putrescine Plays a Positive Role in Salt-Tolerance Mechanisms by Reducing Oxidative Damage in Roots of Vegetable Soybean

引用

Journal of Integrative Agriculture 2014年第2期13卷 349-357页

作者： ZHANG Gu-wen XU Sheng-chun HU Qi-zan MAO Wei-hua GONG Ya-ming Institute of Vegetable Zhejiang Academy of Agricultural Sciences Center of Analysis and Measurement Zhejiang University

Polyamines play important roles in plant tolerance to environmental stress. With the aim of investigating the possible involvement of putrescine （Put） in salt-tolerance mechanisms in vegetable soybean roots, exogenous Put （10 mmol L＂） and its biosynthetic inhibitor D-arginine （D-Arg）（0.5 mmol L-1） were added to nutrient solution when vegetable soybean （Glycine max L. cv. Huning 95-1） seedlings were exposed to 100 mmol L^-11 sodium chloride （NaCl）. The results showed that Put ameliorated but D-Arg aggravated the detrimental effects of NaCl on plant growth and biomass production. Under NaCl stress, levels of free, soluble conjugated and insoluble bound types of Put in roots of vegetable soybean were reduced, whereas those of free, soluble conjugated, and insoluble bound types of spermidine （Spd） and spermine （Spm） were increased. Exogenous Put eliminated the decrease in Put but promoted the increase of Spd and Spm. However, these changes could be reversed by D-Arg. Under NaCl stress, activities of arginine decarboxylase （ADC）, S-adenosylmethionine decarboxylase （SAMDC）, diamine oxidase （DAO）, and polyamine oxidase （PAO） were induced, with exogenous Put promoting and D-Arg reversing these changes. Furthermore, NaCl stress decreased activities of antioxidant enzymes. Exogenous Put alleviated but D-Arg exaggerated these effects of NaCl stress, resulting in the same changes in membrane damage and reactive oxygen species （ROS） production. These results indicated that Put plays a positive role in vegetable soybean roots by activating antioxidant enzymes and thereby attenuating oxidative damage.

putrescine mitigates intestinal atrophy through suppressing inflammatory response in weanling piglets

Journal of Animal Science and Biotechnology 2019年第4期10卷 1067-1080页

Background: Polyamines are essential for cell growth and beneficial for intestinal maturation. To evaluate the effects of putrescine on alleviating intestinal atrophy and underlying molecular mechanisms, both in vivo feeding trial and in vitro cell culture were conducted. Weanling pigs were fed a diet supplemented with 0, 0.1%, 0.2% or0.3% putrescine dihydrochloride, whereas porcine intestinal epithelial cells(IPEC-J2) were challenged with lipopolysaccharide(LPS) in the presence of 200 μmol/L ***: Dietary supplementation with 0.2% putrescine dihydrochloride decreased the incidence of diarrhea with an improvement in intestinal integrity. Inhibition of ornithine decarboxylase activity decreased the proliferation and migration of IPEC-J2 cells, and this effect was alleviated by the supplementation with putrescine. The phosphorylation of extracellular signal regulated kinase and focal adhesion kinase was enhanced by putrescine. LPS increased the expression of inflammatory cytokines [tumor necrosis factor α(TNF-α), interleukin 6(IL-6) and IL-8],and inhibited cell proliferation and migration in IPEC-J2 cells. Adding exogenous putrescine suppressed the expression of TNF-α, IL-6 and IL-8, and recovered cell migration and proliferation in LPS-treated IPEC-J2 cells. Dietary putrescine supplementation also reduced the m RNA levels of TNF-α, IL-6 and IL-8 and their upstream regulator nuclear receptor kappa B p65 subunit in the jejunal mucosa of ***: Dietary supplementation with putrescine mitigated mucosal atrophy in weanling piglets through improving anti-inflammatory function and suppressing inflammatory response. Our results have important implications for nutritional management of intestinal integrity and health in weanling piglets and other neonates.

American Journal of Plant Sciences 2013年第2期4卷 297-301页

作者： Vineeta Awasthi Indreshu Kumar Gautam Rakesh Singh Sengar Sanjay Kumar Garg Department of Plant Science M.J.P. Rohilkhand University Bareilly India Sardar Vallabh Bhai Patel University of Agriculture and Technology Meerut India

The effect of different concentrations of putrescine on biochemical changes in root and shoot of six days old maize seedlings in terms of enzymes of ammonium assimilation were examined. The results revealed that glutamate dehydrogenase (GDH) activity was enhanced at lower concentration of putrescine but at higher concentration, the activity of this enzyme was declined. Glutamine synthetase (GS) activity decreased with increase in concentration of putrescine and it was highest at 1000 μm concentration. Howe ver, glutamate synthase (GOGAT) activity increased with increase in concentration of putrescine upto 100 μm in root and upto 50 μm in shoot and further increase in concentration resulted in decline of enzymatic activity. Protein and total nitrogen content increased upto 10 μm concentration of putrescine and it decreased further with increase in concentration both in root and shoot of maize seedling.
