自然界中千奇百怪的菌类

我们为读者所呈现的这些千奇百怪的菌类植物,严格意义上说应当属于菌类植物的真菌门。多数种类营养体的构造为分枝或不分枝的丝状体,每一条丝称为菌丝(Hypha),组成一个植物体所有的菌丝称为菌丝体(Mycelium)。高级的种类菌丝体在有性繁殖时形成各种子实体,如常见的银耳、菌灵芝、蘑菇等都是子实体。真菌的细胞壁大多由几丁质构成,细胞内常有多个细胞核,不含叶绿素,寄生或腐生或兼营寄生和腐生生活。贮藏物质以肝糖为主,也常含有油脂,但不含淀粉。药用植物较多。     

Active changes of lignification-related enzymes in pepper response to Glomus intraradices and/or Phytophthora capsici

INTRODUCTION Plants have defense mechanisms against patho-gen infection by inducing systemic resistance in re-sponse to localized pretreatment with biological cotrol agents, thus making them resistant to subsequpathogen infection (Caruso et al., 1999; Hammschmidt, 1999; Mohammadi and Kazemi, 2002; yada et al., 1995; Pozo et al., 2002; Ray et al., 199Biological control of plant pathogens has receivmuch more attention.
