Abstract

Genista anglica L. (Fabaceae) is a Western European plant, widespread from Northern Morocco to Southern Sweden, with two geographically isolated populations in Calabria (Italy). Based on morphological characters, some authors considered the southern Italian populations as two different species: Genista silana and Genista brutia. Recent phylogeographical studies reveal that the G. silana and G. brutia populations share genetic similarities with some populations of the widespread G. anglica from Northwestern of Iberian Peninsula, despite a distance of approximately 2000 km. Previously, other authors suggested anthropogenic introduction of these plants in the South of Italy, but this hypothesis has not been thoroughly investigated. To unravel the uncertain origin of the isolated Italian populations, we conducted a more detailed study about the genetic relationships between southern Italian populations and Northwestern of Iberian Peninsula populations of G. anglica s.l., using plastid DNA sequences. Our results show identical and similar haplotypes in some of the populations of the Northwestern of Iberian Peninsula and the Italian populations, which supports the hypothesis of a recent anthropogenic introduction.

Genista anglica s.l.（豆科）：伊比利亚种群和意大利种群的遗传相似性

Genista anglica L.（豆科）是一种西欧植物，广泛分布于摩洛哥北部到瑞典南部，在卡拉布里亚（意大利）有两个地理上孤立的种群。根据形态特征，一些作者认为意大利南部的种群是两个不同的物种：Genista silana 和 Genista brutia。最近的系统地理学研究表明，尽管相距约 2000 千米，G. silana 和 G. brutia 种群与伊比利亚半岛西北部广泛分布的 G. anglica 种群具有遗传相似性。此前，其他作者认为这些植物是人为引入意大利南部的，但这一假设尚未得到深入研究。为了解开意大利孤立种群的不确定起源，我们利用质粒 DNA 序列对意大利南部种群与伊比利亚半岛西北部种群之间的遗传关系进行了更详细的研究。我们的研究结果表明，伊比利亚半岛西北部的一些种群与意大利种群的单倍型相同或相似，这支持了近期人为引入的假说。

期刊介绍： Phytotaxa is a peer-reviewed, international journal for rapid publication of high quality papers on any aspect of systematic and taxonomic botany, with a preference for large taxonomic works such as monographs, floras, revisions and evolutionary studies and descriptions of new taxa. Phytotaxa covers all groups covered by the International Code of Nomenclature foralgae, fungi, and plants ICNafp (fungi, lichens, algae, diatoms, mosses, liverworts, hornworts, and vascular plants), both living and fossil. Phytotaxa was founded in 2009 as botanical sister journal to Zootaxa. It has a large editorial board, who are running this journal on a voluntary basis, and it is published by Magnolia Press (Auckland , New Zealand). It is also indexed by SCIE, JCR and Biosis. All types of taxonomic, floristic and phytogeographic papers are considered, including theoretical papers and methodology, systematics and phylogeny, monographs, revisions and reviews, catalogues, biographies and bibliographies, history of botanical explorations, identification guides, floras, analyses of characters, phylogenetic studies and phytogeography, descriptions of taxa, typification and nomenclatural papers. Monographs and other long manuscripts (of 60 printed pages or more) can be published as books, which will receive an ISBN number as well as being part of the Phytotaxa series.
