Phytotoxic metabolites produced in liquid culture by six species of Lasiodiplodia isolated in Brazil and causing Botryosphaeria dieback of grapevine were chemically identified. As ascertained by LC/MS, L. brasiliense, L. crassispora, L. jatrophicola, and L. pseudotheobromae produced jasmonic acid, and L. brasiliense synthesized, besides jasmonic acid, also (3R,4S)-4-hydroxymellein. L. euphorbicola and L. hormozganensis produced some low molecular weight lipophilic toxins. Specifically, L. euphorbicola produced (-)-mellein, (3R,4R)-(-)- and (3R,4S)-(-)-4-hydroxymellein, and tyrosol, and L. hormozganensis synthesized tyrosol and p-hydroxybenzoic acid. This is the first report on the production of the above cited metabolites from L. euphorbicola and L. hormozganensis. The phytotoxic activity of the metabolites produced is also discussed and related to the symptoms these pathogens cause in the grapevine host plants.
对在巴西分离得到的六种引起葡萄藤葡萄座腔菌属溃疡病的葡萄座腔菌在液体培养中产生的植物毒性代谢产物进行了化学鉴定。通过液相色谱/质谱法确定，巴西葡萄座腔菌、厚孢葡萄座腔菌、麻疯树葡萄座腔菌和拟可可葡萄座腔菌产生茉莉酸，并且除茉莉酸外，巴西葡萄座腔菌还合成了(3R,4S)-4-羟基间苯二酚。大戟葡萄座腔菌和霍尔木兹葡萄座腔菌产生一些低分子量的亲脂性毒素。具体而言，大戟葡萄座腔菌产生(-)-间苯二酚、(3R,4R)-(-)-和(3R,4S)-(-)-4-羟基间苯二酚以及酪醇，霍尔木兹葡萄座腔菌合成酪醇和对羟基苯甲酸。这是关于大戟葡萄座腔菌和霍尔木兹葡萄座腔菌产生上述代谢产物的首次报道。还讨论了所产生代谢产物的植物毒性活性，并将其与这些病原体在葡萄藤寄主植物中引起的症状相关联。
