Xylella, Trnscriptome, OQDS
<p>A strain of Xylella fastidiosa is ravaging the olive trees of Southern Apulia, Italy (Saponari et<br>
al., 2013). The bacterium causes the Olive Quick Decline Syndrome (OQDS), a disease<br>
showing symptoms of apical and marginal leaf scorching, extensive branch and twig dieback<br>
and death of the trees (Martelli et al., 2016). Transmission tests demonstrated that the<br>
Xylella fastidiosa-olive infecting strain is transmitted by the xylem-feeding meadow<br>
froghopper Philaenus spumarius (Saponari et al., 2014) whereas genome studies proved that<br>
it belongs to the subspecies pauca, sequence type 53 (Giampetruzzi et al., 2015). Field<br>
observations allowed to identify a possible source of resistance in the olive cv Leccino, which<br>
reacts with milder symptoms, and hosts a much lower bacterial concentration of bacterial<br>
cells than the locally grown cv Ogliarola salentina. A global transcriptome profiling revealed<br>
that a higher number of genes is altered upon Xylella fastidiosa infection in the susceptible<br>
cv Ogliarola salentina compared to the resistant cv Leccino, with respect to the healthy<br>
plants of the same cultivars (Giampetruzzi et al., 2016). Gene expression analysis showed<br>
that both cultivars perceive the presence of the bacterium with the involvement of<br>
membrane signaling receptors, whose characterization is ongoing. Analysis of altered genes<br>
of the susceptible cv Ogliarola salentina (expansin, early-late inducible proteins, late<br>
embryogenesis abundant proteins and involvement of the abscissic acid pathway) indicated<br>
that plants are subjected to a intense water stress. A further transcriptome analysis of the<br>
recently discovered Xylella-resistant olive cv FS17® is in process. Results of these studies will<br>
be presented.</p>
