Plants encounter a wide range of abiotic and biotic stresses throughout their life cycle, necessitating precise regulation of gene expression for adaptation and survival. Gene expression is primarily controlled by specific genomic sequences known as cis-regulatory elements (CREs), which serve as binding sites for transcription factors and cis-regulatory modules (CRMs), which are clusters of CREs that include promoters, enhancers, silencers, and insulators. CRM?s are stretches of DNA, usually 100-1000 DNA base pairs in length, where a number of transcription factors can bind and regulate expression of nearby genes and regulate their transcription rates. Cis-regulatory elements (CREs) are short DNA motifs in gene promoters that act as molecular switches, controlling stress-responsive gene expression through transcription factor (TF) binding. In abiotic stress, pathways such as ABAdependent (AREB/ABF) and ABA-independent (DREB/CBF, NAC and MYB/MYC) regulate gene activation, as exemplified by the 116 to 2 bp promoter region of HRE2 in Arabidopsis bound by HAT22/ABIG1. Under biotic stress, CREs coordinate defence via., salicylic acid (SA), masonic acid (JA), and ethylene (ET) signaling, with NPR1 interacting with TGA TFs to activate pathogenesis-related genes and systemic acquired resistance.
