High-Quality Genome Assembly of Diplocarpon coronariae Unveils LTR Retrotransposon-Driven Structural Dynamics in Fungi Evolution.

ABSTRACT: Long terminal repeat retrotransposons (LTR-RTs) are recognised as a significant evolutionary force capable of shaping the structure and function of the genomes in eukaryotes, including animals, plants, and fungi. However, much remains largely unknown about how LTR-RTs influence the evolution of fungi at the chromosomal level. Here, we assembled the genome of an important plant pathogenic fungus, Diplocarpon coronariae (strain XN1), at the chromosomal level and obtained high-precision, full-length transcriptome annotations through transcriptome evidence and manual curation. Using high-quality genomes and gene annotations, we identified the two-speed genome and constructed a pan-genome graph of D. coronariae. Through comparative genomics, we discovered that LTR-RTs contributed to sequence an
