DNA replication and cell cycle in plants: learning from geminiviruses.
Plant cell growth and development depend on continuous cell proliferation which is restricted to small regions of the plant called meristems. Infection by geminiviruses, small DNA viruses whose replicative cycle relies on host cell factors, is excluded from those proliferating areas. Since most of the replicative factors are present, almost exclusively, in proliferating cells, geminivirus infec...
متن کاملHerpes simplex virus: selection of origins of DNA replication.
A selection procedure was devised to study the role of cis -acting sequences at origins of DNA replication. Two regions in Herpes simplex virus oriS were examined: an AT-rich spacer sequence and a putative binding site, box III, for the origin binding protein. Plasmid libraries were generated using oligonucleotides with locally random sequences. The library, amplified in Escherichia coli , was ...
متن کاملDNA replication origins in archaea
DNA replication initiation, which starts at specific chromosomal site (known as replication origins), is the key regulatory stage of chromosome replication. Archaea, the third domain of life, use a single or multiple origin(s) to initiate replication of their circular chromosomes. The basic structure of replication origins is conserved among archaea, typically including an AT-rich unwinding reg...
متن کاملSnapShot: Origins of DNA Replication
The fundamental unit of DNA replication, the replicon, is governed by a cis-acting replicator sequence and a trans-activating initiator factor. Despite the increased size and complexity of eukaryotic genomes, eukaryotic DNA replication continues to be guided by the fundamental principles and concepts established in the replicon model.
متن کاملDNA replication: the unbearable lightness of origins.
Now that the genomes of various metazoans have been sequenced, one of the biggest challenges in biology is to understand their functional organization. Programmed alterations of gene expression during development and cell differentiation frequently involve long-range modifications in the organization of chromosomal loci. These modifications include nuclear localization, genetic locus conformati...
