The first draft genome assembly for Gossypium raimondii, completed in 2012, marked the beginning of global efforts in studying cotton genomics. Over the past decade, the cotton research community has continued to assemble and refine the genomes for both wild and cultivated Gossypium species. With the accumulation of de novo genome assemblies and resequencing data across virous cotton populations, significant progress has been made in uncovering the genetic basis of key agronomic traits. Achieving the goal of cotton genomics-to-breeding (G2B) will require a deeper understanding of the spatiotemporal regulatory mechanisms involved in genome information storage and expression. We advocate for a cotton ENCODE project to systematically decode the functional elements and regulatory networks within the cotton genome. Technological advances, particularly on single-cell sequencing and high-resolution spatiotemporal omics, will be essential for elucidating these regulatory mechanisms. By integrating multi-omics data, genome editing tools, and artificial intelligence, these efforts will empower the genomics-driven strategies needed for future cotton G2B breeding.","PeriodicalId":19012,"journal":{"name":"Molecular Plant","volume":" ","pages":"298-312"},"PeriodicalIF":17.1,"publicationDate":"2025-02-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143024188","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}

However, less is known about the biosynthetic mechanism of H2S in plants and its role in plant-pathogen interactions. Here, we show that H2S induces the bursts of reactive oxygen species and upregulates the expression of defense-related genes in rice. However, excessive H2S concentrations inhibit rice growth. We found that the cystathionine β-synthase OsCBSX3 regulates rice growth and resistance to bacteria pathogens, Xanthomonas oryzae pv. oryzicola (Xoc) and X. oryzae pv. oryzae (Xoo), by modulating H2S biosynthesis. OsCBSX3 exists in both oligomeric and monomeric forms in rice. Compared with wild-type OsCBSX3, an oligomerization-disrupted mutant exhibits the reduced capacity for H2S synthesis, diminished resistance to X. oryzae, and inability to localize to the chloroplast. Upon pathogen infection, rice triggers PsbO-dependent oligomerization of OsCBSX3, leading to increased H2S production and enhanced defense responses. However, excessive concentrations of H2S reduce the oligomerized form of OsCBSX3, facilitating its dissociation from PsbO, an important subunit of photosystem II, and its binding to OsTrxZ, a member of the thioredoxin family. We further demonstrated that OsTrxZ can directly convert OsCBSX3 into monomers, thereby mitigating the excessive H2S synthesis and its negative effects on rice growth and development. Overexpression of PsbO enhances rice resistance to both Xoc and Xoo, whereas overexpression of OsTrxZ exerts the opposite effect. Taken together, these findings suggest that PsbO and OsTrxZ antagonistically modulate the interconversion between oligomeric and monomeric forms of OsCBSX3, thereby balancing rice resistance and developmental processes.","PeriodicalId":19012,"journal":{"name":"Molecular Plant","volume":" ","pages":"350-365"},"PeriodicalIF":17.1,"publicationDate":"2025-02-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143008772","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}

Here, we present a phytohormone atlas resource obtained from the quantitative analysis of eight major classes of phytohormones, comprising a total of 40 hormone-related compounds, throughout the complete life cycle of wheat. In combination with transcriptome analysis, we established a wheat phytohormone metabolic regulatory network (WPMRN). Using the WPMRN dataset and Gene Ontology enrichment analysis, we swiftly characterized the function of TaLOG5-B1 in cytokinin biosynthesis. Furthermore, a detailed investigation of the WPMRN dataset uncovered transcription factor-mediated co-regulatory mechanisms among different classes of phytohormones. We focused specifically on the metabolic regulation of cytokinin and jasmonic acid, and functionally characterized the genes TaLOG3-D1 and TaAOS-D1 that are involved in the biosynthesis of these phytohormones, respectively, along with their regulatory transcription factor genes TaDOF3A and TaDOF5.6B. The functions of these genes were validated in transgenic plants, revealing their ability to co-regulate radicle length. These findings serve as a case study that highlights the utility of this resource for studying phytohormone metabolic regulatory networks in cereal crops and for gaining insights into the roles of phytohormones in enhancing agronomic traits.","PeriodicalId":19012,"journal":{"name":"Molecular Plant","volume":" ","pages":"366-382"},"PeriodicalIF":17.1,"publicationDate":"2025-02-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143008771","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}

However, the dominant root secretion governing methane emissions is not yet identified after decades of studies, even though secreted carbohydrates and organic acids have been shown to contribute to methane emissions. In this study, we discovered that fumarate and ethanol are two major rice-orchestrated secretions and play a key role in regulating methane emissions. Fumarate released in the rhizosphere is metabolized by microorganisms, supporting the growth of methanogenic archaea that produce methane as an end carbon product, while ethanol mitigates methane emissions through inhibition of methanogenic activity and growth as well as reducing fumarate synthesis in the rice root. Furthermore, we elucidated the route of fumarate metabolism in the anoxic rhizospheric zone. We found that fumarate in the rice root is produced from acetate via propionate and succinate, and when released into soil directly is oxidized to propionate before conversion via acetate into methane as the end product. The knowledge on fumarate and ethanol metabolism in rice was then used for hybrid breeding of new rice varieties with the property of low methane emission. Cultivation of these novel rice lines or employing our findings for rice cultivation managements showed up to 70% reductions in methane production from seven paddy field sites during 3 years of cultivation trials. Taken together, these findings offer great possibilities for effective mitigation of the global climatic impact of rice cultivation.","PeriodicalId":19012,"journal":{"name":"Molecular Plant","volume":"18 2","pages":"333-349"},"PeriodicalIF":17.1,"publicationDate":"2025-02-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143190011","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}
