Molecular understanding of sugar mediated growth control
The overexpression of bZIP11, a transcription factor involved in the response to sugars, inhibits growth of Arabidopsis seedlings (Hanson et al., 2008). A transcriptomic approach has highlighted genes implicated in primary carbon metabolism as direct transcriptional targets of bZIP11 (Ma et al., 2011).

We recently showed that a mutation in these genes results in a partial to total rescue of the bZIP11 overexpression phenotype and therefore hypothesized that other mutations may as well result in the same rescue. To identify these mutants, an EMS mutagenesis has been performed on the bZIP11 overexpressing line suitable for a suppressor screen.

The aims of this project are to screen the M2 population deriving from this mutagenesis and to further characterize the mutants in physiological and molecular methodology.
