Nitrogen (N) is a crucial plant macronutrient, but the production of synthetic N fertilizer and its leakage into aquatic systems represent sources of environmental damage. To reduce the usage of synthetic fertilizers, current studies addressed innovative approaches to develop “N-self-fertilizing” crops that can utilize atmospheric nitrogen through enhanced interaction with the root microbiome. In this review we discuss recently obtained knowledge about the role of root hairs and their functions in root exudate secretion for plant-microbiome interactions. Recent studies have shown the beneficial impact of root hairs and exudate secretion on the recruitment of N2 fixing bacteria. Root hair plays a crucial role in shaping the rhizosphere, and first insights into the biological processes that underpin root hair formation and function in relation to microbiome interaction were gained. We summarize to which extent this knowledge can be applied to develop cereals with an enhanced ability to benefit from N2 fixing bacteria. Finally, we describe non-destructive methods and their limitations to study root hair growth directly in the field under natural growth conditions.","PeriodicalId":474806,"journal":{"name":"Frontiers in Plant Physiology","volume":"52 20","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138952430","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This compartment within the thylakoid membranes of chloroplasts was originally perceived as “empty”, only providing a site for proton accumulation to support ATP formation. Instead, recent investigations have revealed that the lumen houses a specific set of proteins each with potentially critical roles. The structure of this compartment has been shown to be dynamic, with changes in size and organization influenced by light exposure, impacting protein mobility and function. Noteworthy, some of the lumen proteins are permanently or transiently in contact with protein complexes located in the thylakoid membrane, such as PSII (PsbP-like and PsbQ-like proteins) cytochrome b6f, and PSI. Meanwhile, other lumen proteins seems to be more “independent” such as proteases, immunophilins, stress-related proteins, pentapeptide repeat proteins, and many others with unknown functions. All these proteins play crucial roles in maintaining photosynthetic machinery, adapting to environmental stress, and regulating cellular processes. Understanding the lumen’s function is vital as it holds promise for uncovering novel regulatory interactions and signaling pathways within the chloroplast.","PeriodicalId":474806,"journal":{"name":"Frontiers in Plant Physiology","volume":"9 6‐7","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138978687","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These mechanisms are the result of a long evolutionary history that has led to sophisticated regulatory mechanisms involving multiple levels of regulators. MicroRNAs (miRNAs) are a class of small regulatory molecules that play a pivotal role in regulatory networks by negatively controlling target genes. Since miRNA very first identification twenty years ago, they have attracted much interest for their role as essential regulators of plant development. In this review, we propose a comprehensive and critical analysis of the importance of miRNAs during plant development and reproduction. We begin by presenting the current understanding of miRNAs’ evolutionary history, biogenesis, mode of action, position in regulatory networks, and their potential as mobile molecules, exploring how these aspects contribute to their functions in plant development and reproduction. Then, we explore the genetic strategies employed to effectively analyze their roles, with an emphasis on recent advancements resulting from genome editing techniques. Next, we focus on miRNA contributions to four crucial processes: growth, organ patterning and identity, life cycle progression and reproduction. Through this analysis, the importance of miRNAs during plant development and reproduction emerges, which we finally discuss in light of the current view miRNAs’ roles during animal development.","PeriodicalId":474806,"journal":{"name":"Frontiers in Plant Physiology","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135901556","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
