To thy proteins be true: RNA editing in plants.
Plastid and mitochondrial genomes encode for a certain percentage of their own proteins. Which ones and the number of genes are species dependent. The remainder of the proteins are encoded by the nucleus and imported posttranslationally into the organelle.Asplastids arederived fromacyanobacterial ancestor, gene expression exhibits a hybrid of prokaryote and eukaryote features, with nuclear-enco...

متن کاملThelytokous parthenogenesis in eusocial Hymenoptera.
Female parthenogenesis, or thelytoky, is particularly common in solitary Hymenoptera. Only more recently has it become clear that many eusocial species also regularly reproduce thelytokously, and here we provide a comprehensive overview. Especially in ants, thelytoky underlies a variety of idiosyncratic life histories with unique evolutionary and ecological consequences. In all eusocial species...
متن کاملFacultative parthenogenesis discovered in wild vertebrates.
Facultative parthenogenesis (FP)-asexual reproduction by bisexual species-has been documented in a variety of multi-cellular organisms but only recently in snakes, varanid lizards, birds and sharks. Unlike the approximately 80 taxa of unisexual reptiles, amphibians and fishes that exist in nature, FP has yet to be documented in the wild. Based on captive documentation, it appears that FP is wid...
