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 ...
متن کاملWingless degradation in Drosophila imaginal discs
Wingless is a secreted signalling molecule with multiple roles in patterning developing Drosophila. Previous work has shown that in the Drosophila embryonic epidermis, regulated degradation controls the distribution of Wingless protein, leading to an asymmetric range. The actual mechanism of Wingless degradation is not currently understood. I have used gain and loss of function experiments to e...
متن کاملSignaling Reaches to New Dimensions in Drosophila Imaginal Discs
Finding that peripodial cells in wing and eye imaginal discs are essential for the growth and patterning of the separate layer of disc cells now opens the study of interacting cell layers to the powerful developmental genetic techniques with which the Drosophila system is blessed. We can anticipate that future work will identify how such interactions contribute to patterning and how the mechani...
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...

the satellite cells. Contaminating CD45+/Mac-1+/Sca-1+ cells were subsequently removed by MACS cell separation. Cell cycle analysis revealed that over 80% of the resulting myogenic cell population was in G0, indicating a high proportion of quiescent cells in the isolated population. RT-PCR analysis showed that the expression of three Kruppel-like factors (Klf) was increased in quiescent satelli...
