SMRT sequencing generates the chromosome-scale reference genome of tropical fruit mango, Mangifera indica

Abstract

Mango (Mangifera indica), a member of the family Anacardiaceae, is one of the worlds most popular tropical fruits. Here we sequenced the variety, "Hong Xiang Ya", and generated a 371.6-Mb mango genome assembly with 34,529 predicted protein-coding genes. Aided with the published genetic map, for the first time, we assembled the M. indica genome to the chromosomes, and finally about 98.77% of the genome assembly was anchored to 20 pseudo-chromosomes. The availability of the chromosome-length genome assembly of M. indica will provide novel insights into genome evolution, understand the genetic basis of specialized phytochemical composites relevant to fruit quality, and enhance allele mining in genomics-assisted breeding for mango genetic improvement.
