Summary: The biosynthetic pathways of domoic acid differ between diatoms and red macroalgae, with the absence of a critical enzyme in red macroalgae. Red macroalgae produce domoic acid via isodomoic acid B, with a unique origin of the rad genes compared to diatoms. The production of domoic acid in diatoms and red macroalgae involves a combination of native eukaryotic CYP450 neofunctionalization and horizontal gene transfer.

Summary: This study used comparative genomics to investigate the genetic variation and adaptation potential of 20 krill species collected from different oceans. The results showed that Antarctic krill species had lower levels of genetic variation and evolutionary rates, indicating a potentially lower adaptive potential to rapid climate change. Additionally, the study identified several candidate genes associated with adaptive evolution in Antarctic krill.

Summary: Type I and type II keratins are subgroups of intermediate filament proteins that provide toughness to the epidermis and protect it from water loss. Ancient fish lineages share keratin gene clusters, with a novel subcluster found in reedfish. Molecular evolutionary analyses suggest that amphibians' epidermal keratin gene subclusters originated from non-terrestrial ancestors.

Summary: This study compares and analyzes the chromosome-scale reference genome of the natural allotetraploid grass Brachypodium hybridum, revealing gradual gene loss and chromosome rearrangement during genome integration. However, no signs of homeologous recombination or pronounced transposable element activation were found, indicating a relatively mild genome dominance.

Summary: Gene loss is a common source of genetic variation in genome evolution. We developed a new pipeline that integrates orthologous inference and genome alignment to effectively identify loss events. We discovered 33 gene loss events that give rise to novel lncRNAs with distinct expression features and potential functions related to growth, development, immunity, and reproduction in humans. Our data also revealed variable rates of protein gene loss and functional biases among different lineages.

Summary: Members of the DUF34 family, also known as the NIF3 protein superfamily, have been widely annotated as GTP cyclohydrolase I type 2, but new research suggests they may serve as metal ion insertases, chaperones, or metallocofactor maturases. This diverse molecular function could explain their involvement in pathways such as cell differentiation, metal ion homeostasis, pathogen virulence, redox, and universal stress responses.

Summary: By sequencing the genome of C. hongkongensis and comparing it to other reference bivalve genomes, this study identified the genomic determinants driving the shift from byssal to cemented attachment in oysters. The loss of the Antennapedia gene and expansion of lineage-specific extracellular gene families were found to be implicated in this transition. Transcriptomic analysis revealed significant differences in gene expression profiles between the asymmetrical C. hongkongensis and the symmetrical P. fucata, including elevated expression of orthologous transcription factor genes and lineage-specific shell-related gene families.

Summary: Dromedaries, important livestock, can act as a vector for transmitting zoonotic viruses such as MERS-CoV and CCHFV to humans. A recent study in the UAE found that CCHFV is endemic in dromedaries and camel ticks. The study identified two candidate immune genes, FCAR and CLEC2B, which play important roles in host defense against viral infections.

Summary: In South Africa, the cheetah population is divided into free-roamers, managed metapopulation, and captive facilities. To preserve overall genetic variation, interventions such as genetic exchanges and supplementation with unrelated individuals are proposed. Simulation results showed that without intervention or with only genetic exchanges, there were significant losses of heterozygosity and an increase in the frequencies of close relatives. However, introducing individuals from captive facilities maintained genetic diversity and relatedness.

Summary: The study focuses on the localization of transglutaminase activity in various integumentary structures in mammals and birds. Transglutaminase activity was found in different layers of human epidermis, sweat glands, hair follicles, and nails. It was also present in claws, feathers, and keratinocytes of feathers in chickens. Additionally, transglutaminase activity was detected in tongue papillae of mice and chickens. The study suggests that transglutamination contributes to the cornification of hard skin appendages.

Summary: Until recently, dromedaries were used for various purposes such as transportation and production of meat, milk, and wool. However, the production of dromedary milk has steadily increased in recent decades due to its perceived health benefits. This has led to changes in animal welfare, gene composition, and the need for improved regulation and legislation to ensure food safety and well-being of dromedaries.

Summary: This study explores the morphological differences between different goat populations in Burkina Faso using morphometric traits. The results show that there is no strict distinction between the two populations, indicating a close genetic relationship. Four groups were identified based on body size, representing the main breeds and their crosses. These different goat morphotypes are the result of farmers breeding practices. The study highlights the need for sustainable genetic improvement approaches for the use of these adapted local goat genetic resources.

Summary: This study identified inactivating mutations of OAS genes in primates through comparative genomics and revealed a diversifying evolution pattern of the OAS gene family. The study also found that camelids lack OAS2 and OAS3 genes, Asian pangolins lack both OASL and OAS3 genes, and a new OAS gene (OAS5) is present in the bat suborder Yangochiroptera. These differences may affect innate immune responses to coronaviruses and other RNA viruses.
