概括

菲洛斯蒂克塔 (Phyllosticta citricarpa) 和帕拉西特里卡帕 (P. paracitricarpa) 是同一个物种. 基因组分析显示,它们之间的变异是内属的,而不是不同物种的标志.

科学领域:

菌类学菌类学是指菌类学.
植物病理学植物病理学
基因组学就是基因组学.

背景情况:

菲洛斯蒂克塔 (Phyllosticta citricarpa) 是一个检疫类病原体.
密切相关的物种P. paracitricarpa不是一个隔离生物体.
区分P. citricarpa和P. paracitricarpa是具有挑战性的,因为重叠的形态和有限的遗传标记.

研究的目的:

为了确定P. citricarpa和P. paracitricarpa之间的遗传变异是否代表了类型内变异或不同的物种.
为了澄清P. paracitricarpa相对于P. citricarpa的分类学地位.

主要方法:

用3000个单复制的正统基因进行了基因组学分析.
整个基因组的比较.
对线粒体基因组组合的分析.

主要成果:

基因组分析表明,P. citricarpa和P. paracitricarpa之间的变化是不特定的.
在两者之间的线粒体组件中发现了最小的差异.
其他Phyllosticta物种内的物种内变异大于P. citricarpa和P. paracitricarpa之间观察到的变异.

结论:

P. citricarpa和P. paracitricarpa应该被认为是同种 (同一物种).
这一发现对隔离法规和病原体管理有影响.

Phylogeny

Phylogeny

Phylogeny is concerned with the evolutionary diversification of organisms or groups of organisms. A group of organisms with a name is called a taxon (singular). Taxa (plural) can span different levels of the evolutionary hierarchy. For instance, the group containing all birds is a taxon (comprising the class Aves), and the group of all species of daisies (the genus Bellis) is a taxon. Phylogenies can likewise include just one genus (i.e., depict species relationships) or span an entire kingdom.
