CAREs play an important role in plant stress tolerance by interacting with transcription factors and controlling the expression of many stress related potential genes. Recognition of promoters and their regulatory elements is one of the crucial challenges in biotechnology. In this study, we examine cis acting regulatory element in 5’ upstream regions (~1 kb) of Asc-Glu pathway genes such as SOD, APX, MDHAR, DHAR, and GR. The evolutionary relationships amongst these sequences were deciphered using MEGA v. 6.0. The promoter region these genes contain various cis acting regulatory elements such as MBS, DRE/C repeat, W box, HSE, TCA element, LTR, ABRE box, ARE box, Wun and DRE that have significant role in stress tolerance Asc-Glu promoter sequences analysis revealed their specific responsiveness or overlapping in various environment stress and significantly contribute toward plant growth and development.
