Overview

What is he best known for?

The fields of study he is best known for:

  • Enzyme
  • Botany
  • Gene

His primary areas of study are Photosynthesis, Biochemistry, Botany, Alternative oxidase and Chloroplast. The concepts of his Photosynthesis study are interwoven with issues in Wild type, Biophysics, Chloroplast stroma and Sucrose. In the subject of general Biochemistry, his work in Defence mechanisms and Metabolism is often linked to Ammonium and Cyanide, thereby combining diverse domains of study.

As part of one scientific family, Ko Noguchi deals mainly with the area of Botany, narrowing it down to issues related to the Spinach, and often Horticulture. His Alternative oxidase research is multidisciplinary, relying on both Malondialdehyde, Antioxidant and Respiratory chain. The Chloroplast study combines topics in areas such as Mutant and Biosynthesis.

His most cited work include:

  • Interaction between photosynthesis and respiration in illuminated leaves. (235 citations)
  • Temperature acclimation of photosynthesis in spinach leaves: analyses of photosynthetic components and temperature dependencies of photosynthetic partial reactions (196 citations)
  • Up-Regulation of Mitochondrial Alternative Oxidase Concomitant with Chloroplast Over-Reduction by Excess Light (169 citations)

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

Botany, Photosynthesis, Biochemistry, Alternative oxidase and Respiration are his primary areas of study. Ko Noguchi works mostly in the field of Botany, limiting it down to topics relating to Horticulture and, in certain cases, Oryza sativa, as a part of the same area of interest. His work deals with themes such as Biophysics and Chloroplast, which intersect with Photosynthesis.

His work on Arabidopsis thaliana, Primary metabolite, Spinach and Mutant as part of general Biochemistry research is frequently linked to Ammonium, bridging the gap between disciplines. Ko Noguchi has included themes like Electron transport chain, Respiratory chain, Cytochrome c oxidase and Mitochondrial respiratory chain in his Alternative oxidase study. In his research on the topic of Respiration, Substrate and Dehydrogenase is strongly related with Animal science.

He most often published in these fields:

  • Botany (54.10%)
  • Photosynthesis (48.36%)
  • Biochemistry (37.70%)

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

  • Photosynthesis (48.36%)
  • Cell biology (10.66%)
  • Electron transport chain (12.30%)

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

Ko Noguchi spends much of his time researching Photosynthesis, Cell biology, Electron transport chain, Reactive oxygen species and Mitochondrial RNA processing. His Photosynthesis study is concerned with the field of Biochemistry as a whole. When carried out as part of a general Cell biology research project, his work on Mitochondrion and Actin is frequently linked to work in Oligodendrocyte, therefore connecting diverse disciplines of study.

His Mitochondrion research incorporates themes from Arabidopsis and Abiotic stress. His study explores the link between Electron transport chain and topics such as Alternative oxidase that cross with problems in Cytochrome c oxidase, Controlled atmosphere, Lupinus, Phosphorus deficiency and Carboxylate. His Mitochondrial RNA processing study also includes fields such as

  • Fasciation and related RNA editing,
  • Lateral root, which have a strong connection to Cell growth and Pentatricopeptide repeat.

Between 2017 and 2021, his most popular works were:

  • Effects of instantaneous and growth CO2 levels and abscisic acid on stomatal and mesophyll conductances. (15 citations)
  • Mitochondrial AOX Supports Redox Balance of Photosynthetic Electron Transport, Primary Metabolite Balance, and Growth in Arabidopsis thaliana under High Light (7 citations)
  • Oxalate contents in leaves of two rice cultivars grown at a free-air CO2 enrichment (FACE) site (6 citations)

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

  • Enzyme
  • Botany
  • Gene

Ko Noguchi mainly investigates Biophysics, Mitochondrial respiratory chain, Electron transport chain, Photosystem II and Plant physiology. His research integrates issues of Wild type, Mutant, Photosystem I, Co2 concentration and Intracellular in his study of Biophysics. His Mitochondrial respiratory chain study integrates concerns from other disciplines, such as Plant ecology, Aerenchyma formation and Anoxic waters.

His Photosystem II research also covers Photosynthesis and Biochemistry studies. Plant physiology is a subfield of Botany that Ko Noguchi investigates. His work focuses on many connections between Tricarboxylic acid and other disciplines, such as Primary metabolite, that overlap with his field of interest in Carbon dioxide, Animal science, Chloroplast, Chloroplast stroma and Enzyme assay.
