a Phenotypes of Gala-3 (GL-3) and MdMIPS1-RNAi apple lines under greenhouse conditions. b, c Assay results of MI depletion. Toluidine blue O staining of longitudinal sections of a shoot tip d and root e and cross-sections of a leaf f from GL-3 and Ri-2 under MI-depleted MS medium. MS control and MI depletion represent normal and MI-depleted MS media, respectively; le leaf, ad apical dome, lp leaf primordium, st stem, rc root cap, e epidermis, c cortex, le lower epidermis, p parenchyma, ph phloem, pl palisade cell, s spongy mesophyll, ue upper epidermis, v vessel, and x xylem. Bars = 200 μm d, 100 μm (e and f for GL-3), and 50 μm (e and f for Ri-2). The arrow indicates necrosis.
