However, the molecular mechanisms underlying this process remain elusive. Here, we uncovered the roles of miR397a in GA signalling-mediated grape seed-stone development through VvSLR1-VvWRKY26 cascade modulation in grapes, indicating 'VvSLR1-VvWRKY26-VvmiR397a-VvLAC4' is the key signalling regulatory module in lignin synthesis of seed-stone in GA-induced grape parthenocarpic berries. VvSLR1 inhibits VvmiR397a expression through interaction with VvWRKY26 and promotes the laccase-mediated lignin synthesis, while GA depresses lignin synthesis by overcoming VvSLR1-mediated multi-level cascade signals. We identified GA responsive cis-element of VvMIR397a promoter bound by VvWRKY26, which activated VvmiR397a expression, whereby inhibiting VvLAC4 level. The expression patterns and cleavage roles' variation of VvmiR397a-VvLAC4 during the seed stones of grape stone-hardening stage indicated that this pair is the one main regulatory module from VvLACs family in this process.

Arginine methylation is crucial for plant growth and environmental adaptation. However, its role in regulating plant responses to high temperatures remains unclear. In this study, we identified an important Type II arginine methyltransferase, PRMT5, in tea plants and confirmed its methyltransferase activity both in vivo and in vitro. Our findings revealed that CsPRMT5-mediated symmetric dimethylation of histone H4R3 (H4R3sme2) was markedly reduced under high-temperature conditions in tea plants. Both the inhibitor and gene-silencing approaches led to decreased levels of H4R3sme2 modification, resulting in alterations in theanine and catechins. We employed a genome-wide approach to analyze the RNA sequencing (RNA-seq) of tea plants subjected to ambient high temperatures, PRMT5 inhibitors, and PRMT5 silencing, along with H4R3sme2 and CsPRMT5 chromatin immunoprecipitation sequencing (ChIP-seq). Comparative analysis of these datasets indicated that genes regulated by H4R3sme2 were predominantly enriched within the reactive oxygen species (ROS), calcium ion, and hormone signalling pathways under elevated temperature conditions. Furthermore, we validated CsCDPK9 as a target gene regulated by H4R3sme2 and found that silencing CsCDPK9 resulted in increased theanine content and decreased catechin content at high temperatures. Our findings suggest that CsPRMT5-mediated H4R3sme2 plays a pivotal role in the growth of tea plants, as well as in their adaptability to fluctuations in ambient temperatures. This study provides new insights into breeding strategies aimed at developing crops that are better equipped to withstand environmental changes induced by climate change.","PeriodicalId":222,"journal":{"name":"Plant, Cell & Environment","volume":" ","pages":""},"PeriodicalIF":6.0,"publicationDate":"2025-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143954542","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}

Though light quality is an important factor for plant photomorphogenesis, its impact on the efficiency of transient expression remains unexplored. In this study, we examined the influence of five representative light qualities with varying wavelength mix on the N. benthamiana growth and recombinant green fluorescent protein (GFP) production. Plants with red and far-red light treatment (LED-red) showed the highest GFP expression, 57.4% higher than white light. Further study showed that a higher dosage of post-infiltration Agrobacterium and the resulting increase in the number of transcripts contribute to the expression rate enhancement. Moreover, as for exogenous metabolites, a 76.5% increase of accumulated taxadiene was also observed in LED-red group. Integrated transcriptomic, proteomic and metabolomic revealed that LED-red plants reduced the resistance pathways before infiltration, inducing a higher dosage of post-agroinfiltration Agrobacterium. Our results suggest that N. benthamiana grown under LED-red creates a more favorable environment for Agrobacterium growth, enhancing heterologous protein and metabolite production.

This study explored the role of ABA-priming in enhancing drought acclimation in sweet sorghum (Sorghum bicolor Moench) using physiological assessments and comparative transcriptomics. Under drought stress, ABA-primed seedlings exhibited increased plant height, larger leaves, and higher leaf water content compared to non-primed plants. While drought negatively affected photosynthesis through the regulation of photosystem I and II, ABA-priming improved photosynthesis and WUE by involving in differential expression of photosystem II genes. ABA-priming promoted the accumulation of cuticular wax and cutin, effectively reducing leaf water loss. Drought triggered endogenous ABA production via ABA inactivation genes (UGT, BGLU), while ABA-priming activated auxin (IAA) biosynthesis via YUCCA, enhancing auxin-mediated responses and gibberellic acid (GA) signalling. The synergistic action of ABA and IAA culminated in enhanced drought tolerance. Additionally, ABA-priming and drought stress regulated NAC transcription factors, with SbNAC21-1 emerging as a pivotal transcriptional activator intricately linked to auxin signalling. Overexpression of SbNAC21-1 in Arabidopsis effectively enhanced drought tolerance. These findings offer valuable insights into the intricate mechanisms underpinning the beneficial effects of ABA-priming, ultimately enhancing plant adaptability to environmental stressors.","PeriodicalId":222,"journal":{"name":"Plant, Cell & Environment","volume":" ","pages":""},"PeriodicalIF":6.0,"publicationDate":"2025-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143951381","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}

MicroRNAs (miRNAs), a class of short noncoding RNAs, function as master regulators of gene expression by targeting mRNAs for cleavage or direct translational inhibition at the posttranscriptional level in eukaryotes. Numerous miRNA molecules that control significant agronomic properties in plants have been found. On the one hand, miRNAs target transcription factors (TFs) to determine plant structure, such as root development, internode elongation, leaf morphogenesis, sex determination and nutrient transition. On the other hand, miRNAs alter expression levels to adapt to biological and abiotic stresses, including fungi, bacteria, viruses, drought, waterlogging, high temperature, low temperature, salinity, nutrient deficiencies, heavy metals and other abiotic stresses. To fully understand the role of miRNAs in plants, we review the regulatory role of miRNAs in plant development and stress resistance. Beyond that, we propose that the novel miRNA in review can be effectively further studied with artificial miRNA (amiRNA) or short tandem target mimics (STTM) and miRNA delivery in vitro can be used to improve crop yield and agricultural sustainability.","PeriodicalId":222,"journal":{"name":"Plant, Cell & Environment","volume":" ","pages":""},"PeriodicalIF":6.0,"publicationDate":"2025-04-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143957809","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}

Confocal observation demonstrated that cells in the RE stage have a higher mitochondrial density and increased mitochondrial motility compared to other stages. Proteomic analysis of isolated mitochondria revealed an upregulation of the tricarboxylic acid cycle, along with a synchronous increase in both mitochondrial- and nuclear-encoded components of oxidative phosphorylation in RE cells. Moreover, the upregulation of various mitochondrial membrane transporters in RE cells suggests an enhanced exchange of metabolic intermediates and inorganic ions with the cytosol. Intriguingly, ultrastructural analysis and pharmacological treatments revealed membrane interactions between the endoplasmic reticulum (ER) and mitochondria in RE cells.

Recent research has uncovered the morphological, physiological, and molecular mechanisms underlying water stress adaptation in model plants. This review synthesizes recent advances in understanding water adaptation, not only in model terrestrial plants but also in amphibious and aquatic plants. Plants respond to flooding stress through various adaptive strategies, including (1) the low-oxygen quiescence strategy (LOQS), which conserves energy by pausing metabolism and growth during flooding, and (2) the low-oxygen escape strategy (LOES), where plants elongate organs rapidly to reach the water surface and access more oxygen. In amphibious plants, heterophylly enables the production of dramatically different leaf forms to adapt to terrestrial versus submerged environments, representing a third strategy- the \"variation\" strategy for water stress adaptation. Unlike terrestrial crops, which must \"wait\" or \"escape\" during flooding, amphibious plants can naturally thrive in both aquatic and terrestrial habitats. In addition to heterophylly, other mechanisms of water stress adaptation in amphibious and aquatic plants are also discussed. Understanding these mechanisms can advance our knowledge for developing future flood-resilient crops, which are essential for sustainable agriculture under changing climates.","PeriodicalId":222,"journal":{"name":"Plant, Cell & Environment","volume":" ","pages":""},"PeriodicalIF":6.0,"publicationDate":"2025-04-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143959493","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}
