TLR7 neo-functionalizes to sense dsRNA and trigger antiviral and antibacterial immunity in non-tetrapod vertebrates

open access: yesiScience, 2023
Summary: TLR7 plays a crucial role in sensing viral ssRNA and initiating immune responses. Piscine TLR7 also responds to dsRNA challenge. dsRNA exists in almost all the viruses at specific stages.

Plastic cell morphology changes during dispersal

open access: yesiScience, 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.

Alternative telomere maintenance mechanism in Alligator sinensis provides insights into aging evolution

open access: yesiScience, 2023
Summary: Lifespan is a life-history trait that undergoes natural selection. Telomeres are hallmarks of aging, and shortening rate predicts species lifespan, making telomere maintenance mechanisms throughout different lifespans a worthy topic for study ...

The evolutionary advantage of diploid sex [PDF]

open access: yesarXiv, 2002
We modify the Penna Model for biological aging, which is based on the mutation-accumulation theory, in order to verify if there would be any evolutionary advantage of triploid over diploid organisms. We show that this is not the case, and that usual sex is always better than that involving three individuals.

Group size influences maternal provisioning and compensatory larval growth in honeybees

open access: yesiScience, 2023
Summary: Environmental variation selects for the adaptive plasticity of maternal provisioning. Even though developing honeybees find themselves in a protected colony environment, their reproductively specialized queens actively adjust their maternal ...

Evolutionary Biology Needs Wild Microbiomes

open access: yesFrontiers in Microbiology, 2017
The microbiome is a vital component to the evolution of a host and much of what we know about the microbiome derives from studies on humans and captive animals.

The PWWP domain and the evolution of unique DNA methylation toolkits in Hymenoptera

open access: yesiScience, 2023
Summary: DNMT3 in Hymenoptera has a unique duplication of the essential PWWP domain. Using GST-tagged PWWP fusion proteins and histone arrays we show that these domains have gained new properties and represent the first case of PWWP domains binding to ...
