Protocol for an agent-based model of recombination in bacteria playing a public goods game

STAR Protocols, 2023
Summary: Agent-based models are composed of individual agents coded for traits, such as cooperation and cheating, that interact in a virtual world based on defined rules.

Evolutionary activation of acidic chitinase in herbivores through the H128R mutation in ruminant livestock

iScience, 2023
Summary: Placental mammals' ancestors were insectivores, suggesting that modern mammals may have inherited the ability to digest insects. Acidic chitinase (Chia) is a crucial enzyme hydrolyzing significant component of insects' exoskeleton in many ...

Long-term culturing of Pseudomonas aeruginosa in static, minimal nutrient medium results in increased pyocyanin production, reduced biofilm production, and loss of motility

Applied and Environmental Microbiology
Pseudomonas aeruginosa is a multidrug-resistant opportunistic human pathogen that can survive in many natural and anthropogenic environments. It is a leading cause of morbidity in individuals with cystic fibrosis and is one of the most prevalent ...

Transcriptional effects of a positive feedback circuit in Drosophila melanogaster

BMC Genomics, 2017
Background Synthetic systems that use positive feedback have been developed to control human disease vectors and crop pests. The tTAV system, which has been deployed in several insect species, relies on a positive feedback circuit that can be inhibited ...

Developmental biology, the stem cell of biological disciplines. [PDF]

PLoS Biology, 2017
Developmental biology (including embryology) is proposed as "the stem cell of biological disciplines." Genetics, cell biology, oncology, immunology, evolutionary mechanisms, neurobiology, and systems biology each has its ancestry in developmental biology.

Genome structure and evolutionary history of frankincense producing Boswellia sacra

iScience, 2022
Summary: Boswellia sacra Flueck (family Burseraceae) tree is wounded to produce frankincense. We report its de novo assembled genome (667.8 Mb) comprising 18,564 high-confidence protein-encoding genes.

Speciation Through the Lens of Population Dynamics: A Theoretical Primer on How Small and Large Populations Diverge

Population Ecology, EarlyView.
Population size and dynamics fundamentally shape speciation by influencing genetic drift, founder events, and adaptive potential. Small populations may speciate rapidly due to stronger drift, whereas large populations harbor more genetic diversity, which can alter divergence trajectories. We highlight theoretical models that incorporate population size

Early genome erosion and internal phage-symbiont-host interaction in the endosymbionts of a cold-seep tubeworm

iScience, 2023
Summary: Endosymbiosis with chemosynthetic Gammaproteobacteria is widely recognized as an adaptive mechanism of siboglinid tubeworms, yet evolution of these endosymbionts and their driving forces remain elusive.

Mechanisms and kinetic assays of aminoacyl‐tRNA synthetases

FEBS Letters, EarlyView.
Accurate protein synthesis is crucial for life. The key players are aminoacyl‐tRNA synthetases (AARSs), which read the genetic code by pairing cognate amino acids and tRNAs. AARSs establish high amino acid selectivity by employing physicochemical limits in molecular recognition.

Plastic cell morphology changes during dispersal

iScience, 2021
Summary: Dispersal is the movement of organisms from one habitat to another that potentially results in gene flow. It is often plastic, allowing organisms to adjust dispersal movements depending on environmental conditions.
