从有机或常规管理措施收获的苹果中的真菌多样性进行了分析，在不同的水果位置（茎端，萼端，果皮，和受伤的肉）后不久，水果购买（T1）和2周后的存储（T5）。总共回收了5，760，162个高质量的真菌序列，并分配到8，504个操作分类单位。子囊菌门的成员在所有样品中占优势，占检测序列总数的91.6%。其次是担子菌门（8%）、壶菌门（0.1%）和未鉴定的真菌（0.3%）。α和β多样性分析显示，存在显着不同的真菌种群在调查的水果部分。在检测到的真菌中，青霉属在果皮和受伤的肉中占优势，而链格孢属。在包括苹果果心组织的花萼和茎端样品中普遍存在。几个分类单位，似乎是密切相关的致病真菌与继发性人类感染的果皮和伤口。此外，显着不同的人口揭示了有机和传统的苹果，这一结果是一致的，在所有调查的水果部分（萼端，果皮，茎端，受伤的肉）。几个独特的类群，专门检测有机苹果表明，管理措施可能是一个促成因素，在确定的类群。相比之下，在两个评估时间（T1和T5）中显示出很小的差异。本研究的结果代表了目前的知识在苹果果实组织中的真菌微生物群的进步。
The fungal diversity in harvested apples from organic or conventional management practices was analyzed in different fruit locations (stem end, calyx end, peel, and wounded flesh) shortly after fruit purchase (T1) and after 2 weeks of storage (T5). A total of 5,760,162 high-quality fungal sequences were recovered and assigned to 8,504 Operational Taxonomic Units. Members of the phylum Ascomycota were dominant in all samples and accounted for 91.6% of the total number of detected sequences. This was followed by Basidiomycota (8%), Chytridiomycota (0.1%), and unidentified fungi (0.3%). Alpha and beta diversity analyses revealed the presence of significantly different fungal populations in the investigated fruit parts. Among detected fungi, the genus Penicillium prevailed in the peel and in the wounded flesh while Alternaria spp. prevailed in the calyx and stem end samples that included apple core tissues. Several taxonomic units that appear to be closely related to pathogenic fungi associated with secondary human infections were present in peel and wounds. Moreover, significantly different populations were revealed in organic and conventional apples and this result was consistent in all investigated fruit parts (calyx end, peel, stem end, and wounded flesh). Several unique taxa were exclusively detected in organic apples suggesting that management practices may have been a contributing factor in determining the taxa present. In contrast, little differences were revealed in the two assessment times (T1 and T5). Results of the present study represent an advancement of the current knowledge on the fungal microbiota in collected fruit tissues of apple.
