| Current Research Topics | (1) Functional analysis of a barley protein P23k in (1,3;1,4)-β-D-glucan synthesis: P23k is a monocot-unique protein that is highly expressed in barley. Loss-of-function studies in barley leaves indicated that P23k might contribute to secondary wall formation in the leaf. In addition, we observed a marked decrease in the amount of cell wall polysaccharides and down-regulation of cellulose synthase-like CslF6 gene in P23k silenced barley. These results suggest that P23k is possibly involved in the (1,3;1,4)-β-D-glucan synthesis. We are interested in the role of P23k in the (1,3;1,4)-β-D-glucan synthesis of barley. (2) Gene expression profiling in the shoot apex of vernalized barley: The basic molecular mechanism of vernalization has been clarified with the identification of some vernalization-related genes. However, we speculate that many as-yet-unidentified genes are acting in regulating the vernalization mechanism. To identify these genes, we performed transcription profiling of genes between vernalized and un-vernalized barley. Recently we have isolated a novel candidate gene by a PCR-based HiCEP method. It may provide novel insight in understanding the vernalization mechanism of barley. |
