Genetic engineers create smarter toxins to help crops fight resistant pests
One of the most successful strategies in pest control is to endow crop plants with genes from the bacterium Bacillus thuringiensis, or Bt for short, which code for proteins that kill pests attempting to eat ...
With secondhand gene, 'freaky mouse' defeats common poison
Over millennia, mice have thrived despite humanity's efforts to keep them at bay. A Rice University scientist argues some mice have found two ways to achieve a single goal -- resistance to common poison.
Researchers unravel role of priming in plant immunity
Scientists have discovered a naturally occurring compound that triggers a plant's immune system, thereby protecting the plant from a secondary bacterial infection.
Scientists publish complete genetic blueprint of key biofuels crop
Scientists at the U.S. Department of Energy (DOE) Joint Genome Institute (JGI) and several partner institutions have published the sequence and analysis of the complete genome of sorghum, a major food and ...
Thames study: Rivers can be a source antibiotic resistance
Rivers and streams could be a major source of antibiotic resistance in the environment.
Habitat fragmentation increases vulnerability to disease in wild plants
Proximity to other meadows increases disease resistance in wild meadow plants, according to a study led by Anna-Liisa Laine at the University of Helsinki. The results of the study, analyzing the epidemiological ...
Biologists develop nanosensors to visualize movements and distribution of plant hormone
Biologists at UC San Diego have succeeded in visualizing the movement within plants of a key hormone responsible for growth and resistance to drought. The achievement will allow researchers to conduct further ...
'Master regulator' protein controls flowering, disease resistance in plants
(Phys.org) —The next time you stop and smell the roses, thank MED18. The protein MED18 controls many important plant processes, including when a plant blossoms, how it resists key fungal diseases, and how it responds to ...
'Superbugs' found breeding in sewage plants
(Phys.org) —Tests at two wastewater treatment plants in northern China revealed antibiotic-resistant bacteria were not only escaping purification but also breeding and spreading their dangerous cargo.
Scientists uncover mechanism for natural plant immunity
Scientists in Norwich and China have, for the first time, uncovered exactly how an immune receptor mediating plants' natural immunity to bacteria works.
Australian tarantula venom contains novel insecticide against agricultural pests
Spider venoms are usually toxic when injected into prey, but a new protein discovered in the venom of Australian tarantulas can also kill prey insects that consume the venom orally. The protein is strongly ...
Scientists help deliver genetic one-two blow to deadly wheat disease
(Phys.org) —A new gene that will equip wheat plants to resist the deadly stem rust disease has been discovered by an international team that includes plant scientists at the University of California, Davis.
Geneticists show COPIA-R7 transposon enhances immunity of its host against pathogenic microorganism
(Phys.org) —Transposons are DNA elements that can multiply and change their location within an organism's genome. Discovered in the 1940s, for years they were thought to be unimportant and were called "junk ...
Resistance gene found against Ug99 wheat stem rust pathogen
The world's food supply got a little more plentiful thanks to a scientific breakthrough. Eduard Akhunov, associate professor of plant pathology at Kansas State University, and his colleague, Jorge Dubcovsky from the University ...
