      abstract     = {Herbivore attack elicits costly defenses that are known to
                      decrease plant fitness by using resources that are normally
                      slated for growth and reproduction. Additionally, plants
                      have evolved mechanisms for tolerating attack, which are not
                      understood on a molecular level. Using 11C-photosynthate
                      labeling as well as sugar and enzyme measurements, we found
                      rapid changes in sink-source relations in the annual
                      Nicotiana attenuata after simulated herbivore attacks, which
                      increased the allocation of sugars to roots. This
                      herbivore-induced response is regulated by the beta-subunit
                      of an SnRK1 (SNF1-related kinase) protein kinase, GAL83,
                      transcripts of which are rapidly down-regulated in source
                      leaves after herbivore attack and, when silenced, increase
                      assimilate transport to roots. This C diversion response is
                      activated by herbivore-specific elicitors and is independent
                      of jasmonate signaling, which regulates most of the plant's
                      defense responses. Herbivore attack during early stages of
                      development increases root reserves, which, in turn, delays
                      senescence and prolongs flowering. That attacked
                      GAL83-silenced plants use their enhanced root reserves to
                      prolong reproduction demonstrates that SnRK1 alters resource
                      allocation so that plants better tolerate herbivory. This
                      tolerance mechanism complements the likely defensive value
                      of diverting resources to a less vulnerable location within
                      the plant.},
