Basic mutant information
Mutant name	BCG
Mutant/Transgenic	transgenic
Ecotype	Col-0
Mutagenesis type	transgene
(Semi-)Dominant/Recessive	dominant
Description	The BC domains of CAO were fused with GFP and expressed in the chlorophyll b-less ch1-1 mutant that lacks native CAO protein. BCG plants exhibit a stay-green phenotype during age-dependent senescence.

Mutated genes
Locus name	AT1G44446
Alias	CAO
Organism	Arabidopsis thaliana
Description	Encodes chlorophyllide a oxygenase which converts chlorophyllide a to chlorophyllide b by catalyzing two successive hydroxylations at the 7-methyl group of chlorophyllide a.
