Abstract:
The ethylene response factor VII (ERF-VII) transcription factor has been reported to be involved in multiple different stress responses. In a previous study, we showed that ERF74 and ERF75 play a redundant role in the upregulation of RESPIRATORY BURST OXIDASE HOMOLOG D (RbohD) transcription and enhance the oxygen species (ROS) burst during early stages of the stress response. Induction of stress marker genes and ROS-scavenging enzymes under various stress conditions are dependent on this ROS burst. Here, we propose an assumption that ERF71-ERF75 have different functions and act synergistically in response to stresses in Arabidopsis. ERF74 and ERF75 are involved in controlling an RbohD-dependent mechanism in response to different stresses, subsequently maintaining H2O2 homeostasis in Arabidopsis as we previously reported. ERF71 and ERF73 may have a role in supervising plant intracellular ROS homeostasis, whereas ERF72 may only act as an activator of ERF74 and ERF75 in the stress response.

Transgenic Plants
The first-ever transgenic plant was a tobacco plant developed in 1983 that showed resistance against the tobacco mosaic virus. Since then, many transgenic plants have been developed and commercialized for improving the agricultural, ornamental, and horticultural value of a crop plant. Transgenic...
