Peach (Prunus persica) fruit ripening: aminoethoxyvinylglycine (AVG) and exogenous polyamines affect ethylene emission and flesh firmness.
The effect of various concentrations of aminoethoxyvinylglycine (AVG; 0.32 and 1.28 mM), an ethylene biosynthesis inhibitor, and of the polyamines putrescine (10 mM), spermidine (0.1, 1 and 5 mM) andExpand

Characterization of monocot and dicot plant S-adenosyl-l-methionine decarboxylase gene families including identification in the mRNA of a highly conserved pair of upstream overlapping open reading
S-Adenosyl-L-methionine decarboxylase (AdoMetDC; EC 4.1.1.50) is one of the key regulatory enzymes in the biosynthesis of polyamines. Isolation of genomic and cDNA sequences from rice and ArabidopsisExpand

Methyl jasmonate upregulates biosynthetic gene expression, oxidation and conjugation of polyamines, and inhibits shoot formation in tobacco thin layers.
The effect of methyl jasmonate (MJ) on de novo shoot formation and polyamine metabolism was investigated in thin layer explants of tobacco (Nicotiana tabacum L. cv. Samsun). A relatively lowExpand

Pre-harvest polyamine and aminoethoxyvinylglycine (AVG) applications modulate fruit ripening in Stark Red Gold nectarines (Prunus persica L. Batsch)
Putrescine (5, 10 and 20 mM), spermidine (0.5, 1 and 2 mM) and aminoethoxyvinylglycine (AVG; 0.32, 0.64 and 1.28 mM) were applied to peach trees (Prunus persica L. Batsch cv Stark Red Gold) underExpand

Polyamine metabolism is upregulated in response to tobacco mosaic virus in hypersensitive, but not in susceptible, tobacco
• Change is reported in the biosynthetic and oxidative activity of hypersensitive (NN) and susceptible (nn) tobacco (Nicotiana tabacum) plants in response to tobacco mosaic virus (TMV). • MatureExpand

Methylglyoxal(bis-guanylhydrazone) inhibition of organogenesis is not due to S-adenosylmethionine decarboxylase inhibition/polyamine depletion in tobacco thin layers
Previous results indicated that in shoot-forming tobacco thin layers the putative inhibitor of S-adenosylmethionine decarboxylase (SAMDC, EC 4.1.1.21) activity methylglyoxal(bis-guanylhydrazone)Expand

Polyamines and flowering: Spermidine biosynthesis in the different whorls of developing flowers of Nicotiana tabacum L
Abstract The regulation of S‐adenosylmethionine decarboxylase (SAMDC; EC 4.1.1.1), a key enzyme of polyamine biosynthesis, was analysed at the level of transcript accumulation, enzyme activity, andExpand

Polyamine conjugate levels and ethylene biosynthesis: inverse relationship with vegetative bud formation in tobacco thin layers
The effects of two inhibitors of polyamine (spermidine and spermine) biosynthesis, cyclohexylamine (CHA; 5 and 10 mM) and methylglyoxal(bis-guanylhydrazone) (MGBG; 0.1, 0.5 and 1 mM), on theExpand

Secondary metabolism in root and callus cultures of Hyoscyamus muticus L.: the relationship between morphological organisation and response to methyl jasmonate
Production of acid-soluble conjugated di- and polyamines, like that of other secondary metabolites, is enhanced by exposure to methyl jasmonate (MJ). We investigated this metabolic response, andExpand

Polyamine translocation following photoperiodic flowering induction in soybean
Radioactivity translocation after [14C]-spermidine application over the third trifoliate leaf of soybean plants (Glycine max. [L.] Merr, cv. Williams) was checked during the first 72 h of short dayExpand
