Overview

What is he best known for?

The fields of study he is best known for:

  • Botany
  • Gene
  • Fungus

His primary areas of investigation include Mycosphaerella graminicola, Graminicola, Botany, Genetics and Septoria. His studies deal with areas such as Disease management, Phaeosphaeria nodorum, Pathosystem and Population genetics as well as Mycosphaerella graminicola. His Graminicola research includes themes of Fungal genetics, Epoxiconazole and Ascospore.

In Fungal genetics, John A. Lucas works on issues like Virulence, which are connected to Pathogen. His Botany research is multidisciplinary, incorporating perspectives in Stagonospora, Abscisic acid, Transformation and Microbiology. The various areas that John A. Lucas examines in his Septoria study include Strobilurin, Fungicide, Conidium and Spore.

His most cited work include:

  • Analysis of Two in Planta Expressed LysM Effector Homologs from the Fungus Mycosphaerella graminicola Reveals Novel Functional Properties and Varying Contributions to Virulence on Wheat (222 citations)
  • Role of Ascospores in Further Spread of QoI-Resistant Cytochrome b Alleles (G143A) in Field Populations of Mycosphaerella graminicola. (188 citations)
  • The evolution of fungicide resistance. (168 citations)

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

The scientist’s investigation covers issues in Botany, Fungicide, Microbiology, Genetics and Horticulture. His work focuses on many connections between Botany and other disciplines, such as Pathogen, that overlap with his field of interest in Eyespot. His work is dedicated to discovering how Fungicide, Biotechnology are connected with Crop protection and other disciplines.

In most of his Microbiology studies, his work intersects topics such as Mutant. His Genetics study which covers RAPD that intersects with Pyrenophora teres. His Mycosphaerella graminicola research is multidisciplinary, incorporating elements of Triazole and Epoxiconazole.

He most often published in these fields:

  • Botany (36.11%)
  • Fungicide (21.11%)
  • Microbiology (19.44%)

What were the highlights of his more recent work (between 2007-2021)?

  • Botany (36.11%)
  • Mycosphaerella graminicola (14.44%)
  • Horticulture (15.56%)

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

His main research concerns Botany, Mycosphaerella graminicola, Horticulture, Fungicide and Genetics. John A. Lucas interconnects Plant disease resistance, 16S ribosomal RNA and Phytoplasma in the investigation of issues within Botany. He works mostly in the field of Mycosphaerella graminicola, limiting it down to concerns involving Graminicola and, occasionally, Mutant, Fungal genetics and Epoxiconazole.

As a part of the same scientific family, he mostly works in the field of Horticulture, focusing on Agronomy and, on occasion, Molecular diagnostics. His Fungicide research includes themes of Carbamate, Blumeria graminis, Septoria and Resistance. He has included themes like Disease and Mycosphaerella in his Genetics study.

Between 2007 and 2021, his most popular works were:

  • Analysis of Two in Planta Expressed LysM Effector Homologs from the Fungus Mycosphaerella graminicola Reveals Novel Functional Properties and Varying Contributions to Virulence on Wheat (222 citations)
  • The evolution of fungicide resistance. (168 citations)
  • Risk assessment studies on succinate dehydrogenase inhibitors, the new weapons in the battle to control Septoria leaf blotch in wheat (101 citations)

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

  • Gene
  • Botany
  • Fungus

John A. Lucas mostly deals with Graminicola, Mycosphaerella graminicola, Botany, Genetics and Microbiology. His biological study spans a wide range of topics, including Fungal genetics, Epoxiconazole and Mutant. The concepts of his Botany study are interwoven with issues in Relative species abundance, Phytoplasma, 16S ribosomal RNA, Horticulture and Veterinary medicine.

The Horticulture study combines topics in areas such as Ascospore, Spore, Eyespot and Species diversity. His Microbiology research incorporates themes from Plant disease resistance, Plant defense against herbivory, Ergosterol and Virulence. As a member of one scientific family, John A. Lucas mostly works in the field of Biochemistry, focusing on Septoria and, on occasion, Powdery mildew.
