Effects of nickel toxicity on expression of genes associated with nickel resistance in white spruce (Picea glauca): Nickel translocation in plant tissues.
… a) nickel accumulation and translocation within tissues and b) nickel effects on gene expression in white spruce (Picea glauca). The results of the study revealed that even at the highest dose of 1,600 mg of Ni /kg of soil, there was no physical evidence of toxicity to P. glauca seedlings …

Quantitative analysis of co-enzyme a in a plant tissues and cancer biomarkers in urine samples by using capillary electrophoresis and liquid chromatography-mass spectrometry
<p>"Despite continuous effort and progress in cancer detection and therapy, cancer remains one of our greatest health concerns because of its low survival rate and rapid incidence increase. One reason for this is the late detection and therefore pre-cancer diagnosis is crucial. In pre-cancer …

Ecological Distinctions in Diet, Food Toughness, and Masticatory Anatomy in a Community of Six Neotropical Primates in Guyana, South America
I examine the toughness of plant tissues (N = 14) handled and dentally processed by these primates. General dietary categories (e.g. fruits and leaves) provide only limited insights into the dietary patterns of the study species. However, analyses of opened and masticated plant tissues reveals …

The effect of copper stress on inter-trophic relationships in a model tri-trophic food chain.
… on the toxic and adaptive responses of wheat plants to copper-induced stress were conducted to establish the effects of different levels of Cu (0 – 200 mg kg -1) on growth, nutrient levels and the total plant proteins of wheat seedlings (Triticum aestivum) using pot experiments. A tri-trophic …

Phytoremediation of Sembrong River waters using neptunia oleracea and pistia stratiotes
… as well as the effect on the two plant species (Neptunia oleracea and Pistia stratiotes) due to bio mineralization of heavy metals. Water quality parameters measured were conductivity, turbidity, pH, Dissolved Oxygen (DO), Biological Oxygen Demand (BOD), Chemical Oxygen Demand …

Oxalic acid production by the ectomycorrhizal fungus Hebeloma westraliensis and its role in the nutrient acquisition and growth of Eucalyptus diversicolor in calcareous soil
… enhancement of the mineral nutrition of host plants. Particular attention was paid to the role of mycorrhizae in acquiring P from inorganic phosphates. Two experiments were designed to study a mechanism by which the ectomycorrhizal fungus Hebeloma westraliensis can enhance the availability and …

Biochemical and Functional Characterization of Induced Terpene Formation in Arabidopsis Roots
Plants have evolved a variety of constitutive and induced chemical defense mechanisms against biotic stress. Emission of volatile compounds from plants facilitates interactions with both beneficial and pathogenic organisms. However, knowledge of the chemical defense in roots is still limited. In …

Effects of Land Disposal of Pulp Mill Effluents on Plant Nutrient Uptake and Element Balance
<p>An analysis of the soil and plant tissues was undertaken to ascertain the effect that land irrigation with pulp mill effluent has on nutrient uptake and element balance of tree seedlings. Results show that the effluent significantly increased the sodium content of both soil and tissue; however, …

Method development for mass spectrometric characterization of ultra-small nanomolecules and mass spectrometry imaging of selected biomolecules
… samples such as microbial colonies, animal tissues, plant tissues and forensic samples. The microbial species produced important natural products and metabolites which can be applicable in different fields. This chapter has two themes based on method development for MSI to detect the …

Fabrication and osmosis-mediated dynamics of a plant-inspired, fluid-filled, soft actuator
Non-vascular plant tissues constitute a special class of poroelastic solids where closed cells encapsulate the fluid. The fluid can diffuse through the semi-permeable cell walls, thereby changing the cell volume, stretching the cell wall, and consequently changing the hydrostatic pressure in the …

Transgenic Plants, Current State, and Influence on the Environment
The techniques of plant transformation are discussed. They are bacterial-mediated, electroporation transformation, biolistic (particle bombardment), and microbeam laser. By using different strategies, foreign gene(s) from various organisms can be inserted into plant genome and expressed. …

Multiscale Modelling and Analysis of Plant Cell Signalling Processes and Biomechanics
Plant growth, development, and responses to environmental cues are regulated by complex networks of interacting signalling molecules. Signalling pathways activate in response to external or internal cues, leading to a series of signalling processes which end with changes in gene expression. By …
