Fig. 1From: Genome-wide identification and transcriptome profiling reveal that E3 ubiquitin ligase genes relevant to ethylene, auxin and abscisic acid are differentially expressed in the fruits of melting flesh and stony hard peach varietiesGenomic distribution and duplication of the PpE3 ligase genes across the 8 chromosomes of peach. The E3 genes are shown with the chromosome on which the occur. Syntenic pairs are linked with lines, with colors representing each subfamily: BTB, blue; Cullin, orange; DDB, yellow; F-box, green; HECT, cyan; RING, red; SKP magenta; and U-box, purple. Each concentric layer represents a type of gene duplication: Layer 0 represents DSD; Layer 1, tandem duplication (TD); Layer 2, whole-genome duplication (WGD); Layer 3, proximal pairs (PD); and Layer 4, singletonsBack to article page
