  • 2014 - Fellow of the American Association for the Advancement of Science (AAAS)

Overview

What is she best known for?

The fields of study she is best known for:

  • Gene
  • Bacteria
  • Botany

Her primary areas of investigation include Rhizobium, Botany, Symbiosis, Rhizobia and Microbiology. Ann M. Hirsch has researched Rhizobium in several fields, including Mutant, Rhizobiaceae, Root hair and Nod factor. Her study in the field of Legume is also linked to topics like Nodule.

Her Symbiosis course of study focuses on Function and Rhizosphere, Ecosystem, Ecology, Ecology and Quorum sensing. Her studies in Rhizobia integrate themes in fields like Host specificity, Lectin and Plant nodule. Her Microbiology study combines topics in areas such as Phylogenetics, 16S ribosomal RNA, Burkholderia and Phylogenetic tree.

Her most cited work include:

  • Developmental biology of legume nodulation (508 citations)
  • Early nodulin genes are induced in alfalfa root outgrowths elicited by auxin transport inhibitors (322 citations)
  • Symbiotic mutants of rhizobium meliloti that uncouple plant from bacterial differentiation (264 citations)

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

Ann M. Hirsch mainly investigates Botany, Rhizobium, Symbiosis, Microbiology and Rhizobia. Her work carried out in the field of Botany brings together such families of science as Nitrogen fixation, Root nodule and Auxin, Gene. Her Rhizobium research is multidisciplinary, incorporating perspectives in Nod factor, Rhizobiaceae, Mutant and Root hair.

Her biological study spans a wide range of topics, including Lectin and Function. Her Microbiology research integrates issues from Nod, Bacteria, Biofilm, Sinorhizobium meliloti and Rhizobium leguminosarum. While the research belongs to areas of Rhizobia, Ann M. Hirsch spends her time largely on the problem of Rhizosphere, intersecting her research to questions surrounding Actinobacteria.

She most often published in these fields:

  • Botany (44.07%)
  • Rhizobium (24.86%)
  • Symbiosis (22.03%)

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

  • Bacteria (15.82%)
  • Botany (44.07%)
  • Microbiology (20.90%)

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

Her primary scientific interests are in Bacteria, Botany, Microbiology, Agriculture and Nitrogen fixation. She does research in Bacteria, focusing on Rhizobia specifically. Her Rhizobia study integrates concerns from other disciplines, such as Microbiome, Legume and Host.

She interconnects Rhizosphere and Actinobacteria in the investigation of issues within Botany. Her Microbiology research focuses on Symbiosis and how it connects with Lupinus angustifolius. Her research integrates issues of RNA, Solanum, Inoculation and Genome in her study of Nitrogen fixation.

Between 2016 and 2021, her most popular works were:

  • The Nodule Microbiome: N2-Fixing Rhizobia Do Not Live Alone (94 citations)
  • Whole Genome Analyses Suggests that Burkholderia sensu lato Contains Two Additional Novel Genera (Mycetohabitans gen. nov., and Trinickia gen. nov.): Implications for the Evolution of Diazotrophy and Nodulation in the Burkholderiaceae. (88 citations)
  • Antifungal Activity of Bacillus Species Against Fusarium and Analysis of the Potential Mechanisms Used in Biocontrol. (48 citations)

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

  • Gene
  • Bacteria
  • Botany

The scientist’s investigation covers issues in Bacteria, Microbiology, Biotechnology, Antimicrobial and Rhizobia. Her Microbiology study incorporates themes from Lupinus, Biopesticide, Fungicide and Chitinase. The various areas that Ann M. Hirsch examines in her Biotechnology study include Bacillus, Pesticide, Biological pest control, Agrochemical and Food security.

The study incorporates disciplines such as Burkholderia cepacia complex, Burkholderia cenocepacia and Siderophore in addition to Antimicrobial. Her Rhizobia research includes elements of Microbiome and Botany. Her biological study spans a wide range of topics, including Symbiosis, Host and Medicago.
