The synchronous development of a sibling group of Rhynchosciara larvae enables us to follow the relationship between the local transcription and extrareplication of C3 and C8 DNA puffs. Although DNA amplification at these two loci takes place during the last cycle of DNA duplication in salivary gland chromosomes, a different timing of puff expression was(More)
Cyclic lipopeptides are produced by a soil Bacillus megaterium strain and several other Bacillus species. In this work, they are detected both in the Bacillus intact cells and the cells culture medium by MALDI-TOF mass spectrometry. The cyclic lipopeptides self-assemble in water media producing negatively charged and large aggregates (300-800 nm of mean(More)
