Soybean RING-type E3 ligase GmCHYR16 ubiquitinates the GmERF71 transcription factor for degradation to negatively regulate bicarbonate stress tolerance.

Abstract excerpt

Plant AP2/ERF (APETALA2/ethylene response factor) transcription factors are key regulators of environmental stress tolerance. We previously characterized that the wild soybean ERF71 transcription factor conferred bicarbonate stress tolerance; however, the underlying mechanism still remains elusive. Here, multiple approaches were used to identify the E3 ubiquitin ligase GmCHYR16 as an interactor of GmERF71....
