| Research Abstract |
In order to clarify the mechanism of cell wall formation in woody plants under mechanical environments, the expression of genes involved in the cell wall formation was analyzed using plant cultured cells mechanically loaded. The deposition of secondary metabolic substances in their cell walls was also observed. The expression of PAL gene in the plant cultured cells was upregulated by mechanical loading for relatively short time, but didn't depend on the stress applied. Although it was impossible to determine the gene expression of some transcription factors involved in secondary cell wall formation, the expression of MYB46 and KNAT7 genes increased in the cultured cells mechanically loaded for relatively long time. Lignin was detected in the plant cultured cells subjected to a static culture after mechanical loading.
