Extended Data Fig. 4: StTuA and StTuB overexpression increases potato plant height, chlorophyll content and N. benthamiana plant biomass.
a, Representative images of OE-StTuA, OE-StTuB and StTuA/B-RNAi transgenic and Desiree (WT) plants taken under white light, bar = 5 cm. b–d, Chlorophyll a/b content of OE-StTuA, OE-StTuB and StTuA/B-RNAi transgenic lines and control Desiree potato (n = 3 biological replicates). Data are presented as mean values +/− SEM with different asterisks refer to significant difference based on one-way ANOVA, comparing the mean of each column with the mean of the control Desiree (* P < 0.05, ** P < 0.01, *** P < 0.001, **** P < 0.0001). Bar = 1 μm. e, Representative plants and leaves of OE-StTuB N. benthamiana transgenic lines and WT (left; N. b), bar = 5 cm. f, Bar graph shows a significant biomass increase in OE-StTuB transgenic lines compared to the WT control. Data are presented as mean values +/− SEM with different asterisks refer to significant difference based on one-way ANOVA, comparing the mean of each column with the mean of the control N. b (* P < 0.05, ** P < 0.01, *** P < 0.001, **** P < 0.0001, n = 6 individual transgenic plants). Exact P values are shown in source data with 95% confidence intervals.
