During embryogenesis, the beta 3 tubulin gene of Drosophila is transcribed predominantly in the mesoderm. We have raised antibodies specific to the C-terminal domain of the beta 3 tubulin and analysed by immunostaining the distribution of this tubulin isotype during Drosophila embryogenesis. The protein is first detectable in the cephalic mesoderm at maximal germband extension. Shortly afterwards, beta 3 tubulin is expressed in single cells at identical positions of the thoracic and abdominal segments. We suggest that these cells represent muscle pioneer cells of Drosophila. During later embryonic development the somatic musclature, visceral musculature, dorsal vessel and macrophages contain beta 3 tubulin. In dorsalizing mutants dorsal, snail and twist, which do not form a ventral furrow during gastrulation, beta 3 expression is greatly reduced but not completely abolished. Our analysis shows that beta 3 tubulin immunostaining characterizes the differentiation of mesodermal derivatives during embryogenesis.
