16S libraries of endophytic communities in olive trees subjected to salt stress

Paired-end sequences spanning the V3–V4 regions of the bacterial 16S rRNA. Bacterial metabarcoding of Olive tree samples subjected to salt stress. 4 cultivars (Frantoio, Leccino, Lecciana, and Oliana), three experimental conditions (Control, 100 mM and 200 mM of sodium chloride) and two-time points (T0, at the beginning of the experiment; T1, at the end of the experiment) were used. Metabarcoding data were then coupled with pigment and proline analyses to better describe the olive tree response to salinity stress. Lecciana; "Lc" Leccino; "Lcc" Oliana; "Og" Frantoio; "Fr" The library acronym includes the cultivar (e. g., Lc), the time point (e. g., t1), the treatment (e. g., 200), and the replicate (e.g., 3).
