SUMO E3 ligase SIZ1 connects sumoylation and reactive oxygen species homeostasis processes in Arabidopsis. PLANT PHYSIOLOGY 2022; 189:934-954. [PMID: 35238389 PMCID: PMC9157161 DOI: 10.1093/plphys/kiac085] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/16/2021] [Accepted: 01/26/2022] [Indexed: 06/14/2023]
Abstract
The ubiquitin-like modifying peptide SMALL UBIQUITIN-LIKE MODIFIER (SUMO) has become a known modulator of the plant response to multiple environmental stimuli. A common feature of many of these external stresses is the production of reactive oxygen species (ROS). Taking into account that SUMO conjugates rapidly accumulate in response to an external oxidative stimulus, it is likely that ROS and sumoylation converge at the molecular and regulatory levels. In this study, we explored the SUMO-ROS relationship, using as a model the Arabidopsis (Arabidopsis thaliana) null mutant of the major SUMO-conjugation enhancer, the E3 ligase SAP AND MIZ 1 (SIZ1). We showed that SIZ1 is involved in SUMO conjugate increase when primed with both exogenous and endogenous ROS. In siz1, seedlings were sensitive to oxidative stress imposition, and mutants accumulated different ROS throughout development. We demonstrated that the deregulation in hydrogen peroxide and superoxide homeostasis, but not of singlet O2 (1O2), was partially due to SA accumulation in siz1. Furthermore, transcriptomic analysis highlighted a transcriptional signature that implicated siz1 with 1O2 homeostasis. Subsequently, we observed that siz1 displayed chloroplast morphological defects and altered energy dissipation activity and established a link between the chlorophyll precursor protochlorophyllide and deregulation of PROTOCHLOROPHYLLIDE OXIDOREDUCTASE A (PORA), which is known to drive overproduction of 1O2. Ultimately, network analysis uncovered known and additional associations between transcriptional control of PORA and SIZ1-dependent sumoylation. Our study connects sumoylation, and specifically SIZ1, to the control of chloroplast functions and places sumoylation as a molecular mechanism involved in ROS homeostatic and signaling events.

Abstract
The increasing dynamic functions of post-translational modifications (PTMs) within protein molecules present outstanding challenges for plant biology even at this present day. Protein PTMs are among the first and fastest plant responses to changes in the environment, indicating that the mechanisms and dynamics of PTMs are an essential area of plant biology. Besides being key players in signaling, PTMs play vital roles in gene expression, gene, and protein localization, protein stability and interactions, as well as enzyme kinetics. In this review, we take a broader but concise approach to capture the current state of events in the field of plant PTMs. We discuss protein modifications including citrullination, glycosylation, phosphorylation, oxidation and disulfide bridges, N-terminal, SUMOylation, and ubiquitination. Further, we outline the complexity of studying PTMs in relation to compartmentalization and function. We conclude by challenging the proteomics community to engage in holistic approaches towards identification and characterizing multiple PTMs on the same protein, their interaction, and mechanism of regulation to bring a deeper understanding of protein function and regulation in plants.

Abstract
Plants are constantly confronted by a multitude of biotic stresses involving a myriad of pathogens. In crops, pathogen infections result in significant agronomical losses worldwide posing a threat to food security. In order to enter plant tissues and establish a successful infection, phytopathogens have to surpass several physical, and chemical defense barriers. In recent years, post-translational modification (PTM) mechanisms have emerged as key players in plant defense against pathogens. PTMs allow a highly dynamic and rapid response in front of external challenges, increasing the complexity and precision of cellular responses. In this review, we focus on the role of SUMO conjugation (SUMOylation) in plant immunity against fungi, bacteria, and viruses. In plants, SUMO regulates multiple biological processes, ranging from development to responses arising from environmental challenges. During pathogen attack, SUMO not only modulates the activity of plant defense components, but also serves as a target of pathogen effectors, highlighting its broad role in plant immunity. Here, we summarize known pathogenic strategies targeting plant SUMOylation and, the plant SUMO conjugates involved in host-pathogen interactions. We also provide a catalog of candidate SUMO conjugates according to their role in defense responses. Finally, we discuss the complex role of SUMO in plant defense, focusing on key biological and experimental aspects that contribute to some controversial conclusions, and the opportunities for improving agricultural productivity by engineering SUMOylation in crop species.

Abstract
Post-translational modification of cellular proteins by sumoylation plays a vital role in stress responses of plants. However, the mechanisms underlying the sumoylation’s involvement in stress responses in crop species remain largely unknown. Herein, a maize class-I SUMO conjugating enzyme gene (ZmSCE1d) was identified, whose expression was upregulated upon drought stress. Over-expression of ZmSCE1d in transgenic Arabidopsis plants increased SUMO conjugates and improved drought tolerance. The ZmSCE1d-transgenic plants showed higher antioxidant enzyme activities, but lower reactive oxygen species and lipid peroxidation upon drought stress. Furthermore, transcripts of several drought-responsive genes were significantly elevated, as revealed by qPCR in the transgenic lines. Taken together, these data have demonstrated that ZmSCE1d overexpression improved drought tolerance likely by regulating sumoylation levels, antioxidant capability, and drought-responsive gene expression in transgenic plants. This study may facilitate our understanding of the mechanisms underlying SCE-mediated sumoylation under drought stress and accelerate genetic improvement of crop plants tolerant to drought stress by manipulating the SUMO system.

Structural insights into SUMO E1–E2 interactions in Arabidopsis uncovers a distinctive platform for securing SUMO conjugation specificity across evolution. Biochem J 2019; 476:2127-2139.

Abstract
Abstract
SUMOylation of proteins involves the concerted action of the E1-activating enzyme, E2-conjugating enzyme and E3-ligases. An essential discrimination step in the SUMOylation pathway corresponds to the initial interaction between E1 ubiquitin-fold domain (UFD) and E2 enzymes. Although E2 orthologs possess high sequence identity, the E2 binding region of the UFD domains has diverged across evolution. Moreover, in reciprocal in vitro conjugation reactions Arabidopsis E1 and E2 SCE1 fail to interact efficiently with cognate human E2 Ubc9 and E1 partners, respectively. To gain more insights into the properties of this interface in evolutionary distant organisms, we solved the crystal structure of SUMO E2 SCE1 and its complex with E1 UFD in Arabidopsis. In addition to a few common structural determinants, the interface between the E1 UFD and E2 in Arabidopsis is distinct compared with human and yeast, in particular by the presence of a longer α-helix in the Arabidopsis UFD domain. Despite the variability of E1 UFD domains in these surfaces, they establish specific interactions with highly conserved surfaces of their cognate E2 enzymes. Functional analysis of the different E2 interface residues between human and Arabidopsis revealed Val37 (Met36 in human), as a determinant that provides specificity in the E1–E2 recognition in plants.
