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
For humans to become a multi-planetary species, we must first overcome many technological and biological hurdles. The closest two potential sites for extraterrestrial colonization (apart from low Earth orbit) are the Moon and Mars. The Moon exhibits
Low temperature is a determinative environmental factor, which can affect all aspects of plant life and determine their geographical distribution and productivity. According to the response to low temperatures plants are divided into some groups: frost- resistant,
A domestic central heating system uses a boiler, powered by electric or gas, to heat water. This is then pumped around the system to radiators that heat a room by radiation and convection. The heat transfer fluid
Plants rely on roots for their supply of nutrients and water but not all roots are the same. Typically when asked to picture a plant root system we might think of the tap root with ‘lateral’ roots
Many organisms have circadian clocks. These internal clocks play essential roles for predicting day-length or seasons, and they regulate behavior and hormonal secretion in animals, and also regulating flowering time and cell elongation in plants. In animals,
The main goal of obligatory viral parasites is to create the perfect environment for its multiplication. Therefore, the first step is to avoid degradation by the host cellular degradation. Tomato yellow leaf curl virus (TYLCV) is not
More than 70% of the world’s human population lives in the coastal environments and in recent years, population growth and related human activities (agriculture, wastewater treatment plans, urban runoff) have increased nutrient inputs (inorganic fertilizing compounds) in
Engineered nanoparticles (ENPs) (intentionally created particles with one or more dimensions greater than 1 nanometer and less than 100 nanometers) are now used in consumer and industrial products. However, there are concerns surrounding their potential effects on
Waste management is a source of airborne microorganisms and their associated compounds (bioaerosols) in the waste facilities’ air. Bioaerosol exposure can lead to several pathologies, hence additional monitoring should be performed to evaluate the effectiveness of implemented
Phosphorus (P) is an essential nutrient for the growth and development of plants. Its limited availability due to the low solubility, often limits crop production. Therefore, soluble phosphate fertilizers are commonly applied to achieve maximum crop productivity.
