RNA helicases are omnipresent plant proteins across all kingdoms and have been demonstrated to play an essential role in all cellular processes involving nucleic acids. Currently, these proteins emerged as a new tool for plant molecular biologists to modulate plant stress responses. Here, we review the crucial role of RNA helicases triggered by biotic, abiotic, and multiple stress conditions. In this review, the emphasis has been given on the role of these proteins upon viral stress. Further, we have explored RNA helicase mediated regulation of RNA metabolism, starting from ribosome biogenesis to its decay upon stress induction. We also highlighted the cross-talk between RNA helicase, phytohormones, and ROS. Different overexpression and transgenic studies have been provided in the text to indicate the stress tolerance abilities of these proteins. Copyright © 2020 Elsevier B.V. All rights reserved.
