摘要:
开发了一种基于PCR的草莓炭疽病致病菌暹罗炭疽菌(Colletotrichum sisamense)检测方法。通过分析暹罗炭疽菌及24种真菌的ITS区序列,设计了1条反向特异引物CsiaR,结合引物CgInt可仅从暹罗炭疽菌中扩出约 400 bp 片段。对不同浓度暹罗炭疽菌DNA溶液进行检测,第1轮和第2轮PCR的最低检出限分别为50 pg/μL和 5 fg/μL;对接种不同浓度暹罗炭疽菌分生孢子悬浮液的草莓样本(接种48 h,症状未出现)进行检测,低于1.0×104个孢子/mL的处理无法检出;对田间随机采集的草莓样本检测时,PCR检测阳性的样本(含有症状和无症状)中均可分离到暹罗炭疽菌。总体来说,本方法可用于草莓中暹罗炭疽菌的早期、快速及准确检测,从而为草莓炭疽病的及时有效防控提供依据。
