概括

人们经常错误地认为Fusarium poae会产生T-2/HT-2毒素. 这项研究没有发现F. poae产生T-2/HT-2毒素的证据,反驳了之前的概括.

科学领域:

菌群学菌群学菌群学是指菌群学
植物病理学植物病理学
食品安全食品安全

背景情况:

菌头部病 (Fusarium head blight,FHB) 是一种重要的谷物作物疾病.
在FHB调查中经常检测到Fusarium poae,并且可以产生真菌毒素.
之前的文献经常基于有限的证据将F. poae概括为T-2/HT-2毒素生产者.

研究的目的:

通过实验验证或反驳Fusarium poae.所报告的T-2/HT-2毒素的产生.
调查F. poae.中T-2/HT-2毒素产生的遗传基础.

主要方法:

获取和原先识别的F. poae菌株的遗传学确认.
对F. poae菌株进行菌培养,以评估菌毒素的产量.
全基因组测序和生物信息分析以确定关键的产生毒素的基因 (TRI16).

主要成果:

获得的F. poae菌株被遗传学证实.
从F. poae.的基培养中没有检测到T-2/HT-2毒素的产生.
在F. poae基因组中没有发现TRI16基因的正基因,这对于T-2毒素合成至关重要.

结论:

虫 (Fusarium poae) 似乎不会产生T-2/HT-2毒素.
在科学文献中将F. poae作为T-2/HT-2生产者的概括是毫无根据的.
这一发现对FHB管理和食品安全评估有影响.

关键词:

类头部病类头部病类 (Fusarium poae) 是一种植物.这是一种T-2毒素.代谢生物组的代谢生物组菌类毒素 (mycotoxins) 是一种有毒的物质.在Tricho的场景里.

Transgenic Plants

Transgenic Plants

Recombinant DNA technology called transgenesis is often used to add a foreign gene or remove a detrimental gene from an organism. Such genetically modified organisms are called transgenic organisms.
The first-ever transgenic plant was a tobacco plant developed in 1983 that showed resistance against the tobacco mosaic virus. Since then, many transgenic plants have been developed and commercialized for improving the agricultural, ornamental, and horticultural value of a crop plant. Transgenic...
