Spain: They propose the genetic analysis of a pathogenic bacterium of the olive grove to combat its effects

Tridge summary

A research team from the Institute for Sustainable Agriculture, the Institute for Sustainable Plant Protection, and the LMU Biocenter is conducting a genetic analysis of Xylella fastidiosa, a bacterium that causes the die-off of olive, almond, and other trees. The study aims to predict which crops will be affected and understand the bacterium's interaction with the host plant and microbiome. So far, research has focused on strains that cause visible symptoms, neglecting those that coexist with the plant's microbiome without causing disease. The team is also developing strategies to prevent and mitigate crop diseases, including rapid and sensitive diagnostic techniques.

An international and multidisciplinary research team from the Institute for Sustainable Agriculture (IAS-CSIC), the Institute for Sustainable Plant Protection (IPSP, Italy) and the LMU Biocenter in Munich (Germany) propose the genetic analysis of a pathogenic bacterium of the olive grove to combat its effects. This microorganism, Xylella fastidiosa, also affects other species of agricultural interest in Europe such as almond trees and vines, causing them to dry up and die. The researchers point out that analyzing the genome of this bacterium could help predict which crops will be susceptible to its adverse effects. Xylella fastidiosa is a pathogenic bacterium considered a priority pest in Europe, since there is no effective control method to eradicate it. In Spain, it has been detected in wild species and crops in Alicante and the Balearic Islands. Although it is estimated that it resides in more than 500 species, it only shows adverse effects in certain plants, such as olive or ...
