Integrated crop-livestock system brings more sustainability to flooded rice.
Plant-derived chemicals called cardenolides - like digitoxin - have long been used to treat heart disease, and have shown potential as cancer therapies. But the compounds are very toxic, making it difficult for doctors to prescribe a dose that works without harming the patient. Researchers now show that the wormseed wallflower could be used as a model species to elucidate how plants biosynthesize cardenolides, knowledge that could aid the discovery and development of safer drugs.
In a way, plants are energy wasters: in order to protect themselves from excessive electron transport, they continuously quench light energy and don't use it for photosynthesis and biomass production. A mutation can make them work more efficiently, as was discovered by a team from Ruhr-Universität Bochum (RUB) and Martin Luther University Halle-Wittenberg (MLU).
A warming global climate could cause sudden, potentially catastrophic losses of biodiversity in regions across the globe throughout the 21st century, finds a new UCL-led study published in Nature.
Promising new pinto bean released with increased leafhopper resistance.
As agriculture emerged in early civilizations, crops were domesticated in four locations around the world -- rice in China; grains and pulses in the Middle East; maize, beans and squash in Mesoamerica; and potatoes and quinoa in the Andes. Now, an international team of researchers have confirmed a fifth domestication area in southwestern Amazonia where manioc, squash and other edibles became garden plants during the early Holocene, starting over 10,000 years ago.
Bacterial canker is caused by the pathogen Clavibacter michiganensis, which infects commercially bred tomatoes by colonizing the xylem, a series of tubes that transports water and minerals throughout the plant. There are no commercially available tomatoes resistant to bacterial canker and management options are limited. However, breeders have known that wild tomato species are less susceptible to bacterial canker, but this knowledge is limited.
A pair of chemicals used by wallflowers and their kin to ward off predators have evolved to complement each other, with one targeting generalist herbivores and the other targeting specialized herbivores that have become resistant to the generalist defense.
A protein hijacked from a bacterial pathogen helps to facilitate more precise genome editing in plants.
Some flowers have a remarkable and previously unknown ability to bounce back after injury, according to a new study.
