Description

Rice is one of the most important crops in the world, and thus as a model plant it has been the subject of much research. But many kinds of rice species are not easy to handle in a laboratory space. To investigate the dwarf rice’s suitability for experimental work, we analyzed the characteristics of Hosetsu-dwarf. Hosetsu-dwarf has small body size, a short life cycle, and normal seed formation. We established a standard method for its hydroponic cultivation. We found as well that its endosperm polypeptide compositions and the morphological observation were not unusual. Thus we propose that Hosetsu-dwarf is an excellent tool for basic studies of seed development.
