慈姑黑粉病病原菌名称的演变

摘要

慈姑黑粉病是慈姑生产中最重要的病害之一.病原菌最初被认为是慈姑实球黑粉菌.随着属名的变化,该病原菌被转移到虚球黑粉菌属称为慈姑虚球黑粉菌.最新研究表明,该病原菌与侵染可变慈姑的病原菌是同种,是畸形虚球黑粉菌的异名.本文说明了慈姑黑粉病痛原菌名称演变原因以及最新进展,这对准确应用病原菌名称提供了参考依据.%Smut is one of the major diseases in Sagittaria trifolia var.sinensis production.The pathogen was first named as Doassansia horiana,and transferred to the genus Doassansiopsis as Doassansiopsis horiana with the change of the genus name.However,the latest studies showed that the pathogen on S.trifolia var.sinensis is the same species as that on Sagittaria variabilis.D.horiana is the synonym of D.deformans.This paper illuminates the reason for name change of the pathogen infecting S.trifolia var.sinensis and its recent research advance,providing a reference basis for applying correct pathogen name.
