Pyrrolizidine alkaloid accumulation in tall fescue during plant growth and development

摘要：

Tall fescue, Lolium arundinaceum ( Schreb.) Darbyshire, infected with the endophytic fungus, Neoty phodium coenophialum (Morgan‐Jones and Gams) Glenn, Bacon, and Hanlin, accumulates peramine, ergot and loline alkaloids.The loline alkaloids are present in much greater amounts than the other alkaloids.In the common endophyte strain the predominant pyrrolizidine alkaloids are N‐formylloline ( NFL) and N‐acetylloline ( NAL).Accumulation of these alkaloids is a significant determinant for ecological fitness.The objectives of this study were to determine development of N.coenophialum in tall fescue and the accumulation of NAL and NFL in different plant tissues and clippings.
