Overview

What is he best known for?

The fields of study he is best known for:

  • Botany
  • Enzyme
  • Gene

His primary scientific interests are in Strigolactone, Botany, Orobanche, Mutant and Germination. His Strigolactone study frequently draws connections to other fields, such as Karrikin. The various areas that Koichi Yoneyama examines in his Botany study include Phosphorus deficiency, Rhizosphere and Parasitic plant.

His Orobanche research is multidisciplinary, incorporating elements of Mycorrhiza, Striga, Orobanchaceae and Nicotiana tabacum. His study focuses on the intersection of Mutant and fields such as Oryza sativa with connections in the field of Stereoisomerism. His Germination research focuses on Cultivar and how it connects with Poaceae, Pennisetum typhoideum, Sorghum and Plant roots.

His most cited work include:

  • Inhibition of shoot branching by new terpenoid plant hormones (1342 citations)
  • The Strigolactone Story (477 citations)
  • Nitrogen deficiency as well as phosphorus deficiency in sorghum promotes the production and exudation of 5-deoxystrigol, the host recognition signal for arbuscular mycorrhizal fungi and root parasites (276 citations)

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

The scientist’s investigation covers issues in Botany, Germination, Strigolactone, Orobanche and Biochemistry. His research is interdisciplinary, bridging the disciplines of Parasitic plant and Botany. His biological study spans a wide range of topics, including Red Clover and Plant physiology.

His Strigolactone study which covers Phosphorus deficiency that intersects with Nitrogen deficiency. His Orobanche research incorporates themes from Host and Mycorrhiza. His Shoot research integrates issues from Auxin and Weed.

He most often published in these fields:

  • Botany (57.35%)
  • Germination (34.60%)
  • Strigolactone (27.01%)

What were the highlights of his more recent work (between 2012-2020)?

  • Botany (57.35%)
  • Strigolactone (27.01%)
  • Germination (34.60%)

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

His main research concerns Botany, Strigolactone, Germination, Biosynthesis and Biochemistry. His work in Orobanche minor, Striga hermonthica, Shoot, Orobanche and Orobanchaceae are all subfields of Botany research. He has researched Orobanche in several fields, including Sorgolactone and Radicle.

His research in Strigolactone intersects with topics in Plant hormone, Carotenoid, Oryza sativa, Nutrient and Human fertilization. The concepts of his Germination study are interwoven with issues in Monochoria vaginalis and Host, Parasitic plant. Koichi Yoneyama works mostly in the field of Biosynthesis, limiting it down to concerns involving Mutant and, occasionally, Cell biology and Auxin.

Between 2012 and 2020, his most popular works were:

  • Carlactone is converted to carlactonoic acid by MAX1 in Arabidopsis and its methyl ester can directly interact with AtD14 in vitro (213 citations)
  • Carlactone is converted to carlactonoic acid by MAX1 in Arabidopsis and its methyl ester can directly interact with AtD14 in vitro (213 citations)
  • Strigolactones are involved in phosphate- and nitrate-deficiency-induced root development and auxin transport in rice (146 citations)

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

  • Botany
  • Enzyme
  • Gene

His primary areas of study are Strigolactone, Botany, Biochemistry, Arabidopsis and Mutant. The study incorporates disciplines such as Sorgolactone, Sorghum, Agronomy and Phosphorus in addition to Strigolactone. His studies deal with areas such as Oryza sativa and Auxin as well as Botany.

The Arabidopsis study combines topics in areas such as Rhizosphere and Shoot. His Shoot research is multidisciplinary, incorporating elements of Nutrient, Phosphorus deficiency, Nitrogen deficiency and Human fertilization. The concepts of his Germination study are interwoven with issues in Host and Parasitic plant.
