Overview

What is he best known for?

The fields of study he is best known for:

  • Botany
  • Enzyme
  • Gene

The scientist’s investigation covers issues in Phytochrome, Botany, Shade avoidance, Mutant and Wild type. His Phytochrome research is multidisciplinary, incorporating perspectives in Tree canopy, Competition, Photomorphogenesis, Adaptation and Phytochrome A. His study in Botany is interdisciplinary in nature, drawing from both Arabidopsis thaliana, Etiolation and Cell biology.

His research in Shade avoidance intersects with topics in Transgene, Ecology, Perception and Solanaceae. His Ecology research includes elements of Daylight and Photobiology. His studies deal with areas such as Evolutionary biology, Biological evolution, Phytochrome B and Plant Physiological Phenomena as well as Perception.

His most cited work include:

  • Phytochromes and light signal perception by plants—an emerging synthesis (1118 citations)
  • Light Quality, Photoperception, and Plant Strategy (1020 citations)
  • The shade avoidance syndrome: multiple responses mediated by multiple phytochromes (530 citations)

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

Phytochrome, Botany, Far-red, Shade avoidance and Etiolation are his primary areas of study. His Phytochrome research is multidisciplinary, relying on both Mutant, Hypocotyl, Photomorphogenesis, Cell biology and Phytochrome A. His Botany study combines topics from a wide range of disciplines, such as Arabidopsis thaliana, Biophysics, Arabidopsis and Horticulture.

His studies in Far-red integrate themes in fields like Enzyme assay, Phenylalanine ammonia-lyase activity, Optics, Plant physiology and Mode of action. As a part of the same scientific study, Harry Smith usually deals with the Shade avoidance, concentrating on Genetically modified crops and frequently concerns with Dwarfing. His research in Etiolation tackles topics such as Chlorophyll which are related to areas like Pisum and Chloroplast.

  • Phytochrome (65.29%)
  • Botany (52.07%)
  • Far-red (19.01%)

What were the highlights of his more recent work (between 1998-2013)?

  • Phytochrome (65.29%)
  • Botany (52.07%)
  • Molecular ecology (3.31%)

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

Harry Smith mostly deals with Phytochrome, Botany, Molecular ecology, Phytochrome A and Library science. His Phytochrome research integrates issues from Specific activity, Cotyledon, Shade avoidance, Cucurbita and Hypocotyl. The concepts of his Shade avoidance study are interwoven with issues in Far-red, Photomorphogenesis and Plant physiology.

His Plant cell research extends to the thematically linked field of Botany. His biological study spans a wide range of topics, including Biophysics, Etiolation and Seedling. His research investigates the connection with Evolutionary biology and areas like Biological evolution which intersect with concerns in Ecology.

Between 1998 and 2013, his most popular works were:

  • Phytochromes and light signal perception by plants—an emerging synthesis (1118 citations)
  • A road map for molecular ecology. (90 citations)
  • Physiological interactions of phytochromes A, B1 and B2 in the control of development in tomato. (75 citations)

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

  • Enzyme
  • Gene
  • Botany

His primary areas of study are Phytochrome, Ecology, Phytochrome A, Botany and Ecology. The various areas that Harry Smith examines in his Phytochrome study include Mutant and Shade avoidance. His work carried out in the field of Shade avoidance brings together such families of science as Biological evolution, Plant Physiological Phenomena, Perception and Photobiology.

His Phytochrome A research is multidisciplinary, incorporating elements of Biophysics, Phytochrome B, Carrier protein, Basic Helix-Loop-Helix Transcription Factors and Arabidopsis Proteins. He has researched Botany in several fields, including Far-red, Photomorphogenesis, Etiolation and Cell biology. His Ecology research includes elements of Evolutionary biology and MOLECULAR BIOLOGY METHODS.
