In situ hybridization of OS-ACS5 mRNA in air-grown deepwater rice seedlings (9 d). The hybridization signal is seen as bright-white spots. A, Longitudinal stem section; B through E, transverse sections of nonelongating stem and leaf sheaths at indicated positions; F, magnification of apex seen in A; G, magnification of adventitious root primordium seen in A. A, Shoot apex; AP, adventitious root primordium; AR, adventitious root; CN, coleoptile node; IL, imperfect leaf; IN, imperfect leaf node; L1 and L2, leaves; N1 and N2, corresponding nodes; VB, vascular bundle.
