A multidisciplinary, international team, has uncovered a new biochemical mechanism fundamental to plant life. Their research details the discovery of the enzymatic reaction involving carbohydrates present in plant cell walls, which are essential for their structure.
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.
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 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.
In recent years, the number of people affected by coeliac disease, wheat allergy or gluten or wheat sensitivity has risen sharply. But why is this the case? Could it be that modern wheat varieties contain more immunoreactive protein than in the past? Results from a new study are helping to answer this question.
An international team has decoded the full genome for the black mustard plant—research that will advance breeding of oilseed mustard crops and provide a foundation for improved breeding of wheat, canola and lentils.
Researchers use a new method of in vivo biosensor technology. Almost all life on Earth, in particular our food and our health, depend on metabolism in plants. In order to understand how these metabolic processes function, researchers are studying key mechanisms in the regulation of energy metabolism.
Bacterial road map offers new targets for Huanglongbing disease treatments. Scientists are closer to gaining the upper hand on a disease that has wiped out citrus orchards across the globe. New models of the bacterium linked to the disease reveal control methods that were previously unavailable.
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.
Asterids comprise around 100,000 flowering plants, from heather to tomatoes. Up to now, their family relationships had not yet been fully clarified. A new study by the has now somewhat closed this knowledge gap. It is the world’s most detailed phylogenetic analysis ever conducted for asterids.
