Wound healing in plants: Cooperation of copper amine oxidase and flavin-containing polyamine oxidase.

התחבר הרשם

Copper amine oxidases (CuAO) and flavin-containing amine oxidases (PAO) are hydrogen peroxide (H(2)O(2))-producing enzymes responsible for the oxidative de-amination of polyamines. Currently, a key role has been ascribed to apoplastic amine oxidases in plants, i.e., to behave as H(2)O(2)-delivering

Polyamines, hydroxycinnamoylputrescines, and root formation in leaf explants of tobacco cultivated in vitro: effects of the suicide inhibitors of putrescine synthesis.

In vitro formation of roots is obtained directly, without intermediate growth of callus, from foliar explants of a tobacco (Nicotiana tabacum) plant cultured on Murashige and Skoog medium containing IAA. Auxin-induced root formation was accompanied by significant changes in

Inverse Relationship between Polyamine Levels and the Degree of Phenotypic Alteration Induced by the Root-Inducing, Left-Hand Transferred DNA from Agrobacterium rhizogenes.

Floral induction in plants is a paradigm for signal perception, transduction, and physiological response. The introduction of root-inducing, left-hand transferred DNA (Ri T-DNA) into the genomes of several plants results in modifications of flowering (D Tepfer [1984] Cell 47: 959-967), including a

Barley contains two different isoforms of flavin-containing polyamine oxidase (BPAO1 and BPAO2). We have previously demonstrated that BPAO2 is a symplastic protein in barley leaves. On the contrary, maize polyamine oxidase (MPAO), the best characterized member of this enzyme class, is apoplastic.

Polyamines inhibit NADPH oxidase-mediated superoxide generation and putrescine prevents programmed cell death induced by polyamine oxidase-generated hydrogen peroxide.

Our previous results indicate that during protoplast isolation an oxidative burst occurs [A.K. Papadakis and KA Roubelakis-Angelakis (1999) Plant Physiol 127:197-205] and that suppression of totipotency is correlated with reduced antioxidant activity and low redox state [A.K. Papadakis et al.

Heterologous expression of a bacterial homospermidine synthase gene in transgenic tobacco: effects on the polyamine pathway.

התחבר הרשם

Homospermidine synthase (HSS) is a branch-point enzyme that links the secondary pathway (pyrrolizidine alkaloids) to primary metabolism (polyamines). Since the diamine putrescine is a precursor of homospermidine and nicotine in tobacco, we performed heterologous expression of a bacterial

Attenuation of the Phenotype Caused by the Root-Inducing, Left-Hand, Transferred DNA and Its rolA Gene (Correlations with Changes in Polyamine Metabolism and DNA Methylation).

We present four examples of attenuation of the transformed phenotype caused by the root-inducing, left-hand, transferred DNA from Agrobacterium rhizogenes in tobacco (Nicotiana tabacum). The first was associated with a genetic variable (homozygosity for the T-DNA), and the second was induced at the

Biochemical plant responses to ozone : I. Differential induction of polyamine and ethylene biosynthesis in tobacco.

Polyamine metabolism was examined in tobacco (Nicotiana tabacum L.) exposed to a single ozone treatment (5 or 7 hours) and then postcultivated in pollutant-free air. The levels of free and conjugated putrescine were rapidly increased in the ozone-tolerant cultivar Bel B and remained high for 3 days.

Ectopic expression of maize polyamine oxidase and pea copper amine oxidase in the cell wall of tobacco plants.

To test the feasibility of altering polyamine levels by influencing their catabolic pathway, we obtained transgenic tobacco (Nicotiana tabacum) plants constitutively expressing either maize (Zea mays) polyamine oxidase (MPAO) or pea (Pisum sativum) copper amine oxidase (PCuAO), two extracellular and

Expression of a human S-adenosylmethionine decarboxylase cDNA in transgenic tobacco and its effects on polyamine biosynthesis.

S-adenosylmethionine decarboxylase (SAMDC; EC 4.1.1.50) is a key regulatory enzyme in the polyamine biosynthetic pathway. Numerous studies have shown that the enzyme activity and polyamine levels are generally correlated with cellular growth in plants, animals and bacteria. In order to gain more

The high performance liquid chromatographic (HPLC) method of Flores and Galston (1982 Plant Physiol 69: 701) for the separation and quantitation of benzoylated polyamines in plant tissues has been widely adopted by other workers. However, due to previously unrecognized problems associated with the

Effects of the suicide inhibitors of arginine and ornithine decarboxylase activities on organogenesis, growth, free polyamine and hydroxycinnamoyl putrescine levels in leaf explants of Nicotiana xanthi N.C. Cultivated in vitro in a medium producing callus formation.

We studied the effects of dl-alpha-difluoromethylarginine (DFMA) and dl-alpha-difluoromethylornithine (DFMO), specific, irreversible inhibitors of arginine decarboxylase (ADC) and ornithine decarboxylase (ODC), respectively, on organogenesis growth and titers of free polyamines and conjugated

Polyamines (PAs) are small metabolites that are produced and oxidized in chloroplasts with an obscure mode of action. Recently, we showed that qE is stimulated by PAs in higher plants (Nicotiana tabacum) and in genetically modified plants with elevated thylakoid-associated PAs (Ioannidis and

We studied polyamine (PA) biosynthesis, oxidation and conjugation in asynchronously dividing cells of tobacco BY-2 cell suspension culture (Nicotiana tabacum L.) during 7-day growth cycle. We analyzed the levels of free and conjugated PAs and the activities of biosynthetic and catabolic enzymes
