Description

Imprecise excision of the progenitor insertion, resulting in a 498bp deletion (coordinates 2L:19768576..19769073 , release 5 genome) extending from 144bp upstream of the first bsh start codon to 72bp upstream of the second bsh start codon in the first exon, plus a 176bp insertion of unknown origin.

      In bsh1/In bsh2 mutants, there is strong disorganization of the columnar structures in the larval and pupal medulla.

      (Trush et al., 2019)

      MARCM neuron clones in the medulla that would normally express bsh (labelled using Scer\GAL4bsh.PH) but which are homozygous for bsh1 are transformed into transmedullary neuron (Tm)-type neurons in 75.9% of cases (bsh-expressing neurons normally develop into Mi1 medulla intrinsic neurons in wild-type animals).

      MARCM neuron clones in the lamina that would normally express bsh (labelled using Scer\GAL4bsh.PH) but which are homozygous for bsh1 develop into L3-like neurons in 82.9% of cases (bsh is normally expressed in L4 and L5 lamina neurons in wild-type).
