However, their potential roles in inhibiting adventitious root (AR) and lateral root (LR) formation in trees remain unclear. Here, we report that the ABA-responsive C2H2-type zinc finger protein transcription factor (PuZFP1) regulates Populus ussuriensis root development to enhance drought tolerance. PuZFP1 negatively regulates LR development by binding to the PuWRKY46 promoter and inhibiting its expression. At the same time, PuZFP1 promotes AR elongation by repressing Clade E Growth-Regulating (EGR) Type 2C protein phosphatases (PuEGR1). In PuZFP1-overexpressing lines, a higher ABA/IAA ratio in the differentiation zone (DZ) drives PuWRKY46-mediated LR inhibition. Conversely, a lower ABA/IAA ratio is associated with AR elongation and the expression of the downstream target gene PuEGR1 in the elongation zone (EZ). Notably, PuZFP1 physically interacts with Ubiquitin-like protein 5 (PuUBL5) and undergoes 26S proteasome-mediated degradation. Taken together, our findings shed light on the role of the PuUBL5-PuZFP1 module in mediating the crosstalk between LR emergence and AR elongation via ABA/auxin signaling in drought-stressed P. ussuriensis, and provide insights into the regulatory network underlying PuZFP1-mediated root growth in poplar.","PeriodicalId":20101,"journal":{"name":"Plant Physiology","volume":"13 1","pages":""},"PeriodicalIF":7.4,"publicationDate":"2025-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143945543","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 by which photoperiod and seasonal changes influence the physiological response of day-neutral plants, such as tomato (Solanum lycopersicum), remains unclear. Here, we found that the tomato CONSTANS (CO) close homolog, CONSTANS-Like1 (SlCOL1), does not affect the flowering of tomato under either long-day (LD) or short-day (SD) conditions. However, CRISPR/Cas9-mediated editing of SlCOL1 showed a much lower anthocyanin accumulation in mutant than in wild-type plants, especially under SD at suboptimal low-temperature conditions. SlCOL1 directly activated the Hoffman's Anthocyanin 1 (SlAN1) promoter and interacted with SlAN1 to promote anthocyanin biosynthesis under SD. The cold-induced up-regulation of SlCOL1 further promoted anthocyanin accumulation and enhanced Reactive oxygen species (ROS) scavenging under SD at low-temperature conditions. These results reveal that the SlCOL1-SlAN1 module collaboratively regulates anthocyanin accumulation under SD and cold conditions, which could help tomato counteract the cold autumn/winter season in nature.","PeriodicalId":20101,"journal":{"name":"Plant Physiology","volume":"164 1","pages":""},"PeriodicalIF":7.4,"publicationDate":"2025-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143945548","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 N6-methyladenosine (m6A) RNA modification is fundamental to plant growth and development. However, the molecular mechanisms underlying the regulation of PHYTOCHROME B (phyB) and the function of m6A signaling in GA-mediated seed germination remain elusive. Here, we discovered EVOLUTIONARILY CONSERVED C-TERMINAL REGION 1 (ECT1) as an m6A reader protein that directly binds to m6A and forms homodimers to enhance its stability in Arabidopsis (Arabidopsis thaliana). We observed that the ect1-1 mutant exhibits attenuated GA3 responsiveness in seed germination. Restoration of ECT1 function in ect1-1 confirmed the role of ECT1 in promoting seed germination. Our findings indicate that ECT1 promotes seed germination by destabilizing m6A-modified REPRESSOR OF GA1-3 1 (RGA1), a key inhibitor of GA-mediated seed germination. Moreover, ECT1 establishes a regulatory circuit with DOF AFFECTING GERMINATION 2 (DAG2), another regulator of GA-mediated seed germination. DAG2 directly binds to the ECT1 promoter and controls its transcription, and ECT1 modulates DAG2 mRNA stability through m6A binding. Furthermore, we identified PHYB as a common downstream target of DAG2 and ECT1. ECT1 binds directly to m6A-modified PHYB and influences its stability, and DAG2 binds to the PHYB promoter to regulate its transcription. Our findings demonstrate that ECT1 fine-tunes m6A-regulated seed germination via complex and multifaceted molecular mechanisms, particularly through interactions with GA and phyB, broadening our understanding of m6A-regulated processes in Arabidopsis.","PeriodicalId":20101,"journal":{"name":"Plant Physiology","volume":"25 1","pages":""},"PeriodicalIF":7.4,"publicationDate":"2025-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143932713","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 roles of Major Facilitator Superfamily (MFS) transporters in sugar metabolism and regulation remain largely unexplored. This study employed a combination of spatial metabolomics, quantitative genetics, transcriptomics, comparative genomics, and functional genomics to investigate the role of 67 MFS members in balancing sugar metabolism during peach fruit development. Spatial metabolomics revealed dynamic sugar distribution patterns, with ERD6-like transporters (PpERDL16-1) and tonoplastic sugar transporters 1 (PpTST1) promoting sucrose accumulation and Polyol/monosaccharide transporters 5 (PpPMT5-1) and sucrose transporters 4 (PpSUT4) reducing sucrose transport during fruit ripening. Functional studies confirmed these roles: PpERDL16-1 overexpression enhanced sucrose transport, and PpPMT5-1 or PpSUT4 silencing reduced sugar levels in peach fruit. Quantitative trait locus (QTL) mapping identified a major locus on chromosome 5, upstream of PpTST1, forming distinct haplotypes (Hap1 and Hap2). Hap1 was associated with lower PpTST1 expression and higher sugar and soluble solids content (SSC), while Hap2 was linked to higher PpTST1 expression and lower sugar content. This inverse relationship suggests that upstream genetic variants fine-tune PpTST1 expression in a context-dependent manner, potentially through interactions with transcription factors or epigenetic modifiers. Notably, PpTST1 overexpression increased sugar content but did not alter SSC, indicating compensatory mechanisms such as changes in organic acid metabolism or water content. These results illuminate the molecular mechanisms regulating sugar homeostasis in peach fruits, providing valuable targets for the genetic improvement of fruit quality through breeding programs.","PeriodicalId":20101,"journal":{"name":"Plant Physiology","volume":"32 1","pages":""},"PeriodicalIF":7.4,"publicationDate":"2025-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143932716","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}

Mutants of the Arabidopsis (Arabidopsis thaliana) ATP-Binding Cassette G 43 (ABCG43) transporter gene show enhanced root-substrate cohesion, even though their root micro- and macro-structures are similar to those of wild-type Arabidopsis. We used genetic, biochemical, and functional methods to characterise the substrate-binding effects of changes in ABCG43 expression, including differences in exudate composition, and phylogenetic analyses to explore the evolutionary history of ABCG43 in land plants. Exudates from roots of the abcg43 mutant bound more soil and growing medium, and there were significant differences in abcg43 root exudate composition compared with the wild type. These results suggest that ABCG43 normally functions to mediate root exudates that affect root-substrate cohesion. Phylogenetic analysis showed that ABCG43 is highly conserved in plants, including in agriculturally important crop species. These results provide evidence that ABCG43 is a promising molecular target for developing crop plants with enhanced root-soil cohesion.","PeriodicalId":20101,"journal":{"name":"Plant Physiology","volume":"37 1","pages":""},"PeriodicalIF":7.4,"publicationDate":"2025-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143932717","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}

Genetic analysis of the glabrous stem landrace (Palmeri37) of Gossypium hirsutum L. has pinpointed GL2-interacting-repressor 1 (GhGIR1D), featuring a RING-like zinc finger domain, as the candidate gene underlying the stem glabrous trait. Overexpressing and silencing experiments confirm GhGIR1D as a negative regulator specifically for stem trichome initiation, without influencing leaf trichome or seed fiber. High endogenous expression of GhGIR1D is associated with a SNP-573 T/G variation within the promoter region, and GhGIR1D Hap I confers the absence of stem trichomes. The homoeologous protein, GhGIR1A, inhibits trichome and fuzz fiber initiation by disrupting the GhHD1D-GhHOX3A module (a complex of two Homeodomain-Leucine Zipper IV transcription factors, HD-ZIP IV), and repressing downstream transcription of GhRDL1. Trichome density was enhanced in GhHD1A overexpression transgenic lines but reduced in ghhd1a mutants, demonstrating the positive regulatory role of GhHD1A on stem trichome initiation. GhHD1 displays distinct effects on stem trichome and fuzz fiber initiation due to its tissue-specific dosage. In the ghhd1a mutants, repression of GhGIR1D restores the wild-type pubescent phenotype, suggesting the presence of a potential negative feedback loop between GhGIR1D and GhHD1A, or that GhGIR1D and GhHD1A may function within the same regulatory pathway with opposite functions in regulation of trichome development. These findings enhance our comprehension of the GhGIR1-GhHD1-GhHOX3 interaction module in epidermal hair initiation and development.","PeriodicalId":20101,"journal":{"name":"Plant Physiology","volume":"21 1","pages":""},"PeriodicalIF":7.4,"publicationDate":"2025-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143932714","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 tracked the rate of residual water loss, the compositional development of cuticular wax, stomatal differentiation, pore formation, and xylem development as leaves expand in two co-occurring, deciduous tree species Tilia americana and Fagus grandifolia. As leaves expanded, residual conductance declined rapidly, primarily driven by decreases in cuticular conductance, which was the main pathway for residual water loss from branches with young leaves. Very little water was lost through stomatal pores as leaves expanded, because the outer cuticular ledge only formed above the majority of stomata once leaves approached complete expansion. Similar development of residual conductance was observed between the two species despite differences in cuticle composition and stomatal development timing as leaves expanded. Our work suggests that the cuticle is the primary pathway through which water is lost from the youngest expanding leaves, and residual conductance is minimized only when cuticular wax deposition is complete, stomata have formed, and leaves have fully expanded.","PeriodicalId":20101,"journal":{"name":"Plant Physiology","volume":"58 1","pages":""},"PeriodicalIF":7.4,"publicationDate":"2025-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143930850","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}

It is polarly localized at the distal side of the root exodermis and endodermis. Although OsLsi1 is also permeable to other metalloids, such as boron (B), germanium (Ge), arsenic (As), antimony (Sb), and selenium (Se), the role of its polar localization in the uptake of these metalloids remains unclear. In this study, we investigated the role of OsLsi1 polar localization in metalloid uptake by examining transgenic rice plants expressing polarly or non-polarly localized OsLsi1 variants. Loss of OsLsi1 polar localization resulted in decreased accumulation of Ge, B, and As in shoots but increased Sb accumulation, while Se accumulation remained unaffected under normal conditions. Experiments with varying B concentrations revealed that B uptake is significantly lower at low B concentrations (0.3–3 μM) but higher at high B concentrations (300 μM) in plants expressing non-polarly localized OsLsi1, despite the similar B permeability of both OsLsi1 variants in Xenopus oocytes and their comparable protein abundance in roots. Additionally, the loss of OsLsi1 polarity did not affect the abundance, localization, or high B-induced degradation of the borate transporter 1 (OsBOR1), an efflux transporter that cooperates with OsLsi1 for B uptake. Taken together, our findings demonstrate that the polar localization of OsLsi1 plays a critical role in regulating metalloid uptake, depending on the presence or absence of efflux transporters cooperating with OsLsi1.","PeriodicalId":20101,"journal":{"name":"Plant Physiology","volume":"38 1","pages":""},"PeriodicalIF":7.4,"publicationDate":"2025-05-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143927312","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}
