Effect of PsnSHN2 overexpression on the secondary wall thickness in the stems of PsnSHN2 transgenic lines. (A) Three-month-old wild-type (left) and PsnSHN2 transgenic lines (middle and right). (B) The expression levels of PsnSHN2 in transgenic lines. Error bars represent SD of three biological replicates. (C–F) The scanning electron microscope of cross stem sections of wild-type (C,E) and PsnSHN2 transgenic lines (D,F). (G) The secondary wall thickness of cross stem sections of PsnSHN2 transgenic lines. Error bars represent SD of three biological replicates. Asterisks indicate levels of significance (t test; *P < 0.05, **P < 0.01).
