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

Her main research concerns Botany, Medicago truncatula, Symbiosis, Gene and Biochemistry. Her Botany research is multidisciplinary, incorporating perspectives in Arbuscular mycorrhiza, Gene expression, Mycorrhiza and Phosphate. Maria J. Harrison is studying Periarbuscular membrane, which is a component of Medicago truncatula.

Her research integrates issues of Ecology, Nutrient, Endosymbiosis, Mutant and Hypha in her study of Symbiosis. Gene is a subfield of Genetics that Maria J. Harrison tackles. In general Biochemistry, her work in Chalcone synthase, Apoplast and Chalcone isomerase is often linked to Phytoalexin linking many areas of study.

She most often published in these fields:

Botany (55.40%)
Medicago truncatula (42.45%)
Symbiosis (36.69%)

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

Symbiosis (36.69%)
Botany (55.40%)
Cell biology (19.42%)

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

Maria J. Harrison mainly focuses on Symbiosis, Botany, Cell biology, Arbuscular mycorrhiza and Gene. Her Symbiosis study integrates concerns from other disciplines, such as Photosynthesis, Sorghum and 16S ribosomal RNA, Gammaproteobacteria. Her Botany research includes themes of Crop, Rhizophagus irregularis, Signal transduction, Alphaproteobacteria and Arbuscular mycorrhizal fungi.

Her studies deal with areas such as Gene expression, Endosymbiosis, Mutant, Periarbuscular membrane and Hypha as well as Cell biology. Within one scientific family, she focuses on topics pertaining to Medicago truncatula under Arbuscular mycorrhiza, and may sometimes address concerns connected to Biochemistry. Her studies in Gene integrate themes in fields like Kinase and Fungal colonization.

Between 2016 and 2021, her most popular works were:

Arbuscular mycorrhiza-specific enzymes FatM and RAM2 fine-tune lipid biosynthesis to promote development of arbuscular mycorrhiza. (125 citations)
Plant Signaling and Metabolic Pathways Enabling Arbuscular Mycorrhizal Symbiosis. (105 citations)
A comprehensive draft genome sequence for lupin (Lupinus angustifolius), an emerging health food: insights into plant–microbe interactions and legume evolution (99 citations)

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

Gene
DNA
Enzyme

Her scientific interests lie mostly in Endosymbiosis, Botany, Gene, Genome and Medicago truncatula. Maria J. Harrison usually deals with Endosymbiosis and limits it to topics linked to Cell biology and Mutant, Transcription factor, Gene expression and Metabolic pathway. Her Gene study contributes to a more complete understanding of Genetics.

Maria J. Harrison works on Medicago truncatula which deals in particular with Periarbuscular membrane. Her biological study spans a wide range of topics, including RNA interference, Endoplasmic reticulum and Transcription. Her Agronomy research incorporates themes from Plant disease resistance and Symbiosis.
