On the Evolution and Functional Significance of DNA Sequence Organization in Vascular Plants

摘要: We have investigated properties of repeated DNA sequences in vascular plants for the purposes assessing way which they may be useful to organism and probing evolution nuclear genome. In pursuit first goal we compared sequence organization both a diverse group land species within single genus. reasoned that if particular arrangement is important basic metabolic events, such as regulation gene expression, then might find common pattern among closely related perhaps distantly ones well. Regardless role genome, processes by size genome has grown during intrinsic interest. Although little experimental evidence currently available on mechanisms growth rearrangement suppose occurred, do theory from work. The proposal long blocks tandemly repeating (sometimes recognized satellite band density gradients) could periodically created serve precursor material families dispersed was made Britten Kohne 1968.
