Salix matsudana, a willow species, demonstrates exceptional tolerance to hypoxia and submergence stress, providing an ideal model for exploring underlying molecular mechanisms. This study highlights the roles of two transcriptional factors and their interplay in enhancing hypoxia and submergence stress resilience in Salix matsudana. SmTTF30, a GT-1 trihelix transcription factor, is specifically induced under root hypoxia, with its promoter enriched in hypoxia-responsive elements. Functional analyses reveal that overexpression of SmTTF30 in Arabidopsis thaliana improves submergence tolerance, whereas its downregulation in Salix matsudana results in heightened submergence stress sensitivity. SmDREB A1-10, identified through yeast one-hybrid screening and dual-luciferase assays as an upstream regulator of SmTTF30, directly interacts with its promoter. Overexpression of SmDREB A1-10 in Arabidopsis thaliana also enhances submergence tolerance, similar to SmTTF30. Virus-induced gene silencing (VIGS) experiments confirm that silencing SmDREB A1-10 diminishes SmTTF30 expression and hypoxia-responsive gene activation, exacerbating submergence stress effects. These findings unveil a regulatory cascade involving SmDREB A1-10 and SmTTF30 in submergence stress responses, providing insights into transcriptional networks governing submergence tolerance in trees.","PeriodicalId":222,"journal":{"name":"Plant, Cell & Environment","volume":" ","pages":""},"PeriodicalIF":6.0,"publicationDate":"2025-02-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143481873","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 mediator subunit, such as MED25, plays a crucial role in regulating plant growth and development. This study elucidated the mechanistic role of OsMED25, an integral subunit of the plant mediator transcriptional coactivator complex, in the regulation of plant height. Phenotypic results indicated a significant reduction in plant height in the OsMED25-RNAi line. Further analysis indicated that GA1 and GA3 levels were significantly reduced, and the expression of gibberellin biosynthesis-related genes OsGA20ox1, OsGA20ox2 and OsGA20ox8 was significantly downregulated. Additionally, multiple lines of evidence supported an interaction between OsMED25 and OsWRKY78. The oswrky78 mutants exhibited significantly reduced plant height, and molecular analysis demonstrated that OsWRKY78 directly binds to the promoter region of OsGA20ox1 to activate its expression. Intriguingly, we demonstrated that OsMED25 acted as a coactivator for OsWRKY78, enhancing the transcription of OsGA20ox1. This led to elevated GA levels, positively regulating plant height. In summary, these findings demonstrated that OsMED25 played a pivotal role in regulating plant height by modulating the expression of OsGA20ox1, thereby providing a potential strategy for genetic improvement in rice.","PeriodicalId":222,"journal":{"name":"Plant, Cell & Environment","volume":" ","pages":""},"PeriodicalIF":6.0,"publicationDate":"2025-02-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143490079","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 a dodder-connected plant cluster, salt-induced systemic priming signals are transferred from the salt-stressed host (signal donor, SD) to the other host (signal receiver, SR) through dodder and prime the SR plants for enhanced salt tolerance, but what signalling pathways regulate the dodder-mediated interplant priming signals remain unclear. In this study, using genetic analyses, we show that in dodder-connected tobacco (Nicotiana tabacum) clusters, the strigolactone (SL), reactive oxygen species (ROS) and abscisic acid (ABA) pathway in the SD plants negatively control the salt stress-induced systemic signals from SD to SR plants. Transcriptome data suggested that the salt-induced systemic signals regulated by SLs in the SD plants may also affect the ABA and ROS signalling pathway in the SR plants. Quantification of the ABA and H2O2 contents in the SD plants suggested that the SL and ROS signalling likely converge on the ABA pathway to regulate the priming signals. This study reveals the important regulatory roles of phytohormones and ROS in dodder-mediated interplant communications and provides new insight into systemic signalling during salt stress adaptation in individual plants.","PeriodicalId":222,"journal":{"name":"Plant, Cell & Environment","volume":" ","pages":""},"PeriodicalIF":6.0,"publicationDate":"2025-02-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143466418","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 demonstrate that transcription of VvprePIP from grape (Vitis vinifera) encoding the precursor of a PIP (PAMP-Induced secreted Peptide) peptide is activated by Plasmopara viticola infection. Overexpression of VvprePIP increases the expression of defence-related genes and ROS (Reactive Oxygen Species) production, enhancing resistance to P. viticola in V. vinifera. A WRKY transcription factor VvWRKY8 interacts with VvprePIP promoter, upregulating its transcription directly. The immune reactions resulting from ectopic expression of VvprePIP are impaired in NbBAK1-silencing tobacco, implying BAK1 is necessary for the recognition between mature peptide VvPIP and its receptor. The conserved region at the C terminus of VvprePIP carries three typical SGPS-GH motifs, all of which contribute to provoke immune responses in plant. As synthetic VvPIP with a hydroxylated modification at the forth proline can mimic the functions of overexpression of the precursor, while synthetic unmodified VvPIP cannot, we reported that hydroxyproline is required for VvPIPs to serve as an active signal molecular. In conclusion, our studies reveal that VvprePIP plays a role in enhancing plant resistance to pathogens.","PeriodicalId":222,"journal":{"name":"Plant, Cell & Environment","volume":" ","pages":""},"PeriodicalIF":6.0,"publicationDate":"2025-02-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143466482","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 identified and characterised the homologue of yeast NUC1p, termed PstNUC1, in Puccinia striiformis f. sp. tritici (Pst), the causal agent of wheat stripe rust. PstNUC1 was induced during infection and was secreted to the extracellular space of the host. Silencing of PstNUC1 significantly attenuated the virulence of Pst, suggesting its critical role in pathogenicity. Exogenous treatment of PstNUC1 diminished the extracellular DNA (exDNA)-triggered plant immune response, including cell death, oxygen peroxide production, and upregulation of Pathogenesis-related genes. Notably, overexpression of wild-type PstNUC1, but not a signal peptide-deficient mutant (PstNUC1ΔSP), in wheat compromised exDNA-triggered immunity, resulting in enhanced susceptibility to Pst infection. These finding collectively highlight the contribution of PstNUC1 to virulence through degradation of exDNA, thereby dampening the exDNA-induced plant immune response.","PeriodicalId":222,"journal":{"name":"Plant, Cell & Environment","volume":" ","pages":""},"PeriodicalIF":6.0,"publicationDate":"2025-02-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143466415","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}

Exogenous salicylic acid (SA) has emerged as an effective strategy to mitigate leaf senescence and HT-induced damage, though its underlying mechanisms remain unclear. This study investigated the regulatory mechanism of SA application on waxy maize subjected to HT during the early filling stage. Compared to HT alone, exogenous SA alleviated the inhibition of photosynthesis and oxidative damage by enhancing the activities of enzymes involved in photosynthesis and antioxidant system and modulating phytohormone metabolism and signal transduction pathways, thereby reducing leaf senescence and mitigating yield loss under HT. Transcriptomic and metabolomic analyses showed that HT downregulated most genes involved in the starch and sucrose metabolism pathway in leaves but promoted soluble sugar accumulation, which represents a plant strategy to cope with HT. Conversely, exogenous SA reversed this change and further enhanced soluble sugar accumulation in leaves. SA also regulated sugar metabolism by inhibiting trehalose-6-phosphate synthesis and activating SnRK1 to resist HT. Furthermore, SA stimulated lignin biosynthesis through the phenylpropanoid pathway, ensuring cell membrane integrity under HT. The relationship between SA signalling and plant heat tolerance was validated using a maize SA synthesis-synthetic mutant.","PeriodicalId":222,"journal":{"name":"Plant, Cell & Environment","volume":" ","pages":""},"PeriodicalIF":6.0,"publicationDate":"2025-02-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143447478","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}

This study identified LNC159c as a potential regulator of anthocyanin biosynthesis, with its expression notably downregulated under LN conditions. LNC159c functions as the host gene of miR159c, which regulates its expression. A dual-luciferase reporter assay and GFP signal detection demonstrated that miR159c inhibited MsMYB10 expression through base complementary pairing. Yeast one-hybrid (Y1H) and dual-LUC reporter assays jointly verified that MsMYB10 binds to the F3'H promoter. Stable overexpression in apple calli and transient overexpression in apple fruit peels and M. spectabilis leaves showed that LNC159c overexpression promoted miR159c expression, while inhibiting MsMYB10 expression and anthocyanin biosynthesis. MsMYB10 overexpression promoted anthocyanin biosynthesis, whereas the opposite results were observed in MsMYB10-silenced tissues. Thus, under LN conditions, reduced LNC159c expression limits miR159c production, relieving MsMYB10 inhibition and enhancing anthocyanin accumulation.

However, in the presence of nitrogen, this process is rapidly repressed to avoid unnecessary investments of carbon in the symbiosis. Several players involved in regulating nodulation in response to nitrate availability have been identified, including peptide hormones, microRNAs and transcription factors. Nevertheless, how these molecular players are linked to each other and what underlying molecular mechanisms are at play to inhibit nodulation remain unresolved. Nitrate-mediated control of nodulation seems to differ between model legumes, such as Medicago and Lotus, compared to legume crops such as soybean. A deeper understanding of these regulatory processes, particularly in soybean, is expected to contribute to establishing increased nodulation efficiency in modern agricultural systems, hence improving sustainability by reducing the need for environmentally hazardous nitrogen fertilizers. This review describes the state of the art of nitrate-regulated nodulation in soybean, while drawing parallels with molecular mechanisms described in other legumes and addressing knowledge gaps that require future study.","PeriodicalId":222,"journal":{"name":"Plant, Cell & Environment","volume":" ","pages":""},"PeriodicalIF":6.0,"publicationDate":"2025-02-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143439454","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}

Plant adaption to low mineral environments involves signaling between shoots and roots, via the food transport cells, the sieve elements. However, due to the sequestered position of the sieve elements in the vascular bundles, identifying shoot-to-root mobile signals is challenging. In herbaceous species, sieve elements and companion cells (CCs) are isolated from other leaf tissues. We hypothesize that phloem CCs play an essential role by synthesizing shoot-to-root signals in response to mineral deficiency. To test this hypothesis, we analyzed gene expression responses in Arabidopsis CCs under phosphorus deficiency using TRAP-Seq. Phosphorus was chosen for its importance in plant growth and the known role of shoot-to-root signaling in regulating root phosphate transporters during deficiency. Our findings revealed that CCs exhibit more dramatic molecular responses than other leaf cells. We also found that many genes altered in CCs have potential functions in regulating root growth. This is unexpected because it has been widely believed that shoot-to-root signaling is not involved in root growth regulation under P deficiency. The importance of CCs in regulating mineral deficiency may extend beyond phosphorus because shoot-to-root signaling is a common response to the deficiency of various minerals.","PeriodicalId":222,"journal":{"name":"Plant, Cell & Environment","volume":" ","pages":""},"PeriodicalIF":6.0,"publicationDate":"2025-02-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143439458","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}
