A Genetic Analysis of Differences in Optimal and Maximal Growth Temperatures among Mesophilic and Thermophilic Members of the Sordariales.

Understanding the genetics of temperature responses in filamentous fungi has important implications for ecology, cell biology and industry.  We are comparing optimal and maximal growth temperatures for strains from varying latitudes and elevations in an attempt to identify candidate strains for genetic analysis.  We are employing the mesophile Neurospora discreta and the thermophile Myceliopthera heterothallica, both members of the Sordariales with fully sequenced genomes.  Race-tube experiments show differences between the optimal growth temperatures (OGT) of N. discreta strains from New Mexico and Alaska, as well as M. heterothallica strains from Germany and Indiana.  We are now determining whether differences in OGT segregate among progeny from crosses of these strains, toward the goal of using genomic approaches to identify the genes responsible.
