马铃薯专性寄生真菌内生集壶菌的研究进展

内生集壶菌是引起马铃薯癌肿病的一种低等专性寄生真菌。本文首先对国内外马铃薯癌肿病病原菌的分布及危害、生物学特征、致病型及检测、分子生物学研究现状、病害防控等方面的研究进行了综述。针对该病菌是专性寄生真菌,至今仍未见全基因组序列的报道,提出加紧研究不同发生地病原菌的基因组序列,了解基因组序列差异及其与抗病马铃薯品种间的关系的展望,这将有利于推动马铃薯癌肿病抗性基因研究及相关育种工作的开展,为马铃薯癌肿病的发生防患于未然。

Research Progress of Obligate Parasitic Fungus Synchytrium Endobioticum of Potato

Synchytrium endobioticum is a lower obligate parasitic fungus causing potato wart. In this paper, the distribution, harm, biological traits, pathogenicity and determination, current molecular biological studies, disease prevention and control of potato wart in China and abroad are reviewed. Because of no reports so far about the progress of the whole genome sequencing of the potato obligate parasitic fungus, we raise the prospect for stepping up researches on the genome sequencing of the pathogens originated in different places and understanding genome sequence differences and their relationships to disease-resistant potato varieties, which could contribute to the disease-resistant genetic researches on potato wart and to the potato breeding work.
