Fig. 4From: Identification of defense related gene families and their response against powdery and downy mildew infections in Vitis viniferaRelative expression levels of PM-responsive defensive genes during PM infection and salicylic acid (SA) treatment. The fold change was calculated relative to healthy leaf samples which were assigned a value of 1. Error bars indicate the standard deviation (SD) of means. Significant differences at P < 0.001, P < 0.01, P < 0.1 have been shown with 3 (***), 2 (*) and 1 (*) asterisksBack to article page
