The plot thickens: haploid and triploid-like thalli, hybridization, and biased mating type ratios in Letharia

S. L. Ament-Velasquez, V. Tuovinen, L. Bergström, T. Spribille, D. Vanderpool, J. Nascimbene, Y. Yamamoto, G. Thor, H. Johannesson

The paper investigates the reproductive biology of Letharia fungi, finding haploidy in some specimens and triploid-like features in others, suggesting hybridization and asexual reproduction in certain regions.

Meiotic drive is associated with sexual incompatibility in Neurospora

A. A. Vogan, J. Svedberg, M. Grudzinska-Sterno, H. Johannesson

The paper shows that meiotic drivers Sk-2 and Sk-3 in Neurospora intermedia cause sexual incompatibility with N. metzenbergii, reducing viable progeny.

Invasion and maintenance of meiotic drivers in populations of ascomycete fungi

i. martinossi, C. Veller, S. L. Ament-Velasquez, A. Vogan, C. Rueffler, H. Johannesson

The paper develops a population genetic model to study the invasion and coexistence of meiotic drivers in ascomycete fungi, focusing on spore killing and its dependence on ploidy, selfing rate, and spore killing efficiency.

An introgressed gene causes meiotic drive in Neurospora sitophila

J. Svedberg, A. A. Vogan, N. A. Rhoades, D. Sarmarajeewa, D. J. Jacobson, M. Lascoux, T. M. Hammond, H. Johannesson

This study identifies a gene responsible for meiotic drive in Neurospora sitophila and shows it was introgressed from a related species.
