Systemic Colonization of Strain YL19 Causing Dry Cavity Rot of Strawberry Crown Tissue in China.

usually causes angular leaf spot (ALS) of strawberry, a serious bacterial disease in many strawberry-producing regions worldwide. Recently, a new strain of (YL19) was isolated from strawberry in China and has been shown to cause dry cavity rot in strawberry crown. In this study, we constructed a green fluorescent protein (GFP)-labeled YL19 (YL19-GFP) to visualize the infection process and pathogen colonization in strawberries.
