show Abstracthide AbstractTo characterize plant growth in net zero energy greenhouse models with semi-transparent organic solar cell (OSC) filter roofs, RNA was extracted from red oak leaf lettuce leaves grown under 3 OPV filters (FTAZ:IT-M, PTB7-Th:IEICO-4F, FTAZ:PCBM) an clear and shaded glass controls. 2 light intensity experiments were used. PPPFD Controlled (PC) treatments had a constant light intensity and different light spectra created by the filters. Height Controlled (HC) treatments varied in both light intensity and spectra, according to the light transmission of each filter. When light intensity was controlled, plants grown under FTAZ:IT-M had a DEG profile distinct from plants grown under the other 2 filters. Key genes were up or down-regulated that indicate changes in anthocyanin accumulation, nitrogen metabolism and pest defense. Overall design: Leaf tissue mRNA sampled from 4 individual plants grown under 1 of 8 light spectra and intensity conditions The Sample title and characteristics were updated on June 14, 2022.
