| Research Abstract |
Plant cell walls contribute to the development and the functional specialization of cell types. It highly organized composite of many different polysaccharides, lignins and cell wall proteins. GRPs are thought to form a plate-like structure at the plasma membrane-cell wall interface. Then, we focused on highly expressed gene, OsGRP2, and analyzed the expression patterns and the mutant phenotypes. In the reproductive stage, although wild-type rice plants produced normal flower and seed, in osgrp2 mutants, anther dehiscence did not occur in about 50% flowers and about 78% seeds stopped their development in early stage. These results suggest that OsGRP2 might be important for the development of seed and anther.
