Genome sequencing of 'Fuji' apple clonal varieties reveals genetic mechanism of the spur-type morphology.

ABSTRACT: Somatic variations can give rise to bud sports with advantageous traits, serving as the foundation for bud sport breeding in perennial plants. Here, we report a fully phased genome assembly of 'Fuji' apple, enabling comprehensive identification of somatic variants across 74 clonally propagated 'Fuji' varieties. Phylogenetic analysis indicates that spur-type and early-maturation traits in 'Fuji' sport varieties arise from multiple independent events. Several putative functional somatic variants have been identified, including a spur-type-specific deletion in the promoter of the TCP transcription factor gene MdTCP11. DNA methylation level of the deletion-associated miniature inverted-repeat transposable element is lower in spur-type varieties compared to standard-type varieties, while the ex
