*4.4. Growth Conditions and Sampling*

*PR1* and *PR10* expression of each line, *Dar Gazi-wt*, *Dar Gazi-phyB,* and *Dar Gazi-cry1*, was evaluated in plants grown in vitro according to Abdollahi et al. (2004) [2] at 22 ◦C and under a 40 µmol m−<sup>2</sup> s <sup>−</sup><sup>1</sup> WL. For the light experiments, plants were then placed under different light conditions: WL (100 µmol m−<sup>2</sup> s −1 ), RL (25 µmol m−<sup>2</sup> s −1 ), FRL (25 µmol m−<sup>2</sup> s −1 ) or BL (25 µmol m−<sup>2</sup> s −1 ) obtained using specific LED lamps. Light quality and quantity were measured with an EPP 2000 Fiber Optic Spectrometer (StellarNet Inc., Tampa, Florida, USA). Plants were harvested as reported in supplemented Figures S1–S3.
