摘要(Abstract)：

隐真菌门(Cryptomycota)是最近才建立的、隶属于真菌界的一个新的门。本文简要回顾了隐真菌门的来历及建立的依据,介绍了隐真菌的研究进展。系统进化分析显示,隐真菌位于真菌进化树的基部;依据已有的分子序列估计其种类非常丰富,在土壤、海洋与淡水环境中广泛分布。隐真菌细胞壁无几丁质,但其基因组中存在具有肌球蛋白结构域的II型几丁质合成酶基因;生活史相对简单,包括游动孢子、孢囊与孢子囊等阶段;通常在壶菌等真菌细胞内寄生,可通过吞噬作用吸收营养。由于壶菌可侵染浮游植物,因此推测隐真菌可能在水体初级生产及碎屑食物网中发挥调节作用。最后,对有关隐真菌的分子系统、分离与培养、基因组、多样性及分子生态学研究进行展望。
