Overview

What is he best known for?

The fields of study he is best known for:

  • Botany
  • Ecology
  • Fungus

Marc St-Arnaud mainly focuses on Botany, Rhizosphere, Mycelium, Mycorrhiza and Soil microbiology. His Botany study frequently links to adjacent areas such as Microbiology. His work carried out in the field of Rhizosphere brings together such families of science as Microbiome, Biotechnology, Disease susceptibility, Crop production and Abiotic stress.

His research in Mycelium tackles topics such as Symbiosis which are related to areas like Spore. In his study, Glomeromycota, Salicaceae, Shoot, Salix viminalis and Woody plant is strongly linked to Inoculation, which falls under the umbrella field of Mycorrhiza. The various areas that Marc St-Arnaud examines in his Soil microbiology study include Microorganism and Agronomy.

His most cited work include:

  • Enhanced hyphal growth and spore production of the arbuscular mycorrhizal fungus Glomus intraradices in an in vitro system in the absence of host roots (372 citations)
  • Direct interaction between the arbuscular mycorrhizal fungus Glomus intraradices and different rhizosphere microorganisms (268 citations)
  • Arbuscular mycorrhiza on root-organ cultures (233 citations)

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

Marc St-Arnaud mostly deals with Botany, Rhizosphere, Agronomy, Fungus and Phytoremediation. Marc St-Arnaud works mostly in the field of Botany, limiting it down to topics relating to Soil microbiology and, in certain cases, Microorganism, as a part of the same area of interest. Marc St-Arnaud has researched Rhizosphere in several fields, including Microbiome, Willow, Microbial ecology and Nutrient.

The Agronomy study combines topics in areas such as Soil water and Soil test. He focuses mostly in the field of Phytoremediation, narrowing it down to matters related to Soil contamination and, in some cases, Biodegradation. His studies in Mycelium integrate themes in fields like Glomus, Symbiosis, Mycorrhiza and Hyphal growth.

He most often published in these fields:

  • Botany (71.43%)
  • Rhizosphere (26.67%)
  • Agronomy (23.81%)

What were the highlights of his more recent work (between 2017-2021)?

  • Rhizosphere (26.67%)
  • Agronomy (23.81%)
  • Botany (71.43%)

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

His scientific interests lie mostly in Rhizosphere, Agronomy, Botany, Microbial ecology and Phytoremediation. His study on Root microbiome is often connected to Significant difference as part of broader study in Rhizosphere. He is involved in the study of Botany that focuses on Basidiomycota in particular.

His Microbial ecology course of study focuses on Mesocosm and Microcosm, Microbial population biology, Bioaugmentation and Biotic component. His work deals with themes such as Soil contamination, Soil microbiology, Mineralization and Extreme environment, which intersect with Phytoremediation. His Soil contamination research is multidisciplinary, incorporating perspectives in Abiotic component and Environmental remediation.

Between 2017 and 2021, his most popular works were:

  • Trees, fungi and bacteria: tripartite metatranscriptomics of a root microbiome responding to soil contamination (49 citations)
  • Canola Root-Associated Microbiomes in the Canadian Prairies. (30 citations)
  • Soil contamination alters the willow root and rhizosphere metatranscriptome and the root–rhizosphere interactome (30 citations)

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

  • Botany
  • Ecology
  • Fungus

Marc St-Arnaud mostly deals with Rhizosphere, Root microbiome, Olpidium, Microbial ecology and Phytoremediation. His Rhizosphere study combines topics from a wide range of disciplines, such as Canola, Agronomy, Plant nutrition and Fusarium merismoides. The various areas that Marc St-Arnaud examines in his Root microbiome study include Olpidium virulentus, Olpidium brassicae and Nutrient.

His Microbial ecology research includes themes of Willow, Basidiomycota, Botany and Soil water, Soil microbiology. His work on Salix purpurea as part of general Botany research is frequently linked to Fungal genetics, bridging the gap between disciplines. Abiotic component is closely connected to Soil contamination in his research, which is encompassed under the umbrella topic of Phytoremediation.
