Overview

What is she best known for?

The fields of study she is best known for:

  • Gene
  • Enzyme
  • Botany

The scientist’s investigation covers issues in Biochemistry, Botany, Oryza sativa, Nicotianamine synthase and Gene. Her Biochemistry study integrates concerns from other disciplines, such as Vascular bundle and Phloem. She interconnects Genetically modified crops, Phytoremediation and Mutant in the investigation of issues within Botany.

Her study focuses on the intersection of Oryza sativa and fields such as Ion transporter with connections in the field of Stele. Naoko K. Nishizawa has included themes like Rhizosphere, Biosynthesis and Hordeum vulgare in her Nicotianamine synthase study. In her study, which falls under the umbrella issue of Gene, Microarray analysis techniques, Arabidopsis, Cytokinesis, Cell growth and Cell is strongly linked to Cell biology.

Her most cited work include:

  • Iron Uptake, Translocation, and Regulation in Higher Plants (667 citations)
  • Role of Nicotianamine in the Intracellular Delivery of Metals and Plant Reproductive Development (504 citations)
  • Rice plants take up iron as an Fe3+-phytosiderophore and as Fe2+. (479 citations)

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

Her scientific interests lie mostly in Biochemistry, Botany, Gene, Nicotianamine and Oryza sativa. Nicotiana tabacum is closely connected to Hordeum vulgare in her research, which is encompassed under the umbrella topic of Biochemistry. Her Botany research incorporates themes from Genetically modified crops and Chromosomal translocation.

Her work is dedicated to discovering how Gene, Cell biology are connected with Arabidopsis and Gene knockdown and other disciplines. She works mostly in the field of Nicotianamine, limiting it down to topics relating to Endosperm and, in certain cases, Starch. Her Oryza sativa study incorporates themes from Biofortification and Genetically modified rice.

She most often published in these fields:

  • Biochemistry (61.43%)
  • Botany (52.00%)
  • Gene (38.29%)

What were the highlights of her more recent work (between 2012-2021)?

  • Biochemistry (61.43%)
  • Botany (52.00%)
  • Iron deficiency (25.71%)

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

Biochemistry, Botany, Iron deficiency, Gene and Nicotianamine are her primary areas of study. Her Botany research incorporates elements of Rhizosphere, ATP synthase, Horticulture and Chromosomal translocation. Her Iron deficiency research incorporates themes from Calcareous and Reductase.

Her study on Gene is mostly dedicated to connecting different topics, such as Cell biology. The Nicotianamine study combines topics in areas such as Transformation, Vesicular transport protein, Biofortification and Shoot. As part of one scientific family, Naoko K. Nishizawa deals mainly with the area of Oryza sativa, narrowing it down to issues related to the Exodermis, and often Cell wall.

Between 2012 and 2021, her most popular works were:

  • Using membrane transporters to improve crops for sustainable food production (316 citations)
  • Iron-binding haemerythrin RING ubiquitin ligases regulate plant iron responses and accumulation (129 citations)
  • Iron-binding haemerythrin RING ubiquitin ligases regulate plant iron responses and accumulation (129 citations)

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

  • Gene
  • Enzyme
  • Botany

Naoko K. Nishizawa mainly investigates Biochemistry, Botany, Oryza sativa, Nicotianamine and Biofortification. Her Biochemistry study frequently draws parallels with other fields, such as Aerenchyma. Her Botany study incorporates themes from Transcriptome and Cell biology.

The study incorporates disciplines such as Biotechnology, Mutant, Agronomy and Phytase in addition to Oryza sativa. Her Biofortification study combines topics in areas such as Food science, Ferritin, Nicotianamine synthase and Plant breeding. Naoko K. Nishizawa works mostly in the field of Iron deficiency, limiting it down to topics relating to Gene and, in certain cases, Metabolism and Hemerythrin, as a part of the same area of interest.
