2007 Research Project: Expression patterns in Arabidopsis treated with non-freezing cold temperature

Sudden freezing temperatures are lethal to Arabidopsis plants. However, when plants are first exposed to a non-freezing low temperature, they develop a tolerance to subsequent freezing temperatures. This process, which is called cold acclimation, is reported to be conserved in other plants, including crop plants.

What are the changes in gene expression that accompany this process?
We will observe changes in gene expression in Arabidopsis plants that were treated with non-freezing cold temperature compared to unstimulated plants.
Could we use this knowledge to create transgenic plants or revise standard growth practices that would increase cold tolerance in important crop plants?

The microarrays contain 29,000 70-mer oligonucleotide elements for Arabidopsis thaliana; these slides were produced at the
University of Arizona. More information about the slides, including description of the gene loci, can be found at Platform GPL4570.
