fluoride/nicotiana

Data on the short-term effects of fumigation with hydrogen fluoride (HF) on the response behavior of the Nicotiana tabacum L. cv. St. Karabalar 6265 are being presented. Growth rate, fluoride accumulation in leaves and soils, and degradation in chlorophyll and nicotine contents of the plant species

In this paper, we report a novel method for delivering genes into chloroplasts of tobacco cells using laser microablation. The plasmid pLD200-GFP was introduced into chloroplasts of Nicotiana tabacum cv. Xanthi guard cells and transient GFP expression was detected in the chloroplasts after 2-3 d of

We report the presence of an ATP-dependent proteolytic activity in spinach (Spinacia oleracea) leaf mitochondria. The proteolysis was observed as degradation of newly imported precursor protein. The precursor studied was that of the ATP synthase F1 beta subunit of Nicotiana plumbaginifolia,

A biochemical and cytochemical study has been made of the distribution of β-glycerophosphatase (EC 3.1.3.2) activity in mature and differentiating phloem cells of Nicotiana tabacum L. and the pH dependence and kinetics of β-glycerophosphate hydrolysis of homogenates of fresh leaf midveins and

Urea isoelectric focusing of dissociated, carboxymethylated Nicotiana tabacum ribulose-1,5-bisphosphate carboxylase/oxygenase reveals catalytic subunit microheterogeneity. Aggregated or nonaggregated sucrose gradient-purified preparations and the crystalline protein displayed essentially identical

A biochemical and cytochemical study has been made of the distribution of ATPase in mature and differentiating phloem cells of Nicotiana tabacum and of the substrate specificity and effects of fixation on enzyme activity. Homogenates of unfixed leaf midveins and midveins fixed in

Arabinogalactan-proteins (AGPs) from the styles of Nicotiana alata were isolated by ion exchange and gel filtration chromatography. After deglycosylation by anhydrous hydrogen fluoride, the protein backbones were fractionated by reversed-phase HPLC. One of the protein backbones, containing mainly
