Mitochondrial genomes of Columbicola feather lice are highly fragmented, indicating repeated evolution of minicircle-type genomes in parasitic lice [PDF]
PeerJ, 2020 Most animals have a conserved mitochondrial genome structure composed of a single chromosome. However, some organisms have their mitochondrial genes separated on several smaller circular or linear chromosomes.

Proceedings of the National Academy of Sciences of the United States of America, 2020 Significance The biosynthetic genes of some specialized plant metabolites appear to be clustered in the genomes of higher plants. Momilactones are defense compounds produced in rice and barnyard grass by family-conserved biosynthetic gene clusters (BGCs).

Frontiers in Ecology and Evolution, 2022 Experimental evolution is an approach that allows researchers to study organisms as they evolve in controlled environments. Despite the growing popularity of this approach, there are conceptual gaps among projects that use different experimental designs.

Convergent Evolution of Boats with Sails [PDF]
Scientific Reports, 2020 AbstractThis article unveils the geometric characteristics of boats with sails of many sizes, covering the range 102–105 kg. Data from one hundred boat models are collected and tabulated. The data show distinct trends of convergent evolution across the entire range of sizes, namely: (i) the proportionality between beam and draft, (ii) the ...

Frontiers in Plant Science, 2013 Early plants began colonizing the terrestrial earth approximately 450 million years ago. Their success on land has been partially attributed to the evolution of specialized metabolic systems from core metabolic pathways, the former yielding structurally ...

BMC Genomics, 2020 Background To date, evidence for the relative prevalence or rarity of molecular convergent and parallel evolution is conflicting, and understanding of how these processes contribute to adaptation is limited. We compared four high-elevation anuran species

Convergent evolution of processivity in bacterial and fungal cellulases
Proceedings of the National Academy of Sciences of the United States of America, 2020 Significance Some cellulases exhibit “processivity”: the ability to degrade crystalline cellulose through successive hydrolytic catalytic reactions without the release of the enzyme from the substrate surface.

FEBS Letters, EarlyView.We identified a systemic, progressive loss of protein S‐glutathionylation—detected by nonreducing western blotting—alongside dysregulation of glutathione‐cycle enzymes in both neuronal and peripheral tissues of Taiwanese SMA mice. These alterations were partially rescued by SMN antisense oligonucleotide therapy, revealing persistent redox imbalance as ...
