Silene latifolia is an herbaceous plant with great invasive potential. Spread along trade routes from Europe to almost all continents, white campion became particularly widespread in North America. We sequenced the chloroplast genome of S. latifolia subsp. alba from a native range in southeast Fennoscandia. The chloroplast genome of native S. latifolia subsp. alba forms a 151,747-bp circle, has two inverted repeat regions (25,993 bp each), large single copy (82,708 bp), and small single copy (17,106 bp) regions. It contains 77 protein-coding genes, 30 tRNA genes, and four rRNA genes. SSRs and long DNA repeats were identified. Comparison of a newly sequenced plastome of S. latifolia subsp. alba with plastomes of invasive specimens of species from North America and Japan revealed a high level of single nucleotide polymorphisms (SNPs) among them. A total of 214 SNPs were found, among which 110 were identified in intergenic spacers, 74 in exons, and 30 in introns. Intraspecific shifts in inverted repeat boundaries were identified. Our research suggests that high polymorphic regions may be potential molecular markers for population studies and that high intraspecific genetic polymorphism may contribute to a species’ invasive success.

Native Silene latifolia subsp的叶绿体基因组。来自 Fennoscandia 的 alba 与 Invasive White Campion 表现出高度差异

Silene latifolia 是一种具有巨大入侵潜力的草本植物。沿着从欧洲到几乎所有大陆的贸易路线传播，白色野菜在北美变得特别普遍。我们对阔叶亚种的叶绿体基因组进行了测序。alba 来自芬诺斯坎迪亚东南部的原生范围。天然 S. latifolia subsp. 的叶绿体基因组。alba 形成一个 151,747 bp 的环，具有两个反向重复区域（每个 25,993 bp）、大单拷贝（82,708 bp）和小单拷贝（17,106 bp）区域。它包含77个蛋白质编码基因、30个tRNA基因和4个rRNA基因。鉴定了 SSR 和长 DNA 重复序列。S. latifolia subsp. 新测序的塑性体的比较。带有来自北美和日本物种的入侵标本的塑性体的 alba 揭示了其中的高水平单核苷酸多态性 (SNP)。共发现214个SNP，其中110个位于基因间间隔区，74个位于外显子，30个位于内含子。鉴定了反向重复边界中的种内变化。我们的研究表明，高多态性区域可能是种群研究的潜在分子标记，高种内遗传多态性可能有助于物种的入侵成功。
