The Third Naturally Occurring Attractant toward Zoospores of Phytopathogenic Aphanomyces cochlioides from the Spinacia oleracea Host Plant
摘要:
通过对菠菜叶成分的生物测定调查,5,4'-二羟基-3,3'-二甲氧基-6,7-亚甲二氧基黄酮被确定为寄主植物中第三种天然存在的吸引其病原体鹅膏蕈蚊子孢子的物质。该分离物在涂有 10-5 M 溶液的 Chromosorb W AW 粒子(60-80 目)周围显示出吸引孢子悬浮液的活性。不过,这种活性比菠菜根部的吸引剂嗜蜗牛蛋白 A 的活性低 1/100-1/1000。用本分离物和相关化合物进行的生物测定表明,5,3',4'-三羟基-3-甲氧基-6,7-亚甲二氧基黄酮不具有引诱活性,而是对菠菜中的前两种引诱剂具有微弱的拮抗活性。
