- Abstract
The gene encoding C-repeat/dehydration-responsive element binding factor 1 (CBF1/DREB1b) of Arabidopsis was introduced into rice (Oryza sativa L.) under the control of the maize ubiquitin promoter. Its incorporation and expression in transgenic rice plants were confirmed by DNA and RNA gel-blot analyses. Cold tolerance in the transgenics was not significantly different from that of the wild-type plants, as determined by ion leakage, chlorophyll fluorescence, and survival rates. However, the cold-responsive genes lip5, lip9, and OsDhn1 were up-regulated in the transgenic plants, suggesting that the cold signal transduction pathway involving CBF1 is partially conserved in this cold-labile plant.
