How a Molecular “Alarm” System in Plants Protects Them from Predators

By | Agriculture, News, Plant Health, Plant Science

Some plants, like soybean, are known to possess an innate defense machinery that helps them develop resistance against insects trying to feed on them. However, exactly how these plants recognize signals from insects has been unknown until now. In a new study, scientists have uncovered the cellular pathway that helps these plants to sense danger signals and elicit a response, opening doors to a myriad of agricultural applications.

Researchers develop biotechnological process for jasmonic acid production

By | News, Plant Health, Plant Science, Research

Plants produce the hormone jasmonic acid as a defence response when challenged. This is how they ensure that their predators no longer like the taste of their leaves. Biologists want to find out whether biological precursors and other variants of jasmonic acid lead to similar or different effects. But such derivatives of the hormone have so far been too expensive for experiments and difficult to come by. Researchers have now found a method that might make the production of a biologically significant precursor of jasmonic acid more efficient and cheaper.

​​Sweet potato microbiome research important first step towards improving yield

By | Agriculture, Fruits and Vegetables, News, Plant Health, Plant Science

Grown around the world, sweet potatoes are an important source of nutrition particularly in sub-Saharan African and Asian diets. Sweet potatoes are especially significant to sub-Saharan Africa as a source of Vitamin A, a nutrient commonly deficient in the region. While China currently produces the most sweet potatoes by country, sub-Saharan Africa has more land devoted to sweetpotatoes and continues to expand production. Farmers elsewhere are also increasingly growing sweetpotatoes.

The harmful effect of ozone on plants

By | News, Plant Health, Plant Science

A research team has successfully quantified and visualised the impact of Hong Kong air pollution especially ozone pollutant on plants and the environment. Although the experiment took place in a rural area and in Spring, which would usually have a lower average ozone concentration, the pollutant level still reached high enough to do significant damage.

Scientists are working to protect invaluable living collections during coronavirus lockdowns

By | Agriculture, News, Plant Health, Plant Science, Research

Staying on top of these collections is time-consuming during the best of times, and this task becomes even more complex in the age of social distancing. Yet thousands of scientists across the globe are doing just that, maintaining everything from crickets, to tissue cultures, mice, powdery mildews, nematodes, psyllids, zebrafish and even rust fungi.
