New-and-improved protein-rich rice has higher yields

Ben Coxworth January 23, 2019

According to the ASA, it's an unfortunate fact that many people in developing nations don't get enough protein in their diets. What they often do get a lot of, however, is rice. So, scientists have improved upon a type of rice that has over 50 percent more protein than regular varieties.

Bioengineered rice delivers significant increases in grain yields

Rich Haridy January 13, 2019

Research has demonstrated a novel technique to enhance photosynthetic efficiency in rice crops can increase grain yields by up to 27 percent. The study follows other recent demonstrations of food bioengineering designed to enhance worldwide food productivity by improving the photosynthesis process.

On the far left is a wild, unenhanced rice plant, and the other three display improved ...

Scientists hack plant photosynthesis to boost crop yields by 40%

Rich Haridy January 3, 2019

A team of researchers has, for the first time, demonstrated that by fixing a common glitch in photosynthesis, a crop’s yield could be improved by around 40 percent. The landmark study suggests optimizing a plant’s photosynthetic efficiency could significantly increase worldwide food productivity.

The genetically modified crops grow faster and taller than their conventional counterparts

New-and-improved agri-robot hits the vineyards

Ben Coxworth September 21, 2018

Back in 2015, we heard about a prototype vineyard-monitoring robot known appropriately enough as VineRobot. Now, its successor has been unveiled in Portugal. Developed via a European Union research consortium, it's called VineScout.

VineScout is capable of checking crops both day and night

"Herculean" research finally sequences wheat genome after 13 years of work

Rich Haridy August 16, 2018

After a massive international effort involving over 200 scientists across 20 countries, the entire wheat genome has been finally sequenced. The landmark human achievement is hoped to lead to more efficient wheat breeding and production of crops.

The massive achievement should accelerate research into the breeding of more resilient and higher yielding wheat ...

Plasticine caterpillars show how birds could protect crops

Ben Coxworth August 15, 2018

Although the scent of freshly-cut grass may SEEM nice, what you're actually smelling is a distress signal. Thanks to a recent-conducted study, scientists from the University of Delaware now believe that such signals could be used to summon insect-eating birds to valuable crops.

Hungry plants could learn a thing or two from nitrogen-fixing bacteria

Michael Irving July 17, 2018

Nitrogen is a vital nutrient for plants, but they can't pull it out of the air, hence the need for artificial fertilizer. But now, researchers have engineered bacteria that can efficiently suck nitrogen out of the air, and the long-term goal is to develop crops that can do the same.

Researchers have engineered bacteria to absorb nitrogen from the air, with the eventual goal of developing ...

A tobacco-derived insect repellent – for crops

Ben Coxworth June 7, 2018

Although it's associated with nasty cigarettes, the tobacco plant is also a potential source of vaccines, biofuel and antibiotics. Now, a chemical from the plant is also being used as a bug repellent for crops, which could replace eco-unfriendly insecticides.

If aphids have the choice between wheat seedlings with (right) and without CBT-ol treatment (left), they ...

Crops successfully engineered to need 25 percent less water

Rich Haridy March 7, 2018

Scientists have revealed that a genetic tweak to a single protein could result in crops needing up to 25 percent less water to produce a regular yield. It's hoped the breakthrough will lead to a new generation of water-efficient agriculture.

Successfully trialled in a crop of tobacco, the genetically engineered plants require 25 percent less water ...

NASA-inspired "speed breeding" boosts wheat production threefold

Nick Lavars January 1, 2018

Our planet is expected to host an extra two billion people by 2050, making food security a real issue. Researchers are now reporting an advance in a field known as speed breeding, which relies on intense lighting regimes to raise crops several times faster.

The speed breeding technique was developed by scientists at the University of Sydney, the University of ...
