摘要

真菌毒素除了降低食物/饲料的质量外，还对人类和牲畜构成巨大威胁。据信，这些毒素是作为真菌防御（应激反应）的一种机制生物合成的。已知对冬季谷物作物最重要的真菌毒素是脱氧雪腐镰刀菌烯醇（DON），这是一种主要由禾谷镰刀菌生物合成的天花粉烯。这份手稿带来了三年（2018年、2019年和2020年）在巴西圣卡塔琳娜西部和南里奥格兰德州西北部进行的实地研究（24个实地实验）的数据，该研究使用了一种红色海藻特有的硫酸多糖卡拉胶，与杀菌剂相结合，有助于抑制脱氧雪腐镰刀菌烯醇（DON）在小麦籽粒中的生物合成和积累。DON污染减少了36.4%。天气条件影响了DON在小麦籽粒中的积累。卡拉胶已被证明是一种生物化合物，无论天气条件如何，都能帮助抑制DON在小麦籽粒中的生物合成和积累。

Deoxynivalenol biosynthesis and accumulation in wheat under application of carrageenan

Mycotoxins pose a large threat to human and livestock besides reducing the quality of food/feed. It is believed that these toxins are biosynthesized as a mechanism of defense (stress-response) of fungi. The most important mycotoxin for winter-cereal crops is known by deoxynivalenol (DON), a trichothecene biosynthesized mainly by Fusarium graminearum. This manuscript brings data of three years (2018, 2019 and 2020) of field research (24 field experiments) in Western Santa Catarina and North-Western Rio Grande do Sul, Brazil using a sulphated polysaccharide exclusive from red seaweed, carrageenan, associated with fungicides to help suppressing deoxynivalenol (DON) biosynthesis and accumulation in wheat kernels. A reduction of 36.4% in DON contamination was observed. Weather conditions have influenced the accumulation of DON in wheat kernels. Carrageenan has shown to be a biological compound capable of helping on the suppression of DON biosynthesis and accumulation in wheat kernels regardless of weather conditions.
