Melatonin (ML) is an indolamine that regulates a wide range of physiological processes as growth roots and shoots, antioxidant enzyme activity, seed germination, photosynthetic efficiency promoting stress tolerance in plants, mitigating the harmful effects abiotic stress. Effects pretreatment soybean (Glycine max (L.) Merr.) seeds with 10, 30, 60 90 μM ML were evaluated seedlings under osmotic...

Soybean (Glycine max (Linn.) Merr.) is a widely-cultivated crop, the yield of which markedly affected by adverse environmental conditions. Soil salinization, in particular, has led to degradation agricultural land, resulting poor plant growth and decreased crop yields. In plants, serine/threonine protein kinases (STKs) are involved response variety abiotic stresses. Our previous study identifie...

The aims were to evaluate the suitability of a non-commercial TRIS-lecithin (LC) extender and the effect of different concentrations of catalase (CAT) on motility, capacitation status (Chlortetracycline-assay) and zona pellucida (ZP) binding capacity of canine spermatozoa stored at +5 degrees C for 4 days. The sperm-rich fractions of the ejaculates of four stud dogs were divided into four aliqu...

Thioredoxin (TRX) is a disulfide reductase present ubiquitously in all taxa and plays an important role as a regulator of cellular redox state. Recently, a redox-independent, chaperone function has also been reported for some thioredoxins. We previously identified nodulin-35, the subunit of soybean uricase, as an interacting target of a cytosolic soybean thioredoxin, GmTRX. Here we report the f...

Soybean plant responses to Heterodera glycines (H. glycines) race 3 infection were compared between resistant (Peking, LiaoK89102 and Franklin) and susceptible cultivars (Liao dou 10 and Kaiyu 10) at 10, 17, 20, and 23 days after inoculation (DAI). After inoculation with H. glycines race 3, the isozymes of peroxidase, polyphenol oxidase, superoxide dismutase, and catalase from the soybean roots...

Soybean, the worldwide main source of oil and high protein feeds for the livestock sector has a high cadmium (Cd) accumulation capacity. With this background, the hydroponic culture experiments were conducted to investigate the effects of different concentrations of Cd (0-100 μM) on growth, water relations, photosynthetic variables, oxidative stress, and antioxidant response in two soybean geno...

The mitochondrial malate dehydrogenase-1 (Mdh1) gene of soybean [Glycine max (L.) Merr.] spontaneously mutates to a null phenotype at a relatively high rate. To determine the molecular basis for the instability of the Mdh1 gene, the gene was cloned and sequenced. The null phenotype correlated with the deletion of specific genomic restriction fragments that encode the Mdh1 gene. The composition ...

BACKGROUND AND OBJECTIVES Nephrotic syndrome is a chronic disease especially common in the childhood and adolescence. Reactive oxygen species (ROS) and free radicals have significant role in the pathogenesis of nephrotic syndrome. The aim of this study was to evaluate the effect of soy protein and genistein (main isoflavone of soybean) on renal antioxidant status of nephrotic rats. METHODS Th...

Plant defense response is an elaborate biochemical process shown to depend on the plant genetic background and on the biological stressor. This work evaluated the soybean biochemical foliar response to brown stink bug herbivory injury through an analysis of redox metabolism and proteomic 2DE profiles of susceptible (BRS Silvania RR) and resistant (IAC-100) varieties. The activity of lipoxygenas...

Biotic stress, as a result of plant-pathogen interactions, induces the accumulation of reactive oxygen species in the cells, causing severe oxidative damage to plants and pathogens. To overcome this damage, both the host and pathogen have developed antioxidant systems to quench excess ROS and keep ROS production and scavenging systems under control. Data on ROS-scavenging systems in the necrotr...
