Delay of overripe fruit abscission and morphological structure of AZs in SlP4H3 RNAi lines. (A) Final stage of abscission of a wild type overripe fruit 90 days after breaker. Representative AZs of overripe fruits 90 days after breaker in the three SlP4H3 RNAi lines #1, #6, and #7. The arrows point to the AZ. (B) Longitudinal sections of petiole AZs at the stage of open flower in the SlP4H3 RNAi lines and wild type. The dotted-line contour defines the abscission zone based on the visible separation layer. The blue line represents 1 mm.
