Overview

What is he best known for?

The fields of study he is best known for:

Botany
Enzyme
Gene

His primary areas of investigation include Botany, Agrobacterium, Hairy root culture, Transformation and Solanaceae. The concepts of his Botany study are interwoven with issues in Hyoscyamine, Tropane alkaloid and Horticulture. His Agrobacterium research is multidisciplinary, incorporating perspectives in Dry weight, Murashige and Skoog medium, Shoot and Biosynthesis.

His Hairy root culture research includes elements of Derivative, Xanthone and Swertia japonica. His Transformation research incorporates elements of Naphthoquinone and Lithospermum erythrorhizon. His work investigates the relationship between Solanaceae and topics such as Atropa belladonna that intersect with problems in clone, Hydroponics and Axenic.

His most cited work include:

Alkaloid production by hairy root cultures in Atropa belladonna (206 citations)
