Experimental basis for the control of plant diseases caused by Xylella fastidiosa using synthetic antimicrobial peptides
Xylella fastidiosa is one of the most damaging phytopathogenic bacteria in the world, causing a variety of diseases with a major economic impact on agriculture and the environment. Until now, no therapeutic solution has been found for its control in affected plants and trees. Antimicrobial peptides...

| Resumo: | Xylella fastidiosa is one of the most damaging phytopathogenic bacteria in the world, causing a variety of diseases with a major economic impact on agriculture and the environment. Until now, no therapeutic solution has been found for its control in affected plants and trees. Antimicrobial peptides (AMPs) represent a promising alternative to traditional compounds due to their activity against a wide range of plant pathogens, low toxicity, mode of action, and availability to create sustainable pesticides as well as disease-resistant crops. Thus, the aim of the present Ph.D. thesis was focused on the study of AMPs as a sustainable alternative for the control of diseases caused by X. fastidiosa. In addition to identifying highly bactericidal AMPs, highlighting important parameters of their activity, the aggressiveness of Spanish isolates of X. fastidiosa was studied in order to design efficient treatment guidelines for its control |
