Research Overview

Utilization of DNA markers for dissection of plant genetic diversity, enhancement of plant improvement, and development of educational materials for biological sciences.

Research Subjects

  • 1. Genetic studies on sea buckthorn (Hippophae rhamnoides L.) using DNA markers.
  • 2. Development of experimental programs to understand plant genetic diversity.
  • 3. Development of stable detection methods of transgenes in commercial processed foods including genetically modified crops.

Introduction:

Various techniques for DNA analyses have been developed from the end of the 20th century.  Technological innovation has still continued.  Many kinds of DNA markers have been utilized for studies of plant evolution and breeding.  We are interested in a dioecious plant, sea buckthorn (Hippophae rhamnoides L.) shown in Fig. 1 as a highly hopeful horticultural crop to human beings, because it includes a wide variety of nutrients.  Our studies using DNA markers have started to shed the light on the genetics of sea buckthorn.
