Association between the mutation of gene PRUPE_2G242400/euAP2a, which as a 983-bp deletion and the mutant flower phenotype in the LFP. (a-k) Expression profiles of the indicated genes in floral buds during chilling (blue) and warm (light orange) treatments. (l-m) The alteration of RNA-seq read mapping pattern in PRUPE_6G347800/ERA1b (l) and PRUPE_6G242400/euAP2a (m) regions in LFP buds, respectively.The exon number and position on the euAP2a are indicated by number and highlighted in yellow. The absence of or altered read mapping patten in the LFP flower buds are denoted by blue squares. Arrows indicate the gene transcription direction. (n) Survey of the genome sequence change in genes among 15 different assembled peach genomes. Two A to C transversions, one 10-bp insertion, and 983bp- and 2456bp-deletion events in four genes are depicted in the left panel, with (+) and (-) signifying the presence and absence of the mutation events in each genome. The Bioproject ID numbers (red) of each genome sequence are numbered and presented in the bottom panel.
