Overspending on defense arsenal bankrupts a plant's economy

Can plants defend and grow simultaneously? The Howe lab is inching closer to answering this question, which could help us understand natural ecosystems or help farmers increase yields without increasing dependence on pesticides.

Plants, put in the dark, reveal over 100 active peroxisome proteins

A new study identifies 111 peroxisomal proteins, including six newly identified ones, in dark-treated plants. It is part of an effort to fully map the functions of plant peroxisomes.

Stressed plant roots warn the rest of the plant of looming dangers

When facing drought or heat stress, roots are advance scouts that warn the rest of the plant to prepare for the big 'hit.'

Blazes of light reveal how plants signal danger over long distances

A multi-university study reveals how plant communication systems respond to threats from herbivores. Once wounded, plants use calcium signals to warn distant tissues of future attacks.

As climate changes, plants might not suck carbon from the air fast enough

Atmospheric scientists factor lesser known photosynthesis research into their models. The result: carbon levels in the air could be much higher by 2100 than previously predicted.

Keeping up with lipids on the move: a new molecular tracking method

Scientists have created a new tracking method for plant lipids. The approach could fill our knowledge gaps of lipid movement and help us improve yields in crops targeted for biofuels.

Microbiologists and plant scientists find secret to tackling cholera [LINK]

While cholera rages across many regions of the world, a team of microbiologists and plant scientists from the Benning lab has pinpointed a genetic weakness in the pandemic’s armor, which could lead to future treatments.

Two plant cell 'hotspots' tell the cell where to import its resources

The two proteins, called VAP, indicate where endocytosis, a form of transport in which a living cell imports molecules, should occur.

Study shows how a gene helps plants manage their protein production in stressful times

The NPR1 gene keeps the unfolded protein response, a plant fail-safe for stressful times, in check.

SPL1 protein plays a positive role in building plant cell peroxisomes

Understanding how the plant cell's food processors are built might help us breed better plants and even benefit human medicine.

When lipids meet hormones: plants' answer to complex stresses

How plants harvest their own chloroplasts - photosynthesis machines that make their food - to help defend against outside threats.

Stress tested: how algae change their internal solar panels to stay alive

The natural solar panels constantly grow and shrink in size to adjust to changes in their hosts' environments. Scientists want to tap into this energy source for biofuels and food purposes.

How detecting light in the water affects how much food cyanobacteria get

Scientists have linked how water-dwelling bacteria monitor light wavelengths in their surroundings with their capacity to do photosynthesis. The research has medical/biofuels implications.

SP1 protein interacts with three energy-related cellular organelles

The protein, which helps to construct peroxisomes, also interacts with chloroplasts and mitochondria. The organelles are important for generating and managing plant energy supplies.

Reviewing photosynthesis in dynamic conditions: Photosystem I as a guard

The fundamental protein complex potentially guards plants from high light and ageing effects. This new observation could change how we view photosynthesis.

Growing a garden in space

Scientists are studying how plants adapt to space environments. The NASA funded research aims to help us grow fresh produce beyond the planet Earth.

How plants 'muscle up' as they prep for the cold

A protein that helps plants prepare for the cold also helps them beef up for bacterial attacks, as a precautionary measure.

Fighting plant disease at warm temperatures keeps food on the table [VIDEO]

The Nature Communications study shows how high temperature weakens plant defenses while, separately, strengthening bacterial attacks.

How to build artificial nanofactories to power our futures: Logistics

A peek into the logistics of how bacterial nanofactories move electrons, towards creating chemical products. Future apps include renewable energy and medical tools.

Taking the brakes off plant production: not so good after all

When engineers want to speed up a system, they look for the slowest steps and make them faster. In plants, this approach potentially does more harm than good, says the Kramer lab.
