From junk to function — How weak selection in eukaryotes builds new parts and drives genomic complexity

open access: yesFEBS Letters, EarlyView.
How do genomes gain new functional parts? In eukaryotes, which tend to evolve under weak selection, much of the genome is junk. Palazzo and Qiu borrow the logic of Markov chains to show how non‐functional DNA becomes functional through the appearance of intermediate states, which arise due to epistasis, buffering, and biochemical messiness, allowing ...

The complete mitochondrial genome of the Parasa tessellata (Lepidoptera: Limacodidae)

open access: yesMitochondrial DNA. Part B. Resources, 2019
In the present study, the complete sequence of the mitochondrial genome (mitogenome) of Parasa tessellata (Lepidoptera: Limacodidae) is described. The mitogenome (15,308 bp) of P.

Gaps as Characters in Sequence-Based Phylogenetic Analyses [PDF]

open access: yesSystematic Biology, 2000
In the analysis of sequence-based data matrices, the use of different methods of treating gaps has been demonstrated to in? fluence the resulting phylogenetic hypothe? ses (e.g., Eernisse and Kluge, 1993; Vogler and DeSalle, 1994; Simons and Mayden, 1997). Despite this influence, a well-justi?

The heterodimeric amino acid transporters (HAT) of the SLC7/SLC3 family: A structure−function relationships and relevance to human pathology

open access: yesFEBS Letters, EarlyView.
Heterodimeric amino acid transporters consist of SLC7 and SLC3 family proteins arranged in a conserved structural organization. They regulate nutrient transport across cell membranes, supporting essential cellular functions. These transporters also contribute to xenobiotic/drug uptake and distribution.

The complete mitochondrial genome of the Gongxi chicken and its phylogenetic analyses

open access: yesMitochondrial DNA. Part B. Resources, 2019
Gongxi chicken (GXC) is one of the famous indigenous breed of Hunan province in China. It is the first time that the complete mitochondrial genome sequence of the GX was reported. The total length of the mtDNA is 16,783 bp.

Phylogenetic analyses of Chaetopteridae (Annelida)

open access: yesZoologica Scripta, 2017
Phylogenetic relationships within Chaetopteridae were assessed using parsimony cladistic analysis of 43 external morphological characters and molecular phylogenetic analysis of three genes: mitochondrial cytochrome oxidase subunit I DNA (COI) and nuclear 28S and 18S ribosomal DNA. The group currently comprises four accepted genera: Chaetopterus Cuvier,

Intrapatient tumour heterogeneity and clonal evolution in an autopsy study of metastatic salivary gland cancer

open access: yesMolecular Oncology, EarlyView.
Tumour heterogeneity and clonal evolution of metastatic salivary gland cancer were evaluated in two patients with adenoid carcinoma and one patient with myoepithelial carcinoma. Radiology‐guided autopsy enabled multi‐region sampling (total samples n = 149), followed by whole‐genome sequencing and phylogenetic reconstruction (17 tumour samples, 4–7 per ...
