More recently, it has been suggested that the pool of transposable elements can be domesticated to serve as a 'warehouse' for natural selection, potentially acting as a source of lineage-specific elements [ 47, 48].
One caveat is that inside the rostral diencephalon there is a source of Foxb1-lineage cells, the mammillary area, which contributes cells to more rostral regions (caudorostral intrahypothalamic migration).
Carrying conjugative cluster genes, as well as new variants of etb and edinA genes, pETB608 could be regarded as a source of a new lineage of ETB plasmids.
This limited number, which includes matches to other plant species, suggests that lateral gene transfer is a not a major source of lineage-specific genes in A. thaliana.
The placenta is a rich source of lineage-specific genes that function in the adaptive evolution of placental architecture and functions.
However, the current taxonomy of the group remains a source of debate, with distinct lineages indicated either as one species or distinct species or subspecies (e.g., [27], [28], [29], [30]).
He underlined the fact that synovial sarcoma mouse models expressing the chimeric SYT SSX2 fusion protein were useful to identify the skeletal muscle lineage as a source of synovial sarcoma.
Gene duplication followed by rapid sequence divergence in one of the paralogs is a well explored source of lineage-specific genes [ 75, 91].
While the CD22+TWEAK+ expressing B cells may be a specific population associated with the chronic inflammation seen in RA, CD22-positive B lymphocytes isolated from human normal peripheral blood also expressed abundant levels of TWEAK mRNA, suggesting that B-lineage cells are a source of TWEAK.
The lineage of struggle as a source of solidarity can be traced back to the work of Karl Marx and Max Weber (Stjerno, 2004).
The programme could help determine Tutankhamun's family lineage, which has long been a source of mystery.
