520	3		_aThe basic leucine zipper (bZIP)protein transcription factors are known to modulate development, plant growth, metabolic response, and resistance to several biotic and abiotic stressors and have been widely studied in the model plant Arabidopsis thaliana. However, no comprehensive information about the bZIP transcription factor family in Artemisia annua has been explored to date. In this genome-wide study, we identified 61 bZIP TFs after removing false positives and incomplete sequences from Artemisia annua. Seven highly expressed homolog AabZIP TF genes under UV-B and differential light conditions in different tissues were identified from the publicly available microarray dataset as having their cis-regulatory elements involved in, flavonoids biosynthesis, seed-specific gene regulation, stress responses, and metabolic regulation. In-silico analysis and electrophoretic mobility shift assay (EMSA)confirmed the interaction of AabZIP19 TF over the AaPAL1 promoter in order to regulate the phenolics and flavonoid biosynthesis via the phenylpropanoid pathway. Further, RT-PCR analysis has been carried out to validate the transcript levels of selected AabZIP genes under white light, red light, blue light (45 min), and UV-B exposure (12 and 24 h). These genes have their highest expression levels under UV-B and blue light exposure, in contrast with white light. Therefore, the detection of ROS through staining confirms the accumulation of superoxide radicals and H2O2, and in addition to reducing ROS accumulation under UV-B and blue light irradiation, total phenols and flavonoids are significantly enhanced. This study laid the groundwork for deciphering the possible role of AabZIP TFs under different light stress-responsive conditions and in the regulation of secondary metabolism.
