Cotton yield is determined by the number of epidermal cells that develop into lint fibers. Despite numerous studies, the genetic and molecular mechanisms controlling lint and fuzz fiber development remain elusive. Here, using the recessive naked seed or fuzzless-linted mutant (n2NSM) in combination with gene editing and complement, we identified the recessive fuzzless gene n2 encodes an MML transcription factor, GhMML3_D12. Over-expressing GhMML3_D12 in n2NSM restored fuzz fiber development. Conversely, knocking out GhMML3_D12 in wild-type cotton (J668) by CRISPR/Cas9 led to a fuzzless-linted phenotype. Interestingly, simultaneous editing of duplicated GhMML3s (GhMML3_A12 and GhMML3_D12) resulted in plants with the fiberless (fuzzless-lintless) phenotype. Detailed investigation of the seed fiber phenotype of the segregating progeny derived from a cross between a fibreless mutant of GhMML3 (#mml3s) created by gene editing and J668 not only identified progeny mimicking the natural fuzzless and fiberless mutants, but also revealed that the duplicated GhMML3_A12 and GhMML3_D12 regulate the development of fuzz and lint fibers in a dosage-dependent manner. Comparative transcriptome and single cell RNA-seq illuminated GhMML3 being the hub gene of the gene network regulating fiber initiation and early-stage elongation. The gene regulatory network revealed potential candidate genes and key regulators that may contribute to fiber initiation development. A model for lint and fuzz fiber development controlled by GhMML3 is proposed. We also revealed that GhMML3_D12 protein can directly bind to the promoters of GhHD-1 and GhMYB25, two key genes involved in fiber initiation, thereby activating their expression. The findings of this study provide fresh insights on the fundaments responsible for cotton fiber development.","PeriodicalId":52373,"journal":{"name":"Plant Communications","volume":" ","pages":"101281"},"PeriodicalIF":9.4,"publicationDate":"2025-02-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143411488","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}

Recent advancements in epitranscriptomics have shown that RNA modifications play crucial roles in diverse biological processes. Since their discovery in the 1970s, scientists have sought to decipher, identify, and elucidate the functions of these modifications across biological systems. Over the past decade, mounting evidence has demonstrated the importance of RNA modification pathways in plants, prompting significant efforts to decipher their physiological relevance. With the advent of high-resolution mapping techniques for RNA modifications and the gradual uncovering of their biological roles, our understanding of this additional layer of regulation is beginning to take shape. In this review, we summarize recent findings on the major RNA modifications identified in plants, with an emphasis on N6-methyladenosine (m6A), the most extensively studied modification. We discuss the functional significance of the effector components involved in m6A modification and its diverse roles in plant biotic interactions, including plant-virus, plant-bacterium, plant-fungus, and plant-insect relationships. Furthermore, we highlight new technological developments driving research progress in this field and outline key challenges that remain to be addressed.","PeriodicalId":52373,"journal":{"name":"Plant Communications","volume":" ","pages":"101232"},"PeriodicalIF":9.4,"publicationDate":"2025-02-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142900305","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}

With the rapid growth of the human population, the increasing pressure on rice systems for extensive and intensive farming is associated with an increase in GHG emissions that is impeding global efforts to mitigate climate change. The complex rice environment, with its genotypic variability among rice cultivars, as well as emerging farming practices and global climatic changes, are important challenges for research and development initiatives that aim to lower GHG emissions and increase crop productivity. A combination of approaches will likely be needed to effectively improve the resilience of modern rice farming. These will include a better understanding of the major drivers of emissions, different cropping practices to control the magnitude of emissions, and high yield performance through systems-level studies. The use of rice hybrids may give farmers an additive advantage, as hybrids may be better able to resist environmental stress than inbred varieties. Recent progress in the development and dissemination of hybrid rice has demonstrated a shift in the carbon footprint of rice production and is likely to lead the way in transforming rice systems to reduce GHG emissions. The application of innovative technologies such as high-throughput sequencing, gene editing, and AI can accelerate our understanding of the underlying mechanisms and critical drivers of GHG emissions from rice fields. We highlight advanced practical approaches to rice breeding and production that can support the increasing contribution of hybrid rice to global food and nutritional security while ensuring a sustainable and healthy planet.","PeriodicalId":52373,"journal":{"name":"Plant Communications","volume":"6 2","pages":"101224"},"PeriodicalIF":9.4,"publicationDate":"2025-02-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143400582","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}

Photosensitive/thermosensitive genic male sterile (P/TGMS) lines are key components of 2-line hybrid rice, and TGMS lines containing tms5 have significantly advanced 2-line hybrid rice breeding. We cloned the TMS5 gene and found that TMS5 is a tRNA cyclic phosphatase that can remove 2',3'-cyclic phosphate (cP) from cP-ΔCCA-tRNAs for efficient repair to ensure maintenance of mature tRNA levels. tms5 mutation causes increased levels of cP-ΔCCA-tRNAs and reduced levels of mature tRNAs, leading to male sterility at restrictive temperatures. However, the regulatory network of tms5-mediated TGMS remains to be clarified. Here, we demonstrate that the E3 ligase OsHel2 cooperates with TMS5 to regulate TGMS at restrictive temperatures. Consistently, both the accumulation of cP-ΔCCA-tRNAs and the reduction in mature tRNAs in the tms5 mutant are largely recovered in the tms5 oshel2-1 mutant. A lesion in OsHel2 results in partial readthrough of the stalled sequences, thereby enabling evasion of ribosome-associated protein quality control (RQC) surveillance. Our findings reveal a mechanism by which OsHel2 impedes readthrough of stalled mRNA sequences to regulate male fertility in TGMS rice, providing a paradigm for investigating how disorders in components of the RQC pathway impair cellular functions and lead to diseases or defects in other organisms.","PeriodicalId":52373,"journal":{"name":"Plant Communications","volume":" ","pages":"101192"},"PeriodicalIF":9.4,"publicationDate":"2025-02-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142632419","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}

In this review, we provide an overview of current knowledge on stress-responsive biomolecular condensates in plants, including well-defined condensates such as stress granules, processing bodies, and the nucleolus, as well as more recently discovered plant-specific condensates. By briefly referring to findings from yeast and animal studies, we discuss mechanisms by which plant condensates perceive stress signals and elicit cellular responses. Finally, we provide insights for future investigations on stress-responsive condensates in plants.
