Araucaria angustifolia is a critically endangered species and its distribution can be affected by an increase in temperature. In this study, we evaluated the effects of heat stress (30°C) on Araucaria angustifolia cell lines responsive (SE1) and non-responsive (SE6) to the development of somatic embryos. The viability of both cell lines was reduced by heat stress and mitochondria were the organelles most affected.

Our previous work described that B16-F10 cells enter in a quiescent state as a protective mechanism against damage generated by reactive oxygen species (ROS) during melanogenesis stimulation. Our present results show that QSOX activity was two-fold higher in cells with stimulated melanogenesis when compared to control cells.

- The text discusses the critically endangered status of certain conifer species and highlights the challenges in their conservation and propagation methods, particularly somatic embryogenesis (SE) and cryopreservation.
- It examines how the efficiency of SE is affected by the genotype's response to growth stimuli, categorizing cell lines as responsive (SE1) and non-responsive (SE6) to somatic embryo development.
- The study found significant differences in antioxidant enzyme activities and mitochondrial functions between the two cell types, suggesting these factors are vital for the maturation process of embryogenic cells.
