Cytoplasmic line 2 (CL2) is a chlorophyll mutant that was selected from a plastid mutator genotype in barley. The dynamics of greening and plastid development of CL2 first-leaf blade contrasts with that of monocots. Previous characterizations of CL2 suggested that this mutant has a delay of plastid gene translation during embryogenesis. We hypothesize that(More)
A cytoplasmically inherited chlorophyll-deficient mutant of barley (Hordeum vulgare) termed cytoplasmic line 3 (CL3), displaying a viridis (homogeneously light-green colored) phenotype, has been previously shown to be affected by elevated temperatures. In this article, biochemical, biophysical, and molecular approaches were used to study the CL3 mutant(More)
Fas (CD95, APO-1), a member of the TNF superfamily, is a prototypical “death receptor” which transduces apoptotic signals in a variety of cell types. However, cell death is not the only possible outcome of Fas signalling. Fas engagement by Fas Ligand can also trigger proliferation or differentiation, promote tumour progression and angiogenesis, and induce(More)
The IF1 protein is one of the factors controlling translation initiation in bacteria. This protein is encoded by the infA gene, which, in several higher plants, is located in the plastome. Cytoplasmic Line 2 (CL2), an alboviridis barley mutant, was the first to be proposed as an infA gene mutation (T 157 C) in higher plants. This mutant was isolated from a(More)
The barley chloroplast mutator (cpm) is an allele of a nuclear gene that when homozygous induces several types of cytoplasmically inherited chlorophyll deficiencies. In this work, a plastome Targeting Induced Local Lesions in Genomes (TILLING) strategy based on mismatch digestion was used on families that carried the cpm genotype through many generations.(More)
