摘要
本文以单子叶植物小麦（ＴｒｉｔｉｃｕｍａｅｓｔｉｖｕｍＬ．）的黄化苗为材料，用小麦品种ＳＷ８９－２５８９的多聚半乳糖醛酸酶抑制蛋白（ＰＧＩＰ）作用４种病原真菌，发现小麦ＰＧＩＰ对几种病原真菌分泌的内切多聚半乳糖醛酸酶（ｅｎｄｏ－ＰＧ）有抑制作用，４种病原真菌ｅｎｄｏ－ＰＧ被抑制程度的大小关系依次为Ｐｙｒｉ－ａｃｌａｒｉａｏｒｙｚａｅ、Ｓｃｌｅｒｏｔｉｎｉａｓｃｌｅｒｏｔｉｏｒｉｕｍ、Ｆｕｓａｒｉｕｍｇｒａｍｉｎｅａｒｕｍ、Ｅｘｓｅｒｏｈｉｌｕｍｔｕｒｃｉｃｕｍ；小麦ＰＧＩＰ对４种病原真菌生长有抑制作用，并且能引起小麦禾谷镰刀菌和玉米大斑病菌生长异常。
Polygalacturonase inhibiting protein (PGIP) purified from wheat ( Triticum aestivum L.)yellow seedling was initiated to directly effect four fungi: Fusarium graminearum Schw., Exserohilum turcicum Leonarddsuggs, Pyricularia oryzae CaV.and Sclerotinia sclerotiorium (Lib) de Bary.The endo PGs from four kinds of fungi were inhibited by PGIP and their growth was delayed by PGIP,furthermore PGIP caused the abnormal growth of F.graminearum and E.turcicum .
