In situ hybridization of the ZmCNGT gene transcript on the central longitudinal sections of developing caryopsis at 11 DAP. (A) Upper part of caryopsis; (B) close-up of embryo region; (C) basal endosperm, P-C layer and pedicel; (D) control reaction with the antisense probe. The visible area is represented by the red rectangles in the schematic caryopsis drawings. Abbreviations: BETL, basal endosperm transfer layer; em, embryo; en, endosperm; pr, pericarp; P-C, placento-chalaza; s, scutellum; v, vascular tissue.
