Unraveling the intricate tapestry of bamboo transcription factors in abiotic stress signaling and resilience with special reference to moso bamboo family

Abstract

The abiotic stress tolerance mechanism in plants is regulated by multiple physiological, biochemical, and molecular processes; hence, omics approaches to underpin these mechanisms are essential. It is clear that transcription factors (TFs) are one of the fundamental molecular switches that play a crucial role in modulating, regulating, and orchestrating plants in response to various climatic vagaries. Several reports are available now, focusing on understanding the roles of TFs, including those in Poaceae family in regulating different biological processes and stress responses. However, research on bamboo TFs' regulatory role in providing abiotic stress tolerance is limited. Hence the present review offers innovative insights into unraveling the molecular regulation of known family of TFs in different species of bamboo which have been identified as regulators of transcript abundance in numerous genes responsive to various abiotic stresses. Additionally, this review highlights recent discoveries concerning bamboo TFs, encompassing their classification, promoter analysis and functional dynamics in response to different abiotic stresses. Attempt has also been made to delve into the molecular interplay and cross-talk among these TFs during abiotic stresses, thus proposing potential strategies for enhancing the intricate regulatory networks involved in the adaptive responses of bamboo species.
