Molecular systematics: Perfect SINEs of evolutionary history?
نویسنده
چکیده
Short interspersed repetitive elements - SINEs - are being championed as near-perfect phylogenetic characters; they have recently been used with notable success to resolve some phylogenetic conundrums, but they do have certain limitations that restrict their use as 'perfect' characters for molecular systematics.

Contribution to the molecular systematics of the genus Capoeta from the south Caspian Sea basin using mitochondrial cytochrome b sequences (Teleostei: Cyprinidae)
Traditionally, Capoeta populations from the southern Caspian Sea basin have been considered as Capoeta capoeta gracilis. Study on the phylogenetic relationship of Capoeta species using mitochondrial cytochrome b gene sequences show that Capoeta population from the southern Caspian Sea basin is distinct species and receive well support (posterior probability of 100%). Based on the tree topologie...
متن کاملThe evolutionary origin and genomic organization of SINEs in Arabidopsis thaliana.
We have characterized the two families of SINE retroposons present in Arabidopsis thaliana. The origin, distribution, organization, and evolutionary history of RAthE1 and RAthE2 elements were studied and compared to the well-characterized SINE S1 element from Brassica. Our studies show that RAthE1, RAthE2, and S1 retroposons were generated independently from three different tRNAs. The RAthE1 an...
متن کاملSINEs of the perfect character.
In their quest to reconstruct the tree of life, evolutionary biologists are constantly looking for new sources of data. Morphological data have been applied to the phylogeny problem since the 1800s, and morphology continues to be the only source of available data on relationships for the vast majority of species on Earth, past and present. However, since the 1960s, molecular data have contribut...
متن کاملSINE insertions: powerful tools for molecular systematics.
Short interspersed repetitive elements, or SINEs, are tRNA-derived retroposons that are dispersed throughout eukaryotic genomes and can be present in well over 10(4) total copies. The enormous volume of SINE amplifications per organism makes them important evolutionary agents for shaping the diversity of genomes, and the irreversible, independent nature of their insertion allows them to be used...
