Fungal and bacterial oxylipins are signals for intra- and inter-cellular communication within plant disease.

Lipids are central at various stages of host-pathogen interactions in determining virulence and modulating plant defense. Free fatty acids may act as substrates for oxidizing enzymes [e.g.

Intra-Laboratory Evaluation of DNA Extraction Methods and Assessment of a Droplet Digital PCR for the Detection of Xanthomonas citri pv. citri on Different Citrus Species.

pv. (Xcc) and pv. (Xca), causal agents of citrus bacterial canker, are both regulated by the European Union to prevent their introduction.

Mass Spectrometry-Based Targeted Lipidomics and Supervised Machine Learning Algorithms in Detecting Disease, Cultivar, and Treatment Biomarkers in subsp. -Infected Olive Trees.

In 2013, was detected for the first time in Apulia and, subsequently, recognized as the causal agent of the olive quick decline syndrome (OQDS). To contain the disease, the olive germplasm was evaluated for resistance to , identifying cultivars with different susceptibility to the pathogen. Regarding this, the resistant cultivar Leccino has generally a lower bacterial titer compared with the susceptible cultivar Ogliarola salentina.

The Effect of Fumonisins on Fatty Acids, Sphingolipids, and Oxylipins in Maize Germlings.

causes multiple diseases of (maize) including ear and seedling rots, contaminates seeds and seed products worldwide with toxic chemicals called fumonisins. The role of fumonisins in disease is unclear because, although they are not required for ear rot, they are required for seedling diseases. Disease symptoms may be due to the ability of fumonisins to inhibit ceramide synthase activity, the expected cause of lipids (fatty acids, oxylipins, and sphingolipids) alteration in infected plants.

Further In Vitro Assessment and Mid-Term Evaluation of Control Strategy of subsp. in Olive Groves of Salento (Apulia, Italy).

During recent years; subsp. (Xfp) has spread in Salento causing relevant damage to the olive groves. Measures to contain the spreading of the pathogen include the monitoring of the areas bordering the so-called "infected" zone and the tree eradication in case of positive detection.

Xylella fastidiosa subsp. pauca and olive produced lipids moderate the switch adhesive versus non-adhesive state and viceversa.

Global trade and climate change are re-shaping the distribution map of pandemic pathogens. One major emerging concern is Xylella fastidiosa, a tropical bacterium recently introduced into Europe from America. In last decades, X.

Lipid Profile of Subsp. Associated With the Olive Quick Decline Syndrome.

Lipids, components of the plasma and intracellular membranes as well as of droplets, provide different biological functions related to energy, carbon storage, and stress responses. Bacterial species display diverse membrane composition that changes in response to the different environmental conditions. During plant-pathogen interactions, lipids might have roles in several aspects such as recognition, signal transduction, and downstream responses.

HPLC and NMR analysis of the phenyl-ethanoid glycosides pattern of Verbascum thapsus L. cultivated in the Etnean area.

In this work the HPLC and NMR analysis of the phenyl-ethanoid glycosides (PhGs) pattern of a cultivated exemplar of Verbascum thapsus L. (Scrophulariaceae) from the Etnean area (Sicily, Italy) was performed in order to verify their possible presence. Wild V.
