The CBF1 gene fromSolanum lycopersicoides and Lycopersicon habrochaites was transferred into tobacco(Nicotiana tobacum L.)by agrobacterium-mediated leaf disc method.The transcriptomic differences of transgenic tobacco under low temperature stress were studied.The results showed that under low temperature stress,the low temperature tolerance of transgenic tobacco was higher than that of the wild type when the transgenic tobacco was under low temperature stress.Both SlCBF1 and LhCBF1 genes were overexpressed ...
