A cDNA clone for a transcript preferentially expressed during an early phase of flooding was isolated from Nicotiana tabacum. Nucleotide sequencing of the cDNA clone identified an open reading frame that has high homology to the previously reported glycine-rich RNA-binding proteins. The open reading
Seven lines of haploid Nicotiana tabacum tissue culture selected for resistance to normally toxic levels of the glycine analog glycine hydroxamate, a competitive inhibitor of the glycine decarboxylase reaction, were investigated. The presence of glycine hydroxamate greatly increased the
Glycine max (Soybean) is the most important edible crop in Korea. In Korea, eight viruses have been reported to infect soybean, including Alfalfa mosaic virus (AMV), Cowpea mosaic virus (CPMV), Cucumber mosaic virus (CMV), Soybean dwarf virus (SbDV), Soybean mosaic virus (SMV), Soybean yellow common
Amount and products of photosynthesis during 10 minutes were measured at different (14)CO(2) concentrations in air. With tobacco (Nicotiana tabacum L. cv. Maryland Mammoth) leaves the percentage of (14)C in glycine plus serine was highest (42%) at 0.005% CO(2), and decreased with increasing CO(2)
The chromosomal stability of a number of somatic hybrids derived from soybean (Glycine max (L.) Merr.) and Nicotiana tabacum var. 'Xanthi' were investigated. Several of the hybrid cell lines retained more than half the complement of N. tabacum chromosomes after 7 months of culturing. A number of
Glycine betaine is an osmoprotectant found in many organisms, including bacteria and higher plants. The bacterium Escherichia coli produces glycine betaine by a two-step pathway where choline dehydrogenase (CDH), encoded by betA, oxidizes choline to betaine aldehyde which is further oxidized to
The regulatory region of the ribulose-1,5-bisphosphate carboxylase small subunit gene SRS4 from soybean (Glycine max) was cloned using TAIL-PCR and general PCR, and named the rbcS promoter. The promoter was fused with the GUS gene and introduced into Nicotiana tabacum via Agrobacterium-mediated leaf
Previous work has shown that tobacco (Nicotiana tabacum) plants engineered to express spinach choline monooxygenase in the chloroplast accumulate very little glycine betaine (GlyBet) unless supplied with choline (Cho). We therefore used metabolic modeling in conjunction with [(14)C]Cho labeling
Seed storage oil, in the form of triacylglycerol (TAG), is degraded to provide carbon and energy during germination and early seedling growth by the fatty acid β-oxidation in the peroxisome. Although the pathways for lipid degradation have been uncovered, understanding of the exact involved enzymes
The metabolic states and the uptake and metabolism of [1-(13)C]glucose, [2-(13)C]glycine, and [(15)N]glycine in intact Nicotiana tabacum L. (cv Xanthi) mesophyll protoplasts were measured by (13)C and (15)N nuclear magnetic resonance spectroscopy. Changes in the concentration of metabolites during
Gamma-tocopherol methyltransferase (γ-TMT) converts γ-toc to α-toc-the rate limiting step in toc biosynthesis. Sequencing results revealed that the coding regions of γ-TMT1 and γ-TMT3 were strongly similar to each other (93% at amino acid level). Based on the differences in the
Glyoxylate at a concentration of 10 millimolar caused 50% inhibition of decarboxylation of 20 millimolar [1-(14)C]glycine and accompanying synthesis of serine in a mitochondria-enriched preparation from tobacco (Nicotiana tabacum var. John Williams Broadleaf) leaves. None of the other compounds
Members of the Chenopodiaceae can accumulate high levels (>100 μmol·(g DW)(-1)) of glycine betaine (betaine) in leaves when salinized. Chenopodiaceae synthesize betaine by a two-step oxidation of choline (choline→betaine aldehyde→ betaine), with the second step catalyzed by betaine aldehyde
Phosphatidylinositol-specific phospholipase C (PI-PLC) hydrolyses phosphatidylinositol-4,5-bisphosphate to produce diacylglycerol and inositol 1,4,5-trisphosphate. It plays an important role in plant development and abiotic stress responses. However, systematic analysis and expression profiling of
A rare Gly210 deletion in protoporphyrinogen oxidase (PPO) was recently discovered in herbicide-resistant Amaranthus tuberculatus. According to the published X-ray structure of Nicotiana tabacum PPO, Gly210 is adjacent to, not in, the PPO active site, so it is a matter of interest to determine why
