While ethylene and abscisic acid (ABA) are known to synergistically regulate anthocyanin biosynthesis via transcription factors (TFs) in plants, their regulatory roles in M. 'Profusion' under rust stress remain elusive. In this study, we found that the release of ABA and ethylene significantly increased during rust infection. Crucially, we identified MpbZIP46, a novel ABA-responsive bZIP TF, as playing a key role in anthocyanin biosynthesis. Overexpression of MpbZIP46 significantly promoted anthocyanin synthesis, while CRISPR/Cas9-mediated knockdown of MpbZIP46 significantly reduced anthocyanin content. Further studies showed that under rust conditions, the release of ABA and ethylene synergistically promoted the accumulation of anthocyanins in M. 'Profusion' rust spots. Mechanistically, MpbZIP46 physically interacts with the ethylene-responsive TF MpERF105, forming a functional complex that synergistically transactivates the promoter of MpMYB10b-the core regulator of anthocyanin synthesis, thereby driving anthocyanin production in rust-stressed leaves.

In this study, we used modified sorghum plants silenced in the main PEPC isozyme in roots, SbPPC3, and analyzed the role of PEPC in the presence of insoluble calcium phosphate (PCa), showing a phosphate starvation phenotype in silenced but not in WT plants. Interestingly, root exudation of citrate was not reduced in silenced plants, probably due to a higher citrate synthase activity, but it was reduced for succinate, another compound with phosphate solubilisation capacity. Finally, silenced plants accumulated less P in roots with PCa, leading to a reduced phosphate acquisition efficiency (PAE).

Although Trichoderma koningiopsis improves damping-off disease resistance in Masson pine by regulating the rhizosphere microbial community, the underlying mechanisms remain unknown. Metabolomic analysis showed that T. koningiopsis altered Masson pine root exudates, especially plant organic acids such as capric acid (CA), lauric acid (LA) and pelargonic acid (PA). Co-culturing rhizosphere microbes with 0.1 mM CA, LA, PA and a combination of the three (1:1:1, CDNs1) significantly inhibited F. oxysporum and promoted the growth of rhizosphere biocontrol strains (Trichoderma, Penicillium and Bacillus), with CDNs1 exerting a superior effect. Amplicon sequencing and RT-qPCR showed that CDNs1 significantly altered the microbial community composition in the rhizosphere, especially inhibited the growth of Fusarium and enriched beneficial microbes (Trichoderma and Penicillium). CDNs1 effectively decreased the incidence and severity index of damping-off disease in Masson pine seedlings by 73.33% and 41.67%, respectively. Mechanistically, CDNs1 enhanced resistance to damping-off disease by modulating plant hormones, oxidative stress defences and the photosynthesis pathway.

Despite its important contribution to plant RNA metabolism, the direct impact of DXO1 enzymatic activity on cellular processes appears surprisingly limited. Notably, most molecular and morphological changes observed so far in dxo1 mutant plants depended on the plant-specific N-terminal domain of the protein. Our investigation into the role of DXO1 in response to biotic stress, specifically its susceptibility to Pseudomonas syringae pv. tomato DC3000 infection, unexpectedly revealed the importance of DXO1 enzymatic activity in the plant immune response. We observed that dxo1-2 knockout mutant and transgenic dxo1-2 lines expressing a DXO1 variant either catalytically inactive or lacking the N-terminal domain exhibited enhanced resistance to Pst, accompanied by marked changes in the expression of key pathogenesis markers. Also, other markers of plant immunity, such as callose deposition and production of reactive oxygen species, were strongly induced by PAMPs elf18 and flg22. These results strongly suggest that both DXO1 features, the N-terminal domain and its catalytic site, contribute to the regulation of plant immunity. This is the first observation revealing the involvement of DXO1 enzymatic activity in plant physiology. Moreover, our analyses showed that dxo1-2 mutation altered the expression of a large group of defense-related genes, affected the stability of mRNAs, and delayed the activation of MAP kinases. Therefore, we postulate that DXO1 protein deregulates defense against Pst infection at both the transcriptional and posttranscriptional levels.</p>","PeriodicalId":222,"journal":{"name":"Plant, Cell & Environment","volume":" ","pages":""},"PeriodicalIF":6.3,"publicationDate":"2025-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145129755","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}

Cytokinins are important endogenous signalling molecules in plants and play a critical role in regulating stress responses. However, the mechanism by which cytokinins mediate cold stress responses in rice seedlings remains unclear. In this study, we employed cold-tolerant and cold-sensitive rice cultivars, cytokinin-defective mutants and exogenous cytokinin supplementation to elucidate the mechanisms underlying cytokinin-mediated chilling adaptation. First, we compared the transcriptomic and metabolomic profiles of a cold-tolerant cultivar (HY73) and a cold-sensitive cultivar (WFY286) under low-temperature treatment (11°C for 8 h). The results revealed that cytokinins, along with energy metabolic pathways such as glycolysis and the tricarboxylic acid cycle, are closely associated with cold tolerance in rice seedlings. Compared with WFY286, HY73 presented higher levels of root-derived trans-zeatin (tZ)-type cytokinins in leaves, increased energy metabolism, elevated ATP content and increased energy charge. Furthermore, the tZ-type cytokinins transport-deficient mutant abcg18 presented reduced cold tolerance, lower energy metabolic activity and decreased ATP and energy charge levels, indicating that the transport of tZ-type cytokinins is crucial for cold stress responses. Leaf spraying with tZ significantly improved the energy metabolism and cold tolerance of WFY286 and abcg18. Taken together, our findings suggest that root-derived tZ-type cytokinins enhance low-temperature adaptation in rice seedlings by promoting energy metabolism and maintaining cellular energy homoeostasis.
