Cloning and analysis of mtDNA probes of Peronophythora litchii
, 2013 利用三種內限制酵素EcoR I 、Hinc II 及(EcoR I + Sac I)剪切荔枝露疫菌PL024菌株之粒線體核酸，將所得核酸片段與pUC 18載體黏合並進行選殖，結果選殖到4個選殖株A2-3、HC3、HC9及ES6，其插入片段大小各為0.6 kb、0.4 kb、0.65 kb及0.6 kb，分別製備為核酸探針。並以墨點漬染法與25株荔枝露疫菌粒線體核酸進行雜合反應，均有雜合交互作用。另以17株Phytophthora菌株及Pythium splendens的全量核酸與核酸探針A2-3、HC3、

CLONING AND ANALYSIS OF MTDNA PROBES OF PERONOPHYTHORA LITCHII (CHEN EX KO ET AL.)
, 2014 荔枝露疫菌 ( Peronophythora litchii Chen ex Ko et al., ) 為台灣 荔枝果樹特有病害 ， 以其孢囊柄類似露菌屬 ( Peronospora ) 及具有 乳突的檸檬狀孢囊，與疫菌屬 ( Phytophthora ) 類似。本研究使用 25個菌株，觀察其無性世代之形態構造； 並於不同溫度培養，以了解溫 度對各菌株菌絲生長之影響，低於 4℃ 及高於 36℃ 各菌株菌絲都不能 生長，生長最適溫為 24℃-28℃。PL024及PL027 菌株在 pH 4時生長較慢 ...

, 2014 荔枝露疫病， 又名霜霉病 ( litchi downy blight )， 由荔枝 露疫菌 (Peronophythora litchii ) 所引起，為荔枝之嚴重病害， 主 要危害近成熟的果實，此病害經由風雨傳播，其發生與氣溫及雨水有密切 關係，持續雨季將致使此病害嚴重發生，因此若能在病害發生前作有效且 快速偵測此病原菌，除有助於防治工作之實施，並能降低本病害在儲運期

, 2014 在疫病菌 (Phytophthora) 屬中，大多數的種 (species) 為病原菌，他們引起主要的糧食作物、蔬菜及水果發生病害，成為生產過程的重要限制因子。有些種為同宗交配型 (homothallic)，單獨培養時可產生卵孢子，有些種為異宗交配型(heterothallic)，必須在同種或不同種間的A1及A2交配型進行配對才會產生卵孢子；然而，有性繁殖過程中所發生的遺傳重組，會使疫病菌創造出新的遺傳變異及新的病原性的個體。芋頭疫病菌 (Phytophthora colocasiae ...

Oospore germination of Peronophythora litchii
, 2011 This germination in the fungus, causing fruit rot of Litchi chinensis, was 30-35% in distilled water but most of the oospores produced short germ tubes which did not develop further. C. 2% produced 1 or 2 sporangia on each germ tube. Sometimes germ tubes
