Fig 4. Identification of Pratylenchus penetrans transcripts significantly upregulated in planta.

Differential expression analysis was carried out on all transcripts in the P. penetrans transcriptome. Those differentially expressed at a significant level (FDR p < 0.001, min fold change 2) were grouped into various expression clusters. Here, 5 clusters, each with variations in magnitude of the same biologically relevant expression profile contains a total of 58 trinity components. The average for each cluster and each life stage is indicated by black bars. Of these transcripts upregulated, 31% encode proteins with putative signal peptides for secretion; a 3.5 fold enrichment over the rest of the transcriptome.
