Suppressors of an Arabidopsis thaliana phyB mutation identify genes that control light signaling and hypocotyl elongation.
Ambient light controls the development and physiology of plants. The Arabidopsis thaliana photoreceptor phytochrome B (PHYB) regulates developmental light responses at both seedling and adult stages. To identify genes that mediate control of development by light, we screened for suppressors of the long hypocotyl phenotype caused by a phyB mutation. Genetic analyses show that the shy (short hypo...
متن کاملIdentification of an allele of VAM3/SYP22 that confers a semi-dwarf phenotype in Arabidopsis thaliana.
The short stem and midrib (ssm) mutants of Arabidopsis thaliana show both semi-dwarf and wavy leaf phenotypes due to defects in the elongation of the stem internodes and leaves. Moreover, these abnormalities cannot be recovered by exogenous phytohormones. ssm was originally identified as a single recessive mutant of the ecotype Columbia (Col-0), but genetic crossing experiments have revealed th...

متن کاملIdentification of metabolites in Arabidopsis thaliana
Identification of Arabidopsis thaliana Col.0 metabolites by use of NMR spectroscopy is described in this chapter. Among the different extraction solvent tested, MeOD was the best solvent to extract phenolic compounds from Arabidopsis. By column chromatography using Sephadex LH-20 and prep HPLC, several flavonoids were isolated from the methanol extract of Arabidopsis, and their structures were ...
متن کاملSpontaneous deleterious mutation in Arabidopsis thaliana.
The frequency and selective impact of deleterious mutations are fundamental parameters in evolutionary theory, yet they have not been directly measured in a plant species. To estimate these quantities, we allowed spontaneous mutations to accumulate for 10 generations in 1,000 inbred lines of the annual, self-fertilizing plant Arabidopsis thaliana and assayed fitness differences between generati...
