Project description:Dikaryotic rust fungi maintain two distinct haploid nuclei for most of their life cycle, making their large, repeat-rich genomes difficult to assemble and phase. Here we present haplotype-phased, near chromosome-scale genome assemblies for the poplar rust pathogens Melampsora larici-populina 98AG31 and Melampsora allii-populina 12AY07, generated using PacBio HiFi sequencing and Hi-C-guided scaffolding. For each species, we resolve 18 chromosomes per haplotype, providing the first chromosome-level representations of poplar rust fungal species. M. larici-populina diploid assembly spans ~203 Mb, while M. allii-populina reaches ~416 Mb, with high completeness and strong collinearity between haplotypes.
Project description:To facilitate new studies in the Amaryllidoideae subfamily, we present AmarylOmicBase, a unified transcriptomic database that integrates assemblies, annotations, and expression profiles from 39 studies, covering 27 Amaryllidoideae species and 4 hybrid cultivars across 13 genera of Amaryllidoideae. The AmarylOmicBase (v2, https://doi.org/10.5281/zenodo.20349158) includes de novo assemblies generated from published raw data using Trinity or IsoSeq workflows and provides standardized functional annotation (trinotate) and quantitative expression datasets.
