These results support the presence of a unique binary defense system against insect herbivores involving chlorophyll and CLH.
Title: Reexamination of chlorophyllase function implies its involvement in defense against chewing herbivores.

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 AtCLH1 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.
