From: Comparative genomic analysis of the WRKY III gene family in populus, grape, arabidopsis and rice
qRT-PCR expression levels of selected PtrWRKY genes following SA (100uM), and different tissues. The Y-axis indicates the relative expression levels; 0, 1, 3, 6, 9, 12, and 24 (X-axis) indicate hours of treatment. Mean values and standard deviations (SDs) were obtained from three biological and three technical replicates. a Expression patterns of WRKY III genes from Populus in various tissues. R, roots; YL, young leaves; ML, mature leaves; ST, stems; X, xylem; Phl, phloem. b Expression levels of selected PtrWRKY genes under SA treatment. Horizontal discontinuous lines marks the 1.0 value
