Abstract: To dig cold tolerance genes at seedling stage of rice,based on the analysis of comparative transcriptome,TALEN genome-editing technique was constructed for BGIOSGA032296 which was down-regulated in Dongxiang wild rice seedling under cold stress.The analysis of enzyme identification and sequence alignment showed that TALEN knockout plant expression vector 1301TALEN-032296 was constructed successfully.By the agrobacterium-mediated method,the recombination clone 1301TALEN-032296 was transformed into the receptor rice variety TP309.17 transgenic rice plants were obtained.After PCR detection of hygromycin resistance gene and Fok I gene,they were found to be positive transgenic plants carrying 1301TALEN-032296.This research laid some basis for subsequent cold resistant phenotype identification.
