Although the silicon transport mechanisms in monocots are well characterized, the molecular basis of silicon deposition in dicots remains elusive. Fruit bloom, an off-white substance covering the fruit surface and affecting its appearance, is crucial for the market-driven breeding and production of cucumbers (Cucumis sativus). However, the mechanisms regulating fruit bloom formation are not well understood. In this study, we aimed to elucidate the molecular mechanisms underlying silicon deposition in glandular trichomes (GTs) and GT’s role in fruit bloom formation. Using map-based cloning, we identified a single-nucleotide polymorphism in CsaV3_3G017280, encoding a homolog of the rice (Oryza sativa) silicon efflux transporter Low Silicon Rice 2 (Lsi2), causing a premature translation termination mutation linked to the non-fruit-bloom phenotype. Knocking out CsLsi2 prevented silicon deposition on the fruit surface, leading to a non-fruit-bloom phenotype. The MYB transcription factor CsRAX3 directly activated CsLsi2, and the GT development–related factor TINY BRANCHED HAIR (TBH) regulated both CsRAX3 and CsLsi2, linking silicon deposition with GT development. Collectively, our observations establish a direct connection between Si deposition and GT development and provide a perspective on the mechanisms regulating fruit bloom formation.","PeriodicalId":501012,"journal":{"name":"The Plant Cell","volume":"671 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-07-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144629840","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}

However, the genetic mechanisms governing root hair traits in wheat (Triticum aestivum L.) remain largely unexplored. In this study, we identified the awn inhibitor gene B1 as an important regulator of root hair length (RHL) through map-based cloning and reported a preferred allele for an ideotype of the root system in wheat. B1 suppressed RHL by decreasing reactive oxygen species (ROS) buildup, whereas a defective B1 resulted in increased RHL and enhanced nutrient uptake efficiency in wheat. In addition, B1 directly repressed the expression of ROOT HAIR DEFECTIVE SIX-LIKE2 (TaRSL2) and ROOT HAIR DEFECTIVE SIX-LIKE4 (TaRSL4), encoding two positive regulators of RHL, thereby activating TaRBOHH9 expression and accelerating ROS production. Furthermore, B1 interacted with TaHDA6, reducing histone H3K9ac and H3K14ac modifications and inhibiting the expression of downstream genes. Our work not only unveils the pivotal role of B1-mediated epigenetic regulation of RHL and nutrient uptake, but also presents editable molecular targets for breeding eco-friendly sustainable crops.","PeriodicalId":501012,"journal":{"name":"The Plant Cell","volume":"23 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-07-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144629841","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}

Our research delves into the molecular mechanisms that regulate tomato (Solanum lycopersicum) plant adaptation to Pi deficiency, highlighting the role of two PHOSPHATE STARVATION RESPONSE (PHR) transcription factors, SlPHR3 and SlPHR4, as central regulators of Pi metabolism and related developmental/physiological processes, particularly PSRs. Notably, our investigation into the SlPHR3- and SlPHR4-regulated transcriptional network led to the discovery of three previously unidentified regulators of Pi metabolism and PSRs: SlGRAS47, SlBHLH48, and SlMYB28. We substantiated the important roles of SlMYB28 in mediating SlPHR3 and SlPHR4 function by demonstrating that SlMYB28 suppression reduces Pi and P accumulation, ameliorates PSR-related phenotypes, and decreases the expression of genes involved in Pi metabolism and PSRs in SlPHR3 and SlPHR4 overexpression plants. Our findings shed light on the adaptive strategies of plants to Pi starvation and open avenues for the identification of important genes involved in Pi metabolism and PSRs, which can be leveraged to improve Pi use efficiency in agricultural crops.","PeriodicalId":501012,"journal":{"name":"The Plant Cell","volume":"9 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144533080","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}

Here, we identified AtFOX1, a previously uncharacterized forkhead box (FOX) protein in Arabidopsis (Arabidopsis thaliana), as a positive regulator of leaf senescence. Loss-of-function AtFOX1 mutants exhibit delayed senescence, whereas AtFOX1 overexpression accelerated this process. Mechanistically, AtFOX1 binds to the GTAAAA motif in the TGACG SEQUENCE-SPECIFIC BINDING PROTEIN 7 (TGA7) promoter, recruiting ARABIDOPSIS HISTONE ACETYLTRANSFERASE OF THE CBP FAMILY 1 (HAC1) to enhance histone H3 lysine 9 (H3K9) acetylation and promote TGA7 transcription. Genetic analyses demonstrated that AtFOX1-mediated senescence requires HAC1 function, while TGA7 acts downstream of HAC1. Furthermore, TGA7 directly activates ABA-RESPONSIVE ELEMENT BINDING FACTOR 2 (ABF2) and ABF3, key regulators of age- and ABA-induced leaf senescence. Disruption of ABF2/3/4 function mitigated the premature senescence phenotype resulting from TGA7 or AtFOX1 overexpression.

Here, we show that a large cluster of tomato (Solanum lycopersicum) genes, encoding the cyst and root-knot nematode disease resistance proteins Hero and MeR1 as well as the NLR helper NLR required for cell death 6 (NRC6), is nearly exclusively expressed in the roots. This root-specific gene cluster emerged in Solanum species about 21 million years ago through gene duplication of the ancient asterid NRC network. NLR sensors in this gene cluster function exclusively through NRC6 helpers to trigger hypersensitive cell death. These findings indicate that the NRC6 gene cluster has sub-functionalized from the larger NRC network to specialize in mediating resistance against root pathogens, including cyst and root-knot nematodes. We propose that some NLR gene clusters and networks may have evolved organ-specific gene expression as an adaptation to particular parasites and to reduce the risk of autoimmunity.","PeriodicalId":501012,"journal":{"name":"The Plant Cell","volume":"27 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144513136","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}

We asked experts how discoveries in Arabidopsis thaliana have translated into advancements in abiotic crop stress resilience. The theme is that core regulatory networks identified in Arabidopsis are conserved in crops, but the molecular regulation varies among species. For cold tolerance, the regulatory framework is conserved, but MAP Kinase signaling promotes degradation of the INDUCER OF DREB1 EXPRESSION (ICE) transcription factor in Arabidopsis but inhibits it in rice. For hypoxia, manipulation of the oxygen sensing Arg/N-degron pathway discovered in Arabidopsis has improved waterlogging and flood tolerance in barley, maize, wheat, and soybean. For light signaling, overexpression of PHYTOCHROME B reduces shade avoidance, improving yield under dense planting in potato, soybean, and maize. In rice, understanding of nitrogen responsiveness, uptake, and transport in Arabidopsis has inspired engineering of the NRT1 nitrate transceptor to increase yield. Overexpressing Arabidopsis genes in crops confers drought tolerance, although none have been commercialized. Growing plants in space generates a complex array of stresses, and Arabidopsis experiments in the space station prepare for future development of robust crops as integral components of the life support systems. For environmental regulation of flowering time, the role of the GIGANTEA (GI) - CONTANS (CO) - FLOWERING LOCUS T (FT) module elucidated in Arabidopsis is largely conserved in crop plants, although additional regulators modify short day responsiveness in rice, soybean, chrysanthemum, and potato.","PeriodicalId":501012,"journal":{"name":"The Plant Cell","volume":"22 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144503734","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}
