The cytokinin, N(6)-(Delta(2)-isopentenyl)adenine, is found to be at least 3.3 times as active as N(6)-(Delta(2)-isopentenyl)adenosine in promoting the growth of cytokinin-requiring tobacco (Nicotiana tabacum) callus. Absorption rates of N(6)-(Delta(2)-isopentenyl)adenine and

The two peroxidase isoenzyme groups (G(I) and G(III)) localized in the cell walls of tobacco (Nicotiana tabacum L.) tissues were compared with respect to their capacity for NADH-dependent H(2)O(2) formation. Peroxidases of the G(III) group are slightly more active than those of the G(I) group when

Synthetic nitroguanidine derivatives can be used as alternatives to the traditional adenine-containing cytokinins used in plant tissue culture. First, nitroguanidine derivatives (NG) mimicked the typical activity of two standard cytokinins, 6-benzylaminopurine (BAP) and 2-isopentenyladenine (2iP) in

De novo synthesis of mevalonic acid, which is catalyzed by 3-hydroxy-3-methylglutaryl coenzyme A reductase, is the first committed step in the formation of isoprenoid compounds. Various studies have shown that mevalonic acid-derived compounds are required for growth of plant and animal cells, a

Ammonium (NH4+) instead of nitrate (NO3-) as the nitrogen (N) source for tobacco (Nicotiana tabacum L.) cultivated in a pH-buffered nutrient solution resulted in decreased shoot and root biomass. Reduction of shoot fresh weight was mainly related to inhibition of leaf growth, which was already

Three SAH hydrolase inhibitors, (RS)-3-adenin-9-yl-2-hydroxypropanoic acid (isobutyl ester) [(RS)-AHPA]; (RS)-9-(2,3-dihydroxypropyl)adenine [(RS)-DHPA] and the carbocyclic analog of 3-deazaadenosine (C-c3Ado) were evaluated for their inhibitory activity against tobacco mosaic virus (TMV) and potato

Previous reports on the incorporation of [(14)C]adenine into adenosine-3':5'-cyclic monophosphate (cyclic AMP) in oat (Avena sativa L.) and maize (Zea mays L.) coleoptile sections, chick-pea (Cicer arietinum L.) embryos and barley (Hordeum vulgare L.) aleurone layers were reexamined. Separation of
Potato Virus Y HCPro Suppression of Antiviral Silencing in Nicotiana benthamiana Plants Correlates with Its Ability To Bind In Vivo to 21- and 22-Nucleotide Small RNAs of Viral Sequence.

We have investigated short and small RNAs (sRNAs) that were bound to a biologically active hexahistidine-tagged Potato virus Y (PVY) HCPro suppressor of silencing, expressed from a heterologous virus vector in Nicotiana benthamiana plants, and purified under nondenaturing conditions. We found that
Expression of Pokeweed Antiviral Protein in Transgenic Plants Induces Virus Resistance in Grafted Wild-Type Plants Independently of Salicylic Acid Accumulation and Pathogenesis-Related Protein Synthesis.

Pokeweed antiviral protein (PAP), a 29-kD protein isolated from Phytolacca americana, inhibits translation by catalytically removing a specific adenine residue from the large rRNA of the 60S subunit of eukaryotic ribosomes. Transgenic tobacco (Nicotiana tabacum) plants expressing PAP or a variant

Viroid-caused pathogenesis is a specific process dependent on viroid and host genotype(s), and may involve viroid-specific small RNAs (vsRNAs). We describe a new PSTVd variant C3, evolved through sequence adaptation to the host chamomile (Matricaria chamomilla) after biolistic inoculation with

Melandrium yellow fleck bromovirus (MYFV) systemically infected Arabidopsis thaliana, although the susceptibility of several A. thaliana accessions to MYFV differed from their susceptibility to the other two bromoviruses infecting A. thaliana. We constructed full-length cDNA clones of MYFV genomic

N5-Formyltetrahydrofolate (leucovorin) counteracted methotrexate toxicity in suspension cultures of Nicotiana tabacum var. Xanthi. Methotrexate at 50 nM inhibited growth of the tobacco cell cultures by 87%. Leucovorin at 200 uM reduced growth inhibition in methotrexate-treated cultures to 37%, but
