Pteridines, 2023 The degradation of the green plant pigment chlorophyll has fascinated chemists and biologists alike over the last few decades. Bioactivities of the compounds formed in this biochemical degradation pathway, however, have only come to light recently. These

EIN3 and ORE1 Accelerate Degreening during Ethylene-Mediated Leaf Senescence by Directly Activating Chlorophyll Catabolic Genes in Arabidopsis. [PDF]
PLoS Genetics, 2015 Degreening, caused by chlorophyll degradation, is the most obvious symptom of senescing leaves. Chlorophyll degradation can be triggered by endogenous and environmental cues, and ethylene is one of the major inducers.

Annual Review of Plant Physiology and Plant Molecular Biology, 1999 ▪ Abstract Although the loss of green color in senescent leaves and ripening fruits is a spectacular natural phenomenon, research on chlorophyll breakdown has been largely neglected until recently. This review summarizes knowledge about the fate of chlorophyll in degreening tissues that has been gained during the past few years. Structures of end- and

Research Progress on the Degradation of and Preservation Techniques for Chlorophyll in Vegetables during Thermal Processing [PDF]
Shipin KexueChlorophyll imparts a green color to vegetables and possesses antioxidant, antimicrobial, immunomodulatory, and anticancer functions. However, it is unstable during thermal processing and easily degraded, resulting in loss of its bioactivity, thereby ...

Plant Physiology, 2022 Abstract Chlorophyll (Chl) serves a number of essential functions, capturing and converting light energy as a component of photosystem supercomplexes. Chl degradation during leaf senescence is also required for adequate degeneration of chloroplasts and salvaging of nutrients from senescent leaves.

A New Chlorophyll Degradation Pathway [PDF]
The Plant Cell, 2009 Chlorophyll degradation is vital during leaf senescence and fruit ripening, as it allows for recycling of nitrogen and other nutrients and for protection from buildup of phototoxic chlorophyll intermediates ([Hortensteiner, 2006][1]).
