      abstract     = {The strong regulation of plant carbon allocation and growth
                      by trehalose metabolism is important for our understanding
                      of the mechanisms that determine growth and yield, with
                      obvious applications in crop improvement. To gain further
                      insight on the growth arrest by trehalose feeding, we first
                      established that starch-deficient seedlings of the plastidic
                      phosphoglucomutase1 mutant were similarly affected as the
                      wild type on trehalose. Starch accumulation in the source
                      cotyledons, therefore, did not cause starvation and
                      consequent growth arrest in the growing zones. We then
                      screened the FOX collection of Arabidopsis (Arabidopsis
                      thaliana) expressing full-length cDNAs for seedling
                      resistance to 100 mm trehalose. Three independent transgenic
                      lines were identified with dominant segregation of the
                      trehalose resistance trait that overexpress the bZIP11 (for
                      basic region/leucine zipper motif) transcription factor. The
                      resistance of these lines to trehalose could not be
                      explained simply through enhanced trehalase activity or
                      through inhibition of bZIP11 translation. Instead,
                      trehalose-6-phosphate (T6P) accumulation was much increased
                      in bZIP11-overexpressing lines, suggesting that these lines
                      may be insensitive to the effects of T6P. T6P is known to
                      inhibit the central stress-integrating kinase SnRK1 (KIN10)
                      activity. We confirmed that this holds true in extracts from
                      seedlings grown on trehalose, then showed that two
                      independent transgenic lines overexpressing KIN10 were
                      insensitive to trehalose. Moreover, the expression of marker
                      genes known to be jointly controlled by SnRK1 activity and
                      bZIP11 was consistent with low SnRK1 or bZIP11 activity in
                      seedlings on trehalose. These results reveal an astonishing
                      case of primary metabolite control over growth by way of the
                      SnRK1 signaling pathway involving T6P, SnRK1, and bZIP11.},
