Abstract: 【Objective】 Analysis of Gene Family in the Solanum pennellii. 【Methods】 In this study, the whole genome of Pannellii GRF gene family members was identified and analyzed based on bioinformatics methods, and its origin and evolution were traced. 【Result】 Ten SpGRF members were identified in S.pennellii tomato, and they were unevenly distributed on seven chromosomes.The physical and chemical properties such as molecular weight, isoelectric point and total hydrophilic mean of SpGRFs protein were predicted.The phylogenetic tree showed that SpGRFs gene could be divided into six subfamilies.All SpGRF genes contained a QLQ and a WRC domain at the N-terminal and several conserved motifs at the C-terminal.The results of collinearity showed that there were three pairs of six paragenetic homologous genes in the genome, all of which were fragment replication.Under the pressure of natural selection, SpGRFs had a common ancestor, which was closer to Arabidopsis. 【Conclusion】 This study successfully identifies the basic information of GRF gene family in S.pennellii, which has laid a theoretical foundation for explaining the function of GRF family and the mining of wild tomato gene resources.
