Expression of stress-related genes RAD51, KU80, ATG5, ATG8 and CAT (mRNA copy number) in Scots pine embryogenic cell masses representing different cell lines during the induction of SE. The SE lines originated from the mother trees K818 (gray lines (green lines online)) and K884 (black lines). From the young SE lines, two (solid lines) out of six produced embryos and four did not (dashed lines). The old SE lines (K818-9 and K884-10) are marked with small dash (with lighter colors online). Every observation point represents an arithmetic mean  ±  standard error from three Q-RT-PCR analyses.
