A Method for the Specific Detection of Phomopsis destruens in Sweet Potato by PCR

Abstract

Foot rot caused by Phomopsis destruens (Harter) Boerema is a major concern for sweet potato production in Taiwan. The conventional methods for the identification of P. destruens are based on culture isolation and morphological analyses, but they are time-consuming and often inconclusive. 甘藷基腐病 (foot rot) 是由Phomopsis destruens 所引起，為近年來台灣甘藷生產的主要限制因子之一。目前P. destruens 之鑑定仍依賴傳統方法，以病原菌之組織分離及形態特徵為主，不但耗時費力且成功分離出病原菌之比率不高。
