Article Title: Continuous cell lines derived from the Asian citrus psyllid, Diaphorina citri, harbor viruses and Wolbachia

doi: 10.1038/s41598-024-83671-2

Figure Lengend Snippet: PCR of Wolbachia ftsz and wsp confirms the presence of Wolbachia in Dici1 and Dici5, but not Dici3 cells. ( A ) Partial fragments of Wolbachia ftsz (1043 bp) and wsp (570 bp) were amplified from Dici1 (Passage 27, GenBank: PP894982 for ftsz and PP894984 for wsp ) and Dici5 (Passage 33, GenBank: PP894983 for ftsz and PP894985 for wsp ), but not Dici3 (Passage 46), genomic DNA. NTC: no template control. Arrows indicate PCR products at the expected sizes. GeneRuler 1 kb plus DNA ladder (ThermoFisher Scientific, SM1332) was used as a DNA marker. Two weeks of doxycycline treatment reduced the levels of ftsz and wsp in Dici1 ( B ) and Dici5 ( C ) cells.

Figure Lengend Snippet: Evaluation of viral infection status in Diaphorina citri cell lines. ( A ) DcRV RT-PCR confirms the presence of this reovirus in Dici1, but not Dici3 cells. Partial fragments (900 bp) of the DcRV p8 were amplified from the cDNA of Dici1 (P1, GenBank: PP894986), but not Dici3 (P5). ( B ) RT-PCR confirmed the presence of DcACV and DcRV in Dici5 cells. Partial fragments of the DcACV RNA1 (473 bp, GenBank: PP894988) and DcRV p8 (GenBank: PP894987) were amplified from the cDNA of Dici5 (Passage 33). GeneRuler 1 kb plus DNA ladder was used as a DNA marker. + control: cDNA made from purified D. citri viruses. NTC: no template control. Arrows indicate PCR products at the expected sizes.
