In vivo dissection of extracellular vesicles production in plants

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

Arabidopsis ACYL-COA-BINDING PROTEIN6: a lipid-binding protein in the phloem

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

Getting health allies from agriculture enemies

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

Deciphering plant immunity against parasites

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.

Chloroplast movements after blue light pulses give new insights into the photoreceptor functioning

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

NOXs, generators of electrochemical energy to drive ion fluxes in humans plants and fungi

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

Early land plants evolved a simple but effective mechanism to place stomata away from each other

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

Landscapes of jasmonates during flower development and leaf stresses

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

Acyl-CoA-binding proteins help plants “degrease” adversities

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

Challenging nature conservation in a peri-urban area

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

Bloody stool due to ulcerative colitis during low-carbohydrate weight-loss diet

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.

Why seeds produced by a plant are not the same?

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

Chemical priming: a way to increase plant protection against stress conditions in the field?

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

Assessing plant responses to gravity may be the key to unlocking Martian agriculture

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
