Project description:The arrays in this series correspond to a comparative genomic analysis between S. cerevisiae strain JAY270 and the reference laboratory strain S288c. JAY270 is a heterothalic diploid used in bioethanol production from sugar cane feedstock in Brazil. This strain has several chromosomal length polymorphisms between homologous chromosomes. The two Chr6 homologs, Chr6 short and Chr6 long, were examined using microarrays to determine the genomic regions which are rearranged.
