Objective: To clone squalene synthase gene( ss) from seeds of Citrus reticulata‘Dahongpao',and to analyze its expression and bioinformatics. Methods: The technology of RT-PCR was used to clone the gene of Citrus reticulata seeds and analyze its expression at various growing stages. Moreover,the bioinformatics was analyzed by online analytical tools. Results: The full-length of ss was1 205 bp and 397 amino acids were encoded,SS had a homology of 99% with that of Citrus sinensis and Citrus clementina. The gro...
