An evolutionary analysis of orphan genes in Drosophila.
Orphan genes are protein-coding regions that have no recognizable homolog in distantly related species. A substantial fraction of coding regions in any genome sequenced consists of orphan genes, but the evolutionary and functional significance of orphan genes is not understood. We present a reanalysis of the Drosophila melanogaster proteome that shows that there are still between 26% and 29% of...
متن کاملEvolutionary Origin of Orphan Genes
Orphangenes aregenes thatoccur in specific evolutionary lineages without similarity to genes outside of these lineages and have, therefore, alternatively been named taxonomically restricted genes. They were so far considered to emerge through duplication–divergence processes,but it isnow becomingclear that they canalso arise de novo out of noncoding deoxyribonucleic acid (DNA). This latter proc...
متن کاملAn evolutionary expressed sequence tag analysis of Drosophila spermatheca genes.
This study investigates genes enriched for expression in the spermatheca, the long-term sperm storage organ (SSO) of female Drosophila. SSO genes are likely to play an important role in processes of sexual selection such as sperm competition and cryptic female choice. Although there is keen interest in the mechanisms of sexual selection at the molecular level, very little is known about the fem...
متن کاملThe life cycle of Drosophila orphan genes
Orphans are genes restricted to a single phylogenetic lineage and emerge at high rates. While this predicts an accumulation of genes, the gene number has remained remarkably constant through evolution. This paradox has not yet been resolved. Because orphan genes have been mainly analyzed over long evolutionary time scales, orphan loss has remained unexplored. Here we study the patterns of orpha...
متن کاملanalysis of power in the network society
اندیشمندان و صاحب نظران علوم اجتماعی بر این باورند که مرحله تازه ای در تاریخ جوامع بشری اغاز شده است. ویژگیهای این جامعه نو را می توان پدیده هایی از جمله اقتصاد اطلاعاتی جهانی ، هندسه متغیر شبکه ای، فرهنگ مجاز واقعی ، توسعه حیرت انگیز فناوری های دیجیتال، خدمات پیوسته و نیز فشردگی زمان و مکان برشمرد. از سوی دیگر قدرت به عنوان موضوع اصلی علم سیاست جایگاه مهمی در روابط انسانی دارد، قدرت و بازتولید...
