In this work, we identified non-crustose invasive ( Codium fragile subsp. fragile ) and native Codium spp. ( Codium tomentosum and Codium vermilara ) in the central Cantabrian Sea using DNA barcoding (tufA and rbcL genes). We designed a new FCO tuf A genetic marker for identifying Codium spp. in fresh and herbarium material. The tufA and rbcL sequences revealed three different single haplotypes for each of the species and a lack of intraspecific genetic diversity. The FCO tuf A genetic marker revealed one new haplotype of C. fragile within the native region (South Korea), suggesting the possibility of higher genetic diversity in the donor region of this invasive species.

基于DNA条形码的比斯开湾南部坎塔布连海中侵入性和原生非硬壳Co物种的评估

在这项工作中，我们确定了非硬壳侵入性（脆弱的小球藻亚种）和天然的孢子菌。坎塔布连海中部的绒毛虫（todium tomentosum and vermilara）（tufA和rbcL基因）。我们设计了一种新的FCO tuf A遗传标记物，用于鉴定Co。在新鲜和植物标本室材料中。tufA和rbcL序列揭示了每种物种的三种不同的单倍型，并且缺乏种内遗传多样性。FCO tuf A遗传标记揭示了本地区域（韩国）内一种脆弱的梭状芽胞杆菌的新单倍型，这表明该入侵物种的供体区域可能具有更高的遗传多样性。
