From mice to humans—divergent strategies for intestinal homeostasis and regeneration

open access: yesFEBS Letters, EarlyView.
Recent advances such as organoid genome editing, xenotransplantation, imaging, and whole‐genome sequencing have enabled direct studies of human intestinal stem cells (ISCs). These studies reveal species‐specific features, including slower ISC proliferation, distinct injury responses, slower somatic mutation accumulation in humans, and an inverse ...

Evolutionary sparse learning reveals the shared genetic basis of convergent traits

open access: yesNature Communications
Cases abound in which nearly identical traits have appeared in distant species facing similar environments. These unmistakable examples of adaptive evolution offer opportunities to gain insight into their genetic origins and mechanisms through ...

Shining fresh light on the evolution of photosynthesis

open access: yeseLife, 2013
There are two types of photosynthesis, C3 and C4, and computational techniques have been used to explore how C4 plants evolved from their C3 ancestors.

Genome encode analyses reveal the basis of convergent evolution of fleshy fruit ripening

open access: yesNature Plants, 2018
Fleshy fruits using ethylene to regulate ripening have developed multiple times in the history of angiosperms, presenting a clear case of convergent evolution whose molecular basis remains largely unknown.

Structural insights and therapeutic targets in Acinetobacter baumannii capsule biosynthesis

open access: yesFEBS Letters, EarlyView.
Hypervirulent KL49 A. baumannii's capsular polysaccharide contains the nonulosonic acid 8‐epi‐Leg5,7Ac2, synthesized by epimerization via ElaA, ElaB, and ElaC. Crystal structures of ElaA, ElaB, and ElaC reveal their role in CMP‐Leg5,7Ac2 synthesis and regioselective C8 epimerization.

Variable gene transcription underlies phenotypic convergence of hypoxia tolerance in sculpins

open access: yesBMC Evolutionary Biology, 2018
Background The degree by which mechanisms underlying phenotypic convergence are similar among taxa depends on the number of evolutionary paths available for selection to act upon.

Convergent Evolution of Vocal Cooperation without Convergent Evolution of Brain Size

open access: yesBrain, Behavior and Evolution, 2014
One pragmatic underlying successful vocal communication is the ability to take turns. Taking turns - a form of cooperation - facilitates the transmission of signals by reducing the amount of their overlap. This allows vocalizations to be better heard. Until recently, non-human primates were not thought of as particularly cooperative, especially in the ...

Three phosphatase families form a community: The phosphohydrolases that act upon inositol pyrophosphates

open access: yesFEBS Letters, EarlyView.
Inositol pyrophosphates are energy‐rich signaling molecules that perform critical functions in cells. Three different families of phosphatases hydrolyze the β phosphate of the inositol pyrophosphate molecules: two have narrow specificities and one is promiscuous.

Convergent Evolution of Slick Coat in Cattle through Truncation Mutations in the Prolactin Receptor

open access: yesFrontiers in Genetics, 2018
Evolutionary adaptations are occasionally convergent solutions to the same problem. A mutation contributing to a heat tolerance adaptation in Senepol cattle, a New World breed of mostly European descent, results in the distinct phenotype known as slick ...

A Similar Genetic Architecture Underlies the Convergent Evolution of the Selfing Syndrome in Capsella

open access: yesThe Plant Cell, 2020
Independent evolutionary reductions of petal size in the genus Capsella are associated with convergent evolution of gene expression and underlain by similar genetic architectures.
