WebAbstract. Analysis of Caenorhabditis elegans syp-1 mutants reveals that both synapsis-dependent and -independent mechanisms contribute to stable, productive alignment of homologous chromosomes during meiotic prophase. Early prophase nuclei undergo normal reorganization insyp-1 mutants, and chromosomes initially pair. However, the polarized … WebIn Gram-negative bacteria, the best-studied quorum-sensing signals are acyl-homoserine lactones (AHLs), which are synthesized by LuxI homologs using SAM as substrate and are detected by LuxR-homolog receptors. The first LuxI-LuxR pair was described in Vibrio spp., but it was rapidly shown to be widespread in Proteobacteria.
