Aluminum (Al) is the most abundant metal in the earth's crust, but its availability depends on soil pH. Despite this abundance, Al is not considered an essential element and so far no experimental evidence has been put forward for a biological role. In plants and other organisms, Al can have a beneficial or toxic effect, depending on factors such as, metal concentration, the chemical form of Al, growth conditions and plant species. Here we review recent advances in the study of Al in plants at physiological, biochemical and molecular levels, focusing mainly on the beneficial effect of Al in plants (stimulation of root growth, increased nutrient uptake, the increase in enzyme activity, and others). In addition, we discuss the possible mechanisms involved in improving the growth of plants cultivated in soils with acid pH, as well as mechanisms of tolerance to the toxic effect of Al.

Terrestrial vegetation is a key component of the Earth system, regulating the exchange of carbon, water, and energy between land and atmosphere. Vegetation affects soil moisture dynamics by absorbing and transpiring soil water, thus modulating land-atmosphere interactions. Moreover, changes in vegetation structure (e.

Aim: This research concerns the patentability of carvacrol; it could be helpful for researchers to easily identify any innovation in the biotechnological application of this monoterpene as well as other similar compounds.
Background: Like thyme or oregano, several plants in the Lamiaceae family produce carvacrol. It is one of the secondary metabolites with several biological activities, including the improvement in plants' resistance and their protection.
Effect of Extraction Methods and Preheat Treatments on the Functional Properties of Pumpkin Seed Protein Concentrate.

This study explores the effect of different extraction methods and preheat treatments in obtaining protein concentrate from pumpkin seed flour. The effects on the yield and functional properties of pumpkin seed protein concentrate (PSPC) were compared alongside microwave and conventional preheating methods using alkali, salt, and enzyme-assisted alkali extraction techniques. Analytical assessments included proximate analysis, soluble protein content, water solubility index (WSI), emulsification activity (EA) and stability (ES), foaming capacity (FC) and stability (FS), and antioxidant activity (AA).

A world apart from academic research, the path from developing a polyphenol-rich crop to a product available to consumers is not one taken by many research scientists. Here we review the steps taken to commercialize anthocyanin-enriched purple tomatoes in the USA. In describing some of the difficulties encountered and the work that was necessary for a successful commercial launch of a new biotech product, we hope to encourage others to believe that there is a viable route to market, and an appetite for polyphenol-enriched foods that can protect health.

Unlabelled: The redox conditions in the littoral limnic sediments may be affected by the penetration of plant roots which provide channels for oxygen transport into the sediment while decomposition of the dead roots results in consumption of oxygen. The goal of this work was to study the impact of environmental parameters including penetration of roots of L. into the sediments on cycling of the redox-sensitive elements in Lake Kinneret.
