臺灣感染馬蹄金之白絹病菌

Athelia rolfsii infects dichondra in Taiwan

2018年五月，在臺灣彰化縣大村的Dichondra donelliana馬蹄金植株上發現菌絲及菌核，分離得白絹病菌，藉形態與分子特徵鑑定該菌為Athelia rolfsii。病原性測試於D. donelliana、D. repens上進行，已由柯霍式法則完成病原性測試，且植物之鑑定由ITS、rbcL、matK序列支持。就我們所知，本研究為世界上首次紀錄D. donelliana為A. rolfsii之寄主植物。

"In May 2018, mycelia and sclerotia were discovered on blighted Dichondra donelliana plants at Dacun, Changhua County, Taiwan. A southern blight fungus was isolated and identified as Athelia rolfsii based on the morphological and molecular characteristics. Koch's postulates were fulfilled by pathogenicity tests conducted on D. donelliana and D. repens and the identification of the plants was supported by the ITS, rbcL, and matK sequences. To our knowledge, this is the first record of D. donelliana as a host of A. rolfsii worldwide."
