Blumeria graminis f.sp. tritici (Bgt) infection greatly interferes with the normal source-sink relationships and always causes tremendous loss of yield and quality in wheat. To better understand the impact of this pathogen on grain development, proteome characterization during grain development in susceptible wheat cultivar Xinong 979 infected by powdery mildew was investigated by 2-DE and tandem MALDI-TOF/TOF-MS. Identification of 111 differentially expressed protein spots representing 85 unique proteins and six expression patterns showed a chronological description of wheat grain formation...

Baker's asthma is a serious airway disease triggered by wheat proteins CM3 α-amylase/trypsin inhibitor. The purpose of the present study was to investigate the impact of genotype and crop year on allergen CM3 α-amylase/trypsin inhibitor associated to baker's asthma. A historical series of Tunisian durum wheat (100 accessions), derived from three crop years, was used to compare the amount of CM3 from landraces to advanced cultivars. CM3 protein quantification was assessed after an enzymatic cleavage of the soluble protein extracts on an UPLC/ESI-MS system, using a marker peptide for its quantification...

Scenario analysis constitutes a useful approach to synthesize knowledge and derive hypotheses in the case of complex systems which are documented with mainly qualitative or very diverse information. In this article, a framework for scenario analysis is designed and then, applied to global wheat health within a timeframe from today to 2050. Scenario analysis entails the choice of settings, the definition of scenarios of change, and the analysis of outcomes of these scenarios in the chosen settings. Three idealized agrosystems, representing a large fraction of the global diversity of wheat-based agrosystems, are considered, which represent the settings of the analysis...

In the North China Plain, groundwater tables have been dropping at unsustainable rates of 1 m per year due to irrigation of a double cropping system of winter wheat and summer maize. To reverse the trend, we examined whether alternative crop rotations could save water. Moisture contents were measured weekly at 20 cm intervals in the top 180 cm of soil as part of a 12-year field experiment with four crop rotations: sweet potato→ cotton→ sweet potato→ winter wheat-summer maize (SpCSpWS, 4-year cycle); peanuts → winter wheat-summer maize (PWS, 2-year cycle); ryegrass-cotton→ peanuts→ winter wheat-summer maize (RCPWS, 3-year cycle); and winter wheat-summer maize (WS, each year)...

Arbuscular mycorrhiza (AM) can help plants to tolerate arsenic (As) toxicity. However, plant responses are found to vary with the host plant and the AM fungal species. The present study compares the efficacy of two AM fungi Rhizoglomus intraradices (M1) and Glomus etunicatum (M2) in amelioration of As stress in wheat (Triticum aestivum L. var. HD-2967). Mycorrhizal (M) and non-mycorrhizal (NM) wheat plants were subjected to four levels of As (0, 25, 50, and 100 mg As kg(-1) soil). Although As additions had variable effects on the percentage of root colonized by the two fungal inoculants, each mycobiont conferred benefits to the host plant...

Acidic soils are distributed worldwide, predominantly in tropical and subtropical areas, reaching around 50% of the arable soil. This type of soil strongly reduces crop production, mainly because of the presence of aluminum, which has its solubility increased at low pH levels. A well-known physiological mechanism used by plants to cope with Al stress involves activation of membrane transporters responsible for organic acid anions secretion from the root apex to the rhizosphere, which chelate Al, preventing its absorption by roots...

Polycyclic aromatic hydrocarbons (PAHs) accumulated in agricultural soils are likely to threaten human health and ecosystem though the food chain, therefore, it is worth to pay more attention to soil contamination by PAHs. In this study, the presence, distribution and risk assessment of 16 priority PAHs in rice-wheat continuous cropping soils close to industrial parks of Suzhou were firstly investigated. The concentrations of the total PAHs ranged from 125.99 ng/g to 796.65 ng/g with an average of 352.94 ng/g...

The ventral lateral geniculate nucleus (LGNv) is a retinorecipient part of the ventral thalamus and in cats, it consists of medial (M), medial intermediate (IM), lateral intermediate (IL), lateral (L), and dorsal (D) subdivisions. These subdivisions can be differentiated not only by their cytoarchitecture, but also by their connectivity and putative functions. The LGNv may play a role in visuomotor gating, in that there is evidence of cerebellar afferent projections to the intermediate subdivisions. The cerebellar posterior interpositus (IP) and lateral (LC) nuclei are known to project to IM and IL, but the specifics of these projections are unclear...

Dasypyrum villosum is a valuable genetic resource for wheat improvement. With the aim to efficiently monitor the D. villosum chromatin introduced into common wheat, two novel retrotransposon sequences were isolated by RAPD, and were successfully converted to D. villosum-specific SCAR markers. In addition, we constructed a chromosomal karyotype of D. villosum. Our results revealed that different accessions of D. villosum showed slightly different signal patterns, indicating that distribution of repeats did not diverge significantly among D...

BACKGROUND: Currently, there is an epidemic expansion of the obesity rates worldwide. The increasing number of obese individuals associated with the aging of population leads to increasing number of individuals with type 2 diabetes mellitus (T2DM) at the same rate. The traditional factors that link obesity to T2DM are related to genetics, hypercaloric diet, sedentary lifestyle, and stress. Individuals from lower socioeconomic status (SES) have restricted autonomy and opportunities that could lead to more stress and consequently increase in stress hormones, such as cortisol, catecholamines, glucagon, and growth hormone, which might ultimately change fat deposition, increasing visceral fat and increasing the risk of T2DM mellitus development...

Longshoremen are exposed to large amounts of grain dust while loading of grain into the holds of vessels. Grain dust inhalation has been linked to respiratory diseases such as chronic bronchitis, hypersensitivity, pneumonitis, and toxic pneumonitis. Our objective was to characterize the exposure of longshoremen to inhalable and total dust, endotoxins, and cultivable bacteria and fungi during the loading of grain in a vessel's hold at the Port of Montreal in order to assess the potential health risks. Sampling campaigns were conducted during the loading of two different types of grain (wheat and corn)...

The aim of this work was to compare the traditional with a non-conventional (i.e. kernel micronisation) durum wheat milling process by monitoring the content of bound, conjugated and free phenolic acids (PAs) and the level of the total antioxidant capacity (TAC) occurring in the durum wheat pasta production chain, from seed to cooked pasta. The traditional transformation processes negatively influenced TAC and PA content (40% and 89% decrease from seed to cooked pasta, respectively), mainly during the milling process (25% and 84% decrease of TAC and PA, respectively), which has been related to the removal of external layers of kernels...

A novel peptide was extracted from wheat germ globulin and purified using ion-exchange chromatography, gel filtration chromatography and semi-preparative reverse phase-high performance liquid chromatography (RP-HPLC). The sequence of the peptide was found to be Glu-Cys-Phe-Ser-Thr-Ala (ECFSTA). Its immunomodulatory effects were evaluated, and the results showed that ECFSTA could enhance phagocytosis of RAW 264.7 cells and significantly increase their secretion of nitric oxide (NO), interleukins-6 (IL-6), tumor necrosis factors-α (TNF-α), and reactive oxygen species (ROS)...

Wheat was introduced to China approximately 4500 years ago, where it adapted over a span of time to various environments in agro-ecological growing zones. We investigated 717 Chinese and 14 Iranian/Turkish geographically diverse, locally adapted wheat landraces with 27,933 DArTseq (for 717 landraces) and 312,831 Wheat660K (for a subset of 285 landraces) markers. This study highlights the adaptive evolutionary history of wheat cultivation in China. Environmental stresses and independent selection efforts have resulted in considerable genome-wide divergence at the population level in Chinese wheat landraces...
