Differential gene expression during cold acclimation was studied by mRNA differential display reverse transcription-PCR (DDRT-PCR) in tea plant (Camellia sinensis). Twenty-three differentially expressed cDNA fragments were steadily re-amplified. Five fragments were confirmed by RT-PCR analysis. Among them, three were up-regulated while other two were down-regulated during the cold acclimation process. Sequencing of three differential fragments revealed homology to putative cis-zeatin-O-glucosyl-transferase of Sorghum （Sorghum bicolor）, chloroplast gene for chloroplast product of cucumber(Cucumis sativus),ribulose-1,5-bisphosphate carboxylase/oxygenase small subunit (rbcS) mRNA of tea plant(Camellia sinensis), respectively, while the other two showed no homologous to known genes.
