This study compares oogenesis in annual and non-annual killifishes, finding conserved developmental stages but divergent zona pellucida features in the annual species.

The paper examines gene expression in electroreceptor and mechanosensory organs of sturgeon, identifying shared and distinct molecular features of their ribbon synapses.

The paper investigates the role of Atoh1 and Foxg1 in the development of electroreceptors and hair cells in sterlet embryos, finding Atoh1 is required for both, while Foxg1 represses electroreceptor fate.

This study shows mitochondria are essential for primordial germ cell formation in sturgeons, but their function is not restricted to germ plasm origin.

The paper identifies Bmp5 as promoting ampullary organ development while Bmp signalling inhibits their overproduction in sterlet sturgeon.

The paper identifies 23 transcription factor genes involved in electrosensory and mechanosensory lateral line organ development in paddlefish and sterlet, with some genes restricted to specific organ types.

This study identifies Regeneration Initiating Cells (RICs) in Xenopus laevis tail regeneration using single cell and spatial transcriptomics, showing their role in initiating regeneration by modifying the extracellular matrix.

The paper uses TOMO-Seq to compare maternal RNA localization across four fish and amphibian species, revealing diverse localization patterns and poor correlation between vegetally localized genes.

The paper investigates the triggers of clonal gametogenesis in hybrids, finding that it is initiated by intrinsic signals in hybrid germ cells but requires a female gonadal environment for execution.
