The complete chloroplast genome of Mitella nuda (Saxifragaceae)

The genus Mitella L. 1753 belongs to the family Saxifragaceae. Studying the chloroplast genome of Mitella is of great significance for understanding the phylogeny within the Heuchera group. This study reports the chloroplast genome of Mitella nuda, which has a total length of 155,409 bp. The chloroplast genome contains 131 genes. The phylogenetic tree indicates that Mitella is not monophyletic and exhibits clear phylogenetic relationships with Heuchera and Tiarella. This study not only enriches the genomic data for Mitella but also provides valuable data support for evolutionary studies within the Saxifragaceae family.

唢呐草属（Mitella L.，1753）隶属于虎耳草科（Saxifragaceae）。针对唢呐草属叶绿体基因组（chloroplast genome）的研究，对于明晰矾根类群（Heuchera group）内部的系统发育关系具有重要价值。本研究报道了裸花唢呐草（Mitella nuda）的叶绿体基因组，其总长度为155409 bp。该叶绿体基因组共包含131个基因。系统发育树分析结果表明，唢呐草属并非单系类群，且与矾根属（Heuchera）、黄水枝属（Tiarella）存在明确的系统发育亲缘关系。本研究不仅丰富了唢呐草属的基因组数据资源，同时也为虎耳草科内的进化生物学研究提供了宝贵的数据支撑。
