Genetic architecture of cichlid brain morphology

The paper investigates the genetic architecture of brain morphology in cichlid fish, showing modular genetic control of brain components and weaker genetic correlations in hybrids.

fgf8a signalling shapes brain divergence between Malawi cichlids

This study identifies fgf8a as a key gene driving brain divergence in Lake Malawi cichlids through species-specific enhancer elements and functional experiments.

Introgression dynamics of sex-linked chromosomal inversions shape the Malawi cichlid adaptive radiation

The paper analyzes 1,375 Malawi cichlid genomes to show that sex-linked chromosomal inversions drive adaptive speciation through introgression and selection on neuro-sensory, physiological, and reproductive genes.

Developmental plasticity and variability in the formation of egg-spots, a pigmentation ornament in the cichlid Astatotilapia calliptera

The paper investigates egg-spot formation in Astatotilapia calliptera, showing plasticity in initiation timing and cell-autonomous interactions between iridophores and xanthophores.

oca2 targeting using CRISPR/Cas9 in the Malawi cichlid Astatotilapia calliptera

This study uses CRISPR/Cas9 to edit the oca2 gene in Astatotilapia calliptera, demonstrating efficient germline transmission and phenotypic effects on melanin synthesis.
