Part of the Compendium of Plant Genomes book series (CPG)


Genome platform is critical to the basic molecular biological research and to the molecular marker assisted breeding. Genomics data of citrus species have accumulated rapidly after the first publication of sweet orange in 2013. With the cost of sequencing decreased dramatically, each individual research group can afford to sequence many genomes. This chapter summarizes methods for genome assembly and annotation, how we identify genes by comparative genomics, linkage mapping and association analysis, how we apply SNP markers in cultivar identification and breeding, and the current knowledge on epigenetic regulations in Citrus. This chapter also anticipates future genomic researches in Citrus.
