His main research concerns Botany, Gibberellin, Biochemistry, Stereochemistry and Shoot. His studies deal with areas such as Oryza sativa and Rice plant as well as Botany. The study incorporates disciplines such as Kovats retention index, Biosynthesis, Gibberellin biosynthesis, Bioassay and Endogeny in addition to Gibberellin.

His Biochemistry study combines topics from a wide range of disciplines, such as Archegonium and Lygodium. His research in Stereochemistry intersects with topics in Spore germination, Ophiobolins, Fungi imperfecti and Fern. His biological study spans a wide range of topics, including Gibberellic acid and Plant physiology.

His most cited work include:

  • Qualitative and Quantitative Analyses of Gibberellins in Vegetative Shoots of Normal, dwarf-1, dwarf-2, dwarf-3, and dwarf-5 Seedlings of Zea mays L. (168 citations)
  • Studies of sites of action of a new plant growth retardant (E)-1-(4-chlorophenyl)-4,4-dimethyl-2-(1,2,4-triazol-1-yl)-1-penten-3-ol (S-3307) and comparative effects of its stereoisomers in a cell-free system from Cucurbita maxima (158 citations)
  • The dominant non-gibberellin-responding dwarf mutant (D8) of maize accumulates native gibberellins. (122 citations)

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

His primary areas of study are Botany, Gibberellin, Stereochemistry, Biochemistry and Isolation. The various areas that Nobutaka Takahashi examines in his Botany study include Endogeny and Oryza sativa. His Oryza sativa study frequently draws connections between related disciplines such as Poaceae.

The concepts of his Gibberellin study are interwoven with issues in Pharbitis nil, Germination and Fungus. His Stereochemistry research focuses on Piericidin A and how it connects with Chemical structure. As part of his studies on Biochemistry, Nobutaka Takahashi frequently links adjacent subjects like Mating.

He most often published in these fields:

  • Botany (43.93%)
  • Gibberellin (35.19%)
  • Stereochemistry (22.82%)

What were the highlights of his more recent work (between 1989-2014)?

  • Botany (43.93%)
  • Gibberellin (35.19%)
  • Biochemistry (21.12%)

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

The scientist’s investigation covers issues in Botany, Gibberellin, Biochemistry, Stereochemistry and Chromatography. Nobutaka Takahashi regularly ties together related areas like Gas chromatography in his Botany studies. His research integrates issues of Gibberellic acid, Endogeny and Oryza sativa in his study of Gibberellin.

His Endogeny research includes themes of Lactuca and Kovats retention index. His Stereochemistry study incorporates themes from Nitro, Molecule, Biological activity, Enzyme inhibitor and Photosystem II. His work in Chromatography tackles topics such as Amino acid which are related to areas like Mass spectrum and Metabolite.

Between 1989 and 2014, his most popular works were:

  • Light effects on endogenous levels of gibberellins in photoblastic lettuce seeds (82 citations)
  • Gibberellin A3 Is Biosynthesized from Gibberellin A20 via Gibberellin A5 in Shoots of Zea mays L. (73 citations)
  • Effects of Low Irradiance Stress on Gibberellin Levels in Pea Seedlings (62 citations)

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

  • Botany
  • Enzyme
  • Organic chemistry

Nobutaka Takahashi mainly investigates Botany, Gibberellin, Biochemistry, Brassinolide and Biosynthesis. The Botany study combines topics in areas such as Radioimmunoassay and Cytokinin. He interconnects Gibberellic acid and Endogeny in the investigation of issues within Gibberellin.

His Biochemistry research includes elements of Chromatography, Shoot and Cucurbita maxima. His studies in Brassinolide integrate themes in fields like Catharanthus roseus, Gall, Crown and Metabolism. In his study, which falls under the umbrella issue of Stamen, Stereochemistry is strongly linked to Steroid.
