Abstract:
We have assembled the complete sequence of the Durio zibethinus chloroplast genome using long PacBio reads. Durian is a valuable commercial tree that produces durian fruit, which is popular in Southeast Asia. The chloroplast genome assembled into a single 143 kb cyclic contig that contained 111 genes. There were 46 short direct repeats (45 to 586 bp) and five short inverted repeats (63 to 169 bp). The long reads that were used for the assembly span the entire chloroplast with > 10 kb overlaps and multiple long reads join the start of the contig to the end of the contig. The durian chloroplast was found to lack the large inverted repeat that is common in chloroplast genomes. An additional 24 durian varieties were sequenced and compared to the assembly and found to also lack the large inverted repeat. There were nine SNPs among the varieties.
