OsMADS26 is expressed in differentiated peripheral tissues. In situ hybridizations were revealed with the VectorBlue Kit III. Antisense (A, E, and I) and sense (B, F, and J) OsMADS26 probe hybridizations on a longitudinal section of the root tip (A and B), a transverse section in the seminal root (E and F), and a transverse section in the third leaf (I and J) of 7-d-old rice seedling. Hybridization with antisense (C, G, and K) and sense (D, H, and L) 18S ribonucleic RNA probes, which were used as positive and negative controls, respectively. abe, Abaxial epidermis; ade, adaxial epidermis; ae, aerenchyma; bds, bundle sheath; cb, bulliform cells; ep, epidermis; ex, exodermis; fib, fiber; ph, phloem; sc, sclerenchyma; st, stele; xy, xylem.
