Overview

What is she best known for?

The fields of study she is best known for:

  • Gene
  • Enzyme
  • Photosynthesis

Ayumi Tanaka mainly investigates Biochemistry, Chlorophyll, Chlorophyll b, Chlorophyll cycle and Photosynthesis. Mutant, Reductase, Photosystem, Arabidopsis thaliana and Gene are among the areas of Biochemistry where the researcher is concentrating her efforts. Her Chlorophyll research is within the category of Botany.

Her Chlorophyll b research includes elements of Chloroplast, Chlorophyll fluorescence and Photosystem II. She interconnects Prochlorophytes and Accessory pigment in the investigation of issues within Chlorophyll cycle. Her Chlorophyll a research incorporates elements of Light-harvesting complexes of green plants and Chlorophyll c.

Her most cited work include:

  • Tetrapyrrole Biosynthesis in Higher Plants (510 citations)
  • Chlorophyll a oxygenase (CAO) is involved in chlorophyll b formation from chlorophyll a (330 citations)
  • Rice NON-YELLOW COLORING1 Is Involved in Light-Harvesting Complex II and Grana Degradation during Leaf Senescence (324 citations)

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

Ayumi Tanaka mostly deals with Biochemistry, Chlorophyll, Chlorophyll b, Botany and Chlorophyll a. Her Biochemistry and Mutant, Chloroplast, Reductase, Biosynthesis and Gene investigations all form part of her Biochemistry research activities. Her biological study spans a wide range of topics, including Photosynthesis, Photosystem, Photosystem II, Arabidopsis thaliana and Oxygenase.

Her work deals with themes such as Chlorophyll cycle, Prochlorophytes, Cyanobacteria, Chlamydomonas and Chlorophyll fluorescence, which intersect with Chlorophyll b. Her Botany research is multidisciplinary, relying on both Greening and Pigment. Her studies examine the connections between Chlorophyll a and genetics, as well as such issues in Light-harvesting complexes of green plants, with regards to Chlorosome.

She most often published in these fields:

  • Biochemistry (53.01%)
  • Chlorophyll (50.60%)
  • Chlorophyll b (31.93%)

What were the highlights of her more recent work (between 2016-2021)?

  • Chlorophyll (50.60%)
  • Biochemistry (53.01%)
  • Photosystem (21.08%)

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

The scientist’s investigation covers issues in Chlorophyll, Biochemistry, Photosystem, Mutant and Arabidopsis. Her Chlorophyll research integrates issues from Photosynthesis and Chloroplast. Her work is connected to Chlorophyll b, Chlorophyll a, Cofactor, Active site and Tetrahydromethanopterin, as a part of Biochemistry.

The concepts of her Chlorophyll b study are interwoven with issues in Chlorophyll cycle, Green algae and Metabolic pathway. Her Mutant study combines topics from a wide range of disciplines, such as Phenotype, Protein subunit and Pheophytin, Photosystem II. Her research integrates issues of Arabidopsis thaliana, Biophysics and Cell biology in her study of Arabidopsis.

Between 2016 and 2021, her most popular works were:

  • The SUFBC2D Complex is Required for the Biogenesis of All Major Classes of Plastid Fe‐S Proteins (28 citations)
  • The iron–sulfur cluster biosynthesis protein SUFB is required for chlorophyll synthesis, but not phytochrome signaling (19 citations)
  • Mg-dechelation of chlorophyll a by Stay-Green activates chlorophyll b degradation through expressing Non-Yellow Coloring 1 in Arabidopsis thaliana. (16 citations)

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

  • Enzyme
  • Gene
  • Bacteria

Her primary areas of investigation include Biochemistry, Mutant, Photosystem II, Photosystem and Chlorophyll. Her work on Chlorophyll b as part of general Biochemistry study is frequently connected to Cyclase activity, therefore bridging the gap between diverse disciplines of science and establishing a new relationship between them. Ayumi Tanaka usually deals with Chlorophyll b and limits it to topics linked to Metabolic pathway and Wild type, Arabidopsis thaliana, Chlorophyll cycle, Oxygenase and Green algae.

Ayumi Tanaka has researched Mutant in several fields, including Phenotype, RNA interference, Protein subunit and Protoporphyrin IX. Her Photosystem research is multidisciplinary, incorporating elements of Pheophytin, Chlamydomonas and Chlamydomonas reinhardtii. The study incorporates disciplines such as Photosynthesis, Cotyledon and Nicotiana tabacum in addition to Chlorophyll.
