Dynamic Evolution of Avian RNA Virus Sensors: Repeated Loss of RIG-I and RIPLET

open access: yesViruses, 2022
Retinoic acid-inducible gene I (RIG-I) and melanoma differentiation-associated protein 5 (MDA5) are key RNA virus sensors belonging to the RIG-I-like receptor (RLR) family.

The Vertebrate TLR Supergene Family Evolved Dynamically by Gene Gain/Loss and Positive Selection Revealing a Host–Pathogen Arms Race in Birds

open access: yesDiversity, 2019
The vertebrate toll-like receptor (TLRs) supergene family is a first-line immune defense against viral and non-viral pathogens. Here, comparative evolutionary-genomics of 79 vertebrate species (8 mammals, 48 birds, 11 reptiles, 1 amphibian, and 11 fishes)

The Expansion of Animal MicroRNA Families Revisited

open access: yesLife, 2015
MicroRNAs are important regulatory small RNAs in many eukaryotes. Due to their small size and simple structure, they are readily innovated de novo. Throughout the evolution of animals, the emergence of novel microRNA families traces key morphological ...

Plastome phylogeny and lineage diversification of Salicaceae with focus on poplars and willows

open access: yesEcology and Evolution, 2018
Phylogenetic relationships and lineage diversification of the family Salicaceae sensu lato (s.l.) remain poorly understood. In this study, we examined phylogenetic relationships between 42 species from six genera based on the complete plastomes ...

The complete chloroplast genome of a hemiparasitic plant Tolypanthus maclurei (Loranthaceae)

open access: yesMitochondrial DNA. Part B. Resources, 2019
Parasitic plants often show changes in chloroplast genome size and gene content. Here we obtained the complete chloroplast genome of Tolypanthus maclurei, a hemiparasitic shrub of Loranthaceae, using genome skimming method. It is 123,581 bp in length and

Extensive gene loss in the plastome of holoparasitic plant Cistanche tubulosa (Orobanchaceae)

open access: yesMitochondrial DNA. Part B. Resources, 2020
Extensive photosynthetic gene loss and rapid evolutionary rate occur in the plastomes of parasitic plants. The holoparasitic plant Cistanche tubulosa of Orobanchaceae is an important medicinal resources that are distributed in arid areas.

Comparative Chloroplast Genomics of Sophora Species: Evolution and Phylogenetic Relationships in the Early-Diverging Legume Subfamily Papilionoideae (Fabaceae)

open access: yesFrontiers in Plant Science, 2021
The taxonomy and evolutionary history of Sophora L., a genus with high economic and medicinal value, remain uncertain due to the absence of genetic resource (especially in China) and low polymorphism of molecular markers.

The complete chloroplast genome sequence of Taxillus yadoriki (Loranthaceae): a hemi-parasitic evergreen shrub in East Asia

open access: yesMitochondrial DNA. Part B. Resources, 2020
Taxillus yadoriki (Loranthaceae) is a hemiparasitic evergreen shrub distributed in Korea and Japan. We report the complete chloroplast genome of T. yadoriki to provide insight into the phylogenetic relationship of Loranthaceae.
