Evolution of trace amine associated receptor (TAAR) gene family in vertebrates: lineage-specific expansions and degradations of a second class of vertebrate chemosensory receptors expressed in the
TLDR
expression analysis of zebrafish and stickleback TAAR genes revealed that many TAARs in these fishes were expressed in the olfactory organ, suggesting the relatively high importance ofTAARs as chemosensory receptors in fishes. Expand
Evolution and origin of vomeronasal-type odorant receptor gene repertoire in fishes
TLDR
The results have indicated that the evolutionary dynamics of fish V2Rs are characterized by rapid gene turnover and lineage-specific phylogenetic clustering, and have expanded after the divergence between teleost and tetrapod lineages. Expand
A Ycf2-FtsHi Heteromeric AAA-ATPase Complex Is Required for Chloroplast Protein Import[OPEN]
TLDR
It is reported that a 2-MD heteromeric AAA-ATPase complex associates with the TIC complex and functions as the import motor, directly interacting with various translocating preproteins, advancing the understanding of this ATP-driven protein translocation system that is unique to the green lineage of photosynthetic eukaryotes. Expand
Temporal pattern of loss/persistence of duplicate genes involved in signal transduction and metabolic pathways after teleost-specific genome duplication
TLDR
It is proposed that more than ten thousand of 3R-WGD-derived duplicates have experienced lineage-specific evolution, that is, the differential sub-/neo-functionalization or secondary loss between lineages, and contributed to teleost diversity. Expand
Arabidopsis Molybdopterin Biosynthesis Protein Cnx5 Collaborates with the Ubiquitin-like Protein Urm11 in the Thio-modification of tRNA*
TLDR
It is demonstrated here that Arabidopsis sulfurtransferase Cnx5, a ubiquitin-activating enzyme-like (UBA) protein involved in molybdopterin (MPT) biosynthesis, is strictly required for the thio-modification of cytosolic tRNAs in vivo. Expand
Gene rearrangements in gekkonid mitochondrial genomes with shuffling, loss, and reassignment of tRNA genes
TLDR
Seven new mitogenomic sequences from Gekkonidae are determined using a high-throughput sequencing method and raise new questions as to how missing tRNAs are supplied and if the reassigned tRNA gene is fully functional. Expand
Evolutionary Patterns and Selective Pressures of Odorant/Pheromone Receptor Gene Families in Teleost Fishes
TLDR
Frequent gene gains/losses and high KA/KS in teleost TAARs suggest that receptors in this family are used for detecting some species-specific chemicals such as pheromones, Conversely, conserved repertoires of V1R and V2R families inteleost fishes may imply that receptor in these families perceive common odorants for teleosts, such as amino acids. Expand
Characterization and evolutionary analysis of tributyltin‐binding protein and pufferfish saxitoxin and tetrodotoxin‐binding protein genes in toxic and nontoxic pufferfishes
TLDR
The evolutionary dynamics of TBT‐bp2 and PSTBP genes are examined to understand the evolution of toxin accumulation in pufferfishes and it is suggested that PSTBPs evolved in the common ancestor of Takifugu species by repeated duplications and fusions of T BT‐BP2 genes. Expand
Evolution of vomeronasal-type odorant receptor genes in the zebrafish genome.
TLDR
The evolution of the zebrafish V2R gene family can be explained by repeated tandem gene duplications within gene clusters and large-scale duplications among chromosomes. Expand
Characterization of Squamate Olfactory Receptor Genes and Their Transcripts by the High-Throughput Sequencing Approach
TLDR
The high-throughput next-generation sequencing (NGS) approach was applied to characterization of OR gene repertoires in the green anole lizard Anolis carolinensis and the Japanese four-lined ratsnake Elaphe quadrivirgata, implying that the snake has more OR gene loci than the anoles in response to an increased need for the acuity of olfaction.
