Overview

What is he best known for?

The fields of study he is best known for:

  • Botany
  • Ecology
  • Gene

His main research concerns Botany, Xylem, Cambium, Tracheid and Anatomy. His work on Kalopanax, Growing season and Japonica as part of general Botany study is frequently linked to Water transport and Cavitation, therefore connecting diverse disciplines of science. His Xylem research integrates issues from Fiber, Secondary ion mass spectrometry, Maple and Deciduous.

His Cambium research incorporates elements of Hardwood, Dormancy, Late winter and Abies sachalinensis. His studies deal with areas such as Ultrastructure, Biophysics, Microtubule and Cell wall as well as Tracheid. His research investigates the connection with Biophysics and areas like Parenchyma which intersect with concerns in Programmed cell death.

His most cited work include:

  • Regulation of cambial activity in relation to environmental conditions: understanding the role of temperature in wood formation of trees (151 citations)
  • Relationships between cambial activity, cell differentiation and the localization of starch in storage tissues around the cambium in locally heated stems of Abies sachalinensis (Schmidt) Masters (137 citations)
  • Xyloglucan Endo-transglycosylase (XET) Functions in Gelatinous Layers of Tension Wood Fibers in Poplar—A Glimpse into the Mechanism of the Balancing Act of Trees (136 citations)

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

Botany, Xylem, Cambium, Cell wall and Tracheid are his primary areas of study. His Botany study frequently involves adjacent topics like Horticulture. The Xylem study combines topics in areas such as Starch, Anatomy, Phloem, Dormancy and Parenchyma.

His Cambium research is multidisciplinary, incorporating elements of Hardwood and Evergreen. His research integrates issues of Cellulose, Biophysics and Lignin in his study of Cell wall. Ryo Funada interconnects Ultrastructure and Abies sachalinensis in the investigation of issues within Tracheid.

He most often published in these fields:

  • Cambium (25.63%)

What were the highlights of his more recent work (between 2013-2021)?

  • Xylem (46.73%)
  • Botany (65.33%)
  • Cambium (25.63%)

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

Ryo Funada spends much of his time researching Xylem, Botany, Cambium, Tracheid and Cell wall. His Xylem research is multidisciplinary, relying on both Temperate climate, Starch, Woody plant, Dormancy and Programmed cell death. His study in Plant physiology, Deciduous, Bud growth, Cryptomeria and Japonica is carried out as part of his studies in Botany.

His Cambium research includes themes of Chamaecyparis pisifera, Phloem, Evergreen and Auxin. His work investigates the relationship between Tracheid and topics such as Chamaecyparis that intersect with problems in Cell morphology and Hydraulic conductivity. Ryo Funada has included themes like Diospyros kaki, Biophysics, Callus, Lignin and Intracellular in his Cell wall study.

Between 2013 and 2021, his most popular works were:

  • EARLYWOOD VESSELS IN RING-POROUS TREES BECOME FUNCTIONAL FOR WATER TRANSPORT AFTER BUD BURST AND BEFORE THE MATURATION OF THE CURRENT-YEAR LEAVES (44 citations)
  • Increased lodging resistance in long-culm, low-lignin gh2 rice for improved feed and bioenergy production (41 citations)
  • The effects of localized heating and disbudding on cambial reactivation and formation of earlywood vessels in seedlings of the deciduous ring-porous hardwood, Quercus serrata (33 citations)

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

  • Botany
  • Ecology
  • Gene

Ryo Funada mainly focuses on Botany, Xylem, Dormancy, Tracheid and Deciduous. His work in the fields of Cambium overlaps with other areas such as Water transport. His research in Cambium intersects with topics in Chamaecyparis pisifera, Chamaecyparis, Cell morphology, Phloem and Evergreen.

His Dormancy study combines topics in areas such as Secondary cell wall, Cryptomeria, Cell division and Starch. His studies link Cellulose with Tracheid. His work in Deciduous covers topics such as Quercus serrata which are related to areas like Hardwood.
