Moraga C, Branco C, Rougemont Q, Jedlicka P, Mendoza-Galindo E, Veltsos P, et al.
Science
. 2025 Feb;
387(6734):630-636.
PMID: 39913565
In many species with sex chromosomes, the Y is a tiny chromosome. However, the dioecious plant has a giant ~550-megabase Y chromosome, which has remained unsequenced so far. We used...

Genome Biol Evol
. 2024 Oct;
16(10).
PMID: 39391977
Genomic regions that play a role in parasite defense are often found to be highly variable, with the major histocompatibility complex serving as an iconic example. Single nucleotide polymorphisms may...

Santos J, Nick F, Adhitama N, Fields P, Stillman J, Kato Y, et al.
Curr Biol
. 2024 Aug;
34(18):4160-4169.e7.
PMID: 39168123
Salinization poses an increasing problem worldwide, threatening freshwater organisms and raising questions about their ability to adapt. We explored the mechanisms enabling a planktonic crustacean to tolerate elevated salinity. By...

Mol Biol Evol
. 2024 Jun;
41(7).
PMID: 38935572
Two important characteristics of metapopulations are extinction-(re)colonization dynamics and gene flow between subpopulations. These processes can cause strong shifts in genome-wide allele frequencies that are generally not observed in "classical"...

Cornetti L, Fields P, Du Pasquier L, Ebert D
Nat Commun
. 2024 Jun;
15(1):5333.
PMID: 38909039
Balancing selection is an evolutionary process that maintains genetic polymorphisms at selected loci and strongly reduces the likelihood of allele fixation. When allelic polymorphisms that predate speciation events are maintained...

Genome Biol Evol
. 2024 May;

PMID: 38776329
We have sequenced, assembled, and analyzed the nuclear and mitochondrial genomes and transcriptomes of Potamopyrgus estuarinus and Potamopyrgus kaitunuparaoa, two prosobranch snail species native to New Zealand that together span...

PMID: 37862134
The angiosperm genus Silene has been the subject of extensive study in the field of ecology and evolution, but the availability of high-quality reference genome sequences has been limited for...

bioRxiv
. 2023 Sep;
PMID: 37732249
Significance: Whole-genome sequences have been largely lacking for species in the genus even though these flowering plants have been used for studying ecology, evolution, and genetics for over a century....

PMID: 37565496
Microsporidia are intracellular parasitic fungi whose genomes rank among the smallest of all known eukaryotes. A number of outstanding questions remain concerning the evolution of their large-scale variation in genome...

PMID: 37326294
Understanding the genomic basis of infectious disease is a fundamental objective in co-evolutionary theory with relevance to healthcare, agriculture, and epidemiology. Models of host-parasite co-evolution often assume that infection requires...
