| Research Abstract |
We investigated changes in the expression levels of genes related to sucrose metabolism and transport in tissues of booting-stage rice exposed to a chilling temperature. Decrease in sucrose content in primitive panicles of rice was observed at 12℃. The gene expression analysis suggested that expression levels of OsSUT and OsSUS, OsINV might be related to changes in sucrose metabolism and partitioning in rice plants under a cold condition. Contents of glucose and fructose were higher in sink tissues. The contents were also higher in fructan-acumulated rice than in non-transgenic rice. These results might be due to the release of monosaccharides during induced fructan synthesis or degradation in transgenic rice.
