Dear MEL Topic Readers,

Deadly olive tree disease across Europe ‘could cost billions’

Xylella fastidiosa is an aerobic, Gram-negative bacterium of the monotypic genus Xylella. It is considered to be one of the most dangerous pathogens for plants as no cure for the infection has been found yet. Xylella could infect cherry, almond, plum trees, and olives. In Europe, olive trees were the main victim of the pathogens. Once infected, the tree is limited the ability to move water and nutrients, thus it withers and dies.

For the world’s three largest olive oil producers, Spain, Greece, and Italy, this bacterium is as deadly as coronavirus to the economy. Though trees don’t move around to spread the disease like careless humans, insects do. Until researchers come up with the disease-resistant trees, the only way to cope with this disease is to remove infected trees. Now, in the midst of the COVID-19 pandemic, which has been devastating Italy, this olive killer bacterium is spreading across the country’s plantations. For those who depend on olive oil for their cooking and dining, this could have a huge impact on their diet and wallet.

Read the article and learn about an outbreak of this deadly plant pathogen.
