      abstract     = {Jasmonic acid (JA) is a crucial plant defence signalling
                      substance that has recently been shown to mediate
                      herbivory-induced root growth reduction in the ecological
                      model species Nicotiana attenuata. To clarify whether
                      JA-induced reduction of root growth might be a general
                      response increasing plant fitness under biotic stress, a
                      suite of experiments was performed with the model plant
                      Arabidopsis thaliana. JA bursts were elicited in leaves of
                      A. thaliana in different ways. Root growth reduction was
                      neither induced by foliar application of herbivore oral
                      secretions nor by direct application of methyl jasmonate to
                      leaves. Root growth reduction was observed when leaves were
                      infected with the pathogen Pseudomonas syringae pv. tomato,
                      which persistently induces the JA signalling pathway. Yet,
                      high resolution growth analyses of this effect in wild type
                      and JA biosynthesis knock-out mutants showed that it was
                      elicited by the bacterial toxin coronatine that suggests
                      ethylene- but not JA-induced root growth reduction in A.
                      thaliana. Overall, the results demonstrate that the reaction
                      of root growth to herbivore-induced JA signalling differs
                      among species, which is discussed in the context of
                      different ecological defence strategies among species.},
