Another potential source of lineage-specific genes is gene duplication followed by rapid evolution.
The placenta is a rich source of lineage-specific genes that function in the adaptive evolution of placental architecture and functions.
Gene duplication followed by rapid sequence divergence in one of the paralogs is a well explored source of lineage-specific genes [ 75, 91].
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.
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].
Although more data are needed to better understand these associations, the most parsimonious explanation is that a hantavirus associated with Necromys spp./ Akodon spp. that originated in the southern region may have been the source of the lineage that led to Oligoryzomys spp. associated JUQV, which has lineages across the Araucária pine forests and along the rain forests into southeastern Brazil.
But it is interesting that he views the 500-year-old origin of lineage and his 'middle temperament' to come from the same source.
Such estimates have very broad 95% confidence intervals and, thus, cannot be used to precisely pinpoint the original source of these lineages.
TEs, such as Madel, represent a natural source of such lineage-specific miRNAs, which could in turn be responsible for regulatory phenotypes that contribute to evolutionary diversification between species.
Our overall results demonstrate the huge phenotypic and phylogenetic diversity of haloalkaliphiles in saline systems of southern Tunisia which represent a valuable source of new lineages and metabolites.
The detected phenotypic and phylogenetic diversity points out that saline systems of southern Tunisia could represent a valuable source of new lineages and metabolites.
