The fungal pathogen Rhizoctonia solani AG-8 has 2 nuclear haplotypes that differ in abundance.

ABSTRACT: The fungal pathogen Rhizoctonia solani infects a diverse range of host plants and remains an intractable and economically significant disease for many crops. R. solani is classified into reproductively incompatible anastomosis groups (AGs). In the vegetative stage, most plant-pathogenic R. solani isolates are multinuclear and heterokaryotic, but little was previously known about the diversity between haplotypes due to highly fragmented, collapsed short-read assemblies. We present fully-phased, chromosome-scale genome assemblies of the broad host-range R. solani isolates AG8-1 and AG8-3. We demonstrate that both AG8 isolates have 2 distinct haplotypes, each of which is ∼50 Mbp spread across 16 chromosomes and use PacBio Iso-Seq data to achieve a high-quality gene annotation. We show that th
