| Abstract |
A rice gene (OsSIRP2) encoding the RING Ub E3 ligase was highly induced under salinity stress and physically interacted with a transketolase (OsTKL1). Overexpression of OsSIRP2 conferred salinity and osmotic stress tolerance in plants. The RING E3 ligases play a vital role in post transitional modification through ubiquitination-mediated protein degradation that mediate plants responses during abiotic stresses and signal transduction. In this study, we report an Oryza sativa salt induced Really Interesting New Gene (RING) finger protein 2 gene (OsSIRP2) and elucidate its role under salinity and osmotic stress. The transcript levels of OsSIRP2 in rice leaves were induced in response to different abiotic stresses, such as salt, drought, heat, and abscisic acid (ABA) exposure. In vitro ubiquitination revealed that the OsSIRP2 protein formed poly-ubiquitin products, whereas a single amino acid substitution in OsSIRP2 (OsSIRP2C149A) in the RING domain did not form ubiquitinated substrates, supporting the hypothesis that E3 ligase activity requires the functional RING domain. Using the yeast two-hybrid (Y2H) assay, O. sativa transketolase 1 (OsTKL1) was identified as an interacting partner. OsSIRP2 was localized in the nucleus, whereas its interacting partner (OsTKL1) was localized in the cytosol and plastids in the rice protoplasts. Fluorescence signals between OsSIRP2 and OsTKL1 were observed in the cytosol. The pull-down assay confirmed the physical interaction between OsSIRP2 and OsTKL1. In vitro ubiquitination assay and in vitro protein degradation assay revealed that OsSIRP2 ubiquitinates OsTKL1 and enhances the degradation of OsTKL1 through the 26S proteasomal pathway. Heterogeneous overexpression of OsSIRP2 resulted in conferring tolerance against salinity and osmotic stress. Overall, our findings suggest that OsSIRP2 may be associated with plant responses to abiotic stresses and act as a positive regulator of salt and osmotic stress tolerance. |

Attention Score in Context
This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 26 January 2018.
All research outputs
#15,489,831
of 23,018,998 outputs
Outputs from Planta
#1,880
of 2,738 outputs
Outputs of similar age
#269,358
of 441,975 outputs
Outputs of similar age from Planta
#13
of 33 outputs
Altmetric has tracked 23,018,998 research outputs across all sources so far. This one is in the 22nd percentile – i.e., 22% of other outputs scored the same or lower than it.
So far Altmetric has tracked 2,738 research outputs from this source. They receive a mean Attention Score of 3.3. This one is in the 24th percentile – i.e., 24% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 441,975 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 30th percentile – i.e., 30% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 33 others from the same source and published within six weeks on either side of this one. This one is in the 39th percentile – i.e., 39% of its contemporaries scored the same or lower than it.
