The gene encoding C-repeat/dehydration-responsive
element binding factor 1 (CBF1/DREB1b) of Arabidop-
sis was introduced into rice (Oryza sativa L.) under the
control of the maize ubiquitin promoter. Its incorpora-
tion and expression in transgenic rice plants were con-
firmed by DNA and RNA gel-blot analyses. Cold tol-
erance in the transgenics was not significantly differ-
ent from that of the wild-type plants, as determined by
