OsSWN1 and OsSWN2 promoters are active in the tissues where secondary walls develop. (A) Neighbor-joining phylogenetic tree of OsSWN proteins and their homologous proteins in rice and Arabidopsis. The number on each branch represents percentage of bootstrap values among 1000 tests. (BG) GUS stained tissues of ProOsSWN1:GUS rice (B, D, F) and ProOsSWN2:GUS rice (C, E, G). Leaf (B, C), section of leaf (D, E) and section of culm (F, G). Bars represent 1 mm in (B) and (C), 100 μm in (D–G).
