概括

像DON和ENN B这样的Fusarium菌毒素经常在小麦,大麦和三角中发现. 特里托德表现出敏感性,引发了对料安全和动物健康的担忧.

科学领域:

农业科学农业科学
食品安全食品安全
植物病理学植物病理学

背景情况:

虫菌毒素对料安全和动物健康构成风险.
无症状的植物可以含有多种Fusarium真菌毒素.
气候变化影响了农作物中菌毒素的发生.

研究的目的:

在无症状的小麦,大麦和三角中调查多种Fusarium菌毒素的存在和水平.
为了比较作物类型和植物部位 (草与核) 之间的真菌毒素污染.
评估真菌毒素污染的跨年变化.

主要方法:

使用UHPLC-MS/MS进行脱氧烯 (DON),3-AcDON,15-AcDON,T-2,HT-2,ZEN,ENN B和DON3Glc的量化.
从两个收获年 (2020年,2021年) 分析了32种小麦,大麦和三角.
核和吸管中的真菌毒素水平的比较.

主要成果:

DON和ENN B是最频繁检测到的真菌毒素,每年有显著的变化.
样品通常含有比核更高的真菌毒素水平.
平均而言,Tritordeum的DON污染率最高,而大麦的污染率最低. 在和大麦的谷粒和草中,ENN B的含量是可比的.
在一些tritordeum样本中检测到T-2和HT-2毒素;ZEN主要在2020年的草中发现.

结论:

在无症状的谷物作物中存在多种Fusarium菌毒素,对料安全构成风险.
三角对真菌毒素污染具有敏感性,需要监测和育种策略.
气候条件显著影响菌毒素的流行,突出了适应性管理实践的需要.

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...
