In plants, acquired thermotolerance has been studied mainly at the transcriptional level, including recent descriptions of sophisticated regulatory circuits that are essential for this learning capacity. Here, we tested the involvement of polysome-related processes [translation and cotranslational mRNA decay (CTRD)] in Arabidopsis (Arabidopsis thaliana) thermotolerance using two heat stress regimes with and without a priming event. We found that priming is essential to restore the general translational potential of plants shortly after acute heat stress. We observed that mRNAs not involved in heat stress suffered from reduced translation efficiency at high temperatures, whereas heat stress-related mRNAs were translated more efficiently under the same condition. We also showed that the induction of the unfolded protein response (UPR) pathway in acute heat stress is favored by a previous priming event and that, in the absence of priming, ER-translated mRNAs become preferential targets of CTRD. Finally, we present evidence that CTRD can specifically regulate more than a thousand genes during heat stress and should be considered as an independent gene regulatory mechanism.","PeriodicalId":20101,"journal":{"name":"Plant Physiology","volume":" ","pages":""},"PeriodicalIF":6.5,"publicationDate":"2025-02-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142838576","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 highlight select technological innovations in the study of root development, with a focus on the transformative impact of single-cell gene expression analysis. We provide a high-level overview of recent advancements, illustrating how single-cell RNA sequencing (scRNA-seq) has become a pivotal tool in plant biology. scRNA-seq has revolutionized root biology by enabling detailed, cell-specific analysis of gene expression. This has allowed researchers to create comprehensive root atlases, predict cell development, and map gene regulatory networks (GRNs) with unprecedented precision. Complementary technologies, such as multimodal profiling and bioinformatics, further enrich our understanding of cellular dynamics and gene interactions. Innovations in imaging and modeling, combined with genetic tools like CRISPR, continue to deepen our knowledge of root formation and function. Moreover, the integration of these technologies with advanced biosensors and microfluidic devices has advanced our ability to study plant-microbe interactions and phytohormone signaling at high resolution. These tools collectively provide a more comprehensive understanding of root system architecture and its regulation by environmental factors. As these technologies evolve, they promise to drive further breakthroughs in plant science, with substantial implications for agriculture and sustainability.","PeriodicalId":20101,"journal":{"name":"Plant Physiology","volume":" ","pages":""},"PeriodicalIF":6.5,"publicationDate":"2025-02-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142838572","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 precise roles of hexose/H+ symporters in postphloem sugar transport and cellular sugar homeostasis in rapidly growing fruits remain elusive. To elucidate the functions of hexose/H+ symporters in cucumber (Cucumis sativus L.) fruits, we conducted comprehensive analyses of their tissue-specific expression, localization, transport characteristics, and physiological functions. Our results demonstrate that CsHT3 (C. sativus hexose transporter), CsHT12, and CsHT16 are the primary hexose/H+ symporters expressed in cucumber fruits. CsHT3 and CsHT16 are localized in the sieve element-companion cell during the ovary and early fruit development stages. As the fruit develops and expands, the expression of both symporters shifts to phloem parenchyma cells. The CsHT16 knockout mutant produces shorter fruits with a larger circumference, likely due to impaired sugar and phytohormone homeostasis. Concurrent reduction of CsHT3, CsHT12, and CsHT16 expression leads to decreased fruit size. Conversely, CsHT3 overexpression results in increased fruit size and higher fruit sugar levels. These findings suggest that CsHT16 plays an important role in maintaining sugar homeostasis, which shapes the fruit, while CsHT3, CsHT12, and CsHT16 collectively regulate the supply of carbohydrates required for cucumber fruit enlargement.","PeriodicalId":20101,"journal":{"name":"Plant Physiology","volume":" ","pages":""},"PeriodicalIF":6.5,"publicationDate":"2025-02-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142829710","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}

The signal transduction process involves a sophisticated interplay between messengers, receptors, signal transducers, and downstream effectors. Over the years, an array of plant signaling proteins have been identified for their crucial roles in perceiving lipid signals. However, the mechanistic effects of lipid binding on protein functions remain largely elusive. Recent literature has presented numerous fascinating models that illustrate the significance of protein-lipid interactions in mediating signaling responses. This review focuses on the category of lipophilic signaling proteins that encompass a hydrophobic binding pocket located outside of cellular membranes and provides an update on the lessons learned from two of these structures, namely the acyl-CoA-binding and steroidogenic acute regulatory protein-related lipid transfer domains. It begins with a brief overview of the latest advances in understanding the functions of the two protein families in plant communication. The second part highlights five functional mechanisms of lipid ligands in concert with their target signaling proteins.","PeriodicalId":20101,"journal":{"name":"Plant Physiology","volume":" ","pages":""},"PeriodicalIF":6.5,"publicationDate":"2025-02-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142472427","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 study, we found that H2S delays dark-induced senescence in tomato (Solanum lycopersicum) leaves. Transcriptome and reverse transcription quantitative PCR (RT-qPCR) analyses revealed an ethylene response factor ERF.D3 is quickly induced by H2S. H2S also persulfidated ERF.D3 at amino acid residues C115 and C118. CRISPR/Cas9-mediated gene editing, and gene overexpression analyses showed that ERF.D3 negatively regulates leaf senescence and fruit ripening. Abscisic acid (ABA) levels were reduced by ERF.D3 overexpression, suggesting ERF.D3 might regulate ABA metabolism. Additionally, the ABA 8'-hydroxylase-encoding gene CYP707A2, which is required for ABA degradation, was identified as an ERF.D3 target gene through transcriptome data, RT-qPCR, dual-luciferase reporter assays, and electrophoretic mobility shift assays. ERF.D3 persulfidation enhanced its transcriptional activity toward CYP707A2. Moreover, the E3 ligase RNF217 ubiquitinated ERF.D3, which may accelerate fruit ripening during the late stage of fruit development. Overall, our study provides valuable insights into the roles of a H2S-responsive ERF.D3 and its persulfidation state in delaying leaf senescence and fruit ripening and provides a link between H2S and ABA degradation.","PeriodicalId":20101,"journal":{"name":"Plant Physiology","volume":" ","pages":""},"PeriodicalIF":6.5,"publicationDate":"2025-02-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142472428","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}
