Arabidopsis Map-Based Cloning in the Post-Genome Era
TLDR
The Cereon Collection is described and it is shown how it can be used in a generic approach to mutation mapping in Arabidopsis and the map-based cloning of theVTC2 gene is presented. Expand
Superoxide dismutase in Arabidopsis: an eclectic enzyme family with disparate regulation and protein localization.
TLDR
This is the first report of a large-scale analysis of the regulation of multiple SOD proteins in a plant species and the four proteins identified were differentially regulated in response to various light regimes, ozone fumigation, and ultraviolet-B irradiation. Expand
Arabidopsis Flavonoid Mutants Are Hypersensitive to UV-B Irradiation.
TLDR
Results demonstrate that both flavonoids and other phenolic compounds play important roles in vivo in plant UV-B protection and are highly sensitive to the damaging effects ofUV-B radiation. Expand
Arabidopsis UVR8 Regulates Ultraviolet-B Signal Transduction and Tolerance and Contains Sequence Similarity to Human Regulator of Chromatin Condensation 1
TLDR
Results suggest that UVR8acts in a UV-B signal transduction pathway leading to induction of flavonoid biosynthesis, an indication of increasedUV-B injury. Expand
Genetic evidence for the role of GDP-mannose in plant ascorbic acid (vitamin C) biosynthesis.
TLDR
By using a combination of biochemical, molecular, and genetic techniques, it is demonstrated that the VTC1 locus encodes a GDP-mannose pyrophosphorylase (mannose-1-P guanyltransferase). Expand
Identification of ascorbic acid-deficient Arabidopsis thaliana mutants.
TLDR
A novel AsA assay is used to isolate four vtc mutants that define three additional VTC loci, and a second mutant allele of VTC1 is isolated, providing strong evidence for the recently proposed role of GDP-mannose in AsA biosynthesis. Expand
Monoterpenes in the glandular trichomes of tomato are synthesized from a neryl diphosphate precursor rather than geranyl diphosphate
TLDR
The data indicate that, contrary to the textbook view of geranyl diphosphate as the “universal” substrate of monoterpene synthases, in tomato glands neryl diph phosphate serves as a precursor for the synthesis ofmonoterpenes. Expand
Arabidopsis cyt1 mutants are deficient in a mannose-1-phosphate guanylyltransferase and point to a requirement of N-linked glycosylation for cellulose biosynthesis
TLDR
The results suggest that N-glycosylation is required for cellulose biosynthesis and that a deficiency in this process can account for most phenotypic features of cyt1 embryos. Expand
Environmental stress sensitivity of an ascorbic acid-deficient Arabidopsis mutant.
TLDR
It is shown that the soz1 mutant is hypersensitive to both sulfur dioxide and ultraviolet B irradiation, thus implicating ascorbate in defense against varied environmental stresses and indicating that screening for ozone-sensitive mutants is a powerful method for identifying physiologically important antioxidant mechanisms and signal transduction pathways. Expand
Arabidopsis Mutants Lacking Phenolic Sunscreens Exhibit Enhanced Ultraviolet-B Injury and Oxidative Damage
TLDR
Results demonstrate that, in A. thaliana, hydroxycinnamates are more effective UV-B protectants than flavonoids, and indicate that A.Thaliana responds toUV-B as an oxidative stress, and sunscreen compounds reduce the oxidative damage caused by UV- B. Expand
