Litchi chinensis cultivar:Feizixiao Genome sequencing and assembly. Litchi chinensis cultivar:Feizixiao

The genome of cultivar 'Feizixiao' was assembled into 15 pseudo-chromosomes, totaling ~470 Mb. High heterozygosity (2.27%) resulted in two complete haplotypic assemblies. 13,517 allelic genes (42.4%) were differentially expressed in diverse tissues. Analyses of 72 re-sequenced lychee genomes revealed two independent domestication events.

栽培品种‘Feizixiao’（妃子笑）的基因组被组装为15条假染色体（pseudo-chromosomes），总长度约470 Mb。该基因组的杂合度高达2.27%，因此成功获得两套完整的单倍型组装结果。共有13517个等位基因（占总基因的42.4%）在多种组织中呈现差异表达。对72份重测序荔枝基因组的分析显示，荔枝曾发生过两次独立的驯化事件。
