Deciphering the role of WRKY transcription factors in plant resilience to alkaline salt stress

The WRKY gene family consists of unique transcription factors (TFs) found exclusively in plants. These TFs play a crucial role in regulating how plants respond to various abiotic stresses, such as saline-alkaline conditions, temperature fluctuations, drought, UV radiation and others. Scientists have been progressively studying the roles and mechanisms of WRKY in several plant species, including both model plants and essential agricultural crops. This study focus has emerged due to the understanding that alkaline and saline soil stressors considerably impede global agricultural productivity. Multiple research efforts have underscored the significant biological functions of WRKY TFs in assisting plants in coping with various abiotic challenges, particularly in enhancing their ability to withstand alkaline-salt stress. This review aims to investigate the structural capabilities of WRKY TFs and their impact on plant responses to alkaline and salt stresses. Additionally, it seeks to elucidate the role of these TFs in alleviating diverse abiotic and biotic stressors. The objective of this review study is to provide comprehensive insights into the current state of the field and the importance of WRKY TFs in regulating plant responses to salt and alkaline stress.
