However, their roles and molecular mechanisms in coordinating plant immunity and growth remain poorly characterized. Here, we report a rice-specific miRNA, osa-miR2871a-3p (miR2871), negatively regulates rice resistance to Xanthomonas oryzae pv oryzae (Xoo) by modulating cell wall biosynthesis. We demonstrated that the transcription factor OsWRKY72 directly binds to the OsMIR2871 promoter and activates its expression. miR2871 suppresses cell wall biosynthesis by directly targeting OsGT43G, which encodes an endoplasmic reticulum-localized glycosyltransferase protein. Genetic and physiological analysis revealed that both miR2871-downregulating (STTM2871) and OsGT43G-overexpressing (GT43G-ox) plants exhibit enhanced resistance to Xoo by maintaining a high level of cellulose and lignin content. Furthermore, we suggested that OsGT43G stabilizes OsMYB63 through physical interactions, co-activating OsCesA4/7/9 expression to confer rice resistance to Xoo. Finally, phenotypic assays showed that STTM2871, GT43G-ox, and OsWRKY72 knockout (wrky72-ko) lines confer broad-spectrum resistance to Xoo without yield penalty. Collectively, our findings uncover a rice-specific miRNA and provide novel insights into the role of the OsWRKY72-miR2871-OsGT43G module in mediating rice's response to Xoo, which offers a new strategy to improve rice resistance to bacterial pathogens.","PeriodicalId":214,"journal":{"name":"New Phytologist","volume":"28 1","pages":""},"PeriodicalIF":9.4,"publicationDate":"2025-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145068335","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}

PhyA and phyB, representing distinct evolutionary lineages, utilize different nuclear import mechanisms. PhyA, specialized for far-red light sensing, relies on FAR-RED ELONGATED HYPOCOTYL1 (FHY1) and FHY1-LIKE for nuclear entry, whereas phyB employs light-induced unmasking of its nuclear localization signals. Calcium signaling plays a critical role in phyB phototransduction, with calcium-dependent protein kinases CPK6/12 phosphorylating phyB at Ser80/Ser106 to initiate its nuclear import. Once in the nucleus, phytochromes localize to photobodies - membraneless condensates formed through liquid-liquid phase separation - which serve as hubs integrating light and temperature signals to regulate transcription and protein turnover. Evolutionary studies indicate that FHY1-mediated import mechanisms predate the divergence of land plants, while the phyB-like import mechanisms developed later in seed plants. Early diverged land plants, such as liverworts and mosses, retain ancestral phytochromes with dual red/far-red light responsiveness, likely employing hybrid nuclear import strategies. Gene duplication has driven the functional diversification of phytochromes, enabling adaptive specialization to complex light environments. This review synthesizes molecular and evolutionary perspectives on phytochrome nuclear import, highlighting calcium-dependent phosphorylation as a key regulatory mechanism and emphasizing the conserved yet adaptable nature of light signaling.","PeriodicalId":214,"journal":{"name":"New Phytologist","volume":"21 1","pages":""},"PeriodicalIF":9.4,"publicationDate":"2025-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145035690","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 mechanism of P3IP-mediated autophagy and the evolutionary conservation of its antiviral function remain unknown. This study demonstrates that two Arabidopsis thaliana homologs, AtP3IP and AtP3IPH (Arabidopsis P3IP homologs, AtP3IPs), similarly activate autophagy and confer resistance to turnip mosaic virus (TuMV). We show that AtP3IPs activate autophagy by competitively disrupting the interaction between glyceraldehyde-3-phosphate dehydrogenases (GAPCs), known negative regulators of autophagy, and the autophagy-related protein ATG3. This represents the first identification of an endogenous host factor that modulates autophagy through targeting the GAPC-ATG3 regulatory axis. Functional analyses revealed that AtP3IP-overexpressing plants exhibit enhanced TuMV resistance, whereas loss-of-function mutants are more susceptible. Notably, AtP3IPs directly interacted with TuMV 6K2 protein and facilitated its autophagic degradation. Collectively, our findings demonstrate the conserved role of P3IPs in autophagy activation and reveal a novel mechanism through which P3IPs stimulate autophagy by disrupting the inhibitory GAPC-ATG3 regulatory module. Additionally, TuMV 6K2 is identified as a new target of host autophagy. These expand our understanding of plant antiviral defenses and provide potential targets for engineering broad-spectrum resistance against viral pathogens.","PeriodicalId":214,"journal":{"name":"New Phytologist","volume":"32 1","pages":""},"PeriodicalIF":9.4,"publicationDate":"2025-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145025492","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}

Nitrate ammonification has been studied in enrichment and axenic bacterial cultures but so far has been merely ignored in environmental studies. In particular, the capability of arbuscular mycorrhizal fungi (AMF) to regulate nitrate ammonification has not yet been explored. Here, nitrate ion (15NO3 -) was used to trace N transformations in hyphosphere and bulk soils. Metagenomic analysis was conducted, and cross-kingdom interactions between AMF and an isolated nirBD-carrying Paenibacillus sp. strain DP01 from hyphosphere soil were investigated. AMF hyphae significantly increased ammonium ion (NH4 +) concentration and 15NH4 + derived from 15NO3 - in hyphosphere soil, which were 1.42 and 5.01 times as high as those in bulk soil. Metagenomic analysis showed that the nirB gene involved in nitrite reduction to ammonium was prevalent in hyphosphere and bulk soils. Hyphal exudates enhanced ammonification efficiency and biofilm formation of the nitrite-ammonifying strain DP01. Additionally, accelerated oxygen depletion was detected on hyphal surface. This study demonstrates a novel interaction in which AMF significantly enhanced nitrate ammonification in the hyphosphere. Given the widespread presence of nitrate-ammonifying microbes in soils, this newly described interkingdom interaction offers guidance for agricultural practices aimed at increasing N efficiency and environmental sustainability.","PeriodicalId":214,"journal":{"name":"New Phytologist","volume":"5 1","pages":""},"PeriodicalIF":9.4,"publicationDate":"2025-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145025493","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}
