#genomes — Public Fediverse posts

Some #snakes lack the ‘#hunger #hormone.’ Experts are hungry to know why
The #gene for #ghrelin is missing in serpents, yet present in other fasting #reptiles
Evolutionary #geneticist Rui Pinto and colleagues stumbled on the discovery when comparing the #genomes of 112 reptile species, including snakes, crocodiles and chameleons, which they obtained from public database. Genes for ghrelin and its activating enzyme were absent in 32 snake species.

Tiny #Worms Living Near #Chernobyl Have Evolved a Remarkable New Talent
#Nematodes collected from the area have shown no sign of damage to their #genomes, contrary to what might be expected for organisms living in such a dangerous place. The finding doesn't suggest the #CEZ is safe, the researchers say, but rather the worms are resilient and able to adroitly adapt to conditions that might be inhospitable to other species.

#Genomic analysis sheds light on how #seagrasses conquered the sea

#Seagrass #genomes reveal ancient #polyploidy and adaptations to the marine environment https://www.nature.com/articles/s41477-023-01608-5

"Seagrasses evolved from their #freshwater ancestors only 3x. To do this required specialized ecological tolerance to high #salinity, lower light, a wide range of temperature tolerances, #underwater carbon capture, different #pathogen defense, structural flexibility and underwater #pollination"

#Scaphopoda is the sister taxon to #Bivalvia: Evidence of ancient incomplete lineage sorting https://www.pnas.org/doi/10.1073/pnas.2302361120

"#Scaphopods exhibit a mosaic of features resembling other lineages: tentacles like the arms of #cephalopods, unique shell ontology similar to #bivalves, and a partially degenerated head that seemingly represents an intermediate state between bivalves and #gastropods"

#Parasitic plant convinces hosts to grow into its own flesh—it's also an extreme example of genome shrinkage https://phys.org/news/2023-09-parasitic-convinces-hosts-fleshit-extreme.html

#Balanophora #genomes display massively #ConvergentEvolution with other extreme #holoparasites and provide novel insights into parasite–host interactions https://www.nature.com/articles/s41477-023-01517-7

"unlike some other #ParasiticPlants, Balanophora induces the vascular system of their host plant to grow into a tuber, forming a unique underground organ with mixed host-parasite tissue."
