We examined ameliorative effects of salicylic acid (SA) on two cadmium (Cd)-stressed legume crops with different Cd tolerances, viz. Phaseolus aureus (Cd sensitive) and Vicia sativa (Cd tolerant). Cd at 50 μM significantly increased the production of hydrogen peroxide (H2O2) and superoxide anion (O 2 ·− ) in root apoplasts of P. aureus and V. sativa. When(More)
The effects of cadmium (Cd) on the accumulation of hydrogen peroxide (H(2)O(2)) and superoxide anion (O(2)(-)) in leaves of Phaseolus aureus and Vicia sativa were investigated. Cadmium at 100 microM significantly increased the production of O(2)(-) and H(2)O(2), as well as the activities of plasma membrane-bound nicotinamide adenine dinucleotide phosphate(More)
Copper (Cu) is an essential micronutrient required for growth and development of plants. However, excess Cu is toxic to plants. To understand the mechanisms involved in copper stress response, a proteomic approach was used to investigate the differences in Cu stress-induced protein expression between a Cu-tolerant variety (B1139) and a Cu-sensitive one(More)
The effects of excess copper (Cu) on the accumulation of hydrogen peroxide (H2O2) and antioxidant enzyme activities in roots of the Cu accumulator Elsholtzia haichowensis Sun were investigated. Copper at 100 and 300 μM significantly increased the concentrations of malondialdehyde and H2O2, and the activities of catalase (E.C., ascorbate peroxidase(More)
Expansins are proteins that are the key regulators of wall extension during plant growth. To investigate the role of TaEXPB23, a wheat expansin gene, we analyzed TaEXPB23 mRNA expression levels in response to water stress in wheat and examined the drought resistance of transgenic tobaccos over-expressing TaEXPB23. We found that the expression of TaEXPB23(More)
Improvements in the serological diagnosis of neosporosis are needed to differentiate acute versus chronic Neospora caninum infections. In the present study, N. caninum microneme protein 10 (NcMIC10), similar to other microneme proteins, was shown to be released in a calcium-dependent manner. NcMIC10 may be discharged during active invasion of host cells by(More)
The effects of excess copper (Cu) on the production of reactive oxygen species (ROS) and antioxidant enzyme activities in leaves of the Cu-accumulator Elsholtzia haichowensis Sun were investigated. The addition of 100 microM of copper significantly increased the accumulation of hydrogen peroxide (H(2)O(2)) and the activities of superoxide dismutase (SOD)(More)
In addition to many other genes, tissue-specific genes (TSGs) represent a set of genes of great importance for human physiology. However, the links among TSGs, diseases, and potential therapeutic agents are often missing, hidden, or too scattered to find. There is a need to establish a knowledgebase for researchers to share this and additional information(More)
Porcine epidemic diarrhea virus (PEDV) and porcine deltacoronavirus (PdCV) cause indistinguishable clinical signs and pathological changes in swine. Here we investigated the antigenic relationship between PEDV and PdCV. We provide the first evidence that conserved epitope(s) on the respective viral nucleocapsid proteins cross-react with each other although(More)
EhMT1, a type 1 metallothionein (MT) gene, was cloned from Elsholtzia haichowensis, a Cu-tolerant plant. Typical of plant type 1 MTs, EhMT1 encodes a putative peptide of 74 amino acid residues containing cysteine-rich domains. Sequence comparisons with various databases revealed strong similarities at the nucleotide and amino acid levels between EhMT1 and(More)
