Overview

What is he best known for?

The fields of study he is best known for:

  • Botany
  • Ecology
  • Agriculture

Abscisic acid, Botany, Xylem, Agronomy and Shoot are his primary areas of study. The study incorporates disciplines such as Plant hormone, Soil water, Turgor pressure, Stomatal conductance and Water content in addition to Abscisic acid. William J. Davies has included themes like Biophysics and Rhizosphere in his Botany study.

His Xylem research includes themes of Helianthus annuus, Lycopersicon, Savia and Apoplast. His study in Shoot is interdisciplinary in nature, drawing from both Phloem, Transpiration stream, Cytokinin and Crop. His Poaceae research focuses on Soil drying and how it connects with Soil compaction.

His most cited work include:

  • Root Signals and the Regulation of Growth and Development of Plants in Drying Soil (945 citations)
  • ABA‐based chemical signalling: the co‐ordination of responses to stress in plants (749 citations)
  • Drought, ozone, ABA and ethylene: new insights from cell to plant to community. (486 citations)

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

His primary areas of investigation include Botany, Abscisic acid, Agronomy, Xylem and Shoot. His work focuses on many connections between Botany and other disciplines, such as Horticulture, that overlap with his field of interest in Woody plant. His biological study spans a wide range of topics, including Plant hormone, Helianthus annuus, Poaceae, Cytokinin and Epidermis.

William J. Davies regularly ties together related areas like Soil water in his Agronomy studies. The concepts of his Xylem study are interwoven with issues in Apoplast, Savia and Stomatal conductance. His Shoot study combines topics from a wide range of disciplines, such as Transpiration stream and Soil drying.

He most often published in these fields:

  • Botany (35.28%)
  • Abscisic acid (29.45%)
  • Agronomy (23.93%)

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

  • Perception (10.74%)
  • Agronomy (23.93%)
  • Soundscape (8.59%)

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

William J. Davies focuses on Perception, Agronomy, Soundscape, Agriculture and Speech recognition. His Agronomy study integrates concerns from other disciplines, such as Pollution and Transpiration. He focuses mostly in the field of Transpiration, narrowing it down to topics relating to Water content and, in certain cases, Abscisic acid.

His Soil phosphorus research is multidisciplinary, incorporating elements of Rhizosphere and Shoot. His study explores the link between Shoot and topics such as Signalling pathways that cross with problems in Horticulture. His DNS root zone course of study focuses on Arid and Botany.

Between 2015 and 2021, his most popular works were:

  • Ozone pollution will compromise efforts to increase global wheat production. (76 citations)
  • Increased soil phosphorus availability induced by faba bean root exudation stimulates root growth and phosphorus uptake in neighbouring maize (64 citations)
  • Phenotypic and genome-wide association analysis of spike ethylene in diverse wheat genotypes under heat stress. (48 citations)

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

  • Botany
  • Ecology
  • Agriculture

William J. Davies mainly investigates Agronomy, Food security, Irrigation, Botany and Agriculture. His work carried out in the field of Agronomy brings together such families of science as Rhizosphere, Nutrient and Xylem. In his work, Shoot is strongly intertwined with Root system, which is a subfield of Rhizosphere.

In his research, Abscisic acid is intimately related to Hormone, which falls under the overarching field of Shoot. His study focuses on the intersection of Xylem and fields such as Soil water with connections in the field of Transpiration. William J. Davies combines subjects such as SNP, Genetics, Genotyping and Horticulture with his study of Botany.
