Discovery may help alleviate the increasing global problem of high soil salinity on farmland

To avoid salt in soil, plants can change their root direction and grow away from saline areas. University of Copenhagen researchers helped find out what makes this possible.

UJ scientists find a faster way to screen soil bacteria as potential biologicals

Researchers found a much faster way to screen soil bacteria as potential biostimulants and bio-pesticides.

Conserved vacuolar sorting hub regulates autophagic flux in plants

A “hub and spoke” system allows plant cells to effectively coordinate cellular trafficking, especially for cellular recycling, also known as autophagy. Autophagosomes are specialized vesicles that capture hazardous molecules and transport them to the vacuole, where they are destroyed.

Discovering H2O2 sensing capacity in plants that control immunity

All aerobic organisms produce the molecule hydrogen peroxide (H2O2). When present in low concentrations, it acts as a crucial secondary signal to control a variety of biological processes, including but not limited to plant-microbe interactions, abiotic stress tolerance, pollen tube growth, root hair formation, leaf cell expansion, and Casparian strip formation.

Harsh parenting leads to depression later in life

Strict parenting can influence how the body reads the children’s DNA. These modifications can become “hard-wired” into the DNA of kids who consider their parents to be harsh, enhancing their biological risk for depression in adolescence and later life.

Role of hormones and their receptors in the plant stress response

Crops are frequently subjected to unfavorable growing conditions. Disease, severe temperatures, and saline soils, for example, cause plants to utilize energy to adapt to stress rather than for development.

The influence of fatty acid metabolism on plant immunity

Most people do not realize that fatty acids can be found in a nutritious salad. Although fatty acids, lipids, and fats may seem unappealing, they are essential to human life and to the plants that are consumed.

Spores integrate environmental signals over time

When exposed to starvation and stress, certain bacteria enter a dormant state in which life functions cease. These cells, known as spores, can resist punishing extremes of heat, pressure, and even the extreme conditions of outer space by entering a profound hibernation.

Interactional closeness with a dog can increase prefrontal brain activity

Researchers led by Rahel Marti at the University of Basel in Switzerland report that viewing, feeling, and touching real dogs leads to increasingly higher levels of activity in the prefrontal cortex of the brain.

Multi-institutional project aims to deepen the understanding of a versatile bioenergy crop

Principal Investigator, Andrea Eveland, Ph.D., associate member at the Donald Danforth Plant Science Center, will lead a multi-institutional project to deepen the understanding of sorghum, a versatile bioenergy crop, and its response to drought.

“Junk” DNA could provide access to innovative treatments for neurological conditions

The breakthrough study from the University of Sheffield’s Neuroscience Institute and Healthy Lifespan Institute offers critical new insights into the so-called junk DNA, or DNA that was previously believed to be unimportant to the coding of the genome, and how it affects neurological disorders like Motor Neuron Disease (MND) and Alzheimer’s.

Dogs can discriminate between baseline and stress odors

The physiological processes associated with an acute psychological stress response produce changes in human breath and sweat that dogs can detect with an accuracy of 93.75%, according to a new study published this week in the open-access journal PLOS ONE by Clara Wilson of Queen's University Belfast, UK, and colleagues.

Discovery of genes lending tolerance to sugarcane from pests, cold, and drought

Saccharum spontaneum, a species of wild sugarcane with exceptional resistance to biotic stresses like nematodes, fungi, bacteria, and other pests and diseases, as well as abiotic stresses like cold, drought, salinity, and nutritionally deficient soil, was the subject of a study at the State University of Campinas (UNICAMP) in Brazil.

Chemical compounds play a pivotal role in host selection behaviors

A team of researchers headed by UC Riverside found that the combination of carbon dioxide and two chemicals—2-ketoglutaric and lactic acids—evokes a scent that kindles the mosquito to trace and land on its victim.

Rumen-protected lysine improves uterine health

Boosting milk yield when included in the diet at sufficient levels, lysine is an important amino acid for dairy cows. But how could lysine be advantageous for cows in other means? A new study by the University of Illinois reveals that rumen-protected lysine can enhance uterine health if given in the transition period.
