Complete chloroplast genome sequence and phylogenetic analysis of Syzygium malaccense

Abstract

Syzygium malaccense is native to Malaysia. It is sometimes called the malay apple, malay rose-apple, mountain rose-apple, mountain apple, water apple, or French cashew. The tree is very popular in many tropical and subtropical regions for its fruit and traditional medicine. The first complete chloroplast genome of Syzygium malaccense has been reported in this study. The complete chloroplast genome of Syzygium malaccense is 158,954 bp, composed of four regions: a large single-copy region with a size of 87,991 bp, a small single copy region with a size of 18,793 bp, and two inverted repeat regions with a size of 26,085 bp. The GC content is 36.97%. A total of 132 genes were annotated, including 84 encoding proteins, eight encoding rRNA genes, 37 encoding tRNA genes, and three encoding pseudo genes. Phylogenetic analysis showed that Syzygium aromaticum, Syzygium cumini, and Syzygium forrestii are closely related to Syzygium malaccense.

Genome sequencing of Syzygium cumini (Jamun) reveals adaptive evolution in secondary metabolism pathways associated with its medicinal properties

“…The chloroplast genome assembly of S. cumini showed a circular genome of 158,509 bases with 86 protein-coding genes (Supplementary Figure 3). The assembled genome assembly and annotation statistics (Supplementary Table 4) were similar to the previously reported chloroplast genomes of S. cumini and other Syzygium species [61,62].…”

Genome sequencing of Syzygium cumini (jamun) reveals adaptive evolution in secondary metabolism pathways associated with its medicinal properties

“…The chloroplast genome assembly of S. cumini showed a circular genome of 158,509 bases with 83 protein-coding genes ( Supplementary Figure 4 ). The assembled genome size was comparable to the S. malaccense chloroplast genome ( Tao et al., 2020 ). However, the previously reported S. cumini chloroplast genome size ( Asif et al., 2013 ) was larger compared to this study, and also larger than the other two S. cumini chloroplast genomes available at NCBI database (NCBI accessions: NC_053327.1 and MN095412.1) ( Supplementary Table 4 ).…”

The comparative statistics of the sizes of Large Single Copy (LSC), Small Single Copy (SSC), and Inverted Repeat (IR) regions of S. cumini chloroplast genomes in this study and the previous study ( Asif et al., 2013 ) and the chloroplast genome of S. malaccense ( Tao et al., 2020 ) are mentioned in Supplementary Table 4 . The LSC region in the S. cumini chloroplast genome provided by Asif et al., 2013 was larger compared to the other genomes available at NCBI database, the genome constructed in this study, and the S. malaccense chloroplast genome ( Tao et al., 2020 ).…”
