As the world’s most important staple crop, rice is highly vulnerable to anaerobic and submergence conditions that occur during flooding, particularly at the germination and vegetative stages. Anaerobic environments hinder seedling establishment during germination, while prolonged submergence during the vegetative stage impairs growth, ultimately reducing yield and grain quality. These stresses, driven by extended inundation, trigger a cascade of detrimental physiological responses and represent a major barrier to stable rice production and global food security. In this review, we examine the effects of flooding on rice growth at both the germination and vegetative stages. We further summarize recent advances in the identification of flooding-tolerant germplasm, QTL mapping, genome-wide association study, transcriptomic and proteomic analyses, and other molecular studies. Subsequently, we highlight potential cultivation and regulatory strategies, including genetic, morphological, physiological, and endogenous hormone-related approaches, aimed at enhancing tolerance to anaerobic and submergence stress. Together, these approaches underscore the promise of integrating molecular insights with agronomic practices to mitigate flooding damage and support sustainable rice production.</div></div>","PeriodicalId":56069,"journal":{"name":"Rice Science","volume":"33 2","pages":"Pages 186-202"},"PeriodicalIF":6.1,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147636698","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we demonstrate that the JmjC domain-only group member OsJMJ712 regulates heading date in rice. OsJMJ712 exhibits H3K36me3 demethylase activity at <em>Ehd1</em> and <em>RFT1</em> and represses the expression of <em>Ehd1</em>, <em>Hd3a</em>, and <em>RFT1</em>. Furthermore, loss of function of <em>OsJMJ712</em> disrupts the circadian clock, and OsLHY directly binds to the promoter of <em>OsJMJ712</em> to suppress its expression. These findings uncover that OsJMJ712 integrates histone demethylation and the circadian clock to fine-tune photoperiodic flowering in rice, providing new insights into the epigenetic control of photoperiodic flowering in crops.</div></div>","PeriodicalId":56069,"journal":{"name":"Rice Science","volume":"33 2","pages":"Pages 221-231"},"PeriodicalIF":6.1,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147636695","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This review systematically synthesizes current advances in characterizing the functional attributes and regulatory mechanisms of non-histone acetylation in rice, with a specific focus on its roles in regulating gene expression, modulating metabolic enzyme activities, and mediating stress responses. Emerging studies demonstrate that non-histone acetylation dynamically modulates transcription factors, metabolic enzymes, and other pivotal functional proteins to orchestrate essential physiological processes, including growth and development, photosynthetic efficiency, and environmental stress adaptation. Using mass spectrometry, gene editing, and related technologies, researchers have identified multiple acetyltransferases and deacetylases that regulate protein stability, subcellular localization, and protein-protein interactions. Despite these advances, challenges persist, such as the complexity of the acetylation regulatory networks and species-specific differences among cereal crops. Future investigations should integrate multi-omics approaches to elucidate the molecular mechanisms of this post-translational modification, thereby facilitating the development of targeted genetic engineering strategies for rice improvement.</div></div>","PeriodicalId":56069,"journal":{"name":"Rice Science","volume":"33 2","pages":"Pages 173-185"},"PeriodicalIF":6.1,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147636678","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although TPL/TPR proteins have been identified in various organisms, their functions in rice disease resistance remain largely unexplored. Here, we conducted a comprehensive analysis of the three rice TPL/TPR proteins, designated <em>OsTPR1</em>, <em>OsTPR2</em>, and <em>OsTPR3</em>, examining their evolutionary relationships, expression patterns, and subcellular localization, and assessing their roles in disease resistance. Phylogenetic analysis revealed that the three OsTPRs belonged to distinct evolutionary clades. Expression analysis demonstrated tissue-specific patterns and responsiveness to jasmonate (JA), with all three genes being induced upon infection with <em>Xanthomonas oryzae</em> pv. <em>oryzae</em> (<em>Xoo</em>). Consistent with their roles as transcriptional corepressors, all three OsTPRs localized to the nucleus. Disease resistance assays showed that, after inoculation with <em>Xoo</em>, lesion lengths on <em>ostpr2</em> and <em>ostpr3</em> mutants were significantly shorter than those on wild-type plants. Protein interaction assays demonstrated that OsTPR2 interacted with JA ZIM-domain protein (OsJAZ12), whose expression is also induced by <em>Xoo</em>. Furthermore, haplotype analysis of OsTPRs revealed natural variation, leading to the identification of superior allelic variants that confer improved resistance to bacterial blight without a yield penalty. Collectively, our findings provide a systematic characterization of TPL/TPR proteins in rice, highlight their potential roles in resistance to bacterial leaf blight, and identify valuable allelic resources for molecular breeding aimed at improving both disease resistance and yield.</div></div>","PeriodicalId":56069,"journal":{"name":"Rice Science","volume":"33 2","pages":"Pages 232-244"},"PeriodicalIF":6.1,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147636696","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study utilized phenotyping, ionomics, and transcriptome analysis to uncover the regulatory mechanism of Fe homeostasis in rice under different Fe concentrations and during Fe supplementation. Our results showed both Fe deficiency and excess impede rice growth, with Fe excess exerting a more severe impact, particularly on the roots. The decrease in crown roots under excessive Fe conditions likely serves as an adaptive mechanism to counteract Fe toxicity. Transcriptomic analysis identified 4652 differentially expressed genes affected by Fe stress and supplementation. When Fe is supplemented to Fe-deficient rice, there are upregulations in the expression of genes related to Fe ion concentration and Fe homeostasis at 10 min and 2 h after supplementation, respectively, along with a brief downregulation at 30 min. This indicated a protective mechanism in the roots during Fe uptake. Notably, shoots with a lack of Fe accumulation did not show re-entry of Fe after supplementation, and there was a sustained downregulation of Fe-regulated genes. This suggests that the signaling from roots to shoots influences the response of shoots to Fe supplementation in rice. The molecular changes in Fe homeostasis discovered in this study can contribute to the improvement of rice.</div></div>","PeriodicalId":56069,"journal":{"name":"Rice Science","volume":"33 2","pages":"Pages 260-276"},"PeriodicalIF":6.1,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147636699","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
