Abstract

When A' and A2 isolates of Phytophthora Parasitica were grown on medium containing chlor-oneb orethazol, both isolates produced oospores in sectors. Single-zoospore cultures obtained from the oospore sectors consisted of both A1 and A2 mating types, while those obtained from non-treated cul-tures consisted of only the parental mating type. When A1 and A2 isolates of P.cinnamomi were grown on medium containing chloroneb or ethazol, only A1 produced oospores in sectors. Single-chlamydospore cultures obtained from the sectors consisted of both A1 and A2 types. The A2 sexual variants also gave rise to A1 type of single-chiamydospore cultures after treatment withe thazol, in-dicating the reversible nature of mating type change. Both hormone production and reception were changed when A1 mating type of P．cinnamomi was changed from A1 to A2, and vice versa. 將P.parasitica的A1和A2菌株培養於含有chforoneb或ethazol的培養基，兩配對型的菌株均在培養基產生局部卵孢子區。自這些卵孢子區分離的單游走子菌株含有A1和A2配對型，然而分離自無處理菌落的單游走子菌株只含有與母菌株相同的配對型。將P.cinnamomi的A1和A2菌株培養於含有chioroneb或ethazol的培養基，只有A1菌株形成局部卵孢子區。自這些卵孢子區分離的單厚膜孢子菌株含有A1和A2配對型。當A2性變異株經ethazol處理後，自其分離之單厚膜孢子菌株中也出現A2配對型。此結果顯示兩配對型可以互相轉變。當P. cinnamomi的配對型自A1轉變成A2時，賀爾蒙的形成與接受也同時改變，反之亦然。
