Nanotechnology, is it something useful for future agriculture?

Nanotechnology has been applied in various fields – biomedicine, electronic devices, renewable energy   optical electronic medicine, physics, pharmaceutics. Does it have a place in agriculture? It is generally accepted that manipulation of a crop’s native microbiome represents

Signaling crosstalk in the Ve-resistance locus of tomato

Influence of Ve1 gene on tomato root size

Verticillium is a fungal pathogen that causes vascular wilt disease in over 200 species of plants, including many crops. The fungus invades through the root and enters the water conducting xylem where it proliferates and rapidly becomes

Use of plant growth–promoting rhizobacteria (PGPR) in stressed agriculture management

Some of action mechanisms of PGPR in alleviating abiotic stresses in plants

Enhanced incidence of abiotic stresses influencing adversely plant growth and productivity in major crops, and thus global food security, is being witnessed all over the world. These abiotic stress factors include drought (water deficit) and flooding, salinity,

Fruit of the heirloom: ancient non-commercial plant varieties as superior sources of health-beneficial compounds

Lands subtracted to intense urbanization are home of a rich biodiversity, which is well exemplified by the occurrence of many different plant species. Plants thriving in such areas have established a perfect synergy with the local environment,

Aggregation properties as potential markers for classifying rubber particle proteins

Natural rubber is an important biopolymer that mainly consists of cis-1,4-polyisoprene. The rubber tree Hevea brasiliensis is the only commercially viable source of natural rubber because of its good yield and the product’s high quality. Rubber elongation

Back to the future: Italian folk remedies to heal headache (XIX-XX century)

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

mRNA Interactome Capture: a frontier method to discover mRNA-bound proteomes in plants

Cells are the structural and functional basic units of a given organism to support its life. The phenotype of an organism is highly determined by proteins at the molecular level in each cell. Imbalance of gene expression

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

Live-cell imaging revealed the dynamics and the roles of cytoskeleton in polarizing plant zygote

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,

Emerging roles of cyclic nucleotide gated channels in plants

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 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
