Here, we defined a wheat MAPK cascade, composed of the mitogen-activated protein kinase kinase (MAPKK) TaMKK2 and its downstream MAPK TaMAPK6, which phosphorylates the core immune regulator TaSGT1 (suppressor of G2 allele of Skp1), resulting in enhanced nuclear entry of TaSGT1, thereby conferring resistance against the devastating wheat pathogen Puccinia striiformis f. sp. tritici (Pst). Hence, we identified a TaMKK2-TaMAPK6-TaSGT1 signaling cascade that contributes to wheat stripe rust resistance. During infection, Pst secrets a haustorium-associated secreted protein 215 (HASP215), that targets TaMKK2 and interferes with the interaction of TaMKK2 with TaMAPK6 to suppress TaMAPK6 phosphorylation and activation, thereby leading to reduced capacity of TaMAPK6 to phosphorylate TaSGT1. Consequently, inhibition of TaMAPK6-mediated TaSGT1 phosphorylation resulted in decreased nuclear translocation of TaSGT1 and suppressed plant immunity. Our work elucidates the positive function of TaMKK2-TaMAPK6 cascade in wheat immunity by regulating the immune component TaSGT1, and its regulation by the rust effector HASP215, providing new insights into the MAPK cascade on crop immunity and the pathogenicity mechanism of obligate biotrophic fungus.","PeriodicalId":195,"journal":{"name":"Journal of Integrative Plant Biology","volume":" ","pages":""},"PeriodicalIF":9.3,"publicationDate":"2025-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143584057","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 complexity of reconstructed SynComs often limits their application in sustainable agriculture. Furthermore, inter-strain interactions are often neglected during SynCom construction. Here, we propose a strategy for constructing a simplified and functional SynCom (sfSynCom) by using elite helper strains that significantly improve the beneficial functions of the core symbiotic strain, here Bradyrhizobium elkanii BXYD3, to sustain the growth of soybean (Glycine max). We first identified helper strains that significantly promote nodulation and nitrogen fixation in soybean mediated by BXYD3. Two of these helper strains assigned to the Pantoea taxon produce acyl homoserine lactones, which significantly enhanced the colonization and infection of soybean by BXYD3. Finally, we constructed a sfSynCom from these core and helper strains. This sfSynCom based on the core-helper strategy was more effective at promoting nodulation than inoculation with BXYD3 alone and achieved effects comparable to those of a complex elite SynCom previously constructed on the basis of potential beneficial functions between microbes and plants alone. Our results suggest that considering interactions between strains as well as those between strains and the host plant might allow construction of sfSynComs.","PeriodicalId":195,"journal":{"name":"Journal of Integrative Plant Biology","volume":" ","pages":""},"PeriodicalIF":9.3,"publicationDate":"2025-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143571589","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}

To adapt to and survive under hypoxic conditions, plants employ several physiological and molecular strategies that integrate morphological acclimation, metabolic shifts, and signaling networks. Group VII ETHYLENE RESPONSE FACTORS (ERF-VIIs), master transcription factors, have emerged as a molecular hub for regulating plant hypoxia sensing and signaling. Several mitogen-activated protein kinases and calcium-dependent protein kinases have recently been reported to be involved in potentiating hypoxia signaling via interaction with and phosphorylation of ERF-VIIs. Here, we provide an overview of the current knowledge on the regulatory network of ERF-VIIs and their post-translational regulation in determining plant responses to hypoxia and reoxygenation, with a primary focus on recent advancements in understanding how signaling molecules, including ethylene, long-chain acyl-CoA, phosphatidic acid, and nitric oxide, are involved in the regulation of ERV-VII activities. Furthermore, we propose future directions for investigating the intricate crosstalk between plant growth and hypoxic resilience, which is central to guiding breeding and agricultural management strategies for promoting flooding and submergence stress tolerance in plants.","PeriodicalId":195,"journal":{"name":"Journal of Integrative Plant Biology","volume":"67 3","pages":"440-454"},"PeriodicalIF":9.3,"publicationDate":"2025-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/jipb.13880","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143571603","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although the role of ER in plant immunity is evident, how ER homeostasis is associated with activation of the immune response remains unclear. Here, we report that StDMP2, an ER-localized member of the DOMAIN OF UNKNOWN FUNCTION 679 membrane protein (DMP) family, positively regulates resistance to Phytophthora in potato (Solanum tuberosum). Heterologous expression of StDMP2 in tobacco (Nicotiana benthamiana) also enhances resistance to Phytophthora. Furthermore, StDMP2 is involved in both chemical- and pathogen-induced ER stress responses. Notably, StDMP2 plays a crucial role in several pathogen-associated molecular pattern-triggered immunity responses, and specifically contributes to the hypersensitive response triggered by the bacterial type-III secreted effector AvrRpt2, but not the Phytophthora infestans-secreted effector Avr3a. Further investigation revealed that StDMP2 affects the ER quality control-mediated accumulation of specific pattern recognition receptors and NON-RACE SPECIFIC DISEASE RESISTANCE 1. Collectively, these findings elucidate a mechanism by which StDMP2 promotes plant immunity through modulating ER homeostasis.","PeriodicalId":195,"journal":{"name":"Journal of Integrative Plant Biology","volume":" ","pages":""},"PeriodicalIF":9.3,"publicationDate":"2025-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143571600","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}

A compact plant type reduces shading between plants, especially at high planting density, but also creates a humid microenvironment often associated with a higher incidence of pathogen and pest attacks, especially under highly humid climates. However, how to precisely manipulate the tiller angle to achieve a desirable plant type has been under-approached. Here we report the creation of gradient tiller angles in indica rice by fine tuning the expression of TILLER ANGLE CONTROL1 (TAC1), a domesticated gene in cultivated rice. We edited the regions upstream and downstream of the TAC1 coding sequence using multiplex CRISPR-Cas9 technology and developed homozygous allelic lines carrying deletions/inversions of various sizes at different positions. Those lines displayed smooth gradient changes in tiller angle that aligned well with TAC1 expression levels. Additionally, changes in the TAC1 expression level had no impact on other agronomic traits examined. TAC1 is well conserved across species, including perennial fruit trees in which mutation of TAC1 orthologs leads to a broomy plant type. Thus, our results provide a guide to creating tiller angles for selection according to climate zones in rice breeding programs, this approach can be extended to diverse species for improving plant architecture.","PeriodicalId":195,"journal":{"name":"Journal of Integrative Plant Biology","volume":" ","pages":""},"PeriodicalIF":9.3,"publicationDate":"2025-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143571602","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}
