Male sterility in CsGAMYB1 transgenic plants with high levels of CsGAMYB1 in Arabidopsis. (A and B) Flowers of Col (A) or CsGAMYB1 overexpression (B). (C) Stamens in Col (left) or CsGAIP overexpression (right). (D) Inflorescences of Col (left) or lines of CsGAMYB1 overexpression (middle and right). (E) Opened siliques of Col (left) or CsGAMYB1 overexpression (right). Bar=1mm, except D, in which the bar=1cm. (F) Fertility in Col and 8 selected CsGAMYB1 transgenic lines. The fertility is defined as the percentage of siliques that set seeds per plant. Error bars indicate the standard errors. (G) qRT-PCR analyses of CsGAMYB1 in eight selected transgenic lines in the Col background. The Arabidopsis actin2 was used as an internal control, and these experiments were repeated in three independent samples. Error bars indicate the standard errors.
