Abstract:
:Using a complementary (c)DNA-amplified fragment length polymorphism (AFLP) approach, we investigated differential gene expression linked to resistance mechanisms during the incompatible potato - Globodera pallida interaction. Expression was compared between a resistant and a susceptible potato clone, inoculated or not inoculated with G. pallida. These clones were issued from a cross between the resistant Solanum sparsipilum spl329.18 accession and the susceptible dihaploid S. tuberosum Caspar H3, and carried, respectively, resistant and susceptible alleles at the resistance quantitative trait loci (QTLs). Analysis was done on root fragments picked up at 4 time points, during a period of 6 days after infection, from penetration of the nematode in the root to degradation of the feeding site in resistant plants. A total of 2560 transcript-derived fragments (TDFs) were analyzed, resulting in the detection of 46 TDFs that were up- or downregulated. The number of TDFs that were up- or downregulated increased with time after inoculation. The majority of TDFs were upregulated at only 1 or 2 time points in response to infection. After isolation and sequencing of the TDFs of interest, a subset of 36 sequences were identified, among which 22 matched plant sequences and 2 matched nematode sequences. Some of the TDFs that matched plant genes showed clear homologies to genes involved in cell-cycle regulation, transcription regulation, resistance downstream signalling pathways, and defense mechanisms. Other sequences with homologies to plant genes of unknown function or without any significant similarity to known proteins were also found. Although not exhaustive, these results represent the most extensive list of genes with altered RNA levels after the incompatible G. pallida-potato interaction that has been published to date. The function of these genes could provide insight into resistance or plant defense mechanisms during incompatible potato-cyst nematode interactions.
