The levels of mRNA of two enzymes involved in chlorophyll catabolism in Arabidopsis, products of two chlorophyllase genes, AtCLH1 and AtCLH2, dramatically increase upon illumination with white light.
Title: Expression of enzymes involved in chlorophyll catabolism in Arabidopsis is light controlled.

Data conclude that AtCLH2 might be required at the initial stage of leaf senescence, quite likely playing a role in converting Chl b to a.
Title: Repression of AtCLH1 expression results in a decrease in the ratio of chlorophyll a/b but doesnot affect the rate of chlorophyll degradation during leaf senescence.

AtCLHs are not required for senescence-related chlorophyll breakdown in vivo and propose that genuine chlorophyllase has not yet been molecularly identified
Title: The chlorophyllases AtCLH1 and AtCLH2 are not essential for senescence-related chlorophyll breakdown in Arabidopsis thaliana.

We propose that AtCLH1 is involved in plant damage control and can modulate the balance between different plant defense pathways.
Title: Chlorophyllase 1, a damage control enzyme, affects the balance between defense pathways in plants.
