A key component of these networks is gene regulation at multiple levels, including precursor messenger RNA (pre-mRNA) splicing, which shapes the transcriptome and proteome landscapes. Through the precise action of the spliceosome complex, noncoding introns are removed and coding exons are joined to produce spliced RNA transcripts. While constitutive splicing always generates the same messenger RNA (mRNA), alternative splicing (AS) produces multiple mRNA isoforms from a single pre-mRNA, enriching proteome diversity. Remarkably, 80% of multiexon genes in plants generate multiple isoforms, underscoring the importance of AS in shaping plant development and responses to abiotic and biotic stresses. Recent advances in CRISPR-Cas genome and transcriptome editing technologies offer revolutionary tools to dissect AS regulation at molecular levels, unveiling the functional significance of specific isoforms. In this review, we explore the intricate mechanisms of pre-mRNA splicing and AS in plants, with a focus on stress responses. Additionally, we examine how leveraging AS insights can unlock new opportunities to engineer stress-resilient crops, paving the way for sustainable agriculture in the face of global environmental challenges.","PeriodicalId":8335,"journal":{"name":"Annual review of plant biology","volume":" ","pages":""},"PeriodicalIF":21.3,"publicationDate":"2025-02-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143424564","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite their conserved function, plant centromeres show rapid sequence evolution within and between species and a range of monocentric, holocentric, and polymetacentric architectures, which vary in kinetochore numbers and spacing. Plant centromeres are commonly composed of tandem satellite repeat arrays, which are invaded by specific families of centrophilic retrotransposons, whereas in some species the entire centromere is composed of such retrotransposons. We review the diversity of plant centrophilic retrotransposons and their mechanisms of integration, together with how epigenetic information and small RNAs control their proliferation. We discuss models for rapid centromere sequence evolution and speculate on the roles that centrophilic retrotransposons may play in centromere dynamics. We focus on plants but draw comparisons with animal and fungal centromeric transposons to highlight conserved and divergent themes across the eukaryotes.","PeriodicalId":8335,"journal":{"name":"Annual review of plant biology","volume":" ","pages":""},"PeriodicalIF":21.3,"publicationDate":"2025-02-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143424572","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Posttranslational modifications of histone tails have emerged as important regulatory mechanisms for diverse biological processes, including genome organization, gene expression, transposable element suppression, development, and environmental responses. This field is expanding rapidly with the development of new technologies and growing interest from both the basic and translational research communities. The past two decades have witnessed tremendous progress in our understanding of the complex, multilayered regulation and actions of histone modifications in plants. This review summarizes the characteristics, localization, and molecular functions of histone modifications with an emphasis on the well-studied marks in Arabidopsis. We further discuss their functions in developmental transitions and environmental responses as well as their contributions to epigenomic diversity and plasticity. By highlighting the functions and fundamental mechanisms of epigenetic modifications in model plants, this review underscores the potential to harness epigenetic regulation for agricultural improvement.","PeriodicalId":8335,"journal":{"name":"Annual review of plant biology","volume":" ","pages":""},"PeriodicalIF":21.3,"publicationDate":"2025-02-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143424577","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

They are some of the most dynamic components of plant cell walls, and pectin remodeling and degradation by pectin-modifying enzymes can drive developmental programming via physical effects on the cell wall and the generation of oligosaccharides that can act as signaling ligands. Here, we introduce pectin structure and synthesis and discuss pectin functions in plants. We highlight recent advances in understanding the structure-function relationships of pectin-modifying enzymes and their products and how these advances point toward new approaches to bridging key knowledge gaps and manipulating pectin dynamics to control plant development. Finally, we discuss how a deeper understanding of pectin dynamics might enable innovations in agronomy and biotechnology, unlocking new benefits from these ubiquitous but complex polysaccharides.","PeriodicalId":8335,"journal":{"name":"Annual review of plant biology","volume":" ","pages":""},"PeriodicalIF":21.3,"publicationDate":"2025-01-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143021641","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Cell wall thickenings are present in many different root cell types. They come in a variety of simple and more complex structures with varying composition of lignin and suberin and can change in response to environmental stressors. The majority of these root cell wall thickenings and cell types that contain them are absent in the model plant Arabidopsis thaliana despite being present in most plant species. As a result, we know very little regarding their developmental control and function. Increasing evidence suggests that these structures are critical for responding to and facilitating adaptation to a wide array of stresses that a plant root experiences. These structures function in blocking apoplastic transport, oxygen, and water loss and enhancing root penetrative strength. In this review, we describe the most common types of cell wall thickenings in the outer cell types of plant roots-the velamen, exodermal thickenings, the sclerenchyma, and phi thickenings. Their cell-type dependency, morphology, composition, environmental responsiveness, and genetic control in vascular plants are discussed, as well as their potential to generate more stress-resilient roots in the face of a changing climate.","PeriodicalId":8335,"journal":{"name":"Annual review of plant biology","volume":" ","pages":""},"PeriodicalIF":21.3,"publicationDate":"2025-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142920350","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
