Wheat RING E3 ubiquitin ligase TaDIS1 degrade TaSTP via the 26S proteasome pathway

Abstract

Drought stress has a great impact on wheat yields. The ubiquitin/26S proteasome system is one of the most important mechanisms employed by plants for responding to stress. E3 ubiquitin ligase is an important part of the ubiquitin/26S proteasome system. In wheat, the mechanism of E3 ubiquitin ligase TaDIS1 has not been investigated in great detail. In this study, TaSTP was identified as an interacting partner using yeast two-hybrid screening. The results obtained from bimolecular fluorescence complementation, pull-down, and co-immunoprecipitation assays also demonstrated that TaDIS1 interacts with TaSTP. In vitro ubiquitination assays showed that TaDIS1 has an E3 ubiquitin ligase activity and the results based on two TaDIS1 mutants suggested that the RING domain is essential for its E3 ubiquitin ligase activity. In addition, we used MG132 to show that TaSTP can be degraded by TaDIS1 via the 26S proteasome pathway. The transcript levels of TaSTP showed that it can also respond to different abiotic stresses, such as drought, salt, and abscisic acid treatment. RING E3 ubiquitin ligase TaDIS1 may through the posttranslational regulation of TaSTP to play an important role in drought tolerance.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
