EXPERIMENT INFORMATION

Effect of Spaceflight on Microbial Gene Expression in Saccharomyces cerevisiae (Yeast GAP 1) (CGBA04CN 1_2)
Principal Investigator
Research Area:
Microbiology
Species Studied
Scientific Name: Saccharomyces cerevisiae Species: Yeast, brewer's
Study Type

Description
OBJECTIVES:
The objective of this experiment is to identify the S. cerevisiae genes that provide a selective advantage or disadvantage for cell survival in the space environment. The genes which convey a survival advantage and those that determine a survival disadvantage in response to spaceflight will be identified by whole genome microarray-mediated fitness expression profiling of diploid homozygous and heterozygous S. cerevisiae cultures. The results will be compared to those obtained when the same experiments are performed, with the identical microbes cultured under ground-based conditions of modeled microgravity.
