Rice sucrose transporter1 (OsSUT1) up-regulation in xylem parenchyma is caused by aphid feeding on rice leaf blade vascular bundles

The role of the sucrose transporter OsSUT1 in assimilate retrieval via the xylem, as a result of damage to and leakage from punctured phloem was examined after rusty plum aphid ( Hysteroneura setariae , Thomas) infestation on leaves from 3‐week‐old rice ( Oryza sativa L. cv Nipponbare) plants. Leaves were examined over a 1‐ to 10‐day infestation time course, using a combination of gene expression and β‐glucuronidase ( GUS ) reporter gene...
