A red future for improving crop production?

By | Australian National University, News

Researchers have found a way to engineer more efficient versions of the plant enzyme Rubisco by using a red-algae-like Rubisco from a bacterium. For 50 years scientists have striven to boost the activity of Rubisco, a promising target to increase crop production, as it controls how much and how fast plants fix carbon dioxide from the atmosphere into sugars and energy during photosynthesis.

E. coli bacteria offer path to improving photosynthesis

By | ASPB, News, Plant Science, Research

Scientists have engineered a key plant enzyme and introduced it in Escherichia coli bacteria in order to create an optimal experimental environment for studying how to speed up photosynthesis, a holy grail for improving crop yields. Scientists have known that crop yields would increase if they could accelerate the photosynthesis process, where plants convert carbon dioxide (CO2), water and light into oxygen and eventually into sucrose, a sugar used for energy and for building new plant tissue.

Despite debate, even the world’s oldest trees are not immortal

By | News, Plant Science, Spanish Society of Plant Physiology

The oldest trees on Earth have stood for nearly five millennia, and researchers have long wondered to what extent these ancient organisms undergo senescence, physically deteriorating as they age. In a Forum recently published plant biologist argues that although signs of senescence in long-lived trees may be almost imperceptible to people, this does not mean that they’re immortal.

CRISPR enables one-step hybrid seed production in crops

By | News, Plant Science, Research

Crop hybrid technologies have contributed to the significant yield improvement worldwide in the past decades. However, designing and maintaining a hybrid production line has always been complex and laborious. Now, researchers have developed a new system combining CRISPR-mediated genome editing with other approaches that could produce better seeds compared with conventional hybrid methods and shorten the production timeline by 5 to 10 years.

Plant tissue engineering improves drought and salinity tolerance

By | Agriculture, News, Plant Science

After several years of experimentation, scientists have engineered thale cress, or Arabidopsis thaliana, to behave like a succulent, improving water-use efficiency, salinity tolerance and reducing the effects of drought. The tissue succulence engineering method devised for this small flowering plant can be used in other plants to improve drought and salinity tolerance with the goal of moving this approach into food and bioenergy crops.

How to build better highways in plants

By | ASPB, News, Plant Science

As a plant grows, it moves cellular material from its version of manufacturing sites to the cell wall construction zone. Transporter proteins, called motor proteins, are thought to move these cell wall cargo via a complex highway system made up of microtubule tracks. The position of these tracks must be stabilized so that cargo are delivered to the correct locations.
