Schematic representations of the vectors used to modify TaZFP1B expression in wheat. a Vectors of the four-component BSMV system used for overexpression. b Vectors of the three-component BSMV system used for silencing. c Quantification of TaZFP1B transcripts in wheat. Wild-type, uninfected Atlas 66 plants; Empty-vector, Atlas 66 plants infected with the four basic (“empty”) plasmids: pCaBS-α, pCaBS-β, pCaBS-γ1:00 and pCaBS-γ2:00; 1B-OEX, Atlas 66 plants infected with the four plasmids described in (a); 1B-siRNA, Atlas 66 plants infected with the three plasmids described in (b). Values are means ±SD of four biological replicates. Different letters indicate statistically significant differences between samples (P < 0.05 by Tukey’s test)
