| Outline of Final Research Achievements |
Through RNA seq analysis of isolated antheridia, a comprehensive list of genes specifically expressed during antheridial development was obtained, which enables us to draw a framework for gene expression program of the process. The list contains genes expressed in spermatogenous tissue at specific stage of development, which will serve as useful markers. A gene likely to be involved in early stages of sexual organ development was also identified through analysis of knock-out plants of selected transcription factor genes. These will be useful resources for us to contribute to our understanding sexual organ development. Other outputs from this project of a notable value include establishment of lines which mark apical notch region of thallus and catalogues of genes expressed in archegonia before and after fertilization.
In association to this project, I am serving as one of editors for the specially focused issue on Marchantia polymorpha as a model plant in Plant & Cell Physiology.
