Pepper genome sequence and variants
In this database, we provide high-quality reference genomes and annotations of three pepper cultivars, Zhangshugang (belonging to
Capsicum annuum var. annuum in the Annuum clade), PI 632928 (C. baccatum var. pendulumC. pubescens in the Pubescens clade). The genome and gene sequences and annotations can be searched, viewed and analyzed using tools implemented
in this database.
A graph pan-genome was constructed using the Zhangshugan genome as the reference and structural variants (SVs) identified in PI 632928 and Grif 1614 based on the alignments of their genomes to the Zhangshugan genome. A pepper variome was constructed by sequencing genomes of 500 core Capsicum accessions from C. annuum var. annuum (n = 90), C. annuum var. glabriusculum (n = 22), C. baccatum var. pendulum (n = 109), C. baccatum var. baccatum (n = 9), C. pubescens (n = 38), C. chacoense (n = 17), C. frutescens (n = 99), C. chinense (n = 115) and C. galapagoense (n = 1), and mapping the sequencing reads to the graph pan-genome. A total of about 100 million high-quality SNPs and 7.3 million small indels have been identified and these variants can be explored and analyzed using the 'Variant' module developed in this database.
