The effects of NtTTG2 overexpression on main characters of tobacco development. (a) Forty-day-old plants. (b) Real-time RT-PCR analyses of EXP1 and EXP2 expression in leaves of plants from (a). (c) The biomass of plants from (a). (d) S5 flowers and mature seeds. (e) S5 flower anthocyanin content given as relative unit (r.u.). (f) The number of seeds per mature fruit. Quantitative data are presented as mean values ± SD bars of results from five experimental repeats each involving 15 plants (b, c), 30 flowers (e), or 30 fruits (f). Different letters on curve and bar graphs indicate significant (P < 0.01) differences by one-way ANOVA and LSD test.
