Abstract：
Bixa orellana is a small tree known for its red, oil-soluble pigment contained in the seed coat that is used as a natural dye and food coloring. In this study, we assembled and characterized the complete chloroplast genome of B. orellana as a resource for future genetic studies. With a total length of 159,825 bp, the chloroplast genome comprised of a large single-copy (LSC) region of 89,476 bp, a small single-copy (SSC) region of 19,617 bp, and two inverted repeat (IR) regions of 25,356 bp each. A total of 127 genes were predicted, consisting of 83 protein-coding genes, 36 tRNA genes, and 8 rRNA genes. Phylogenetic analysis confirmed the position of B. orellana within the order Malvales.
摘要：
Bixaorellana是一棵以红色闻名的小树，包含在种皮中的油溶性色素，用作天然染料和食用色素。在这项研究中,我们组装并表征了B.orellana完整的叶绿体基因组，作为未来遗传研究的资源。总长度为159,825bp，叶绿体基因组由89,476bp的大型单拷贝(LSC)区域组成，一个19,617bp的小的单拷贝(SSC)区域，和两个每个25,356bp的反向重复(IR)区。共预测127个基因,由83个蛋白质编码基因组成，36个tRNA基因，和8个rRNA基因。系统发育分析证实了拟南芥在拟南芥中的位置。
