General Information
Term imaginal disc primordium ID (Ontology) FBbt:00001649 (Fly Anatomy)
Definition Population of contiguous, morphologically distinct cells of the embryo that will proliferate to form an imaginal disc in the larva. During early embryogenesis the precursor is part of the epithelial sheet before segregating from the epithelial sheet by late embryogenesis (Cohen, 1993).[ FlyBase:FBrf0064789 ]
