linked to Retrotransposon, bridging the gap between disciplines. His Genetic variation research is multidisciplinary, relying on both Genetic divergence, Synteny, Locus and Plant breeding.
