  甘薯褪绿矮化病毒(Sweet potato chlorotic stunt virus,SPCSV)和甘薯羽状斑驳病毒(Sweet potato feathery mottle virus,SPFMV)协生共侵染甘薯可引起甘薯病毒病害(Sweet potato virus diseases,SPVD).感染SPVD的甘薯表现植株矮化,叶片褪绿、畸形等症状.SPVD对甘薯产量影响极大,严重时可造成90%以上的产量损失,甚至绝收,是甘薯上的毁灭性病害.目前我国的主要甘薯产区均已发现SPVD.

苹果树腐烂病(Valsa ceratosperma)可造成果树主干及整树死亡,甚至毁园。自1916年腐烂病在辽宁省南部地区发现以来,该病在我国已有过几次大流行,造成了严重的经济损失。由于对于苹果树腐烂病菌的侵染、致病过程与机理尚不清楚,制约了对该病害发生、流行规律的深入了解,导致病害防治工作低效、盲目和被动,腐烂病的为害近年来仍在逐年加重。随着生物技术和分子生物学的不断发展,利用分子标记如绿色荧光
欧美杨新型溃疡病是近年欧美杨上新发生的溃疡病.2005年5月,该病害是在河南省濮阳市清丰县6年生107杨树上首次被发现,其症状是发病初期流出大量酸臭的汁液,随后树皮开裂、韧皮部局部坏死、坏死处组织肿胀的症状,病斑长可达1 ~2m.目前,该病害已经在我国河南北部、山东西部大面积局部发生和危害,天津市也有分布.
