However, the regulatory mechanism governing epidermal hair formation in rice remains unclear. Here, we report that OsSCR1 (SCARECROW1) and OsSCR2 redundantly promote development of three types of rice trichomes (macro hairs, micro hairs, and glandular hairs), as shown through the reduced and increased trichomes in their knockout and overexpression lines. We demonstrate that OsSCR1 acts upstream of OsWOX3B (WUSCHEL-RELATED HOMEOBOX 3B) in that overexpression of OsWOX3B could rescue the macro hair development defects in osscr1 osscr2 double mutants, and that OsSCR1 protein activates OsWOX3B expression using luciferase activity and chromatin immunoprecipitation quantitative PCR (ChIP-qPCR) assays. In addition, OsSPL10 (SQUAMOSA PROMOTER BINDING PROTEIN-LIKE10) acts upstream of OsSCR1 and enhances its expression to promote the development of macro and micro hairs. Additionally, increasing leaf trichome density through overexpressing OsSCR2 could enhance seedling resistance to locust feeding. Collectively, our findings indicate that OsSPL10 facilitates the process of OsSCR1 inducing OsWOX3B activity to promote the formation of macro and micro hairs in rice.","PeriodicalId":195,"journal":{"name":"Journal of Integrative Plant Biology","volume":" ","pages":""},"PeriodicalIF":9.3,"publicationDate":"2025-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144758813","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 described OsPLATZ1 as a transcriptional activator, a member of the Plant AT-rich sequence- and Zinc-binding family proteins in rice that positively regulates grain length. OsPLATZ1 interacted with multiple GRFs, and the OsPLATZ1-OsGRF4 complex bound to regulatory regions in the promoter of the G-protein gene DENSE AND ERECT PANICLE1 (DEP1) to enhance its expression, thereby regulating grain length. We used gene editing to modify the OsPLATZ1 promoter regulatory region and obtained mutant lines with downregulated or upregulated OsPLATZ1 expression depending on the type of editing event. One of these mutant lines had changes in multiple agronomic traits and improved grain yield and grain appearance quality.

Furthermore, the MdWOX8-MdHY5 module is a crucial hub linking SL and GA signals by interacting with the SL signaling repressor SUPPRESSOR OF MORE AXILLARY GROWTH 2-LIKE 8 (MdSMXL8) and the GA signaling repressor REPRESSOR-of-ga1-3-LIKE 3a (MdRGL3a). MdSMXL8 inhibits the activation of the MdHY5 promoter by MdWOX8, and MdRGL3a promotes the function of MdWOX8 by enhancing its transcriptional activation of MdHY5 and disrupting the MdSMXL8-MdWOX8 interaction. Moreover, the E3 ubiquitin ligase SEVEN IN ABSENTIA 1 (MdSINA1) negatively regulates MdWOX8 homeostasis by targeting it for ubiquitination and degradation in response to SL and GA signals.

However, the dynamics of cytonuclear interaction during crop domestication have still been rarely investigated. Here, we examine cytonuclear interactions during grapevine domestication using pan-mitogenome, pan-plastome, and haplotype-resolved nuclear genomes, all assembled from long-read sequences across 33 wild and domesticated grapevine accessions. Structural variation shaped the mitogenomic variation in gene contents, leading to duplications of three specific genes during grapevine domestication (one cox and two rpl genes). Extensive genomic signals of cytonuclear interactions were detected, including a total of 212-431 nuclear-mitochondrial segments (NUMTs) and 95-205 nuclear-plastid segments (NUPTs). These results showed that NUMTs were under strong selection and were more abundant in cultivated grapes, whereas NUPTs dominated in wild grapes, indicating the evolutionary trajectories of cytonuclear interactions during grape domestication. Through Genome-Wide Association Study (GWAS), we identified 84 candidate genes associated with mitochondrial-nuclear genome interactions. Among these, the PFD1 gene acts as a signaling regulator, modulating specific signaling pathways regulated by the mitochondria. Interestingly, there are significantly more cytonuclear interaction genes near NUMTs than in other genomic regions, suggesting NUMT-mediated interactions between the nuclear and mitochondrial genomes. Overall, our study provides evidence that NUMTs promote cytonuclear interaction during grapevine domestication, offering new insight into the impact of cytonuclear interactions on plant evolution, genetics, and breeding.","PeriodicalId":195,"journal":{"name":"Journal of Integrative Plant Biology","volume":" ","pages":""},"PeriodicalIF":9.3,"publicationDate":"2025-07-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144726251","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}

Liguleless1 (LG1) acts as a key regulator of LA and TBA, yet its precise regulatory mechanism remains largely obscure. In this study, we have identified ZmTCP23, a teosinte branched1/CYCLOIDEA/proliferating cell factors (TCP) transcription factor that is highly expressed in tassel and leaf primordia, serving as a pivotal upstream transcriptional regulator of LG1. The functional loss of ZmTCP23 results in a significant reduction in both TBA and LA ranges. Moreover, in vitro and in vivo studies revealed that LG1 directly represses the expression of ZmXERICO1, a gene encoding an inhibitor of abscisic acid (ABA) degradation that can also influence LA and TBA upon overexpression. Additionally, ZmTCP23 physically interacts with the previously identified TBA regulator BAD1, forming a complex that co-activates the expression of LG1 via direct binding to its promoter. This dynamic duo established a positive feedback loop, mutually enhancing each other's expression within the tassels, and consequently influencing TBA. Our findings establish a ZmTCP23-LG1-ZmXERICO1 transcriptional regulatory cascade that orchestrates LA and TBA through influencing ABA content, and provide new targets for the genetic manipulation of LA and TBA for molecular breeding of high-density tolerant maize cultivars.","PeriodicalId":195,"journal":{"name":"Journal of Integrative Plant Biology","volume":" ","pages":""},"PeriodicalIF":9.3,"publicationDate":"2025-07-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144726253","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}

Under salt stress, plants can transport sodium ions (Na+) out of cells and sequester them into vacuoles for detoxification. The salt excretion process is governed by the SALT OVERLY SENSITIVE (SOS) pathway, which involves the calcium sensors SOS3 and SOS3-LIKE CALCIUM BINDING PROTEIN 8, the protein kinase SOS2, and the plasma membrane Na+/H+ antiporter SOS1. While previous studies have provided insights into Na+ transport through the SOS system, the role of this pathway in Na+ compartmentalization within vacuoles remains poorly understood. In this study, we demonstrate that SOS1 partially internalizes to the tonoplast under salt stress, which is crucial for Na+ compartmentalization in vacuoles in Arabidopsis (Arabidopsis thaliana). We show that SOS2 phosphorylates the endosomal sorting complex required for transport-I (ESCRT-I) component FYVE DOMAIN PROTEIN REQUIRED FOR ENDOSOMAL SORTING 1 (FREE1), which disrupts its interaction with VPS23A, an ESCRT-I component. This phosphorylation event inhibits the formation of intraluminal vesicles (ILVs) in prevacuolar compartments and multivesicular bodies (PVCs/MVBs), thereby remodeling endosomal sorting during salt stress. Additionally, our previous research indicated that SOS2-mediated phosphorylation of FREE1 leads to vacuole fragmentation by altering endomembrane fusion, thereby regulating intracellular Na+ homeostasis. Taken together, our findings reveal how the SOS2-FREE1 module orchestrates both endomembrane fusion and endosome sorting processes to enhance plant salt tolerance, providing novel insights into the cellular mechanisms underlying salt stress adaptation.","PeriodicalId":195,"journal":{"name":"Journal of Integrative Plant Biology","volume":" ","pages":""},"PeriodicalIF":9.3,"publicationDate":"2025-07-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144688485","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}

They are also ecologically important, dominating many temperate and tropical ecosystems. Great progress in understanding rosid phylogenetic relationships has facilitated evolutionary studies, but phylogenetic uncertainties remain. To construct a more comprehensive nuclear phylogeny with expanded taxon coverage at the familial levels, we generated 203 new transcriptomes and two shotgun genomes. Along with other available data sets, our sample includes 419 eudicots, including 316 rosids, representing 83 families and all 16 rosid orders. Compared to the 1KP study, our highly resolved rosid phylogeny provides strongly supported internal relationships for one additional order and 16 families. We uncovered cytoplasmic-nuclear discordance for several deep rosid relationships with possible evidence of hybridization/gene flow and incomplete lineage sorting. By tracing ancestral states of morphological characters, we revealed putative floral evolutionary trends in some major clades. We detected strong evidence for 27 putative whole-genome duplication (WGD) events distributed across 20 rosid families, including five novel WGDs. Additionally, our expanded taxon sampling allowed for revised phylogenetic positions of several previously reported WGD events. Most of the supported WGDs correspond to origins of families or large subclades and occurred near times of geological and global climate upheavals, including those at the Cretaceous-Paleogene boundary. Our findings support the idea that large-scale genomic changes and key morphological innovations might have contributed to adaptive evolution and increased biodiversity in rosids.","PeriodicalId":195,"journal":{"name":"Journal of Integrative Plant Biology","volume":" ","pages":""},"PeriodicalIF":9.3,"publicationDate":"2025-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144648092","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}
