| Popis: | In the homoeotic bithorax mutant combination bx3 pbx Ubx 105 of Drosophila melanogaster, the metathoracic segment is transformed to a mesothoracic segment and the adult flies have an extra pair of wings in place of the paired halteres [Lewis, E. B. (1963). Amer. Zool.3, 33–56]. The morphology of the larval fat body, the number of cells in the fat body, and the distribution pattern of kynurenine autofluorescent materials (KAF+) in this tissue were compared in the homoeotic mutant and a wild-type strain. The mutant has an additional mass of adipose cells anterior to the posterior margin of the ventral commissure of the fat body. However, the total number of adipose cells in the two strains as well as the limits of the KAF+ cell population do not differ. Therefore, the bithorax transformation in the larval fat body involves rearrangement of the same cell population as that in the normal strain. This study suggests (1) that the bithorax mutant genes affect the pattern of cell segregation and/or migration of preblastoderm nuclei during embryogenesis and (2) that the larval fat body of Drosophila has a segmental origin. |
