Polyamines - The Principal Candidate Substance of Soybean-Induced Health
In countries with sufficient medical and public health resources, cardiovascular diseases (CVDs), cancers, and other chronic metabolic diseases are major killers. The incidence of these diseases increases with aging and, therefore, they are called age-associated diseases. Importantly, the rate of mortality from these diseases ranges widely, even in countries with similar social and economic con...
متن کاملLevels of polyamines and kinetic characterization of their uptake in the soybean pathogen Phytophthora sojae.
Polyamines are ubiquitous biologically active aliphatic cations that are at least transiently available in the soil from decaying organic matter. Our objectives in this study were to characterize polyamine uptake kinetics in Phytophthora sojae zoospores and to quantify endogenous polyamines in hyphae, zoospores, and soybean roots. Zoospores contained 10 times more free putrescine than spermidin...
متن کاملInvolvement of exogenous polyamines enhances regeneration and Agrobacterium-mediated genetic transformation in half-seeds of soybean
The present work demonstrates the participation of polyamines (PAs) to improve direct regeneration and Agrobacterium-mediated transformation in soybean half-seeds. The inclusion of PAs to culture medium along with optimal plant growth regulators (PGRs) enhanced shoot induction [98.3 %; 4.44 µM N6-benzyladenine (BA) and 103.27 µM spermidine] and elongation [90.0 %; 1.45 µM gibberellic acid (GA3)...
متن کاملPolyamines Play a Positive Role in Salt Tolerant Mechanisms by Activating Antioxidant Enzymes in Roots of Vegetable Soybean
Two cultivars contrasting in NaCl tolerance were used to investigate the possible involvement of polyamines in salt tolerant mechanisms in roots of vegetable soybean. ‘Tianfeng’, the salt tolerant cultivar exhibited overall higher contents of free, soluble conjugated and insoluble bound forms of polyamines (putrescine, spermidine and spermine) except for free spermidine over the salt sensitive ...
متن کاملPolyamines and prostatic cancer.
The importance of polyamines in prostatic growth and differentiation has prompted studies to evaluate the clinical relevance of the ornithine decarboxylase/polyamine system in prostatic cancer. These studies show that differences in biological behaviour of prostatic (cancer) cells are associated with changes in polyamine levels and/or the activity of their metabolic enzymes. Faulty antizyme reg...
