Abstract

Edible oils are one of the essential commodities in the food basket of the people. Maintaining oil oxidative stability to extend shelf life and enhance the quality and nutritional value of the product is particularly important. This is achieved by increasing the content of natural Antioxidants such as Tocopherols as additives or by modifying their content and composition in oilseed plant through metabolic engineering of key enzymes or Transcription factors involved in tocopherol biosynthesis. The present study aimed to identify Transcription factors corresponding to conserved motifs in the promoter regions of VTE4 and its orthologous genes as a limiting bottleneck in tocopherol biosynthesis using bioinformatics tools. The results showed that the Transcription factors mainly belonged to hemodomain-like (24. 4%), bZIP (17. 1%), SANT / MYB (14. 6%), K-box (12. 2%), MADS-box (12. 2%) and MYB (12. 2%) families. Furthermore, functional analysis of Transcription factors indicated a significant interaction between response to abiotic stresses, hormone signaling pathways, especially abscisic acid and gibberellic acid, and the tocopherol biosynthesis pathway. On the other hand, the prominent role of light stimuli, in particular, red and infrared light, and Light signaling pathway components was observed in the induction of expression of VTE4’ s Transcription factors.
