The progress in understanding the control of eukaryotic transcription can only be appreciated by realizing that seven years ago we did not know the primary str978-1-4684-6813-7978-1-4684-6811-3

Plant Resistance to Ozone: the Role of Ascorbatehich vegetation is exposed in many parts of Central/Southern Europe, North/South America and Asia (Yunus and Iqbal 1996). In many of these regions, there is incontrovertible evidence that O. levels are high enough to reduce crop yields (Heck et al. 1983; Runeckles and Chevone 1992; Turcsányi et al.
