Enrichment analysis of GO (Gene ontology) terms of the Biological Process categories (at level 2 or more). GO terms found to be significantly enriched between a/ 1^ry (TD17, SD4) and 2^ry (TD17–1, SD4–2, SD4–6, SD4–8) embryogenic lines or b/ 2^ry (SD4–8) and 3^ry (SD4–8-1, SD4–8-2, SD4–8-3) embryogenic lines of Douglas-fir. Fold change (FC) corresponds to the ratio of the number of identified hits between 2^ry and 1^ry or 3^ry and 2^ry lines, respectively
