      Detailed Description
      Statement
      Reference

      Arl2Δ309/Arl2Δ309 clones have extra neuroblasts in both type I and II neuroblast lineages, compared to a single neuroblast in control clones (third instar larval central brain). Wild type interphase neuroblasts contain one major microtubule aster organized by the centrosome, whereas Arl2Δ309/Arl2Δ309 clones do not organize an aster and metaphase neuroblasts do not assemble mitotic spindle.

      Co-expression of Arl2WT.Scer\UAS and COX7AScer\UAS.cCa driven by Scer\GAL4tub.PU rescues embryonic lethality in Arl2Δ309/Arl2Δ309 mutants.

      Arl2Δ309 is partially rescued by Scer\GAL4insc.PU/Arl2WT.UAS

      (Chen et al., 2016)
      Comments

      Expression of Arl2WT.Scer\UAS rescues the phenotype of extra neuroblasts in both type I and II neuroblast lineages seen in Arl2Δ309/Arl2Δ309 clones (Scer\GAL4insc.PU).
