Cloned(Commentary)

Cloned (Comment) Organism
gene pgl, recombinant expression of truncated protein OsCAO1pgl fused with GFP (35S::OsCAO1pgl-GFP) and transformed into Nicotiana benthamiana via Agrobacterium sp., specific expression in chloroplasts although the truncated enzyme lacks the signal sequence Oryza sativa Japonica Group

Protein Variants

Protein Variants Comment Organism
additional information generation of the truncated enzyme mutant OsCAO1pgl. The premature translational termination of OsCAO1 in mutant pgl does not affect OsCAO1 localization, the mutation nevertheless results in the pale-green phenotype. Expression levels of Chl synthesis-associated genes in mutant pgl, and phenotype, overview Oryza sativa Japonica Group

Localization

Localization Comment Organism GeneOntology No. Textmining

Expression

Organism Comment Expression
Oryza sativa Japonica Group PGL, encoding chlorophyllide a oxygenase 1, is induced in the light-dependent chlorophyll synthesis process up

General Information

General Information Comment Organism
malfunction rice mutant pale green leaf (pgl) exhibits a lower chlorophyll content with a reduced and disorderly thylakoid ultrastructure, which decreases the photosynthesis rate and results in reduced grain yield and quality compared to the wild-type. In addition, mutant pgl exhibits premature senescence in both natural and dark-induced conditions and more severe chlorophyll degradation and reactive oxygen species accumulation than does the wild-type. Mutant pgl is sensitive to heat stress. The pgl plants exhibit a pale-green leaf in the paddy field and present a severe withered phenotype in the leaf tip Oryza sativa Japonica Group
physiological function PGL, encoding chlorophyllide a oxygenase 1, impacts leaf senescence and indirectly affects grain yield and quality in rice. The enzyme is required for the light-dependent Chl synthesis during greening of etiolated plants. PGL might also affects the ROS scavenging system under low light Oryza sativa Japonica Group
