The early development of mesothoracic compartments in Drosophila

摘要: Abstract The results from three methods of studying the cell lineage early Drosophila development are reported: clonal analysis, Minute technique, and gynandromorph fate mapping. We conclude that by about one division after blastoderm anterior posterior groups cells in mesothorax separated, as generate different segments. Clones produced irradiation eggs aged 4 ± 2 hr do cross wing to leg, so these two discs share a common origin until at least divisions blastoderm. number epidermal disc newly hatched larva is estimated 20 cells. Gynandromorph mapping discussed detail. It concluded sturt distances between landmarks not only determined distance apart their progenitor blastoderm, but strongly dependent on compartmentalisation other aspects postembryonic development. consequences this discussed. discuss evidence may be adjacent
