Sex Chromosome Turnover and Structural Interspecific Genome Divergence Shapes Meiotic Outcomes in Hybridizing Cobitis

S. A. Schlebusch, Vladimir A. Trifonov, Zuzana Halenková, Marharyta Klianitskaya, Dmitrij Dedukh, Aurora Ruiz‐Herrera, L. Alvarez Gonzalez, Gala Pujol, Eva Hřibová, Lucija Andjel, Oldřich Bartoš, Petr Pajer, Tomáš Tichopád, Daniel Kulik, Jan Kotusz, , Karel Janko

The paper presents chromosome-level genome assemblies for three hybridizing Cobitis species to study hybrid sterility and asexuality, revealing structural variation and sex chromosome divergence.

From asexuality to sexual reproduction: cyclical switch of gametogenic pathways in hybrids depend on ploidy level

D. Dedukh, A. Marta, R.-Y. Myung, M.-H. Ko, D.-S. Choi, Y.-J. Won, K. Janko

The paper investigates how hybridization and polyploidization affect gametogenesis in hybrids, showing ploidy-dependent shifts between asexual and sexual reproduction.

Differential CpG methylation at Nnat in the early establishment of beta cell heterogeneity

V. Yu, F. Yong, A. Marta, S. Khadayate, A. Osakwe, S. Bhattacharya, S. S. Varghese, P. Chabosseau, S. M. Tabibi, K. Chen, E. Georgiadou, N. Parveen, M. Suleiman, Z. Stamoulis, L. Marselli, , S. J. Millership

This study identifies differential CpG methylation at the Nnat gene as a mechanism establishing beta cell heterogeneity during development and its potential role in diabetes.

Sex chromosome differentiation via changes in the Y chromosome repeat landscape in African annual killifishes Nothobranchius furzeri and N. kadleci

J. Stundlova, M. Kreklova, K. Luksikova, A. Volenikova, T. Pavlica, M. Altmanova, M. Reichard, M. Dalikova, S. Pelikanova, A. Marta, S. A. Simanovsky, M. Hirman, M. Jankasek, T. Dvorak, J. Bohlen, , A. Sember

The paper investigates sex chromosome differentiation in two killifish species by analyzing repetitive DNA landscapes, revealing shared XY systems and alternative evolutionary mechanisms.

Parthenogenesis as a solution to hybrid sterility: the mechanistic basis of meiotic distortions in clonal and sterile hybrids

D. Dedukh, Z. Majtanova, A. Marta, M. Psenicka, J. Kotusz, J. Klima, D. Juchno, A. Boron, K. Janko

This paper investigates how parthenogenesis resolves hybrid sterility in fish hybrids, showing that female fertility is restored through premeiotic endoreplication while male sterility results from meiotic asynapses and reduced crossovers.
