Identification of indole-3-acetic acid in Pichia spartinae, an ascosporogenous yeast from Spartina alterniflora marshland environments

The ascosporogenous yeast Pichia spartinae Ahearn, Yarrow & Meyers (1970) is the predominant yeast occurring on plant rhizoid and root surfaces and within the culm vascular spaces of cordgrass, Spartina alterniflora Loisel., in the Barataria Bay marsh region of Louisiana, and in other saline and...

Description
Summary:The ascosporogenous yeast Pichia spartinae Ahearn, Yarrow & Meyers (1970) is the predominant yeast occurring on plant rhizoid and root surfaces and within the culm vascular spaces of cordgrass, Spartina alterniflora Loisel., in the Barataria Bay marsh region of Louisiana, and in other saline and oligohaline marsh environments where this plant forms the basis of estuarine productivity. Unispecific concentrations of P. spartinae as great as 9 x 10 super(-6) colony forming units/g live plant tissue have been found in culm vascular spaces of S. alterniflora . It has been postulated that indole-3-acetic acid (IAA) produced by ectomycorrhizal and endomycorrhizal fungi may serve a functional role in symbiotic relationships with their host plants. In the present study, we have attempted to document the occurrence of IAA in P. spartinae as an initial step in examination of the action of auxin(s) in this noteworthy yeast/host plant association.
