In plants, different forms of nitrogen (NO3- or NH4+) affect nutrient uptake and environmental stress responses. In the present study, we tested whether NO3- and NH4+ affect the ability of rice (Oryza sativa) to tolerate the toxic heavy metal cadmium (Cd). Compared with NO3-, NH4+ treatment

Putrescine alleviates aluminum toxicity in rice (Oryza sativa) by reducing cell wall Al contents in an ethylene-dependent manner.

Aluminum (Al³⁺ ) toxicity in acidic soils limits crop productivity worldwide. In this study, we found that putrescine (PUT) significantly alleviates Al toxicity in rice roots. The addition of 0.1 mM PUT promoted root elongation and reduced the Al content in the root apices of Nipponbare

Growth Inhibition in Suspension-Cultured Rice Cells under Phosphate Deprivation Is Mediated through Putrescine Accumulation.

The effects of phosphate deprivation on the growth and polyamine levels of suspension-cultured rice (Oryza sativa) cells were investigated. When rice suspension cells were deprived of phosphate, cell growth was markedly inhibited. Phosphate deprivation resulted in a higher putrescine level and lower

Polyamine oxidase 7 is a terminal catabolism-type enzyme in Oryza sativa and is specifically expressed in anthers.

Polyamine oxidase (PAO), which requires FAD as a cofactor, functions in polyamine catabolism. Plant PAOs are classified into two groups based on their reaction modes. The terminal catabolism (TC) reaction always produces 1,3-diaminopropane (DAP), H2O2, and the respective aldehydes, while the

Effects of ethylene on free polyamine biosynthesis in rice (Oryza sativa L. cv Taichung Native 1) coleoptiles were investigated in sealed and aerobic conditions. In sealed conditions, putrescine increased significantly and coincided with ethylene accumulation. Application of ethylene in sealed

Reduction in the endogenous arginine decarboxylase transcript levels in rice leads to depletion of the putrescine and spermidine pools with no concomitant changes in the expression of downstream genes in the polyamine biosynthetic pathway.

We investigated whether down-regulation of arginine decarboxylase (ADC) activity and concomitant changes in polyamine levels result in changes in the expression of downstream genes in the polyamine pathway. We generated transgenic rice (Oryza sativa L.) plants in which the rice adc gene was

Increased polyamine biosynthesis enhances stress tolerance by preventing the accumulation of reactive oxygen species: T-DNA mutational analysis of Oryza sativa lysine decarboxylase-like protein 1.

A highly oxidative stress-tolerant japonica rice line was isolated by T-DNA insertion mutation followed by screening in the presence of 50 mM H(2)O(2). The T-DNA insertion was mapped to locus Os09g0547500, the gene product of which was annotated as lysine decarboxylase-like protein (GenBank

Putrescine differently influences the effect of salt stress on polyamine metabolism and ethylene synthesis in rice cultivars differing in salt resistance.

Effects of salt stress on polyamine metabolism and ethylene production were examined in two rice (Oryza sativa L.) cultivars [I Kong Pao (IKP), salt sensitive; and Pokkali, salt resistant] grown for 5 d and 12 d in nutrient solution in the presence or absence of putrescine (1 mM) and 0, 50, and 100

CONCLUSIONS Oryza sativa polyamine oxidase 1 back-converts spermine (or thermospermine) to spermidine. Considering the previous work, major path of polyamine catabolism in rice plant is suggestive to be back-conversion but not terminal catabolism. Rice (Oryza sativa) contains seven genes encoding

The results showed that the activities of Agrinine decarboxylase(ADC), Ornithine decarboxylase(ODC) and s-Adenosylmethionine decarboxylase(SAMDC) were increased by 165.74%, 104.60% and 89.60% in the leaves of Shan You63(Sy63) and by 59.91%, 41.30% and 23.68% in the leaves of Nancheum(NC). Only ADC

We have shown (S. Bajaj and M.V. Rajam [1995] Plant Cell Rep 14: 717-720) that a significant reduction in morphogenetic potential occurs in callus cultures of rice (Oryza sativa L. cv TN-1) (up to 1 year old), and that plant regeneration could be improved in such cultures with spermidine treatment.

Submergence and treatment with ethylene or gibberellic acid (GA3) stimulates rapid growth in internodes of deepwater rice (Oryza sativa L. cv. "Habiganj Aman II"). This growth is based on greatly enhanced rate of cell-division activity in the intercalary meristem (IM) and on increased cell

Aminopropyl transferases like spermidine synthase (SPDS; EC 2.5.1.16), spermine synthase and thermospermine synthase (SPMS, tSPMS; EC 2.5.1.22) belong to a class of widely distributed enzymes that use decarboxylated S-adenosylmethionine as an aminopropyl donor and putrescine or spermidine as an

Putrescine is a member of a group of aliphatic compounds, known as polyamines, which are derived from the breakdown of amino acids in living (and dead) cells. Along with the grimly named cadaverine, putrescine was discovered in 1885 by the German physician Ludwig Brieger, who identified these

Incubation of 3-d-old seedlings of Oryza sativa L. cv Arborio under anaerobic conditions, leads to a large increase in the titer of free putrescine while aerobic incubation causes a slight decrease. After 2 days, the putrescine level is about 2.5 times greater without oxygen than in air. The rice
