Chromosome-Level Genome Assembly and Annotation of the Highly Heterozygous <i>Phallus echinovolvatus</i> Provide New Insights into Its Genetics.

ABSTRACT: Phallus echinovolvatus is a well-known edible and medicinal fungus with significant economic value. However, the available whole-genome information is lacking for this species. The chromosome-scale reference genome (Monop) and two haploid genomes (Hap1 and Hap2) of P. echinovolvatus, each assembled into 11 pseudochromosomes, were constructed using Illumina, PacBio-HiFi long-read sequencing, and Hi-C technology. The Monop had a size of 36.54 Mb, with 10,251 predicted protein-coding genes and including 433 carbohydrate-active enzyme genes, 385 cytochrome P450 enzyme genes, and 42 gene clusters related to secondary metabolite synthesis. Phylogenetic and collinearity analysis revealed a close evolutionary relationship between P. echinovolvatus and Clathrus columnatus
