General Information

General Information Comment Organism
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
