Root anatomy of rice cultivars resistant [‘Dawn’ = (a–d)] and susceptible [(‘BRS Pampa CL’ = (e–g)] to the South American rice water weevil Oryzophagus oryzae at 25 Days After Flooding (DAF). (a), (e) Overview, box showing the differentiation among root layers; (b), (f) Sclerenchyma cells arranged into 3-layers and 1-layer in the resistant and susceptible cultivars, respectively; (c), (d) and (g) Lignin detection in sclerenchyma cells by histochemical methods (red color) [(c) ‘Dawn’ infested plant and (d) ‘Dawn’ non-infested plant]. AP = aeriferous parenchyma or aerenchyma; Ep = epidermis; Ex = exodermis; En = endodermis; Sc = sclerenchyma; X = xylem; P: phloem Bars: 200 µm.
