Genomic regulatory blocks are chromosomal regions spanned by long clusters of highly conserved
noncoding elements devoted to long-range regulation of developmental genes, often immobilizing
other, unrelated genes into long-lasting syntenic arrangements. Synorth synorth.genereg.net
is a web resource for exploring and categorizing the syntenic relationships in genomic regulatory
blocks across multiple genomes, tracing their evolutionary fate after teleost whole genome
duplication at the level of genomic regulatory block loci, individual genes, and their phylogenetic
context.
