Intraspecific genetic variation modulates immune responses to acute heat exposure in an aquatic ectotherm

The paper examines how genetic variation within a snail species affects immune responses to heat stress, finding trait-specific and genotype-dependent immune suppression under heatwave conditions.

Achiasmatic meiosis underlies propagation of clonal genome and B chromosomes in hexaploid Carassius gibelio females but not males

The paper shows that hexaploid Carassius gibelio females use achiasmatic meiosis to produce clonal eggs, while males have reduced fertility due to meiotic issues, and B chromosomes are stably inherited as univalents.

Characterization of nuclear genome size and variation in a freshwater snail model system featuring a recent whole-genome duplication

The paper measures nuclear genome size variation in Potamopyrgus antipodarum, finding higher genome content in sexual individuals and evidence for a recent whole-genome duplication.

The haplotype-resolved Prymnesium parvum (type B) microalga genome reveals the genetic basis of its fish-killing toxins

The paper assembles the first haplotype-resolved diploid genome of Prymnesium parvum type B, identifies genomic differences linked to toxin variation, and provides insights into strain diversity and toxin production mechanisms.
