Characterization of the pheophorbide a oxygenase/phyllobilin pathway of chlorophyll breakdown in grasses.

Planta - 1 Oct 2018

Das Aditi, Christ Bastien, Hörtensteiner Stefan

Abstract excerpt

MAIN CONCLUSION: Although the PAO/phyllobilin pathway of chlorophyll breakdown is active in grass leaf senescence, the abundance of phyllobilins is far below the amount of degraded chlorophyll. The yellowing of fully developed leaves is the most prominent visual symptom of plant senescence. Thereby, chlorophyll is degraded via the so-called pheophorbide a oxygenase (PAO)/phyllobilin pathway to a species-specific...
