Figure 4From: Efficient virus-induced gene silencing in apple, pear and Japanese pear using Apple latent spherical virus vectorsVIGS of endogenous genes in apple seedlings by using ALSV vectors. (A) Leaf chlorosis of the apple seedling infected with CPN60α-ALSV (left) and normal seedling infected with wtALSV (right) (68 dpi). (B) Distortion and curling of leaves of the apple seedling infected with actin-ALSV (50 dpi). (C) Deformity of leaves in the apple seedling infected with EF-1α-ALSV (61 dpi). (D) Severe dwarfing of the apple seedling infected with EF-1α-ALSV (left) and normal apple seedling infected with wtALSV (right) (46 dpi).Back to article page
