abstract = {Translation of the transcription factor bZIP11 is repressed
by sucrose in a process that involves a highly conserved
peptide encoded by the 5' leaders of bZIP11 and other plant
basic region leucine zipper (bZip) genes. It is likely that
a specific signaling pathway operating at physiological
sucrose concentrations controls metabolism via a feedback
mechanism. In this paper bZIP11 target processes are
identified using transiently increased nuclear bZIP11 levels
and genome-wide expression analysis. bZIP11 affects the
expression of hundreds of genes with proposed functions in
biochemical pathways and signal transduction. The expression
levels of approximately $80\%$ of the genes tested are not
affected by bZIP11 promoter-mediated overexpression of
bZIP11. This suggests that $<20\%$ of the identified genes
appear to be physiologically relevant targets of bZIP11.
ASPARAGINE SYNTHETASE1 and PROLINE DEHYDROGENASE2 are among
the rapidly activated bZIP11 targets, whose induction is
independent of protein translation. Transient expression
experiments in Arabidopsis protoplasts show that the
bZIP11-dependent activation of the ASPARAGINE SYNTHETASE1
gene is dependent on a G-box element present in the
promoter. Increased bZIP11 expression leads to decreased
proline and increased phenylalanine levels. A model is
proposed in which sugar signals control amino acid levels
via the bZIP11 transcription factor.},
