Genomic basis of the ecological success of nectar yeasts in their carbon-stressed and nitrogen-limited environments

ABSTRACT: The goal of the research is to identify the physiological pathways that influence survival, growth, and competitive ability of the species of yeast that colonize floral nectar. Initially sterile, floral nectar is colonized by multiple species of microbes via insects and birds that visit the flowers for nectar. Once colonized, the microbes face two major challenges of the nectar environment: high osmotic pressure, caused by excessive carbon supply, and strong resource competition, caused by low nitrogen availability. We propose to study the genetic basis of the unique ecological strategies that allow nectar yeasts to cope with these challenges, and to determine the effects that these genes may have on microbe microbe interactions in nectar and the chemical properties of nectar that affect pollinator preference. The work (proposal:https://doi.org/10.46936/10.25585/60001130) conducted by the U.S. Department of Energy Joint Genome Institute (https://ror.org/04xm1d337), a DOE Office of Science User Facility, is supported by the Office of Science of the U.S. Department of Energy operated under Contract No. DE-AC02-05CH11231.
