abstract = {Cultivated potato is a clonally propagated autotetraploid
species with a highly heterogeneous genome. Phased
assemblies of six cultivars including two chromosome-scale
phased genome assemblies revealed extensive allelic
diversity, including altered coding and transcript
sequences, preferential allele expression, and structural
variation that collectively result in a highly complex
transcriptome and predicted proteome, which are distributed
across the homologous chromosomes. Wild species contribute
to the extensive allelic diversity in tetraploid cultivars,
demonstrating ancestral introgressions predating modern
breeding efforts. As a clonally propagated autotetraploid
that undergoes limited meiosis, dysfunctional and
deleterious alleles are not purged in tetraploid potato.
Nearly a quarter of the loci bore mutations are predicted to
have a high negative impact on protein function,
complicating breeder’s efforts to reduce genetic load. The
StCDF1 locus controls maturity, and analysis of six
tetraploid genomes revealed that 12 allelic variants of
StCDF1 are correlated with maturity in a dosage-dependent
manner. Knowledge of the complexity of the tetraploid potato
genome with its rampant structural variation and embedded
deleterious and dysfunctional alleles will be key not only
to implementing precision breeding of tetraploid cultivars
but also to the construction of homozygous, diploid potato
germplasm containing favorable alleles to capitalize on
heterosis in F1 hybrids.},
