Fig. 2From: Effect of two digestive enzymes and pH on the dsRNA of endornaviruses of bell pepper and melon under in vitro conditionsAgarose gel electrophoresis of dsRNA extracted from bell pepper and melon fruit tissues infected with bell pepper endornavirus (BPEV) and Cucumis melo endornavirus (CmEV), respectively. Before dsRNA extraction, tissues were macerated and incubated for 2 h at 37 °C at different pH values. Lane 1, 1-kb marker; lane 2, BPEV pH 3.0; lane 3, CmEV pH 3.0; lane 4, BPEV pH 1.0; lane 5, CmEV pH 1.0; lane 6, BPEV pH 4.0; lane 7, CmEV pH 4.0; lane 8, BPEV pH 2.0; and lane 9, CmEV pH 2.0. DsRNA sample load consisted of 25 μL. Arrow indicates the relative position of dsRNAsBack to article page
