      egg chamber & mitotic cell cycle

      (Lilly et al., 2000)
      Detailed Description
      Statement
      Reference

      Expression of homozygous CycBΔ.T:Ivir\HA1 at the permissive temperature prevents or severely delays cell cycle progression at early anaphase.

      (Baldinger and Gossen, 2009)

      When CycBΔ.T:Ivir\HA1 is over-expressed in adult females germline cysts with an aberrant number of cells are produced. Cysts containing 32 instead of 16 cells are seen in 5.9% of egg chambers.

      (Lilly et al., 2000)

      Expression blocks cell cycle progression after entry into mitosis, predominantly early anaphase figures are seen (before sister chromosome separation).
