ICE1 genes play a very important role in plants in cold conditions. To improve the cold resistance of tomato, the ICE1 gene of Arabidopsis thaliana was used to construct the plant expression vector p3301-ICE1, and was overexpressed in tomato through Agrobacterium-mediated transformation. Five strains of resistant plants were obtained. PCR and half-quantitative results showed that the ICE1 gene was transferred to tomato; three strains tested positive. After low-temperature stress treatment, praline content and peroxide and catalase activities in the transgenic tomato plants were higher compared with non-transgenic controls, while malondialdehyde content was clearly lower. © FUNPEC-RP.
