“…Moreover, in this module, genes involved in the ubiquitination process, OsUBC13 and OsUCH2 , were reported. Protein degradation by SUMOylation, the post-translational process via Small Ubiquitin-like Modifiers (SUMO) has been reported to regulate the rapid defense against environmental stresses, including drought, cold, heat, nutrient deficiency, and salt stresses ( Ghimire et al, 2020 ). OsUBC13 belongs to UBC class I and is induced by drought and salt stress ( Zhiguo et al, 2015 ).…”

Salinity is an important environmental factor causing a negative effect on rice production. To prevent salinity effects on rice yields, genetic diversity concerning salt tolerance must be evaluated. In this study, we investigated the salinity responses of rice (Oryza sativa) to determine the critical genes. The transcriptomes of ‘Luang Pratahn’ rice, a local Thai rice variety with high salt tolerance, were used as a model for analyzing and identifying the key genes responsible for salt-stress tolerance. Based on 3' Tag-Seq data from the time course of salt-stress treatment, weighted gene co-expression network analysis was used to identify key genes in gene modules. We obtained 1,386 significantly differentially expressed genes in eight modules. Among them, six modules indicated a significant correlation within 6, 12, or 48h after salt stress. Functional and pathway enrichment analysis was performed on the co-expressed genes of interesting modules to reveal which genes were mainly enriched within important functions for salt-stress responses. To identify the key genes in salt-stress responses, we considered the two-state co-expression networks, normal growth conditions, and salt stress to investigate which genes were less important in a normal situation but gained more impact under stress. We identified key genes for the response to biotic and abiotic stimuli and tolerance to salt stress. Thus, these novel genes may play important roles in salinity tolerance and serve as potential biomarkers to improve salt tolerance cultivars.

“…SUMOylation is the post-translational modification of proteins which covalently conjugates Small Ubiquitin-related Modifier (SUMO; ~100 amino acids) to a lysine residue in the target substrate [92]. SUMOylation is highly dynamic and reversible and post-translational regulation by SUMOylation plays essential roles in developmental processes and stress responses in plants [93]. SUMOylation regulates protein activity by inducing subcellular redistribution, modulating protein-protein interactions, competing with other post-translational modifications, promoting protein conformational changes or target protein for ubiquitination and subsequent degradation by the proteasome [92,94].…”

The molecular components of the circadian system possess the interesting feature of acting together to create a self-sustaining oscillator, while at the same time acting individually, and in complexes, to confer phase-specific circadian control over a wide range of physiological and developmental outputs. This means that many circadian oscillator proteins are simultaneously also part of the circadian output pathway. Most studies have focused on transcriptional control of circadian rhythms, but work in plants and metazoans has shown the importance of post-transcriptional and post-translational processes within the circadian system. Here we highlight recent work describing post-translational mechanisms that impact both the function of the oscillator and the clock-controlled outputs.

“…SUMO can also act as a substrate for SUMO E3 ligases to promote SUMO chain formation. For example, PIAL1/2 were shown to extend SUMO chains (Tomanov et al, 2014) and are thus described either as E3 ligases (Han et al, 2016;Benlloch and Lois, 2018) or E4 ligases (Tomanov et al, 2014;Morrell and Sadanandom, 2019;Ghimire et al, 2020). Mechanistically, chain formation could be due to the presence of SIMs that contact SUMO as a substrate.…”

Protein modification by the small ubiquitin-like modifier (SUMO) plays an important role in multiple plant processes, including growth, development, and the response to abiotic stresses. Mechanistically, SUMOylation is a sequential multi-enzymatic process where SUMO E3 ligases accelerate SUMO conjugation while also influencing target identity and interactions. This review explores the biological functions of plant SUMO E3 ligases [SAP AND MIZ1 DOMAIN-CONTAINING LIGASE (SIZs), METHYL METHANESULFONATE-SENSITIVITY PROTEIN 21 (MMS21s), and PROTEIN INHIBITOR OF ACTIVATED STAT-LIKE (PIALs)] in relation to their molecular activities and domains. We also explore the sub-cellular localization of SUMO E3 ligases and review evidence suggesting a connection between certain SUMO E3 ligases and DNA that contributes to gene expression regulation.
