ABSTRACT
Senna alata, a flowering shrub, is widely cultivated in the Philippines for its anti-fungal properties. Despite this, its chloroplast genome is not yet established. We assembled and annotated the complete chloroplast genome of accession from the germplasm collection of the Institute of Crop Science, University of the Philippines, Los Baños, using Illumina sequencing data. The complete cp genome was 159,176-bp long characterized by a large single copy of 88,769 bp, short single-copy of 18,301 bp and a pair of inverted repeat regions of 26,053 bp each. The overall GC content of the chloroplast genome was 36.4%. The plastome comprised 37 tRNA genes, 8 rRNA genes and 78 mRNA genes. Phylogenetic analysis showed that S. alata is closely related to S. siamea.
ABSTRACT
The three-leaved chaste tree (Vitex trifolia) is a medicinal and ornamental plant widely distributed from East Africa to the Pacific but has no complete chloroplast genome sequence. We assembled and characterized the V. trifolia accession from the germplasm collection of the Institute of Crop Science, University of the Philippines Los Baños. The complete plastome sequence is 154,444-bp long with 131 coding genes comprising 87 mRNA genes, 36 tRNA genes, and 8 rRNA genes. A phylogenetic analysis of the assembled genome, together with nine other Lamiaceae species, identified V. rotundifolia as its closest relative with available complete cpDNA sequence. The clustering also supports the genotypic similarity of the species belonging to trifolia group of the genus Vitex.
