According to the World Health Organization, headache is, nowadays, among most common disorder of nervous system, resulting in serious problems and disability, but it is reasonable to state headache has existed as long as humankind. The purpose
How plants transmit signals through alternate routes during stress conditions? CBL-CIPK mediated calcium signaling
One of the main characteristics of a plant life is sessile nature. Plants counter this frailty by evolving intricate and fast signaling system that can help in transferring stimuli at a very high rate. The phytohormone ABA
Asymmetric cell division is one of the fundamental steps to form the plant body axis. In most flowering plants, the apical-basal axis is established by the asymmetric division of the zygote. In a model plant Arabidopsis thaliana,
Plants are vulnerable to various biotic and abiotic stresses imposed in their respective growth environment. These stresses negatively affect the normal growth, development and productivity. Unlike animals, which can move to conditions conducive for growth and development;
In the last decade, the number of studies isolating and describing extracellular vesicles (EVs) has dramatically grown once their participation in intercellular communication has been confirmed. As transporters of bioactive molecules, EVs can take part in different
Plants utilize long-distance transport systems via their vascular tissues. The xylem is used for water and mineral transport, while the phloem translocates various macromolecules. Although lipids have been detected in the phloem sap, their movement is not
In recent years, research in nanotechnologies has demonstrated that nanometer-sized particles constructed using a wide array of materials (e.g. metals, lipids, polymers, proteins) can offer answers to unmet questions concerning drug/vaccine delivery. Ideally, these systems should prevent
A research group at University Bonn uncovers how plants detect and defeat parasitic worms. Nematodes are a huge threat to agriculture since they parasitize important crops such as wheat, soybean, and banana; but plants can defend themselves.
Plants rely on light as a source of energy. The availability of light is often a limiting factor for the process of photosynthesis. However, too much light can cause cell damage. Plants have numerous mechanisms of adjusting
What is the connection between the ability of the human immune system to destroy invading pathogens, the growth of a pollen tubule on its way to fertilise a flower’s ovum, and the extension of a fungal hypha
Stomata are one of the key evolutionary features responsible for the successful colonization of land by plants. A stoma is a pore surrounded by a pair of guard cells, when these cells are turgid and inflated the
Hormones are small compounds which regulate many aspects of life, from organ development to environmental adaptations. Jasmonates are plant hormones controlling various biological processes including flower development and defense against insects and fungi. In order to conserve
Serving as the building blocks for triacylglycerides and membrane phospholipids, fatty acids are essential in all forms of life. Given their chemical inertness, fatty acids need activation into a more water-soluble form (as acyl-CoA esters), prior to
Constructed wetlands are treatment systems that use natural processes involving wetland vegetation, soils, and their associated microbial assemblages to improve water quality. The Parco Naturale Regionale Molentargius-Saline, located in southern Sardinia between the two cities of Quartu
The prevalence of overweight and obesity is a global concern. Therefore, various weight-loss diets have been developed. A low-carbohydrate weight-loss diet, also known as the Atkins diet, is one such diet. In the United States, the proportion
Does the ethnomedicinal uses of the sour plum tree correlate with its ethnopharmacological properties?
Ximenia caffra Sond. (Fig. 1), commonly referred to as “sour plum” is a common and popular medicinal and fruit tree in the dryland zone in central, eastern and southern Africa. The generic name ‘Ximenia’ commemorates a Spanish
Application of the fungicide kresoxim-methyl prior to drought and salinity stress imposition enhances the ability of plants to survive
Plants are exposed to multiple environmental stresses ( e. g. drought, salinity ), resulting in major yield losses in modern agriculture. Drought and salinity are the two major abiotic threats for plant production and potentially food security.
Offspring of any organism, if they are not clones, differ from each other. Seeds produced by a mother plant are no exception, and they vary in size, color and shape. Usually, these differences are minor and represent
Abiotic stresses such as salinity, drought, flooding, heat, cold, freezing, excess light, UV radiation and heavy metal toxicity have a significant impact on plant growth and crop yield worldwide. Climate change continues to exacerbate the detrimental effects
