malfunction | identification of constitutive photomorphogenic mutants, cop2, cop3, and cop4,in which dark-grown seedlings have open and enlarged cotyledons resembling those of light-grown wild-type seedlings. Mutations in each of the three loci alleviate the normal inhibition of cell-type differentiation, cell enlargement, and lateral cell division observed in cotyledons of dark-grown wild-type seedlings, but do not affect plastid differentiation. Cop4 mutation also leads to high-leve1 dark expression of nuclear, but not plastid-encoded, light-inducible genes | Arabidopsis thaliana |
metabolism | epistatic relationships of these three mutations to previously characterized phytochrome-deficient mutations suggest that COP2, COP3, and COP4 may act downstream of phytochrome in the light regulatory pathway | Arabidopsis thaliana |
physiological function | the COP4 locus may be involved in both light-signaling and gravity-sensing processes. COP4 modulates cabl promoter activity through a pathway distinct from that of COPl and COP9, nuclear cabl gene encodes a chlorophyll alb binding protein of the photosynthetic light-harvesting complex. Modulation of cabl promoter activity by light and by the cop4 mutation | Arabidopsis thaliana |
