Single-Leaf Resolution of the Temporal Population Dynamics of Aureobasidium pullulans on Apple Leaves

Abstract: The abundance of phylloplane microorganisms typically varies over several orders of magnitude among leaves sampled concurrently. Because the methods traditionally used to sample leaves are destructive, it has remained unclear whether this high variability is due to fixed differences in habitat quality among leaves or to asynchronous temporal variation in the microbial population density on individual leaves. We developed a novel semidestructive assay to repeatedly sample the same apple leaves from orchard tree… Show more

“…We showed previously that Ap populations typically vary from 10-to 100-fold among apple leaves (Woody et al 2003), analogous to epiphytic bacterial populations (Hirano et al 1982). First, what is the basis for variation in microbial population densities among leaves?…”

“…The habitat of A. pullulans is quite broad; it has been isolated from different substrates and samples (bark, roots, marine sediments, waters). This "black yeast" is from an ecological point of view the ubiquitous species, found mainly on the phylloplane (Inácio et al 2002, Woody et al 2003. A. pullulans was the dominant species of water samples taken in autumn from the fish-pond (situated also in the forest park Železná Studnička) (Sláviková and Vadkertiová 1995) and artificial lake waters (located in the Lowland of Záhorie) (Sláviková and Vadkertiová 1992) when the water contained many fallen leaves.…”

“…This work further demonstrates the advantages of being able to repeatedly sample the same leaves over time (31), thereby uncovering potentially subtle leaf-specific changes that otherwise would be obscured in experimental noise. Similar patterns tended to develop among individual leaves, with densities becoming significantly higher on veinal sites than on interveinal sites.…”
