Fates of chlorophylls and related pigments in the ozone-exposed leaves of ozone-sensitive tobacco variety Bel-W3 in vivo and also in vitro of ozone-sensitive tobacco variety Bel-W3 in vivo and also in vitro

Abstract

It is well known that ozone induces the loss of chlorophylls (Chls) in plants. However, the mechanism for ozone-induced Chl degradation is still unknown. We attempted the search for ozone-dependent Chl degradation paths in both in vivo in leaves and in vitro , using HPLC and TOF-MS.
