Reproductive Adaptation of Astyanax mexicanus Under Nutrient Limitation

This study investigates reproductive adaptations in Astyanax mexicanus under nutrient limitation, finding cavefish maintain breeding ability under starvation due to increased maternal nutrient deposition and specific gene expression changes.

Long-term hybridization in a karst window reveals the genetic basis of eye loss in cavefish

The paper identifies a specific SNP in Cx50 linked to eye loss in cavefish using a hybrid population from a karst window.

Next-generation plasmids for transgenesis in zebrafish and beyond

The paper introduces next-generation transgenesis tools for zebrafish and other species, including vectors with fluorescent markers and promoters for specific tissue expression.

A non-functional copy of the salmonid sex determining gene (sdY) is responsible for the "apparent" XY females in Chinook salmon, Oncorhynchus tshawytscha.

The study identifies a non-functional sdY gene variant in XY Chinook salmon females that disrupts testicular differentiation by impairing estrogen synthesis.

A Transgenic System for Targeted Ablation of Reproductive and Maternal-Effect genes

The paper develops reverse genetic systems to identify essential maternal-effect genes and tests them by disrupting kif5Ba and bucky ball.

Zebrafish dazl regulates cystogenesis upstream of the meiotic transition and germline stem cell specification and independent of meiotic checkpoints.

This study shows that zebrafish dazl is essential for cystogenesis, germline stem cell specification, and fertility by regulating incomplete cytokinesis and meiotic entry.
