Overview

What is she best known for?

The fields of study she is best known for:

  • Botany
  • Enzyme
  • Gene

Her scientific interests lie mostly in Botany, Tetranychus urticae, Herbivore, Green leaf volatiles and Jasmonic acid. The Botany study combines topics in areas such as Arabidopsis thaliana, Jasmonate and Biochemistry. Her research investigates the connection with Tetranychus urticae and areas like Acariformes which intersect with concerns in Biological pest control.

Her biological study spans a wide range of topics, including Brassica, Plant defense against herbivory and Cotesia glomerata. Rika Ozawa combines subjects such as Arabidopsis, Transformation and Odor with her study of Green leaf volatiles. Her Jasmonic acid study combines topics from a wide range of disciplines, such as Methyl salicylate and Regulation of gene expression.

Her most cited work include:

  • Herbivory-induced volatiles elicit defence genes in lima bean leaves. (572 citations)
  • Involvement of Jasmonate- and Salicylate-Related Signaling Pathways for the Production of Specific Herbivore-Induced Volatiles in Plants (233 citations)
  • Changing green leaf volatile biosynthesis in plants: An approach for improving plant resistance against both herbivores and pathogens (218 citations)

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

Rika Ozawa focuses on Botany, Herbivore, Tetranychus urticae, Jasmonic acid and Biochemistry. Her Botany research is multidisciplinary, relying on both Spider and Arabidopsis. The Arabidopsis study combines topics in areas such as Botrytis cinerea and Arabidopsis thaliana.

Rika Ozawa studied Herbivore and Plant defense against herbivory that intersect with Elicitor. Her Tetranychus urticae research is multidisciplinary, relying on both Phytoseiidae, Acariformes, Predation and Olfactometer. The concepts of her Jasmonic acid study are interwoven with issues in Methyl salicylate, Methyl jasmonate, Biological pest control and Microbiology.

She most often published in these fields:

  • Botany (65.17%)
  • Herbivore (22.47%)
  • Tetranychus urticae (17.98%)

What were the highlights of her more recent work (between 2016-2020)?

  • Botany (65.17%)
  • Horticulture (12.36%)
  • Plant defense against herbivory (7.87%)

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

The scientist’s investigation covers issues in Botany, Horticulture, Plant defense against herbivory, Larva and Host. Rika Ozawa merges Botany with Angelica acutiloba in her research. Her research on Horticulture also deals with topics like

  • Integrated pest management which intersects with area such as Crop, Predator, Mite, Limonene and Spider,
  • Spodoptera litura that intertwine with fields like Biological pest control, Animal ecology and Infestation.

Her Plant defense against herbivory research incorporates themes from Insect, Resistance and White. Her Solidago altissima course of study focuses on Isoflavones and Herbivore. Her Cotesia vestalis research incorporates elements of Arabidopsis thaliana, Arabidopsis, Mutant, Reductase and Plant physiology.

Between 2016 and 2020, her most popular works were:

  • Tetranins: new putative spider mite elicitors of host plant defense (13 citations)
  • Identification of a Hexenal Reductase That Modulates the Composition of Green Leaf Volatiles. (12 citations)
  • Experience of plant infestation by the omnivorous arthropod Nesidiocoris tenuis affects its subsequent responses to prey-infested plant volatiles (12 citations)

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

  • Botany
  • Enzyme
  • Gene

Botany, Green leaf volatiles, Plant defense against herbivory, Tachinidae and Behavioral response are her primary areas of study. Her Olfactometer research extends to Botany, which is thematically connected. She interconnects Predation, Biological pest control, Horticulture, Animal ecology and Cutworm in the investigation of issues within Olfactometer.

Her Tachinidae research includes themes of Terpenoid and Enzyme. Her work in Tetranychus urticae tackles topics such as Spider mite which are related to areas like Jasmonate. The study incorporates disciplines such as Arabidopsis thaliana, Arabidopsis, Mutant, Reductase and Plant physiology in addition to Cotesia vestalis.
