The expression level of TaWD40-4B.1 C and TaWD40-4B.1 T in transgenic lines of cultivars YM20 (n = 4 biologically independent samples; P = 1.45 x 10 -14 in a and 1.07 x 10 -11 in b ). In a , b , data are shown as mean and standard deviation; In e j , the box indicates the range from lower to upper quartiles, and the bar ranges the minimum to maximum observations. The significance of the difference is calculated with a one-way ANOVA analysisTukey comparison and the columns labeled without the same alphabet are significantly different ( P < 0.05, two-sided). SR3 and YM20: two cultivars carrying TaWD40-4B.1 C and TaWD40-4B.1 T , respectively; OE-T: TaWD40-4B.1 T overexpression lines; OE-C: TaWD40-4B.1 C overexpression lines; RNAi: TaWD40-4B.1 C / TaWD40-4B.1 T RNAi lines.
