Chromosome-level genome assembly and annotation of the Amur rat snake Elaphe schrenckii
Zexian Zhu and others
The Amur rat snake ( Elaphe schrenckii ), a widely distributed colubrid species in Northeast Asia, plays a critical role in controlling rodent and mouse populations in the wild. Despite its ecological and evolutionary significance, genomic resources for this non-venomous species have been limited. ...
Genomics of experimental adaptive radiation in the cryptic coloration of feather lice
James G Baldwin-Brown and others
A major challenge faced by living organisms is adaptation to novel environments. This process is poorly understood because monitoring genetic changes in natural populations is difficult. One way to simplify the task is to focus on organisms that can be studied in captivity under conditions that ...
Selection for early reproduction leads to accelerated aging and extensive metabolic remodeling in Drosophila melanogaster
David L Hubert and others
Experimental evolution studies that feature selection on life-history characters are a proven approach for studying the evolution of aging and variation in rates of senescence. Recently, the incorporation of genomic and transcriptomic approaches into this framework has led to the identification of ...
The Precision and Power of Population Branch Statistics in Identifying the Genomic Signatures of Local Adaptation
Max Shpak and others
Population branch statistics, which estimate the degree of genetic differentiation along a focal population’s lineage, have been used as an alternative to F ST -based genome-wide scans for identifying loci associated with local selective sweeps. Beyond the population branch statistic (PBS), the ...
Genome-wide demographic analyses of balaenid whales revealed complex history of gene flow associated with past climate oscillation
Bai-Wei Lo and others
The balaenid whale, comprising three species of right whales and the bowhead whale, represents an ancient and highly endangered lineage of marine mammals. To unravel the evolutionary history of balaenid whales with respect to gene flow, a comprehensive analysis based on whole-genome data was ...
Genome evolution of two intertidal Sargassum species (S. fusiforme and S. thunbergii) and their response to abiotic stressors
Hocheol Kim and others
Sargassum fusiforme and Sargassum thunbergii are ecologically and commercially important seaweeds that thrive in intertidal zones and are frequently exposed to extreme variation in environmental stress. Despite their importance, limited genomic information exists for these species, which hinders a ...
Evolution of Pineal Nonvisual Opsins in Lizards and the Tuatara and Identification of Lepidopsin: A New Opsin Gene
Ricardo D Romero and Flávio S J de Souza
Many lizards (Squamata), as well as the tuatara (Rhynchocephalia), are distinguished among vertebrate groups for the presence of the parietal eye, or “third eye”, a structure derived from the pineal complex containing a simplified retina with photoreceptor cells. The parietal eye expresses ...
Exploring Mobile Genetic Elements in Vibrio cholerae
Natália C Drebes Dörr and others
Members of the bacterial species Vibrio cholerae are known both as prominent constituents of marine environments and as the causative agents of cholera, a severe diarrheal disease. While strains responsible for cholera have been extensively studied over the past century, less is known about their ...
