Abstract: A series of gene’s expression and silencing were involved in potato tuber formation. The full length of potato STI-LIKE gene was cloned by using the RT-PCR(reverse transcription PCR)method from the potato variety “Atlantic”. The expression of STI-LIKE gene in all potato organs were analyses by real time PCR analysis. The results showed that STI-LIKE gene expressed in all potato organs. The bioinformatics analysis indicated that STI-LIKE protein contains three TPR domains, and the STI-LIKE gene was homologous recombination in higher plants. The expression vector(pBI121)and interference vectors(pHANNIBAL and pART27)were constructed and transferred to Arabidopsis thaliana. The STI-LIKE protein expression level was examined by Western blot with specific antibody. The results indicated that STI-LIKE gene might be associated with the growth and development of seedling of Arabidopsis.
