Project description:DNA sequencing of nine Globodera pallida populations selected either for four generations on the resistant potato variety Seresta (S4), or, as a control, for one generation on the susceptible variety Desiree (D). Seresta contains GpaV from Solanum vernei as a major resistance against G. pallida. These nine populations were obtained from Dutch potato fields, where they previous to the further selection already showed some degree of virulence on resistant potato varieties. The goal of the experiment was to identify polymorphic loci in the genome associated with the selection on Seresta.

Project description:The potato cyst nematodes (PCN), Globodera pallida and Globodera rostochiensis, are important parasites of potato. PCN have complex, biotrophic interactions with their hosts that involve gene expression changes in both the nematode and the host plant. The aim of this study is to determine key genes that are differentially expressed in Globodera pallida life cycle stages and during the initiation of the feeding site in susceptible or partially resistant potato genotypes. For this purpose, two microarray experiments were designed: i) a comparison of eggs, infective second stage juveniles (J2) and sedentary parasitic stage J2s (SJ2); ii) a comparison of SJ2 at eight days after inoculation (DAI) in the susceptible cultivar (Desiree) and two partially resistant lines. The data set in this submission came from experiment (I). The results show differential expression of G. pallida genes during the stages studied, including previously characterized effectors. Also, a large number of genes changed their expression between the SJ2 in the susceptible cultivar compared to those infecting partially resistant lines; the number of genes with modified expression were smaller when two partially resistant lines were compared. Additionally, a histopathological study was performed at several time points (7, 14 and 30 DAI) showing the similarities between both partially resistant lines with a delay and degeneration in the formation of the syncytia in comparison to the susceptible cultivar. Females at 30 DAI in partially resistant lines showed a delay in their development in comparison to the susceptible cultivar.

Project description: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.

Project description:We aimed to identify loci under selection for virulence in the potato cyst nematode Globodera pallida. Therefore, two G. pallida populations with suspected virulence, designated AMPOP02 and AMPOP10, were used in a selection experiment on the resistant potato variety Seresta. The selection experiment started in 2015, going through one generation per year, leading to fourth-generation selection populations at the end of 2018. The experiment was conducted in large pots, with a population that was as large as possible. After each generation cysts were saved for a later pot-experiment. This pot experiment was conducted in 2019 where the replication of these G. pallida populations on a set of potato cultivars (amongst others the non-resistant cultivar Desiree and the resistant cultivar Seresta). The first priority with the resulting generation was quantification and thereafter the material resulting from the Desiree and Seresta propagation was frozen in liquid nitrogen for DNA isolation. For each generation/potato cultivar combination three replicates were conducted. In total we had therefore 60 samples. Unfortunately, after DNA isolation, we had material of sufficient quantity and quality to conduct DNA sequencing on 45 samples.
