Abstract Rice false smut caused by Ustilaginoidea virens is emerging as a devastating disease of rice (Oryza sativa) worldwide; however, the molecular mechanisms underlying U. virulence and pathogenicity remain largely unknown. Here we demonstrate that small cysteine-rich secreted protein SCRE6 in translocated into host cells during infection factor. Knockout leads to attenuated rice. its homologs function novel family mitogen-activated kinase phosphatases harboring no canonical phosphatase...
The calcium-dependent protein kinase OsCPK4 has been demonstrated to play important roles in salt and drought tolerance, plant growth, development rice (Oryza sativa). However, little is known about molecular mechanisms underlying function immunity. In this study, we that the generation of oxidative burst pathogenesis-related gene expression triggered by microbe-associated patterns were significantly enhanced oscpk4 mutants. These mutant lines are more resistant bacterial blight fungal blast...
Abstract To dissect the signaling networks that orchestrate immune gene expression, we developed a sensitive genetic screen using an ethyl methanesulfonate (EMS)-mutagenized population of Arabidopsis transgenic plants. These plants carry early responsive FRK1 (flg22-induced receptor-like kinase 1) promoter fused with luciferase (LUC) reporter. A series mutants altered pFRK1::LUC activity were identified and named as g enes overning i mmune e xpression ( aggie ). The aggie5 mutant showed...
Abstract Plant immunity is fine-tuned to balance growth and defense. However, little yet known about molecular mechanisms underlying immune homeostasis in rice (Oryza sativa). In this study, we reveal that a calcium-dependent protein kinase (CDPK), OsCPK17, interacts with stabilizes the receptor-like cytoplasmic (RLCK) OsRLCK176, close homolog of Arabidopsis thaliana BOTRYTIS-INDUCED KINASE 1 (AtBIK1). Oxidative burst pathogenesis-related gene expression triggered by pathogen-associated...
Xanthomonas campestris pv. (Xcc) causes black rot, one of the most important diseases brassica crops worldwide. The type III effector inventory plays roles in virulence and pathogenicity pathogen. However, little is known about function(s) putative AvrXccB Xcc. Here, we investigated immune suppression ability possible underlying mechanisms. was demonstrated to be secreted a secretion system-dependent manner. tagged with green fluorescent protein localized plasma membrane Arabidopsis,...
Plant cells recognize microbial patterns with the plasma-membrane-localized pattern-recognition receptors consisting mainly of receptor kinases (RKs) and receptor-like proteins (RLPs). RKs, such as bacterial flagellin FLS2, their downstream signaling components have been studied extensively. However, newly discovered regulatory RLP-mediated immune signaling, nlp20 RLP23, await identification. Unlike RLPs lack a cytoplasmic kinase domain, instead recruiting (RLKs) BAK1 SOBIR1. SOBIR1...
Rice false smut caused by the biotrophic fungal pathogen Ustilaginoidea virens has become one of most important diseases in rice. The large effector repertory U. plays a crucial role virulence. However, current knowledge molecular mechanisms how effectors target rice immune signaling to promote infection is very limited. In this study, we identified and characterized an essential virulence effector, SCRE4 (Secreted Cysteine-Rich Effector 4), virens. was confirmed as secreted nuclear through...
Plant nucleotide-binding, leucine-rich repeat (NLR) immune receptors recognize pathogen effectors and activate defense. NLR genes can be non-functional in distantly related plants (restricted taxonomic functionality, RTF). Here, we enable Solanaceae gene function rice, soybean Arabidopsis by co-delivering sensor with their cognate NRC-type helper NLRs. In protoplasts plants, Solanum americanum Rpi-amr1, Rpi-amr3 pepper Bs2 NLRs confer effector responsiveness if co-expressed NRC Rice carrying...
