The genome of the model plant Arabidopsis thaliana has been sequenced by an international collaboration, The Arabidopsis Genome Initiative. Here we report the complete sequence of chromosome 5. This chromosome is 26 megabases long; it is the second largest Arabidopsis chromosome and represents 21% of the sequenced regions of the genome. The sequence of(More)
There is considerable interest in the developmental, temporal and tissue-specific patterns of DNA replication in metazoans. Site-specific DNA replication at the chorion loci in Drosophila follicle cells leads to extensive gene amplification, and the organization of the cis-acting DNA elements that regulate this process may provide a model for how such(More)
The full complement of proteins required for the proper regulation of genome duplication are yet to be described. We employ a genetic DNA-replication model system based on developmental amplification of Drosophila eggshell (chorion) genes [1]. Hypomorphic mutations in essential DNA replication genes result in a distinct thin-eggshell phenotype owing to(More)
