Abstract Background Virus-like particle (VLP) platform represents a promising approach for the generation of efficient and immunogenic subunit vaccines. Here, the feasibility of using grapevine fanleaf virus (GFLV) VLPs as a new carrier for the presentation of human papillomavirus (HPV) L2 epitope was studied. To achieve this goal, a model of the HPV L2 epitope secondary structure was predicted and its insertion within 5 external loops in the GFLV capsid protein (CP) was evaluated. Results The epitope sequence was genetically inserted in the αB-αB” domain C of the GFLV CP, which was then over-expressed in Pichia pastoris and Escherichia coli. The highest expression yield was obtained in E. coli. Using this system, VLP formation requires a denaturation-refolding step, whereas VLPs with lower production yield were directly formed using P. pastoris, as confirmed by electron microscopy and immunostaining electron microscopy. Since the GFLV L2 VLPs were found to interact with the HPV L2 antibody under native conditions in capillary electrophoresis and in ELISA, it can be assumed that the inserted epitope is located at the VLP surface with its proper ternary structure. Conclusions The results demonstrate that GFLV VLPs constitute a potential scaffold for surface display of the epitope of interest.

During a survey in 2011–2012, three ornamental plants of Araceae namely Aglaonema nitidum, Syngonium podophyllum and Dieffenbachia amoena showing foliar disease symptoms were collected from central region of Iran. Infected plants exhibited spots on their leaves which appeared as yellow and water-soaked with chlorotic haloes and necrotic center. To investigate the etiology of this disorder, symptomatic leaves were collected from affected plants and six bacterial strains (B2Y, J3Y, SY, E60Y, E68Y and E5MM) were isolated and identified as Pantoea ananatis or P. agglomerans based on morphological, physiological, biochemical and molecular characters. The pathogenicity tests of the isolates demonstrated that they were not host specific. Furthermore, 16S rRNA gene sequencing revealed that the strains were phylogenetically closely related to genus Pantoea. Multilocus sequence analysis (MLSA) of concatenated partial atpD, gyrB and rpoB gene sequences of the six isolates showed a high similarity of B2Y, J3Y, and SY strains to P. ananatis and also of E60Y, E5MM and E68Y strains to P. agglomerans. These results were confirmed by phylogenetic analysis. To the best of our knowledge, this is the first report of leaf spot and necrosis of A. nitidum, S. podophyllum and D. amoena caused by the genus Pantoea.
