Cereals use chemical defenses in a multifunctional manner against different herbivores

Scientists have characterized multiple functions of benzoxazinoids in wheat: The toxic form of the substances makes the plant directly resistant to lepidopteran larvae, whereas a less toxic form regulates indirect defense mechanisms against aphids. The researchers identified the 'switch' between these different functions as a methyltransferase enzyme, which is activated by caterpillar feeding. This switch enables wheat plants to adapt their defense response to different herbivores. from Latest Science News -- ScienceDaily https://ift.tt/2zHdNEb

A detailed look at the microorganisms that colonize, and degrade, a 400-year-old painting

What's a feast for the human eye may be a literal feast for microorganisms that colonize works of art, according to a new study. The researchers characterized the microbial community on a 17th century painting and showed that while some microbes destroy such works of art, others might be employed to protect them. from Latest Science News -- ScienceDaily https://ift.tt/2AUfmyu
