Researchers Discover Novel Molecular Mechanism That Enables Conifers to Adapt to Winter

By | Forestry, News, Scandinavian Plant Physiology Society

Photosynthesis in conifer forests is one of the most important carbon sinks on a global scale. Unlike broadleaf trees, conifers are evergreen and retain their photosynthesis structure throughout the year. Especially in late winter, the combination of freezing temperatures and high light intensity exposes the needles to oxidative damage that could lead to the destruction of molecules and cell structures that contribute to photosynthesis. Researchers have discovered a previously unknown mechanism that enables spruce trees to adapt to winter.

Discovered a new method of biofortification that transforms leaves into nutrient stores

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

A new collaborative study describes a promising strategy to improve the nutritional benefits of crops. The work proposes the controlled transformation of chloroplasts (organelles that conduct the photosynthesis in leaves) into chromoplasts (organelles specialized in producing and storing large amounts of carotenoids). Free of substances harmful to the environment, this technology has been patented and opens new perspectives for the nutritional improvement (biofortification) of crops and for the sustainable production of carotenoids of interest to the cosmetic, pharmaceutical and food industries.

Researchers Discover a New Role for a Well-Known Molecule as a Plant Hormone, with Implications for Seed Production and Crop Yield

By | Agriculture, News, Plant Health, Plant Science

Researchers have discovered a new role for a well-known plant molecule, providing the first clear example of ACC acting as a likely plant hormone. Researchers show that ACC has a critical role in pollination and seed production by activating proteins similar to those in human and animal nervous systems. Findings could change textbooks and open the door for research to improve plant health and crop yield.

How Plants Shut the Door on Infection

By | Agriculture, News, Plant Health

Plants have a unique ability to safeguard themselves against pathogens by closing their pores—but until now, no one knew quite how they did it. Scientists have known that a flood of calcium into the cells surrounding the pores triggers them to close, but how the calcium entered the cells was unclear.

A new study by an international team reveals that a protein called OSCA1.3 forms a channel that leaks calcium into the cells surrounding a plant’s pores, and they determined that a known immune system protein triggers the process.
