Plant Communications, Год журнала: 2022, Номер 3(3), С. 100318 - 100318

Опубликована: Март 25, 2022

Xanthomonas species colonize many host plants and cause huge losses worldwide. Transcription activator-like effectors (TALEs) are secreted by translocated into cells to manipulate the expression of target genes, especially oryzae pv. oryzicola, which bacterial blight leaf streak, respectively, in rice. In this review, we summarize progress studies on interaction between hosts, covering both rice other plants. TALEs not only key factors that make susceptible but also essential components plant resistance. Characterization TALE-like proteins has improved our understanding TALE evolution promoted development gene editing tools. addition, interactions hosts have provided strategies possibilities for genetic engineering crop improvement.

Summary Plants are simultaneously attacked by different pests that rely on sugars uptake from plants. An understanding of the role plant sugar allocation in these multipartite interactions is limited. Here, we characterized expression patterns sucrose transporter genes and evaluated impact targeted gene mutants brown planthopper (BPH) phloem‐feeding oviposition root BPH‐reduced rice susceptibility to Meloidogyne graminicola . We found OsSUT1 OsSUT2 induced at BPH sites. showed a higher resistance gravid than nymph BPH, this was correlated with callose deposition, as reflected effect M. infection. caused inhibition deposition counteracted oviposition. Meanwhile, pivotal validated cultivar RHT harbouring Bph3 Bph17 In conclusion, demonstrated regulated through differences allocation.

Ripening and rot: How ripening processes influence disease susceptibility in fleshy fruits

Journal of Integrative Plant Biology, Год журнала: 2024, Номер 66(9), С. 1831 - 1863

Fleshy fruits become more susceptible to pathogen infection when they ripen; for example, changes in cell wall properties related softening make it easier pathogens infect fruits. The need high-quality fruit has driven extensive research on improving resistance important crops such as tomato (Solanum lycopersicum). In this review, we summarize current progress understanding how during ripening affect by pathogens. These physical barriers that limit entry, the epidermis and its cuticle, along with other defenses growth, preformed induced defense compounds. plant immune system also protects recognizing initiating responses involving reactive oxygen species production, mitogen-activated protein kinase signaling cascades, jasmonic acid, salicylic ethylene, abscisic acid signaling. phytohormones regulate an intricate web of transcription factors (TFs) activate mechanisms, including expression pathogenesis-related genes. tomato, regulators, RIPENING INHIBITOR NON_RIPENING, not only but influence against Moreover, members ETHYLENE RESPONSE FACTOR (ERF) family play pivotal distinct roles defense, different being regulated phytohormones. We discuss interaction ripening-related defense-related TFs Mediator complex. As processes climacteric non-climacteric share many similarities, these have broad applications across fruiting crops. Further individual contributions ERFs will inform efforts diminish disease susceptibility ripe fruit, satisfy growing demand decrease food waste economic losses.

OsWRKY26 negatively regulates bacterial blight resistance by suppressing OsXa39 expression

Frontiers in Plant Science, Год журнала: 2025, Номер 15

Опубликована: Янв. 9, 2025

Plants are susceptible to infection by various pathogens with high epidemic potential. Xanthomonas oryzae pv. (Xoo) causes bacterial blight in rice, one of the most significant diseases both temperate and tropical regions. In this study, we report identification characterization OsWRKY26, a sucrose-inducible transcription factor, that plays role plant defense responses following Xoo infection. We found mutant plants defective OsWRKY26 showed enhanced response specifically Xoo, indicating factor acts as negative regulator. contrast, did not exhibit higher resistance compared wild-type (WT) when infected rice blast fungal pathogen Magnaporthe oryzae. Transcriptomic analysis WT revealed several genes were upregulated mutants. Of these, selected OsXa39 for further analysis. Transient expression experiments protoplasts repressed Luciferase reporter gene driven promoter. Chromatin immunoprecipitation binds directly promoter region OsXa39. These findings suggest negatively regulates during repressing well other pathogen-related such OsXa47, OsBBR1, OsRSR1, OsPR1a, OsPR1-11, OsPR2, OsPR4c.

WRKY36–PIL15 Transcription Factor Complex Negatively Regulates Sheath Blight Resistance and Seed Development in Rice

Plants, Год журнала: 2025, Номер 14(4), С. 518 - 518

Опубликована: Фев. 8, 2025

Sheath blight (ShB) causes severe yield loss in rice. Previously, we demonstrated that the sugar will eventually be exported and transporter 11 (SWEET11) mutation significantly improved rice resistance to ShB, but it caused defects seed development. The present study found WRKY36 PIL15 directly activate SWEET11 negatively regulate ShB. Interestingly, interacted with PIL15, activates miR530 a key BR signaling transcription factor WRKY53. AOS2 is an effector protein from Rhizoctonia solani (R. solani) interacts also for nutrition R. solani. These data collectively suggest WRKY36–PIL15 regulates ShB development via activation of miR530, respectively. In addition, are partners by which hijacks

Fumonisin B1 induces rapid programmed cell death in Arabidopsis cells, oxidative and nitrosative bursts, differentially modulates responsive genes. Glutathione is the main antioxidant involved stress response. (FB1) a fungal toxin produced by Fusarium spp. able to exert pleiotropic toxicity plants. FB1 known be strong inducer of (PCD); however, exact mechanism underling plant-toxin interactions molecular events that lead PCD are still unclear. Therefore, this work, we provided comprehensive investigation response model organism thaliana at nuclear, transcriptional, biochemical level after treatment with two different concentrations, namely 1 5 µM during time-course 96 h. induced bursts cultures, which resembled HR-like event. Different genes regulation PCD, metabolism, photosynthesis, pathogenesis, sugar transport were upregulated, especially late time higher concentration. Among enzymes compounds studied, only glutathione appeared highly both treatments, suggesting it might an important molecule exposure. Collectively, these findings highlight complexity signaling network A. provide information for understanding physiological, molecular, responses counteract FB1-induced toxicity.

Camellia oleifera CoSWEET10 Is Crucial for Seed Development and Drought Resistance by Mediating Sugar Transport in Transgenic Arabidopsis

Plants, Год журнала: 2023, Номер 12(15), С. 2818 - 2818

Опубликована: Июль 29, 2023

Sugar transport from the source leaf to sink organ is critical for seed development and crop yield, as well responding abiotic stress. SWEETs (sugar will eventually be exported transporters) mediate sugar efflux into reproductive are therefore considered key candidate proteins unloading during development. However, specific mechanism underlying seeds in Camellia oleifera remains elusive. Here, we identified a SWEET gene named CoSWEET10, which belongs Clade III has high expression levels of C. oleifera. CoSWEET10 plasma membrane-localized protein. The complementation assay SUSY7/ura3 EBY.VW4000 yeast strains showed that ability sucrose, glucose, fructose. Through vitro culture, found can induced by hexose especially glucose. By generating restoration lines Arabidopsis atsweet10, restored defect phenotype mutant regulating soluble accumulation increased plant drought tolerance. Collectively, our study demonstrates plays dual role promoting enhancing resistance sucrose transporter.
