A Gene Family Derived from Transposable Elements during Early Angiosperm Evolution Has Reproductive Fitness Benefits in Arabidopsis thaliana
The benefits of ever-growing numbers of sequenced eukaryotic genomes will not be fully realized until we learn to decipher vast stretches of noncoding DNA, largely composed of transposable elements. Transposable elements persist through self-replication, but some genes once encoded by transposable elements have, through a process called molecular domestication, evolved new functions that increa...
متن کاملArchaefructaceae, a new basal angiosperm family.
Archaefructaceae is proposed as a new basal angiosperm family of herbaceous aquatic plants. This family consists of the fossils Archaefructus liaoningensis and A. sinensis sp. nov. Complete plants from roots to fertile shoots are known. Their age is a minimum of 124.6 million years from the Yixian Formation, Liaoning, China. They are a sister clade to all angiosperms when their characters are i...
متن کاملMUSTANG is a novel family of domesticated transposase genes found in diverse angiosperms.
While transposons have traditionally been viewed as genomic parasites or "junk DNA," the discovery of transposon-derived host genes has fueled an ongoing debate over the evolutionary role of transposons. In particular, while mobility-related open reading frames have been known to acquire host functions, the contribution of these types of events to the evolution of genes is not well understood. ...
متن کاملSite-specific recombination by the DDE family member mobile element IS30 transposase.
DNA rearrangements carried out by site-specific recombinases and transposases (Tpases) show striking similarities despite the wide spectrum of the catalytic mechanisms involved in the reactions. Here, we show that the bacterial insertion sequence (IS)30 element can act similarly to site-specific systems. We have developed an inversion system using IS30 Tpase and a viable lambda phage, where the...
