Hainan betel nut genome map released for the first time

Recently, the Coconut Research Institute of the Chinese Academy of Tropical Agricultural Sciences and BGI have completed the splicing and sequence analysis of the betel nut genome, and completed and announced the Hainan betel nut whole genome sequencing for the first time
.

In this study, through the combination of Illumina and PacBio data and Hi-C mapping technology, the assembly of the reference genome at the chromosome level of the "Reyan No.
1" betel nut was completed.
The betel nut genome size is 2.
51Gb, and the scaffold N50 is 1.
7Mb.
Hi-C assisted assembly technology is further assembled into a genome of 16 chromosomes, with an N50 of 172Mb
.

Research and analysis found that the betel nut genome contains 31,571 protein-coding genes, 92.
92% of the genes are functionally annotated, and the gene families involved in the biosynthesis of arecoline, flavonoids, anthocyanins, monoterpenes and their derivatives show varying degrees of enrichment And expansion
