The complete chloroplast genome of Ocimum americanum Linnaeus 1755 and phylogenetic analysis among the Lamiaceae family

Figures & data

Figure 1. Reference image of the Ocimum americanum plant used in this study. This image was taken by the authors (Suresh Vineesh and Raju Balaji).

Figure 2. Circular map of the chloroplast genome of Ocimum americanum. From the center going outward, the first circle shows the distribution of the repeats connected with red (the forward direction) and green (the reverse direction) arcs. The second circle displays the tandem repeats marked with short bars. The third circle shows the LSC, SSC, IRa, and IRb regions. The fourth circle shows the percentage of GC content. The next circle shows the genes having different colors based on the functional groups. The functional classification is shown at the bottom left. Genes inside the circle are transcribed in a clockwise direction, and those outside are in a counter-clockwise direction.

Figure 3. Phylogenetic tree based on the whole chloroplast genome sequences of 13 species from Lamiaceae family, including the chloroplast genome of O. americanum (OQ689804) from this study. Nicotiana tabacum (Solanaceae) was used as an outgroup. The bootstrap support values are shown on the nodes. The following sequences were used: O. americanum OQ689804.1 (this study), O. gratissimum MW348919.1 (Balaji et al. 2021), O. basilicum OQ706275.1 (Rabah et al. 2017), O. tenuiflorum MW829604.1 (Harini et al. 2021), O. kilimandscharicum MW829603.2 (Renald et al. 2021), Plectranthus barbatus ON641315.1, Isodon nervosus OM617841.1, Perilla frutescens KT220691.1, Mentha longifolia KU956042.1 (Vining et al. 2017), Salvia japonica KY646163.1 (He et al. 2017), Premna microphylla KM981744.1 (Yang and Kong 2016), Ballota nigra ON641319.1, Cymaria dichotoma MT473753.1 (Zhao et al. 2021), and Nicotiana tabacum Z00044.2 (Shinozaki et al. 1986).
