植物叶圈内的微生物群落能够影响宿主的适应性和生长，包括宿主对植物病原菌的抵抗力。叶圈内细菌和真菌内生菌的聚集与多种因素有关，包括宿主遗传和环境。在这项工作中，在感染真菌病原体Neonectria ditissima的苹果树的全同胞家族中研究了宿主遗传学在植物微生物组组装中的作用。数量性状基因座（QTL）分析显示，存在影响单个内生菌分类群的丰度的多个基因座，其中大多数QTL对内生菌丰度具有中等至大的影响（20-40%）。LG 1、3、4、5、10、12、13、14和15上的QTL区域显示影响多个分类群。只有一小部分的总体分类组成的变化受宿主基因型的影响，与主成分的显着QTL命中解释细菌和真菌组成的总方差的<8%和<7.4%，分别。四个确定的QTL共定位与以前确定的地区与耐新丛赤霉ditissima。这些结果表明，有一个遗传基础，塑造苹果内生菌的组成和苹果中的微生物-宿主协会可以通过育种定制。
The plant phyllosphere is colonized by microbial communities that can influence the fitness and growth of their host, including the host’s resilience to plant pathogens.There are multiple factors involved in shaping the assemblages of bacterial and fungal endophytes within the phyllosphere, including host genetics and environment. In this work, the role of host genetics in plant-microbiome assembly was studied in a full-sibling family of apple (Malus x domestica) trees infected with the fungal pathogen Neonectria ditissima. A Quantitative Trait Loci (QTL) analysis showed that there are multiple loci which influence the abundance of individual endophytic taxa, with the majority of QTL having a moderate to large effect (20-40%) on endophyte abundance. QTL regions on LG 1, 3, 4, 5, 10, 12, 13, 14 and 15 were shown to affect multiple taxa. Only a small proportion of the variation in overall taxonomic composition was affected by host genotype, with significant QTL hits for principal components explaining <8% and <7.4% of the total variance in bacterial and fungal composition, respectively. Four of the identified QTL colocalised with previously identified regions associated with tolerance to Neonectria ditissima. These results suggest that there is a genetic basis shaping apple endophyte composition and that microbe-host associations in apple could be tailored through breeding.
