Elicitins are a family of structurally related proteins that induce hypersensitive response in specific plant species. Two Phytophthora infestans cDNAs, inf2A and inf2B, potentially encoding novel elicitin-like proteins, were isolated from a cDNA library made from infected potato tissue. Multiple sequence alignments and phylogenetic analyses of 19 elicitins and elicitin-like proteins from nine Phytophthora spp. and from Pythium vexans suggest that there are at least five distinct classes within the elicitin family.
激发素是一类结构相关的蛋白质家族，可在特定植物物种中诱导超敏反应。从受感染马铃薯组织构建的cDNA文库中分离出两个致病疫霉cDNA，即inf2A和inf2B，它们可能编码新型激发素样蛋白。对来自9种疫霉属物种和瓜果腐霉菌的19种激发素和激发素样蛋白进行的多序列比对和系统发育分析表明，激发素家族中至少存在五个不同的类别。
