Utilizing the highly-diverse characteristic traits as foods, nutrients, functional ingredients, and amenities, horticultural crops including vegetables, fruits, and ornamentals are essential plant resources to support our healthy and high quality lives. Our research and education focus on elucidation, evaluation, and efficient application of physiological and ecological characteristics of vegetable and ornamental plant responses to various environmental factors in order to improve, develop, and create useful horticultural crop production systems through biotechnology and molecular biology.
