      abstract     = {The location of the phloem within a plant, and its
                      vulnerability to disruption, make it a difficult tissue to
                      study and therefore non-invasive studies of phloem
                      functionality are important. Here we compare, phloem
                      transport, measured non-invasively, in wild type Arabidopsis
                      thaliana, and transposon-insertion mutants for AtSUC1 or
                      AtSUC2, giving in vivo information on the importance of
                      these sucrose transporters for phloem transport. The suc2
                      mutant showed an increase in both phloem leakage and
                      transport time, consistent with reduced sucrose uptake into
                      both transport and collection phloem. The results are
                      consistent with the AtSUC2 transporter being important for
                      retrieval of leaked sucrose in the transport phloem of
                      Arabidopsis. There was no difference in phloem transport
                      properties between the wild type and the suc1 mutants,
                      implying that the AtSUC1 transporter does not play a
                      significant role within the transport phloem of Arabidopsis
                      under the conditions of our study.},
