Title	An oat species lacking avenacin is susceptible to infection by Gaeumannomyces graminis var. tritici
Journal	Physiology and Molecular Plant Pathology
Year	1994
Volume	45
Pages	457-467
Author	Osbourn A Clarke B Lunness P Scott P Daniels M
Abstract	The saponin avenacin is a pre-formed inhibitor of fungal growth and occurs in the roots of Avena species Gaeumannomyses graminis var tritici (the causal agent of take-all disease of wheat) is unable to attack oats, apparently because of the sensitivity of this fungus to avenacin After screening a wide range of oat genotypes, one species, Avena longiglumis, was identified which lacked detectable levels of avenacin and was susceptible to infection by G. graminis var. tritici, supporting a role for avenacin as a determinant of resistance to fungal attack.
