概括

果树脂道变色 (RCD) 与特定的细菌有关,而不是真菌. 这项研究使用下一代测序来识别受影响和健康的果中的细菌和真菌群体,揭示了塔图梅拉和潘托亚是主要的罪祸首.

科学领域:

植物病理学植物病理学
微生物学微生物学
果实科学果实科学

背景情况:

树脂通道变色 (RCD) 对果果质量,消费者信任和市场价值产生负面影响.
负责果中RCD的精确生物病原体仍然未被确定.
了解与RCD相关的微生物群落对于开发管理策略至关重要.

研究的目的:

与健康水果相比,研究受RCD影响的果果的微生物社区组成.
通过下一代测序来识别可能导致RCD的细菌和真菌病原体.
在RCD的病因学中区分细菌和真菌生物的作用.

主要方法:

下一代测序针对细菌群体的16S rRNA基因和真菌群体的内部转录间隔器 (ITS) 区域.
在RCD受影响和健康果之间对微生物多样性概况的比较分析.
生物信息分析以确定每个样本组中占主导地位的细菌和真菌种类.

主要成果:

健康果中的细菌群体与受RCD影响的水果中的细菌群体是不同的,并且分别聚集.
在受RCD影响的果中,Tatumella和Pantoea物种的数量显著增加,它们是已知的植物病原体.
菌群体在健康和受RCD影响的水果之间变化较小,Meyerozyma和Naganishia等酵母主导RCD+样本.

结论:

细菌病原体,特别是Tatumella和Pantoea物种,被强烈认为是果中RCD的主要原因.
的存在,主要是酵母,似乎与RCD的发展不太直接相关.
这些发现为果生产中针对RCD引起的细菌的有针对性的隔离和控制策略铺平了道路.

Fungal Group Zygomycota

Fungal Group Zygomycota

Zygomycota, previously classified as a distinct fungal group, are primarily terrestrial, saprophytic molds that play a crucial role as decomposers. Recent phylogenetic studies have revealed that these fungi are now divided into two major clades — Mucoromycota, which includes many symbiotic species, and Zoopagomycota, which primarily consists of parasitic and pathogenic fungi. These groups exhibit distinct ecological roles and reproductive strategies while sharing key structural and...
