PGL, encoding chlorophyllide a oxygenase 1, is mainly expressed in the chlorenchyma
-
small young cells adjacent to the epidermis cells with less frequent fusion enzyme signal (group III mutants), fusion enzyme signals only in small young cells adjacent to the epidermis cells (group V mutants - impaired chloroplast development with less chlorophyll)
-
cotyledons, uniform distribution of the fusion enzyme signal within the chloroplast (group 1 mutants - defects in specific steps of the chlorophyllide a enzyme regulation), punctate fusion enzyme signal (group II mutants - defect in chloroplast proteases), fusion enzyme signal only in guard cells (group VI mutants - slight inhibition of enzyme degradation or slightly enhanced enzyme synthesis)
-
cotyledons, uniform distribution of the fusion enzyme signal within the chloroplast (group I mutants - defects in specific steps of the chlorophyllide a enzyme regulation), punctate fusion enzyme signal (group II mutants - defect in chloroplast proteases), fusion enzyme signal dispersed within chloroplasts and at the same time high-intensity signals localized in confined areas within chloroplasts (group III mutants)

-
low activity in etiolated leaves, higher activity in green mature leaves
-
wild-type enzyme expression begins in de-etiolation phase
