Neuronal identity of antennal cells expressing LmigORs. a–b, The labelling pattern of LmigOR1 (a) and LmigORco (b) antisense probe on consecutive sections of locust antenna. c–d, The labelling pattern of LmigORco (c) and LmigOR2 (d) antisense probe on consecutive sections of locust antenna. e–f, Illustration of occasionally labelled dendritic like structures (indicated by red arrows). g, Two-colour in situ hybridization was performed on longitudinal antennal sections to illustrate the expression of LmigOR1 (Red) and LmigORco (Green). Localization of LmigOR1 expressing cells in cell clusters expressing LmigORco confirmed its neural identity. h, Close view of boxed areas in g. Occasionally labelled dendritic like structures were indicated by arrow. Circled areas indicate ORNs cluster expressing LmigORco and sharing the same sensillum. Scale bar: a–d, g: 50 μm; e, f, h: 20 μm.
