| Outline of Final Research Achievements |
Our goal in this project is to uncover the mechanisms by which plant development is regulated through identification of novel peptide hormones and their specific receptors. In plants, small post-translationally modified peptides constitute the largest group of peptide hormones. We explored this type of peptide hormone by in silico gene screening coupled with biochemical and functional analysis, which led to the identification of two types of novel peptide hormones such as CEP family peptides regulating long-distance nitrogen demand signaling and CIF family peptides required for contiguous Casparian strip formation in roots. We also identified receptors for RGF family peptides involved in root meristem development.
