| Outline of Final Research Achievements |
To elucidate the physiological mechanisms of seed germination and seedling growth in eelgrass, the physiological and molecular biological studies were performed. During seed dormancy and germination in eelgrass, the approximately 230 eelgrass genes were expressed, and the genes for respiration, salt tolerance, absorbing water, and perception of plant hormone were expressed markedly. The transgenic Arabidopsis which expressed eelgrass genes were analyzed, and it is indicated that at least three genes may be involved in salt tolerance and hypoxia tolerance. It is also suggested that eelgrass is likely to have the system of photoresponse and reception of blue and red light. In this study, the part of the physiological mechanisms involved in seed germination and growth became clear in eelgrass.
