Short-term low PPFD differentially affects protein profiles and terpenoid metabolism, and LED spectra drive clone-specific responses in <i>Artemisia annua:</i> implications for PFAL-based genotypic selection

Light is a key abiotic factor regulating plant-environment interactions; its short-term effects on terpenoid biosynthesis in Artemisia annua remain unclear under controlled environments. This study investigated how short-term variations in light intensity and spectrum are associated with t
