Abstract

The complete chloroplast genome sequence of the Cymbidium hybrid, C. sinense (♀) × C. goeringii (♂) was assembled in this study. The circular genome was 150,149 bp in length with an overall GC content of 37.1% and consisted of a pair of 25,691 bp inverted repeats, and two single-copy regions that were 84,987 bp and 13,780 bp, respectively. Gene annotation analysis identified 109 genes including 75 protein-coding genes, 30 transfer RNA, and 4 ribosomal RNA genes. Phylogenetic analysis showed its closest relationship to Cymbidium sinense, reflecting a maternal inheritance of chloroplasts.

摘要

在本研究中，组装了大花ym兰杂交种C. sinense（♀）× Goeringii（♂）的完整叶绿体基因组序列。环状基因组的长度为150,149 bp，GC总含量为37.1％，由一对25,691 bp的反向重复序列和两个分别为84,987 bp和13,780 bp的单拷贝区域组成。基因注释分析确定了109个基因，包括75个蛋白质编码基因，30个转移RNA和4个核糖体RNA基因。系统发育分析表明它与大花ym兰最密切的关系，反映了母体叶绿体的遗传。
