Abstract:

In order to explore the interaction between ScPRT1 and Sporisorium scitamineum genes in sugarcane,this study used Saccharum spontaneum and Saccharum as research objects.The ScPRT1(GenBank Accession Number:MT747433)gene was cloned by RT-PCR and was analyzed by bioinformatics,quantitative Real-time PCR and subcellular localization.Bioinformatics analysis showed that the full-length cDNA of the ScPRT1 gene was 1 621 bp,including a complete open reading frame with 1 260 bp in length and encodes 419 amino acids.The ScPRT1 protein with two RING domains and one ZZ domain,was 46.56 ku in molecular weight and was an acidic and unstable hydrophilic protein with nuclear localization signal and no signal peptide.The higher structural elements of protein were mainly random coil.The results of qRT-PCR analysis showed that ScPRT1 was higher expressed in stem pith than in bud,epidermis and leaf.And ScPRT1 was significantly up-regulated under abscisic acid(ABA)stress and in the smut-resistant variety but significantly down-regulated in the smut-susceptible variety under Sporisorium scitamineum stress.The result of subcellular localization showed that ScPRT1 was localized in the nucleus.In the co-expression network between ScPRT1 and Sporisorium scitamineum genes,three genes that encoded effectors with aromatic amino acid residues at the N-terminal were found co-expressing with ScPRT1,and their proteins may interact directly.It is speculated that ScPRT1 plays an important role in sugarcane hormone signal transduction and response to smut infection.
