Abstract: Rice(Oryza sativa L.), which has a small genome in cereal plants, has several advantages as a model species for studying molecular biology and developmental biology. Although molecular studies on rice development have just begun, a growing number of investigation materials of molecular development in rice are now being increased. In the review, first, molecular developmental mechanisms of flower and floral organs are summarized. Then, molecular mechanisms of embryogenesis are discussed. At last, recent progress toward molecular process of formation and development of vegetative organ are described.

Key words: Oryza sativa, development, flower, embryogenesis, stem organ, gene
