The function of ascorbate oxidase in tobacco.

Plant physiology - 1 Jul 2003

Pignocchi Cristina, Fletcher John M, Wilkinson Joy E, Barnes Jeremy D, Foyer Christine H

Abstract excerpt

The function of the apoplastic enzyme ascorbate oxidase (AO) was investigated in tobacco (Nicotiana tabacum). The abundance of AO mRNA was up-regulated by light. Cytosolic ascorbate peroxidase (APX1) transcripts were also highest in the light. In contrast, L-galactono-gamma-lactone dehydrogenase, stromal APX, and thylakoid APX transcripts remained constant over the day/night cycle. Salicylic acid inhibited...
