Mutant corn gene found to increase the amount of sugars in the seeds and leaves

An abnormal accumulation of carbohydrates—starches and sugars—in the kernels and leaves of a mutant line of corn can be traced back to a single misregulated gene, and this finding provides insights into how the plant responds to stress.

Researchers devise a small-molecule cocktail to protect stem cells from stress

Researchers at the National Institutes of Health (NIH) have devised a four-part small-molecule cocktail that can protect stem cells called induced pluripotent stem cells (iPSCs) from stress and maintain normal stem cell structure and function.

Plant biodiversity is sensitive to precipitation changes, shows study

Water is a scarce resource in many of the Earth's ecosystems. This scarcity is likely to increase in the course of climate change.

Researchers offer perspective on how to achieve field-scale precision irrigation

With threats of water scarcity complicating the need to feed a growing global population, it is more important than ever to get crop irrigation right.

Genetically encoded sensor helps detect hallucinogenic substances

Researchers at the University of California, Davis, have created a genetically encoded sensor for detecting hallucinogenic substances.

Increased expression of DUSP16 molecule leads to cancer chemoresistance

Chemotherapy is a drug treatment that uses powerful chemicals to kill fast-growing cancer cells in the body. It is a systemic treatment where drugs travel throughout the body and destroy cancer cells that have spread (metastasized) to parts of the body far away from the original (primary) tumour.

Study shows that autophagy plays a key role in messenger RNA degradation

Autophagy is essential in messenger RNA (mRNA) degradation, according to researchers from the Tokyo Institute of Technology (Tokyo Tech).

Critical intermediate in normal cellular metabolism may lead to cell death

A recent study shows that a critical intermediate in normal cellular metabolism is also a cause for cell death in the right sense.

SDIR1 enzyme plays a major role in the expression of defense gene in plants

A new study offers evidence that microbes are trying to hijack the plant immune system to induce disease while also offering insights into a new mechanism.

Chaperone protein imbalance initiates toxic accumulation of tau in the aging brain

Chaperone protein imbalance can play a significant role in initiating toxic accumulation of tau in the aging brain - an early step in the development of Alzheimer's disease and related neurodegenerative disorders known as tauopathies, a new preclinical study by University of South Florida Health (USF Health) neuroscientists suggests.

Study highlights the importance of autophagy in gene regulation

A fine balance between the production and degradation of biomolecules is required for optimal cell function. Autophagy is a mechanism through which cells break down and recycle their own components.

Researchers use information embedded in microbial genes as a biosensor of ocean health, productivity

Scientists from the University of California, Irvine, analyzed gains and losses in the genes of phytoplankton samples gathered from all major ocean regions to develop the most refined and highest-resolution map that shows where these photosynthetic organisms either survive or are forced to adapt to restricted amounts of main nutrients, nitrogen, iron, and phosphorus.

Gene therapy protects eye cells in mice with retinitis pigmentosa

A gene therapy protects eye cells in mice with a rare disorder that causes vision loss, especially when used in combination with other gene therapies, shows a study published today in eLife.

Study reveals DNA supercoiling is involved in regulating gene expression

The (when stretched) two-meter-long DNA molecule in each human cell is continuously being unpacked and packed again to enable the expression of genetic information.

Researchers identify and test drug combination that exploits a weakness in small cell lung cancer

Researchers from the National Institutes of Health have identified and tested a drug combination that exploits a weakness in small cell lung cancer (SCLC), an aggressive, dangerous cancer.

Warped immune cell signaling during bile acid exposure may lead to Crohn’s disease

People with Crohn's disease are typically treated with powerful anti-inflammatory medications that act throughout their body, not just in their digestive tract, creating the potential for unintended, and often serious, side effects.

High ozone concentrations decrease crop yield in maize

Although stratospheric ozone protects us by filtering out the sun's ultraviolet radiation, tropospheric ozone is a harmful pollutant. A new study has shown that ozone in the lower layers of the atmosphere decreases crop yields in maize and changes the types of chemicals that are found inside the leaves.

Researchers use single-cell RNA sequencing to study the development of leaves

How do we become a complex, integrated multicellular organism from a single cell? While developmental biologists have long researched this fundamental question, Stanford University biologist and HHMI investigator Dominique Bergmann's recent work on the plant Arabidopsis thaliana has uncovered surprising answers.
