Ergot Alkaloid Contents in Hybrid Rye are Reduced by Breeding

چکیده

Contamination by ergot caused the phytopathogenic fungus Claviceps purpurea is a constant threat to whole rye value chain. Ergot alkaloids (EA) produced within fungal sclerotia are toxic for humans and animals subjected strict regulations in human food. Our main objective was analyze whether less susceptible cultivars with lower content of also contain fewer (EA). We analyzed 15 factorial single crosses multi-environmental trials artificial inoculation their severity, twelve EAs HPLC, total ELISA. The genotypes displayed wide range pollen shedding from fully sterile fertile, severity expressed as percentage relative harvest (0.22–11.47%), EA contents when HPLC (0.57–45.27 mg/kg. Entry-mean heritabilities were high throughout (0.87–0.98). analysis yielded preponderance male general combining ability (GCA) variances, estimates females smaller, although significant. measured ELISA were, on average, seven times larger. correlation between determined r = 0.98 (p ≤ 0.01) only somewhat In conclusion, prone support contents.

Über den Gehalt von Mutterkorn an toxischen Alkaloiden sowie der Beziehung zwischen der Mutterkombelastung des Roggens und dem Alkaloidgehalt des Mutterkorns

In the last decades, data on the content of toxic alkaloids in ergot and the relationship of the ergot contamination in rye and the alkaloid content in ergot has been scarce. Therefore, the level of ergot contamination (g/kg rye) and the alkaloid contents (mg/kg ergot) of ergot grown on 7, 21 and 24 artificially infected rye varieties at three German locations in 2002, 2003 and 2004 were determ...

Ergot of Rye as an Oxytocic

tioners were frequently in the habit of giving it to hasten tedious labour that was occasioned solely by the presence of some mechanical obstacle. In this way they invoked and called to their aid the powers, as Dr. Barnes has remarked, of a Frankenstein, quite beyond their control, whose unbridled strength might give rise to frightful disasters; in their ignorance they quite forgot that the pro...

Progress and prospects in ergot alkaloid research.

Ergot alkaloids, produced by the plant parasitic fungi Claviceps purpurea are important pharmaceuticals. The chemistry, biosynthesis, bioconversions, physiological controls, and biochemistry have been extensively reviewed by earlier authors. We present here the research done on the organic synthesis of the ergot alkaloids during the past two decades. Our aim is to apply this knowledge to the sy...

Ergot alkaloid transport across ruminant gastric tissues.

Ergot alkaloids cause fescue toxicosis when livestock graze endophyte-infected tall fescue. It is generally accepted that ergovaline is the toxic component of endophyte-infected tall fescue, but there is no direct evidence to support this hypothesis. The objective of this study was to examine relative and potential transport of ergoline and ergopeptine alkaloids across isolated gastric tissues ...
