Previous analyses suggested that the Nicotiana sylvestris CMSII mutant carried a large deletion in its mitochondrial genome. Here, we show by cosmid mapping that the deletion is 60 kb in length and contains several mitochondrial genes or ORFs, including the complex I nad7 gene. However, due to the presence of large duplications in the progenitor mitochondrial genome, the only unique gene that a...

Mounting evidence is merging to affirm the effectiveness of bacterial lipopolysaccharides (LPS) as biological control agents, inducers of innate immunity, and to stimulate/potentiate the development of defense responses in plants through protein phosphorylation-mediated signal perception/transduction responses. In vivo labeling of protein phosphorylation events during signal transduction indica...

Ribulose bisphosphate carboxylase/oxygenase was isolated and crystallized from eight plant species. Crystals grew from either of two similar sets of crystallizing conditions: crystals of the enzyme from alfalfa, corn, cotton, potato, spinach, tobacco, and tomato grew from solutions containing phosphate and polyethylene glycol 6000 as a precipitant, and those from potato, tobacco (both Nicotiana...
