Complete chloroplast genomes of ten wild Fragaria species native to China were sequenced. Phylogenetic analysis clustered Fragaria species into two clades: The south clade (F. iinumae, F. chinensis, F. pentaphylla, F. nilgerrensis, F. daltoniana, F. corymbosa, F. moupinensis, F. tibetica, F. nipponica, F. gracilis, and F. nubicola and north clade (F. viridis, F. orientalis, F. moschata, F. mandshurica, F. vesca, F. chiloensis, F. virginiana, and F. × ananassa), while F. iinumae is the oldest extant species. Molecular clock analysis suggested present Fragaria species share a common ancestor 3.57 million years ago (Ma), F. moschata and octoploid species evolve 0.89 and 0.97 Ma, respectively, but F. moschata be not directly involved in current octoploid species formation. Drastic global temperature change since the Palaeocene-Eocene, approx. 55 Ma, especially during uplifting of the Qinghai-Tibet plateau and quaternary glaciation may have driven the formation of Fragaria, separation of two groups and polyploidization.
对原产于中国的10种野生草莓的完整叶绿体基因组进行了测序。系统发育分析将草莓属物种分为两个进化枝:南进化枝(野草莓、中华草莓、五叶草莓、黄毛草莓、西藏草莓、伞房草莓、茂汶草莓、西南草莓、日本草莓、纤细草莓和云莓)和北进化枝(绿草莓、东方草莓、麝香草莓、东北草莓、森林草莓、智利草莓、弗州草莓和凤梨草莓),而野草莓是现存最古老的物种。分子钟分析表明,现存的草莓属物种在357万年前有一个共同祖先,麝香草莓和八倍体物种分别在89万年前和97万年前进化,但麝香草莓并非直接参与当前八倍体物种的形成。自古新世 - 始新世(约5500万年前)以来剧烈的全球温度变化,特别是在青藏高原隆升和第四纪冰川作用期间,可能推动了草莓属的形成、两组的分离和多倍体化。
