The cytoskeleton enhances gene expression in the response to the Harpin elicitor in grapevine.

ABSTRACT: The cytoskeleton undergoes dramatic reorganization during plant defence. This response is generally interpreted as part of the cellular repolarization establishing physical barriers against the invading pathogen. To gain insight into the functional significance of cytoskeletal responses for defence, two Vitis cell cultures that differ in their microtubular dynamics were used, and the cytoskeletal response to the elicitor Harpin in parallel to alkalinization of the medium as a fast response, and the activation of defence-related genes were followed. In one cell line derived from the grapevine cultivar 'Pinot Noir', microtubules contained mostly tyrosinylated alpha-tubulin, indicating high microtubular turnover, whereas in another cell line derived from the wild grapevine V. rupestris, the a
