Haplotype-phased assemblies of the two poplar rust fungi species: Melampsora larici-populina and Melampsora allii-populina

Emma Corre, Emmanuelle Morin, Jana Sperschneider…·Cécile Lorrain

The paper presents haplotype-phased, near chromosome-scale genome assemblies for two poplar rust fungi species, improving contiguity and enabling analysis of genome architecture and virulence genes.

Long-lasting coexistence of multiple asexual lineages alongside their sexual counterparts in a fungal plant pathogen

Ammar Abdalrahem, Axelle Andrieux, Ronan Becheler…·Fabien Halkett

The paper studies the coexistence of asexual and sexual lineages in the poplar rust fungus over 30 years, finding persistent asexual lineages with genetic clonality and ecological structuring.
