    Detailed Description
    Statement
    Reference

    Adults transheterozygous for lncRNA:let7CKO2/lncRNA:let7CKO1 and also bearing lncRNA:let7CΔmir-let7 or lncRNA:let7CΔmir-125 exhibit a decrease in the number of pioneer α/β mushroom body neurons.

    let-7-CKO1 mutant neurons display delays in the α'/β' to p.α/β and p.α/β to α/β transitions in mushroom body neuron identities during neurogenesis, compared to wild type. Consistent with this, let-7-CKO1/let-7-CKO2 adults show an increased number of earlier born α'/&bgr' neurons, and a decreased number of later born p.α/β neurons. While the morphology of mutant mushroom bodies is grossly normal, some p.α/β and α/β axons inappropriately cross the midline.

    let-7-CKO1/+ adults show a reduction in p.α/β mushroom body neurons.

    wORF.ab3'UTR flies (in a w[-] background) whose eyes are composed exclusively of let-7-CKO1 mutant cells display a darker eye colour compared to wORF.ab3'UTR alone.

    wORF.chinmo3'UTR flies (in a w[-] background) whose eyes are composed exclusively of let-7-CKO1 mutant cells display a darker eye colour compared to wORF.chinmo3'UTR alone.

    The reduction in p.α/β mushroom body neurons in let-7-CKO1/+ adults is restored to normal numbers by chinmo1/+.
