Cross-species gene transfer: a major factor in evolution?
1 Recently I presented a very speculative theory which suggests that the transfer of genes from one species to another may play a significant role in evolution. Although this theory remains as speculative as the day I wrote it, a number of unexpected experimental results have just been published which were either predicted by the theory or are pertinent to it. Here I briefly summarize the centr...
متن کاملGene transfer is a major factor in bacterial evolution.
Lateral gene transfer in four strains of Salmonella enterica has been assessed using genomic subtraction. Strain LT2 (subspecies I serovar Typhimurium) chromosomal DNA was used as target and subtracted by three subspecies I strains of serovars Typhimurium (S21), Muenchen (S71), Typhi (M229), and a subspecies V strain (M321). Data from probing random cosmids of LT2 DNA with preparations of the r...
متن کاملCross-species gene transfer; implications for a new theory of evolution.
It has been established that genes can be transferred and expressed among procaryotes of different species. I am hypothesizing--and there is mounting evidence for this conclusion--that genes are transferred and expressed among all species, and that such exchange is facilitated by, and can help account for, the existence of the biological unities, from the uniform genetic code to the cross-speci...

چکیده حیطه ی نوشتار دانشگاهی اخیرا شاهد تغییرات عمده ای از غیرشخصی بودن (عینی بودن) به شخصی بودن بوده است. شخصی بودن متون دانشگاهی اهمیت استفاده از وجهیت معرفتی را برجسته می سازد چرا که? وجهیت معرفتی? بر اساس یکی از تعاریف ارائه شده از این مقوله? ارتباط تنگاتنگی با شخصی بودن داشته و به عنوان بیان نظر شخصی گوینده در مورد جز گزاره ای گفته در نظر گرفته میشود. بنابراین? با در نظر داشتن نقاط مشترک...
15 صفحه اولHorizontal Gene Transfer in Evolution
The concept of horizontal or lateral gene transfer (the non-genealogical transmission of genetic material between organisms) was introduced in 1990s to explain the observed incongruence in phylogenetic reconstructions using different genes. Today, horizontal gene transfer is accepted as an important force modulating evolution of Bacteria, Archaea and unicellular eukaryotes, and evidence is risi...
