Developmental behaviour of fragments of symmetrical and asymmetrical imaginal discs of Drosophila melanogaster (Diptera).
Earlier experiments have demonstrated a very high 'regulative' ability in the genital disc of Drosophila melanogaster. Medially sectioned discs, even from mature larvae, are able to form a fully differentiated normal genital apparatus if the fragments are cultured in vivo in a larval host for a sufficient length of time before metamorphosis. Even a quarter of a disc has this 'regulative' abilit...
متن کاملDissection and immunostaining of imaginal discs from Drosophila melanogaster.
A significant portion of post-embryonic development in the fruit fly, Drosophila melanogaster, takes place within a set of sac-like structures called imaginal discs. These discs give rise to a high percentage of adult structures that are found within the adult fly. Here we describe a protocol that has been optimized to recover these discs and prepare them for analysis with antibodies, transcrip...
متن کاملBiogenesis of Golgi stacks in imaginal discs of Drosophila melanogaster.
We provide a detailed description of Golgi stack biogenesis that takes place in vivo during one of the morphogenetic events in the lifespan of Drosophila melanogaster. In early third-instar larvae, small clusters consisting mostly of vesicles and tubules were present in epithelial imaginal disk cells. As larvae progressed through mid- and late-third instar, these larval clusters became larger b...
متن کاملEcdysteroid receptors in imaginal discs of Drosophila melanogaster.
[3H]Ponasterone A (PNA) of high specific activity has been used to identify and begin characterization of ecdysteroid (formerly called ecdysone) receptors in cytoplasmic and nuclear fractions of imaginal discs of Drosophila melanogaster. The equilibrium Kd of the observed macromolecular binding, 3--4 X 10(-9) M PNA, is in good agreement with the minimal concentration required for induction of c...

and clatter. The Italians call them buffone — clowns. The large white grubs feed on roots and can be a major pest of grass and potatoes. Now controlled by pesticides, they were once far more abundant locally. In 1574, adult cockchafers were so numerous in the Severn Valley that their drowned bodies blocked the wheels of watermills, the book describes. In parts of Europe, if not in Britain, the ...
