  • 2023 - Research.com Plant Science and Agronomy in Brazil Leader Award
  • 2022 - Research.com Plant Science and Agronomy in Brazil Leader Award

Overview

What is she best known for?

The fields of study she is best known for:

  • Botany
  • Ecology
  • Agronomy

Johanna Döbereiner focuses on Nitrogen fixation, Botany, Agronomy, Diazotroph and Endophyte. Johanna Döbereiner works on Nitrogen fixation which deals in particular with Nitrogenase. Her Botany study combines topics in areas such as Sugar, Acetobacter and Acetic acid.

In her study, Urea, Plant tissue and Fertilizer is inextricably linked to Nitrogen balance, which falls within the broad field of Agronomy. Particularly relevant to Herbaspirillum is her body of work in Diazotroph. The concepts of her Poaceae study are interwoven with issues in Rhizosphere and Azospirillum brasilense.

Her most cited work include:

  • A new acid-tolerant nitrogen-fixing bacterium associated with sugarcane (526 citations)
  • Recent advances in BNF with non-legume plants (318 citations)
  • Biological nitrogen fixation associated with sugar cane and rice: Contributions and prospects for improvement (300 citations)

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

Nitrogen fixation, Botany, Agronomy, Horticulture and Diazotroph are her primary areas of study. Her primary area of study in Nitrogen fixation is in the field of Nitrogenase. Her work carried out in the field of Botany brings together such families of science as Inoculation, Microbial inoculant, Symbiosis and Azospirillum lipoferum.

Her Agronomy research is multidisciplinary, incorporating elements of Soil water and Plant physiology. Her Horticulture research includes themes of Macroptilium atropurpureum and Weed. Her work in the fields of Diazotroph, such as Herbaspirillum, intersects with other areas such as Elaeis guineensis.

She most often published in these fields:

  • Nitrogen fixation (48.00%)
  • Botany (48.00%)
  • Agronomy (33.60%)

What were the highlights of her more recent work (between 1994-2005)?

  • Botany (48.00%)
  • Diazotroph (21.60%)
  • Herbaspirillum (12.80%)

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

Johanna Döbereiner mostly deals with Botany, Diazotroph, Herbaspirillum, Nitrogen fixation and Herbaspirillum seropedicae. Her Botany course of study focuses on Burkholderia and Cultivar. Her research in Diazotroph intersects with topics in Microorganism, Acetobacter, Flagellum and Horticulture.

Her Herbaspirillum study integrates concerns from other disciplines, such as Endophyte, Vascular tissue, 16S ribosomal RNA, Ribosomal RNA and Rhizobacteria. Her studies in Nitrogen fixation integrate themes in fields like Agroforestry, Agronomy, Saccharum officinarum, Agriculture and Cane. Her research integrates issues of Proteobacteria, Herbaspirillum rubrisubalbicans, Crop and Microbiology in her study of Herbaspirillum seropedicae.

Between 1994 and 2005, her most popular works were:

  • Recent advances in BNF with non-legume plants (318 citations)
  • Biological nitrogen fixation associated with sugar cane and rice: Contributions and prospects for improvement (300 citations)
  • Occurrence of the endophytic diazotrophs Herbaspirillum spp. in roots, stems, and leaves, predominantly of Gramineae (215 citations)

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

  • Botany
  • Ecology
  • Agriculture

The scientist’s investigation covers issues in Diazotroph, Herbaspirillum, Botany, Nitrogen fixation and Herbaspirillum seropedicae. Her Herbaspirillum research incorporates themes from Endophyte, Rhizobacteria and Vascular tissue. Her biological study spans a wide range of topics, including Biofuel and Agronomy.

Her research in Agronomy intersects with topics in Agriculture, Tropics, Cane, Nitrogen balance and Rhizosphere. Her Herbaspirillum seropedicae research is multidisciplinary, incorporating elements of Herbaspirillum rubrisubalbicans and Azospirillum lipoferum. Her Herbaspirillum rubrisubalbicans research is multidisciplinary, relying on both Soil biology, Herbaceous plant, Xylem and Microbiology.
