Role of inhibitors and biodegradable material in mitigation of nitrogen losses from fertilized lands
Loss of N, occurring mainly through NH3 volatilization, biological denitrification, and NO3- leaching, has both economic and environmental implications. Therefore, the economic benefits of reduced environmental pollution and future damage to our environment as a result of the use of urease inhibitors are of higher significance to the production of gains over the long-term. The literature review discussed the role,...

Maize breeding for marginal lands: Physiological and molecular approach to decipher response and selection of maize recombinant inbred lines (RILs) under water deficit at early growth stage
Drought is the major abiotic stress constraining the production of maize (Zea maysL.) in the arid and semi-arid areas. Recombinant inbred lines (RILs) with improved performance from the 6th selection cycles were evaluated against drought stress at early growth stages and genetic distance was determined through random amplified polymorphic DNA (RAPD) primers. Significant variation was observed in the rate of water loss...

Bioinformatics Analysis of Envelope Glycoprotein E epitopes of Dengue Virus Type 3
The E glycoprotein of dengue virus is responsible for the viral binding to the receptor. The crystal structure of envelope glycoprotein has already been determined. However, where the well-defined B-cell and T-cell epitopes are located is still a question. Because of the large variations among the four dengue genotypes, it is very hard to design conserved epitopes for all of them. Therefore, we selected only one...

Symbiotic effectiveness of pea-rhizobia associations and the implications for farming systems in the western Loess Plateau, China
Interactions between pea (Pisum sativa L.) cultivars and Rhizobium strain affect the symbiotic relationship and ultimately both the nitrogen fixing capacity and the yield. Since Pisum sativum L. is poorly nodulated in the Loess Plateau of China where this crop is grown, the response of pea cultivars Yannong No.2 and Luwan to inoculation with reference Rhizobium ACCC16101, ACCC16103 and...

Effect of drought at the post-anthesis stage on remobilization of carbon reserves in two wheat cultivars differing in senescence properties
Remobilization and transfer of stored food in vegetative tissues to the grains in monocarpic plants require the initiation of whole plant senescence. However, mechanism by which plant senescence promotes remobilization of assimilates that are rather obscure. This study examined the relationship between the senescence induced by water deficits and C remobilization during grain filling. Two wheat cultivars (Triticum...

Quantitative trait loci (QTL) mapping for inflorescence length traits in Lablab purpureus (L.) sweet
Lablab purpureus (L.) sweet is an ancient legume species whose immature pods serve as a vegetable in south and south-east Asia. The objective of this study is to identify quantitative trait loci (QTLs) associated with quantitative traits such as inflorescence length, peduncle length from branch to axil, peduncle length from axil to lowermost flowering node, rachis length, node number of inflorescence,...

Plant regeneration of Senecio hypochionaeus var. argaeus
Senecio genus includes taxa that can be used for agricultural, pharmacological, physiological and biochemical studies, on account of their different pyrrolizidine alkaloids (PAs). Senecio hypochionaeus var. argaeus is an endemic species in Turkey. Successful callus production was achieved in all the N6-benzyladenine (BA) and naphthaleneacetic acid (NAA) experiments in the root explants. The highest level of shoot...

Reactions of selected eggplant cultivars and lines to verticillium wilt caused by Verticillium dahliae Kleb.
Verticillium wilt caused by the fungus Verticillium dahliae Kleb. leads to decrease in the yield and quality of eggplant, an economically important vegetable in Turkey. To develop eggplant lines that are resistant to or tolerant to verticillium wilt, this study used cultivars K-1, K-2, K-3, K-4, K-5, K-6, K-7 and K-8 in the studies presented here. The wild species Solanum torvum and Solanum...

The impact of dust emits by the steel complex of El Hadjar (ANNABA) on two biological models: Mousses and lichens
The effect of the dust rejected by the steel complex of El Hadjar (SIDER) studies was by subjecting the mousses and lichens under a treatment by various concentrations of dust. Previously, the chemical composition of this dust was to analyze and show as well the quantitative and qualitative composition of dust and the dust is consisted of the pollutants with rates much higher than those authorized by WHO. All the...

Degradation of feather and hair by Chrysosporium tropicum: A potent keratinophilic fungus
The current study was aimed at the degradation of feather and hair wastes in an eco-friendly way, which should further be helpful to make the waste dumping soils fertile. Degradation of feathers and hair was assessed by a highly potent keratinophilic fungi namely Chrysosporium tropicum. The 60 day experiment was set up with sterile defatted feather and hair as substrates in a mineral medium along with the inoculum...

Effect of metal poisoning and the implications of gender and age on the elemental composition in patients with mental behavioural disorders
The objective of this work was to investigate the possible correlation between the exposure to selected toxic metals and the behavioural disorder of mentally ill patients. The study also sought to establish if gender and age of the patient had an effect on the pattern of the elemental distribution in their head hair and blood samples. To achieve this, the concentrations of a number of selected toxic metal elements were...

Optimization of medium composition for apple rootstocks
Impact of medium composition (plant growth regulators, mineral nutrients) on multiplication rate, shoot elongation, callusing and rooting of apple rootstocks ('M9', 'M27', and 'MM106') cultured on gelled basal Murashige and Skoog (MS) medium were investigated. Multiplication rate was mainly dependent upon kind of plant growth regulators especially, 6-benzylaminopurine (BA),...

Hairs as biomonitors of hazardous metals present in a work environment
Human beings come across metal exposure not only through contaminated water and food, but through their metal body burden which increases by working in the environment that is contaminated and not safe. These hazardous metals present in the workplace increases the risk of both illness and injury. Illness tends to develop over time following repeated exposure to a hazard, whereas injury usually occurs instantly. Human...

Computational analysis of human miRNAs phylogenetics
Over one third of the human genome appears to be regulated by miRNAs which are involved in fundamental cellular processes and are negative regulators of gene expression. MicroRNAs (miRNAs) are evolutionary conserved across broad phylogenetic distances and have gained considerable attention about evolution, genetic and phylogenetic analysis. Comparing sequences of miRNA precursors within a species and between closely...
