Other claims from this paper (8)
- Method / resource A haplotype-resolved near-complete reference genome of Kyoho was assembled at 480.32-489.47 Mb.
- Observation Kyoho is a segmental allotetraploid with about 71% V. vinifera and 29% V. labrusca ancestry.
- Observation A total of 67.3% of genes are shared among the four haplotypic genomes.
- Observation Kyoho has 9.8% haplotype-specific genes.
- Observation DNA methylation profiles did not differ significantly between genome ancestries Vl and Vv.
- Association Allele-specific splicing changes were correlated with ancestral origin across tissues (Vl: 1,529 vs. Vv: 2,052).
- Observation Integrative omics identified 2,307 differentially expressed ancestral alleles with AS bias but no genomic variant or methylation bias.
- Observation The AS-biased genes include key regulators of fruit ripening, such as ZEP, PIN, DOG1 and MYB.
