Abstract:
Plants exhibit considerable variation in their sensitivity to the photochemical oxidant ozone (O3). However, the mechanisms underlying this variation are just beginning to be unravelled. Since O3 initially promotes extracellular oxidative stress, much recent attention has been paid to fathoming the potential of the pool of ascorbate located in the leaf cell walls in screening the plasmalemma from O3-induced oxidative insult. The work proposed forms a logical next-step in these investigations and is designed to test or theory (Plochl et al., 2000) that apoplast pH predominantly controls the partitioning of ascorbate between leaf apoplast and symplast. The work will lead to a better understanding of fundamental mechanisms controlling tolerance to O3 and will make a potentially important contribution to the derivation of thresholds for flux-based Critical Level guidelines aimed at the protection of natural (and semi-natural) ecosystems from O3.
