| Research Abstract |
We revealed the gene expression profiles throughout whole reproductive stages/tissues of rice, and found many genes which were expressed in the tissues as a developmental stage-dependent manner. The genes which showed tissue-/stage-specific expression were supposed to have specialized function in plant reproduction steps, such as development of gametophytes (pollen grains and egg cells), pollination, fertilization, and early developmental stages of embryos. We also established methods of the genome-wide gene expression analysis for small amount of tissues. Based on the established methods, the gene expression profiles in developing microspores and egg cells were revealed.
