Leaf beetles' evolutionary success linked to gene transfer and symbiosis phys.org/news/2025-01-leaf-bee

"Almost all #LeafBeetles have incorporated foreign genetic material into their genome, which is responsible for the production of #enzymes necessary to digest plant cell wall components... half of the species of leaf #beetles live in close association with symbiotic #bacteria. These #symbionts provide the beetles with important digestive enzymes, vitamins, and amino acids."

J'en parlais avec un ami pour expliquer la nature du #vivant... drôle de mélange de #chimie de #mecanique de #nanotechnologie naturelle, d'essai erreur, de code, etc...

Les nanotechnologies du vivant ridiculisent celles créées par l'humain.

Ici on voit une turbine avec rotor extérieur stator intérieur une tige antirotation et les #enzymes transformant énergie mécanique en énergie chimique...

Spanish mother and daughter train #bacteria to restore church frescoes reuters.com/science/spanish-mo #microbes

"As Spanish #microbiologist Pilar Bosch was casting around for a subject to investigate for her PhD, she stumbled across a paper suggesting that bacteria, her field, could be used in #ArtRestoration, her mother's own area of expertise... The microbiologist trains bacteria by feeding them samples of glue. The bacteria then naturally produce #enzymes to degrade the glue."

First report of microbial #symbionts in the digestive system of #shipworms; wood boring mollusks sciencedirect.com/science/arti

"a population of symbiotic #microbes, living in an overlooked sub-organ of the gut called the #typhlosole, have the ability to secrete the #enzymes needed to digest #lignin—the toughest part of wood."

"We find that #purine synthesis constitutes a bottleneck for metabolic expansion, which can be alleviated by non-autocatalytic phosphoryl coupling agents. Early phases of the expansion are enriched with #enzymes that are metal dependent and structurally symmetric, supporting models of early #biochemical #evolution. This expansion trajectory suggests distinct hypotheses regarding the tempo, mode and timing of metabolic pathway evolution"

NaturePrimitive purine biosynthesis connects ancient geochemistry to modern metabolism - Nature Ecology & EvolutionConstructing a biosphere-scale model of the evolutionary history of metabolism based on >12,000 biochemical reactions, the authors show that a bottleneck in purine synthesis prevents metabolic expansion from geochemical precursors.
