The WRKY web, which is comprised of a subset transcription factors (TFs), plays crucial role in the regulation plant immunity, however, mode organization and operation this network remains obscure, especially non-model plants such as pepper (Capsicum annuum). Herein, CaWRKY22, member subgroup IIe proteins from pepper, was functionally characterized immunity against Ralstonia Solanacearum. CaWRKY22 found to target nuclei, its transcript level significantly upregulated by Solanacearum...
Ustilaginoidea virens, the causal agent of rice false smut (RFS), has become one most devastating pathogens worldwide. As a group essential virulence factors, effectors in filamentous fungus might play central roles interaction between plants and pathogens. However, little is known about individual U. virens virulence. In this study, we identified characterized small secreted cysteine-rich effector, SCRE2, virens. SCRE2 was first confirmed as an effector through yeast secretion, protein...
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...
Rice false smut caused by Ustilaginoidea virens has become one of the most important rice diseases. U. specifically infects florets through stamen filaments. However, it is mysterious how inhibits floral immunity for successful colonization. Here, we show that a small cysteine-rich effector SCRE9 key virulence factor in virens. Expression not only suppresses immune responses and resistance, but also significantly increases expression expansin gibberellin (GA) biosynthetic genes GA content...
Rice false smut, caused by the ascomycete fungus Ustilaginoidea virens, which infects rice florets before heading, severely threatens grain yield and quality worldwide. The U. virens genome encodes a number of glycoside hydrolase (GH) proteins. So far, functions these GHs in are largely unknown. In this study, we identified GH42 protein secreted named UvGHF1, that exhibits β-galactosidase activity. UvGHF1 not only as an essential virulence factor during infection, but also serves...
SUMMARY Plants have evolved a sophisticated immune system to defend against invasion by pathogens. In response, pathogens deploy copious effectors evade the responses. However, molecular mechanisms used pathogen suppress plant immunity remain unclear. Herein, we report that an effector secreted Ralstonia solanacearum , RipAK, modulates transcriptional activity of ethylene‐responsive factor ERF098 and dehydration tolerance, which causes bacterial wilt in pepper ( Capsicum annuum L.) plants....
Mitogen-activated protein kinase (MAPK) cascades play pivotal roles in plant defense against phytopathogens downstream of immune receptor complexes. The amplitude and duration MAPK activation must be strictly controlled, but the underlying mechanism remains unclear. Here, we identified Arabidopsis CPL1 (C-terminal domain phosphatase-like 1) as a negative regulator microbe-associated molecular pattern (MAMP)-triggered immunity via forward-genetic screen. Disruption significantly enhanced...
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...
ChiIV3, a chitinase of pepper (Capsicum annuum), stimulates cell death in plants. However, there are only scarce reports on its role resistance against bacterial wilt disease such as that caused by Ralstonia solanacearum and their transcriptional regulation. In this study, the silencing ChiIV3 plants significantly reduced to R. solanacearum. The transcript was induced inoculation (RSI) well exogenous application methyl jasmonate abscisic acid. bioinformatics analysis revealed promoter...
