See sections below for more information
The gene morula is referred to in FlyBase by the symbol mr (CG3060, FBgn0002791). It has the cytological map location 60A15. Its sequence location is 2R:19859956..19862935. Its molecular function is described as ubiquitin protein ligase binding. It is involved in the biological processes: mitotic anaphase; negative regulation of synaptic growth at neuromuscular junction; regulation of synaptic transmission; regulation of cell cycle; ubiquitin-dependent protein catabolic process. 14 alleles are reported. The phenotypes of these alleles are annotated with 16 unique terms, many of which group under: organ system; anatomical structure; nervous system; egg; peripheral nervous system; adult; germ cell; nuclear part; cell cycle; endocrine system; spindle; adult segment. It has one annotated transcript and one annotated polypeptide.

mr: morula
thumb
mr: morula
Eyes rough. Bristles irregularly reduced in size and number. Abdominal sclerites often smaller. Developmental study by Lees and Waddington [1942, Proc. Roy. Soc. (London), Ser. B 131: 87-100] shows that effect on bristles results from general slowing of bristle growth. Female entirely sterile, has underdeveloped ovaries. At 19, bristles nearly normal and eyes nearly wild type. RK2 at 25 and above.
mr2
Less extreme than mr. Nearly wild type at 19. Female entirely sterile. Oogenesis normal through stage 4; then compound nurse cell chromosomes fall apart and degenerate. Karyosome of oocyte also disappears. Oogenesis does not proceed beyond sixth stage (King, 1964, Royal Entomol. Soc. London Symposium 2, Insect Reproduction, pp. 13-25). RK2 at 25 or above.

            mr is required for the maintenance of endomitosis in the nurse cells of the adult female ovary. Nurse cells of hypomorphic alleles revert to a mitotic-like state instead of going on to become highly polyploid.
