Abstract
稻熱病是全世界水稻栽培的最主要病害之一。稻熱病菌常因與寄主間互動而導致的共同演化，使得生理小種複雜多變，特別是水稻育種多以直式抗病為主要選育目標，故水稻品種往往在大面積推廣數年後，因新的生理小種出現而造成嚴重的流行病。近年來，應用分子標誌所獲得的遺傳譜系，適時提供了輔助分析稻熱病菌族群遺傳結構的重要資訊。目前研究稻熱病菌族群遺傳的主要分子標誌包括MGR586、MAGGY、Pot2及SSR等，藉由這些分子標誌所獲得之DNA指紋圖譜分析結果，使得稻熱病菌族群遺傳之研究得以迅速進展。本文主要回顧分子標誌應用於稻熱病菌族群遺傳研究上的進展，並討論未來防治稻熱病的策略。
Rice blast is one of the most devastating diseases of cultivated rice worldwide. Rice blast fungus Magnaporthe oryzae could evolve many physiological races in nature as a result of coevolution with rice hosts. Since rice cultivars were usually bred based on vertical resistance, so serious epidemic of rice blast often occurred due to newly evolved races after new breeding cultivars were cultivated. During past two decades, molecular markers, including MGR586, MAGGY, Pot2, and SSR, were developed and used to analyzed genetic structure of Magnaporthe oryzae population in nature. The present paper will review the progress on the application of molecular markers and discuss the prospects of strategies for management of rice blast disease.
