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)

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)
