The SWEET(sugar will eventually be exported transporter)family proteins are a recently identiﬁed class of sugar transporters that are essential for various physiological *** the functions of the SWEET proteins have been identiﬁed in a number of species,to date,there have been no reports of the functions of the SWEET genes in woodland strawberries(Fragaria vesca).In this study,we identiﬁed 15 genes that were highly homolo-gous to the *** AtSWEET genes and designated them as FvSWEET1–*** then conducted a structural and evolutionary analysis of these 15 FvSWEET *** phylogenetic analysis enabled us to categor-ize the predicted 15 SWEET proteins into four distinct *** observed slight variations in the exon‒intron structures of these genes,while the motifs and domain structures remained highly ***,the developmental and biological stress expression proﬁles of the 15 FvSWEET genes were extracted and ***,WGCNA coexpression network analysis was run to search for possible interacting genes of FvSWEET *** results showed that the FvSWEET10 genes interacted with 20 other genes,playing roles in response to bacterial and fungal *** outcomes of this study provide insights into the further study of FvSWEET genes and may also aid in the functional characterization of the FvSWEET genes in woodland strawberries.
