Abstract

Fraxinus hupehensis is a national rare and Endangered tree in the Oleaceae family, that has high commercial value owing to its slow growth, interlaced roots, intricate tree shape, and easy to shape. Here, we determined the complete chloroplast (cp) genome sequence for F. hupehensis using genome skimming sequencing. The cp genome was 155,698 bp and consisted of a large single copy (LSC) region (86,498 bp), a small single copy (SSC) region (17,803 bp) and two inverted repeats (IRs) (25,694 bp). It encodes 131 genes, including 88 protein-coding genes, 8 rRNAs and 35 tRNAs. Phylogenetic analysis indicates that F. hupehensis was relatively closely related to F. chinensis compared to other species in the Oleaceae family.

摘要

胡桃水曲柳是油木科中的一种国家珍稀濒危树种，由于其生长缓慢，根系交错，树形复杂且易于成形，因此具有很高的商业价值。在这里，我们确定了完整的叶绿体（CP）的基因组序列F.甜茶利用基因组测序撇。cp基因组为155,698 bp，由一个大的单拷贝（LSC）区（86,498 bp），一个小的单拷贝（SSC）区（17,803 bp）和两个反向重复（IR）（25,694 bp）组成。它编码131个基因，包括88个蛋白质编码基因，8个rRNA和35个tRNA。系统发育分析表明，与油菜科中的其他物种相比，平邑甜茶与中华F的亲缘关系相对较近。
