背景情况:

棕色腐烂病是由Monilinia spp.引起的,严重影响全球果和石头果产量,导致收获前后的经济损失.
关键的致病因子包括Monilinia fructigena,Monilinia laxa和Monilinia fructicola,需要详细了解它们的遗传构成以进行有效的管理.

研究的目的:

为了评估Monilinia spp.的遗传多样性. 使用放大片段长度多态 (AFLP).
分析86种莫尼利尼亚种类的遗传变异性. 从韩国主要的石头水果地区分离出来的菌株.
为了将遗传模式与地理来源,宿主植物和杀菌剂敏感性相关联.

主要方法:

隔离了86种Monilinia spp. 这种植物. 来自韩国五个省份的菌株.
扩大碎片长度多态 (AFLP) 的应用,用于基因分析的20个原始对.
遗传学分类,主要坐标分析 (PCoA) 和PERMANOVA用于数据分析.

主要成果:

在AFLP的分析中,在Monilinia spp.中发现了三个不同的基因组. 菌株. 菌株. 这些菌株.
来自吉奥拉省的菌株始终形成一个单独的遗传组.
单独的Monilinia fructicola被进一步分为AFLP定义的三个组,与地理来源和宿主植物相关的显著模式.

结论:

在研究棕色腐烂病原体的遗传变异性方面,AFLP是有效的,比如Monilinia fructicola.
地理来源和宿主植物是影响莫尼利尼亚种群遗传结构的重要因素.
对病原体遗传变异的持续监测和管理对于控制棕色腐烂病至关重要.

Mutation, Gene Flow, and Genetic Drift

Mutation, Gene Flow, and Genetic Drift

In a population that is not at Hardy-Weinberg equilibrium, the frequency of alleles changes over time. Therefore, any deviations from the five conditions of Hardy-Weinberg equilibrium can alter the genetic variation of a given population. Conditions that change the genetic variability of a population include mutations, natural selection, non-random mating, gene flow, and genetic drift (small population size).
