Overview

What is he best known for?

The fields of study he is best known for:

  • Botany
  • Ecology
  • Enzyme

Iver Jakobsen mainly investigates Botany, Mycorrhiza, Symbiosis, Hypha and Phycomycetes. His work carried out in the field of Botany brings together such families of science as Agronomy, Rhizobacteria, Phosphate and Solanaceae. He has researched Mycorrhiza in several fields, including Solanum, Soil water, Glomus, Arbuscular mycorrhiza and Mycelium.

His study on Symbiosis is mostly dedicated to connecting different topics, such as Shoot. His Hypha research integrates issues from Linum and Arbuscular mycorrhizal fungi. He combines subjects such as Cucumis and Fungus with his study of Phycomycetes.

His most cited work include:

  • External hyphae of vesicular arbuscular mycorrhizal fungi associated with trifolium subterraneum l. 1. spread of hyphae and phosphorus inflow into roots (738 citations)
  • Mycorrhizal fungi can dominate phosphate supply to plants irrespective of growth responses. (656 citations)
  • Roles of Arbuscular Mycorrhizas in Plant Phosphorus Nutrition: Interactions between Pathways of Phosphorus Uptake in Arbuscular Mycorrhizal Roots Have Important Implications for Understanding and Manipulating Plant Phosphorus Acquisition (616 citations)

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

Iver Jakobsen mostly deals with Botany, Mycorrhiza, Hypha, Symbiosis and Agronomy. Botany and Phosphate are commonly linked in his work. In his research, Dry weight is intimately related to Phycomycetes, which falls under the overarching field of Mycorrhiza.

His Hypha research incorporates elements of Arbuscular mycorrhizal fungi, Cucumis, Fungicide and Rhizosphere. His research in Symbiosis intersects with topics in Inoculation, Host and Sativum. His studies in Agronomy integrate themes in fields like Phytoremediation, Plant nutrition, Nutrient and Soil fertility.

He most often published in these fields:

  • Botany (60.73%)
  • Mycorrhiza (45.55%)
  • Hypha (37.70%)

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

  • Botany (60.73%)
  • Hypha (37.70%)
  • Agronomy (26.70%)

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

His main research concerns Botany, Hypha, Agronomy, Shoot and Inoculation. His work on Mycelium as part of general Botany research is often related to Composition, thus linking different fields of science. His Mycelium study frequently links to other fields, such as Mycorrhiza.

His Hypha research integrates issues from Rhizophagus irregularis, Wild type, Symbiosis and Fungus. The study incorporates disciplines such as Sludge, Nutrient, Soil phosphorus and Biochar in addition to Agronomy. The various areas that Iver Jakobsen examines in his Shoot study include Transporter, Mutant, Phosphate and Microbial inoculant.

Between 2013 and 2021, his most popular works were:

  • A mycorrhizal fungus grows on biochar and captures phosphorus from its surfaces (120 citations)
  • Phosphorus acquisition efficiency in arbuscular mycorrhizal maize is correlated with the abundance of root-external hyphae and the accumulation of transcripts encoding PHT1 phosphate transporters. (114 citations)
  • Phosphorus acquisition efficiency in arbuscular mycorrhizal maize is correlated with the abundance of root-external hyphae and the accumulation of transcripts encoding PHT1 phosphate transporters. (114 citations)

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

  • Ecology
  • Botany
  • Enzyme

His primary areas of study are Botany, Agronomy, Shoot, Hypha and Nutrient. Iver Jakobsen interconnects Medicago truncatula and Gene in the investigation of issues within Botany. He focuses mostly in the field of Agronomy, narrowing it down to topics relating to Biochar and, in certain cases, Soil fertility, Diffusive gradients in thin films, Sludge and Extraction.

His study in Hypha is interdisciplinary in nature, drawing from both Transporter, Colonization, Wild type, Mutant and Symbiosis. His Symbiosis study combines topics in areas such as Fungal Structures, Inoculation, Host and Phosphate. He has researched Nutrient in several fields, including Rhizophagus irregularis, Soil microbiology, Mycorrhiza and Mycelium.
