Overview

What is he best known for?

The fields of study he is best known for:

Gene
Botany
Enzyme

Robert E. Sharp mainly investigates Botany, Elongation, Shoot, Abscisic acid and Root growth. His Botany study combines topics in areas such as Arabidopsis thaliana, Lateral root and Osmoregulation. His Elongation studies intersect with other subjects such as Horticulture, Cell wall, Water potential, Apex and Peroxidase.

His Abscisic acid study deals with Poaceae intersecting with Fluridone. His work carried out in the field of Root growth brings together such families of science as Water stress and Turgor pressure. Robert E. Sharp has researched Agronomy in several fields, including Vermiculite, Animal science and Soil horizon.

His most cited work include:

Root growth maintenance during water deficits: physiology to functional genomics (468 citations)
Growth of the Maize Primary Root at Low Water Potentials : III. Role of Increased Proline Deposition in Osmotic Adjustment. (441 citations)
Solute regulation and growth by roots and shoots of water-stressed maize plants. (395 citations)

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

His primary areas of study are Botany, Elongation, Abscisic acid, Agronomy and Cell wall. His Botany research incorporates elements of Arabidopsis thaliana, Horticulture, Water potential and Cell biology. Other disciplines of study, such as Poaceae, Biochemistry, Biophysics, Apex and Vermiculite, are mixed together with his Elongation studies.

The concepts of his Apex study are interwoven with issues in Expansin and Turgor pressure. His Fluridone study in the realm of Abscisic acid interacts with subjects such as Ethylene. His research integrates issues of Peroxidase and Proteomics in his study of Cell wall.

He most often published in these fields:

Botany (44.32%)
Elongation (40.91%)
Abscisic acid (29.55%)

What were the highlights of his more recent work (between 2015-2021)?

Agronomy (22.73%)
Nutrient (5.68%)
Cell biology (11.36%)

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

His primary scientific interests are in Agronomy, Nutrient, Cell biology, Root and Ecology. Western corn rootworm and Infestation are among the areas of Agronomy where the researcher is concentrating his efforts. He focuses mostly in the field of Infestation, narrowing it down to matters related to Greenhouse and, in some cases, Shoot.

As part of one scientific family, Robert E. Sharp deals mainly with the area of Cell biology, narrowing it down to issues related to the Seedling, and often Gene regulatory network, microRNA, Root growth and Water deficit. His Plant physiology study is related to the wider topic of Botany. The Botany study combines topics in areas such as Real-time polymerase chain reaction, Abscisic acid, Gene, Transcription factor and Gene expression profiling.

Between 2015 and 2021, his most popular works were:

Science-based intensive agriculture: Sustainability, food security, and the role of technology (14 citations)
Water deficit‐induced changes in transcription factor expression in maize seedlings (11 citations)
Plasma membrane proteomics in the maize primary root growth zone: novel insights into root growth adaptation to water stress. (11 citations)

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

Gene
Botany
Enzyme

His scientific interests lie mostly in Cell biology, Intensive farming, Natural resource economics, Business and Sustainability. He has included themes like Abscisic acid, Botany, Gene expression profiling, Transcription factor and Real-time polymerase chain reaction in his Cell biology study. He integrates Intensive farming with Food security in his research.
