Phenotypic and Genetic Analysis of det2, a New Mutant That Affects Light-Regulated Seedling Development in Arabidopsis.
TLDR
The greening phenotypes produced by recessive mutations in a gene designated de-etiolated-2 (DET2) are described, implying that DET1 and DET2 function in distinct pathways that affect downstream light-regulated genes.
Arabidopsis mutants define downstream branches in the phototransduction pathway.
TLDR
Genetic and phenotypic analyses indicate that most of the mutations are recessive and define at least three loci (doc1, doc2, doc3), and all three doc mutations are much more specific in derepressing the expression of CAB.
cop1: a regulatory locus involved in light-controlled development and gene expression in Arabidopsis.
TLDR
It is concluded that in seedlings and adult plants, the wild-type cop1 gene product normally acts in darkness to repress the expression of genes involved in the dark-adaptive developmental and that regulatory photoreceptors act to reverse this action upon exposure to light.
COP9: a new genetic locus involved in light-regulated development and gene expression in arabidopsis.
TLDR
The results suggest that the cop9 and cop1 mutations result in the the same range of phenotypes and therefore COP9 and COP1 loci may encode closely related components in the same regulatory pathway.
Mutations in the DET1 gene affect cell-type-specific expression of light-regulated genes and chloroplast development in Arabidopsis

TLDR
It is suggested that the DET1 gene product is a negatively acting regulatory molecule that is used in common by the light stimulus transduction pathway and by temporal or spatial regulatory signals in plants.
A genetic model for light-regulated seedling development in Arabidopsis
  • Environmental Science, Biology
  • 2005
TLDR
The phenotypes of doubly mutant strains suggest a hierarchical regulatory network among these genes in the control of the switch from etiolated to de-etiolated growth strategies.
COP 9 : A New Genetic Locus lnvolved in Light-Regulated Development and Gene Expression in Arabidopsis
TLDR
The results suggest that the cop9 and cop l mutatlons result in the same range of phenotypes and therefore COP9 and COPl loci may encode closely related components ln the same regulatory pathway.
A New Class of Arabidopsis Constitutive Photomorphogenic Genes lnvolved in Regulating Cotyledon Development
TLDR
A new class of constitutive photomorphogenic mutants, cop2, cop3, and cop4, are identified, in which dark-grown seedlings have open and enlarged cotyledons resembling those of light-grown wild-type seedlings, suggesting that the COP4 locus may be involved in both light-signaling and gravity-sensing processes.
CUE1: A Mesophyll Cell-Specific Positive Regulator of Light-Controlled Gene Expression in Arabidopsis.
TLDR
It is proposed that CUE1 is a cell-specific positive regulator linking light and intrinsic developmental programs in Arabidopsis leaf mesophyll cells, because cue1 mutants are severely deficient at establishing photoautotrophic growth.

Expression of Light-Harvesting Chlorophyll a/b-Protein Genes Is Phytochrome-Regulated in Etiolated Arabidopsis thaliana Seedlings.
TLDR
The AB140 gene offers an attractive target for further analysis of phytochrome-regulated gene expression in Arabidopsis, and is further characterized by mapping its 5' and 3' transcript termini.

TLDR
The two pea rbcS genes were transferred into the petunia genome and it was found that their phytochrome and blue-light responses are recapitulated in the appropriate developmental stages of the transgenic plants.
Chloroplast gene expression in nuclear, photosynthetic mutants of maize.
TLDR
In most cases the nuclear lesions act within the chloroplast at a post‐transcriptional level to prevent expression of chloropine‐encoded polypeptides, and one mutant, hcf‐38, does show striking alterations in the abundance and size of many chloroplane transcripts.
Use of nuclear mutants in the analysis of chloroplast development.
TLDR
The range of pleiotropic effects of hcf mutations indicates that the mutations identify nuclear genes whose products are involved in a number of different steps in chloroplast development.
Transcriptional regulation of the Arabidopsis thaliana chalcone synthase gene.
TLDR
The accumulation of CHS mRNA in response to high-intensity light was due, at least in part, to an increased rate of transcription of the CHS gene as demonstrated by nuclear runoff experiments.
Structure and expression of three light-harvesting chlorophyll a/b-binding protein genes in Arabidopsis thaliana.
TLDR
This paper characterized a member of the low copy DNA component: the gene family for the light-harvesting chlorophyll a/b-protein, which is unusual in that it contains far fewer members than the 7-16 coding sequences for this protein found in other plants.
Light-regulated gene expression during maize leaf development

An evolutionarily conserved protein binding sequence upstream of a plant light-regulated gene.
TLDR
A protein factor, identified in nuclear extracts obtained from tomato and Arabidopsis seedlings, specifically binds upstream sequences from the plant light-regulated gene family encoding the small subunit of ribulose 1,5-bisphosphate carboxylase/oxygenase (RBCS).
Plastid transcription activity and DNA copy number increase early in barley chloroplast development.
TLDR
It is shown that plastid transcriptional activity and DNA copy number increase early in chloroplast development and that transcriptionalactivity per DNA template varies up to 5-fold during barley leaf biogenesis.
