Small RNA-seq on a time series of potato infected with Globodera pallida

We explored the sex determination of Globodera pallida. To do so, we grew cuttings of the potato cultivar Desiree on Gamborg B5 medium supplemented with either 1.5 g/L or 20 g/L sucrose. 14-day-old cuttings were inoculated with 100 G. pallida E400 Rookmaker juveniles. Infected root tissue was harvested at 1, 3, 6, and 9 dpi. Also, a subsample of the ppJ2 was kept for each batch. The experiment contains four time-separated batches. Small RNA sequencing was performed by BGI Hong Kong.
