分析Myrcia Lundiana Kiaersk本地人口的遗传多样性。使用ISSR标记的植物。

Myrcia Lundiana Kiaersk。是在南半球的热带和亚热带地区发现的一棵树，可产生精油。这项研究的目的是使用简单间序列重复分子标记物来表征来自Parque nacional de Itabaiana的本地人群的伦迪亚纳植物的遗传多样性。测试了35个引物，其中20个是多态性的，产生了135个多态性和信息性带。群集分析的结果，使用具有算术平均值的未加权对组方法将植物分为三个簇：群集I -MLU001，MLU002，MLU003，MLU004，MLU004，MLU005，MLU006，MLU006，MLU006，MLU018，MLU018，MLU019，MLU019，MLU019，MLU020，MLU020，MLU021，MLU021，MMLU021，MMLU021，MMMLU022;MLU008，MLU011，MLU012，MLU014，MLU015，MLU017，MLU026和MLU028;集群II -MLU007，MLU009，MLU010，MLU013和MLU016;和集群III -MLU023，MLU024，MLU025和MLU027。Jaccard的相似性系数用于植物的成对比较，范围为0.15至0.87。MLU014和MLU015的遗传多样性低，相似性指数为0.87。 Conversely, MLU007 and MLU019 presented high diversity, with a similarity index of 0.15. According to the structure analysis, three distinct clusters were formed. Genetic diversity of M. lundiana plants was intermediate, and expansion of its genetic diversity is necessary. MLU026 and MLU028 are the most suitable for selection in breeding programs, since they clearly represent all of the diversity present in these plants. Moreover, these results provide important information on the existing genetic variability, highlighting the importance of Parque Nacional de Itabaiana for the conservation of this species.
