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

Invertase effect localized on the cell wall on resistance of potato plants to low temperatures

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,

Contamination of newly built thermal plants – does water hold the answer?

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

Advantageous adventitious roots – ecology, economy, and our existence

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

Do plants have brains?

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,

How plant virus hides from the host cellular degradation machinery

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

Harmful algal blooms in the Mar Piccolo: what effect may they have on local mariculture?

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

The fate and influence of engineered nanoparticles in wastewater treatment plants

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

Fungal burden in waste industry: an occupational risk to be solved

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

Development of cheap, eco-friendly and sustainable amendments to improve plant growth

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.

Silencing suppressor proteins shape virus-host co-evolution

Plant viruses are amongst the most important pathogens causing huge economic losses worldwide by reducing crop quality and quantity. A better understanding of the viral infection processes and plant defense strategies is important for crop improvement. During

Advancing medicine and agriculture using proteins that control energy and sugar production

Except for bacteria , most living organisms contain specialized cellular compartments termed mitochondria , that are responsible for breaking down sugars to produce energy for the cell. Plant cells possess a second compartment called chloroplasts , which

Do you know that some legume species have great isoflavone contents?

Different plant species are often indicated as natural sources of healthy components, such as the well-known phenolic compounds. However, considering the great variety of plant species, as also the diversity of their compounds, the true potential of

Plant flavonoids prevent cancer progression through suppression of new blood vessel formation

Flavonoids are a sub-family of polyphenolic compounds. They are abundantly found in plants and known to have inhibitory properties in the initiation, promotion and progression of invasive cancers. Cancer progression is a complex process. It is mainly

Virus containing mealybug DNA kills mealybug

One way of self-regulating protein synthesis by animals is suppression of the relevant messenger RNA (mRNA); molecules that translate into amino acids and act as building blocks for protein. The mechanism, called RNA interference (RNAi), works by

GM herbicide-tolerant crops, weedkillers, and resistant weeds: overview and interplay

Since their beginnings, GM crops have been a subject of debate in spite of their quick adoption by farmers in several countries. In the last 20 years GM herbicide-tolerant (HT) crops, generally glyphosate-tolerant crops, have been the

How does phytohormone abscisic acid regulates plant flowering time?

Optimum of flowering time is most important for modern agricultural production system, especially for crops yield and seeds quality. Furthermore, during the lifecycle of a plant, one of the most attractive biological processes in plant research field

Rust proofing the humble oat: wild cousins to the rescue

Crown rust is a disease caused by the fungus Puccinia coronata (Pc) that leads to a reduction in grain-yield of the oat crop and other cereals. Rust diseases of oat and cereals like wheat and barley result

Conserved nitrogen-regulated network modules in rice

The goal of this research work is to transfer “network knowledge” from a data-rich model plant, Arabidopsis, to rice, to enhance the identification of nitrogen gene networks in a data-poor crop. Our working example for this study

The genesis of plant languages: How plants evolve new metabolic pathways from existing ones

There are an estimated 100 million species on this planet, with a stunning array of shapes, sizes, physiologies and behavior. One question that has excited evolutionary biologists since Darwin is – how does all of this biological
