The challenge of allelic diversity for assembling haplotypes is exemplified in polyploid genomes containing homoeologous chromosomes of identical ancestry, and significant homologous variation within their ancestral subgenomes. Cultivated strawberry (Fragaria × ananassa) and its progenitors are outbred octoploids in which up to eight homologous and homoeologous alleles are preserved. This introduces significant risk of haplotype collapse, switching, and chimeric fusions during assembly. Using third generation HiFi sequences from PacBio, we assembled the genome of the...

Mucilage-binding to ground protects seeds of many plants from harvester ants: a functional investigation

Vincent Pan, Marshall McMunn, Richard Karban, Jake Goidell, Eric LoPresti & Marjorie Weber
The seeds of many plant species produce mucilage on their surfaces that when wetted and dried, firmly adheres seeds to surfaces and substrates. Previous studies have demonstrated that seed anchorage to the ground can reduce seed predation, though only a few species have thus far been tested. Here we investigated whether binding to the ground reduces seed removal by harvester ants (Pogonomyrmex subdentatus), an important granivore, for 53 species with mucilaginous seeds. We also explored...
