Hyperosmolality triggers calcium signaling, and yet how osmotic-induced calcium signaling participates in cellular osmotic response remains enigmatic. To date, several Ca²⁺ channels and transporters have been identified to regulate osmotic-induced calcium signal generation (CaSG) or Ca²⁺ homeostasis. However, there has been no report on their function in calcium signal clearance (CaSC) in plants, especially in crops. Here, we investigated the role of a rice cation/calcium exchanger OsCCX2 in modulating calcium signaling dynamics using two distinct calcium reporters aequorin and GCaMP6s. The results showed that, under osmotic stress conditions, CaSC was significantly delayed in both root and guard cells of ccx2 mutants compared with the wild-type. Further studies revealed that hyperosmotic stress-triggered influxes of sodium (Na⁺), potassium (K⁺), and chloride (Cl^-) ions were significantly reduced in ccx2 mutants, resulting in a significantly smaller range of osmotic pressure and water potentials (Ψ_w) adjustment. In addition, the stomatal response was impaired, with a faster water loss in ccx2 in response to hyperosmotic stress. Furthermore, the absence of OsCCX2 altered the expression patterns of key osmotic-responsive genes, but their transcriptional activation was unaffected. Collectively, these changes ultimately led to reduced hyperosmotic stress tolerance in the mutants. Additionally, OsCCX2 is likely to be located in the endoplasmic reticulum and plasma membrane, and possess Na⁺/Ca²⁺ exchange activity. To sum up, our findings provide evidence that OsCCX2, as a CaSC regulator, is involved in cell osmotic adjustment, water homeostasis and osmotic stress tolerance in rice, which offers new insight into potential applications in drought-resistant crop improvement.</p>","PeriodicalId":195,"journal":{"name":"Journal of Integrative Plant Biology","volume":" ","pages":""},"PeriodicalIF":9.3,"publicationDate":"2025-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145005611","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, its yield is far below that of major cereal crops. The green revolution increased the yield of cereal crops partially through high-density planting of lodging-resistant semi-dwarf varieties, but required more nitrogen fertilizers, posing an environmental threat. Genes that can improve nitrogen use efficiency need to be integrated into semi-dwarf varieties to avoid the overuse of fertilizers without the loss of dwarfism. Unlike cereal crops, soybean can assimilate atmospheric nitrogen through symbiotic bacteria. Here, we created new alleles of GmGID1-2 (Glycine max GIBBERELLIN INSENSITIVE DWARF 1-2) using clustered regularly interspaced short palindromic repeats (CRISPR)/CRISPR-associated nuclease 9 (Cas9) editing, which improved soybean architecture, yield, seed oil content, and nitrogen fixation, by regulation of important pathways and known genes related to branching, lipid metabolism, and nodule symbiosis. GmGID1-2 knockout reduced plant height, and increased stem diameter and strength, number of branches, nodes on the primary stem, pods, and seeds per plant, leading to an increase in seed weight per plant and yield in soybean. The nodule number, nodule weight, nitrogenase activity, and nitrogen content were also improved in GmGID1-2 knockout soybean lines, which is novel compared with the semi-dwarf genes in cereal crops. No loss-of-function allele for GmGID1-2 was identified in soybean germplasm and the edited GmGID1-2s are superior to the natural alleles, suggesting the GmGID1-2 knockout mutants generated in this study are valuable genetic resources to further improve soybean yield and seed oil content in future breeding programs. This study illustrates the pleiotropic functions of the GID1 knockout alleles with positive effects on plant architecture, yield, and nitrogen fixation in soybean, which provides a promising strategy toward sustainable agriculture.</p>","PeriodicalId":195,"journal":{"name":"Journal of Integrative Plant Biology","volume":" ","pages":""},"PeriodicalIF":9.3,"publicationDate":"2025-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145005663","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}

Open stomata 1 (OST1), a key protein kinase in the abscisic acid (ABA) signaling cascade, has been established as a central regulator of stomatal dynamics. This study reveals that two highly conserved mitogen-activated protein kinase 1 (MAP4K1) and MAP4K2 are positive regulators in ABA promoted stomatal closure, and ABA-activated OST1 potentiates MAP4K1/2 through phosphorylation at conserved serine and threonine residues (S166, T170, and S479/S488). The activated MAP4K1, in turn, phosphorylates two critical downstream targets: plasma membrane H⁺-ATPase 2 (AHA2) at residues T858, T881, and Y946, and slow anion channel-associated 1 (SLAC1) at T114 and S116. Functional analysis demonstrates that the phosphomimetic (3D: S166D/T170D/S479D) MAP4K1, but not non-phosphorylatable (3A: S166A/T170A/S479A) MAP4K1, could fully restore drought tolerance and reduced water loss in detached leaves of map4k1map4k2 double mutant.

The recent and rapid radiation of the genus Aspidistra (cast-iron plant) provides an ideal system for examining these processes. Here, we generated restriction site-associated DNA sequencing data for 123 Aspidistra taxa and reconstructed well-resolved phylogenies using both concatenation- and coalescent-based approaches. Using a comprehensive suite of diversification models, we quantified the contributions of multiple biotic and abiotic factors and applied phylogenetic path analysis to detect their synergistic effects. Our phylogenetic analyses recovered two main clades that differ in stem habits. We found that the diversification of Aspidistra has been driven by both abiotic factors (paleotemperature and the East Asian monsoon) and biotic factors (interspecific competition and pollination mutualism). Notably, these drivers operated both independently and synergistically to facilitate the rapid radiation of Aspidistra. Beyond providing a robust phylogeny useful for classifying Aspidistra, we present a statistical framework for better understanding the macroevolutionary processes underlying rapid plant radiations. Our findings underscore the critical importance of integrating multiple biotic and abiotic drivers into a unified analytical framework to comprehensively understand diversification history.</p>","PeriodicalId":195,"journal":{"name":"Journal of Integrative Plant Biology","volume":" ","pages":""},"PeriodicalIF":9.3,"publicationDate":"2025-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144937389","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}

While the CLAVATA3/EMBRYO SURROUNDING REGION-related 19 (CLE19) peptide has been identified as a microspore-derived \"brake\" that restricts tapetal activity to maintain exine developmental homeostasis, how CLE19 integrates with hormonal signaling pathways remains poorly understood. Here, we demonstrate that CLE19 attenuates brassinosteroid (BR) signaling output by engaging a defined BSL-BIN2-BES1 signaling cascade. Through quantitative phosphoproteomic analysis, we identified that CLE19 affects the phosphorylation of multiple BR signaling components, including BSL-type phosphatases BSL1/2/3, the GSK3-like kinase BIN2, and the transcription factor BES1. We show that CLE19 is perceived by its receptor PXL1, which directly interacts with BSL-type phosphatases to activate the GSK3-like kinase BIN2, leading to phosphorylation of BES1 at serine residues S219 and S223. Functional analyses using phospho-dead and phospho-mimic BES1 variants confirm that CLE19-dependent phosphorylation controls BES1 nuclear export and degradation, ultimately suppressing BR-responsive transcriptional outputs required for pollen exine patterning.
