Chlorophyll breakdown is one of the most obvious signs of leaf senescence and fruit
ripening. The resulting yellowing of leaves can be observed every autumn, and the color …

In land plants, chlorophyll is broken down to colorless linear tetrapyrroles in a highly
conserved multi-step pathway. The pathway is termed the 'PAO pathway', because the …

During leaf senescence, chlorophyll is removed from thylakoid membranes and converted in
a multistep pathway to colorless breakdown products that are stored in vacuoles …

One important reaction of chlorophyll (chl) breakdown during plant senescence is the
removal of the lipophilic phytol moiety by chlorophyllase. AtCLH1 and AtCLH2 were …

Plants have an ability to prevent chlorophyll accumulation, which would mask the bright
flower color, in their petals. In contrast, leaves contain substantial amounts of chlorophyll, as …

Chlorophyll (Chl) is one of Nature's most complex pigments to biosynthesize and derivatize.
This pigment is vital for survival and also paradoxically toxic if overproduced or released …

Recent identification of NYE1/SGR1 brought up a new era for the exploration of the
regulatory mechanism of Chlorophyll (Chl) degradation. Cluster analysis of senescence …

Chlorophyllase (CLH), which catalyzes the release of the phytol chain from chlorophyll (Chl),
has been long considered to catalyze the first step of Chl degradation. Arabidopsis contains …

Broccoli is an important component of the human diet with a high nutritional value. This
vegetable is harvested when its development is not complete, triggering a quick senescence …

The main objective of this work was to compare activity of chlorophyllase (chlase) in green
and non-green sectors of leaves. Our results show that various plants exhibited different …
