Abstract

Platycrater arguta Siebold & Zucc., is a monotypic Hydrangeaceae genus, yet its mitogenomic information remains limited. We assembled its mitogenome from PacBio HiFi reads: 435,757 bp (45.76% GC), containing 66 genes (36 protein-coding, 27 tRNA, 3 rRNA). Complex trans-splicing introns occurred in nad1, nad2 and nad5; codons were strongly AT-biased. It also had 100 large dispersed repeats (>50 bp), 26 tandem repeats and 136 SSRs. Using shared PCGs from 21 species, P. arguta fell within Hydrangeaceae, sister to Hydrangea macrophylla and H. chinensis (100% bootstrap). This mitogenome is a valuable resource for Hydrangeaceae phylogeny and comparative genomics.

第三纪孑遗灌木白花楸（绣球科）的全有丝分裂基因组及系统发育分析。

Platycrater arguta Siebold & Zucc。是绣球科的一个单型属，但其有丝分裂基因组信息仍然有限。我们从PacBio HiFi中组装了它的有丝分裂基因组：435,757 bp (45.76% GC)，包含66个基因（36个蛋白质编码，27个tRNA， 3个rRNA）。nad1、nad2和nad5中存在复杂的反式剪接内含子；密码子具有强烈的at偏倚性。它还具有100个大分散重复序列（bbb50 bp）， 26个串联重复序列和136个ssr。对21种植物的共有PCGs进行分析，结果表明，软叶绣球属绣球科，是大绣球和中国绣球的姐妹植物（100% bootstrap）。该有丝分裂基因组是绣球科系统发育和比较基因组学研究的宝贵资源。
