Genome organization in higher plants
Metadata[+] Show full item record
Higher plant chromosomes contain many families of thousands of similar nucleotide sequences as well as sequences pre sent in only one or a few copies per haploid genome. We summarise here biochemical investigations into the linear chromosomal organisation of the different kinds of repeated and non-repeated sequences in the DNA of wheat. Some models of the fine structure organisation of common sequence arrangements are presented. The possible roles of these sequence arrangements in gene expression and chromosome behaviour are discussed.
