PCR Detection of N.coenophialum and N.lolii / 微生物学通报

ABSTRACT

18 fungal strains including N.coenophialum,N.lolii, N.huerfanum、N.chisosum、N.aotearoae、N.sp.and 8 varieties of grass seeds belonging to Festuca arundinacea and Lolium perenne have been studied.With amplification of IS1～IS3 and F1～R1 of genomic DNA, the primers Tub-2-F～Tub-2-R from Tubulin-2 gene and F3～R3 from NC25 gene have been designed.A PCR method to detect N.coenophialum and N.lolii was established, and also a nested-PCR method to detect N.coenophialum and N.lolii in single seed was established.These PCR detection methods are strongly special and much credible and rapid-speeded.
