Abstract

Primulina ophiopogoides is a perennial herb of Gesneriaceae distributed on the limestone rocks. Here, the complete chloroplast (cp) genome of P. ophiopogoides was assembled and characterized. The cp genome is in a total length of 152,718 bp with the typical quadripartite structure, containing 2 inverted repeats (IRs) of 25,472 bp separated by a large single-copy (LSC) region of 83,615 bp and a small single-copy (SSC) region of 18,159 bp. The whole cp genome of P. ophiopogoides contains 131 genes, including 86 protein-coding genes, 37 tRNAs genes, and 8 rRNAs. The phylogenetic analysis indicated that P. ophiopogoides displayed a closer kinship to Primulina linearifolia.

摘要

Primulina ophiopogoides是分布在石灰石岩石上的多年生草本植物。在这里，完整的叶绿假单胞菌叶绿体（cp）基因组进行了组装和表征。cp基因组的全长为152,718 bp，具有典型的四方结构，包含2个25,472 bp的反向重复序列（IR），分别由83,615 bp的大单拷贝（LSC）区域和小单拷贝（SSC）隔开18,159 bp的区域。ophophpogoides的整个cp基因组包含131个基因，包括86个蛋白质编码基因，37个tRNA基因和8个rRNA。系统进化分析表明，ophiopogoides与樱草属亲缘关系较近。
