Overview

What is he best known for?

The fields of study he is best known for:

  • Gene
  • Enzyme
  • Botany

Biochemistry, Botany, Agronomy, Ammonium and Hordeum vulgare are his primary areas of study. His study in the fields of Ecophysiology, Canopy and Chlorophyll under the domain of Botany overlaps with other disciplines such as Mathematics. His Agronomy study integrates concerns from other disciplines, such as Nitrogen fixation and Nitrogen.

His studies deal with areas such as Cell wall and Apoplast as well as Ammonium. His Hordeum vulgare research incorporates elements of Zinc, Phosphorus, Nutrient and Ion transporter. His Aquaporin research is multidisciplinary, relying on both Reactive oxygen species, Membrane, Xenopus and Hydrogen peroxide.

His most cited work include:

  • Specific Aquaporins Facilitate the Diffusion of Hydrogen Peroxide across Membranes (892 citations)
  • Reflectance measurement of canopy biomass and nitrogen status in wheat crops using normalized difference vegetation indices and partial least squares regression (764 citations)
  • Membrane transport of hydrogen peroxide (746 citations)

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

Jan K. Schjoerring spends much of his time researching Botany, Agronomy, Ammonium, Biochemistry and Hordeum vulgare. His Botany research includes elements of Zinc and Horticulture. His Agronomy study combines topics in areas such as Nitrogen fixation, Nitrogen and Canopy.

Jan K. Schjoerring interconnects Apoplast, Ammonia, Shoot, Glutamine synthetase and Nitrate in the investigation of issues within Ammonium. His studies in Shoot integrate themes in fields like Hydroponics, Chlorophyll and Animal science. The concepts of his Hordeum vulgare study are interwoven with issues in Biophysics, Phosphorus, Gene and Plant physiology.

He most often published in these fields:

  • Botany (29.49%)
  • Agronomy (23.50%)
  • Ammonium (22.58%)

What were the highlights of his more recent work (between 2014-2021)?

  • Zinc (9.22%)
  • Biophysics (6.45%)
  • Botany (29.49%)

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

His primary scientific interests are in Zinc, Biophysics, Botany, Hordeum vulgare and Biomass. His Botany study incorporates themes from Nicotianamine, Mutant, Nicotianamine synthase and Phosphorus. His Hordeum vulgare research integrates issues from Thylakoid, Photosystem II, Nutrient and Horticulture.

His Biomass research includes elements of Sugar and Straw, Agronomy. His Photosynthesis study improves the overall literature in Biochemistry. His work on Shoot expands to the thematically related Biochemistry.

Between 2014 and 2021, his most popular works were:

  • Two cytosolic glutamine synthetase isoforms play specific roles for seed germination and seed yield structure in Arabidopsis (54 citations)
  • Molecular speciation and tissue compartmentation of zinc in durum wheat grains with contrasting nutritional status (47 citations)
  • Cytosolic Glutamine Synthetase Gln1;2 Is the Main Isozyme Contributing to GS1 Activity and Can Be Up-Regulated to Relieve Ammonium Toxicity (45 citations)

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

  • Gene
  • Enzyme
  • Botany

His primary areas of investigation include Botany, Arabidopsis, Arabidopsis thaliana, Biophysics and Mutant. In general Botany study, his work on Hydroponics often relates to the realm of Composition, thereby connecting several areas of interest. His Arabidopsis research is included under the broader classification of Biochemistry.

His study in Biochemistry is interdisciplinary in nature, drawing from both Manganese and Shoot. Jan K. Schjoerring works mostly in the field of Biophysics, limiting it down to concerns involving Nicotianamine and, occasionally, Metal and Xylem. He combines subjects such as Glutamine synthetase and Seedling with his study of Mutant.
