Abstract Many phytopathogens secrete cell wall degradation enzymes (CWDEs) to damage host cells and facilitate colonization. As the major components of plant wall, cellulose hemicellulose are targets CWDEs. Damaged often release damage-associated molecular patterns (DAMPs) trigger immune responses. Here, we establish that fungal pathogen Magnaporthe oryzae secretes endoglucanases MoCel12A MoCel12B during infection rice ( Oryza sativa ). These target two specific oligosaccharides, namely...
To defend against pathogens, plants have developed complex immune systems, including plasma membrane receptors that recognize pathogen-associated molecular patterns, such as chitin from fungal cell walls, and mount a defense response. Here, we identify chitinase, MoChia1 (Magnaporthe oryzae chitinase 1), secreted by M. oryzae, pathogen of rice (Oryza sativa). can trigger plant responses, expression under an inducible promoter in enhances its resistance to is functional required for growth...
The latest report has estimated the number of rice genes to be ∼32 000. To elucidate functions a large population and search efficiently for agriculturally useful genes, we have been taking advantage Full-length cDNA Over-eXpresser (FOX) gene-hunting system. This system is very analyzing various gain-of-function phenotypes from populations transgenic plants overexpressing cDNAs interest others with unknown or important functions. We collected plasmid DNAs 13 980 independent full-length...
Gossypium barbadense is a cultivated cotton species and possesses many desirable traits, including high fiber quality resistance to pathogens, especially Verticillium dahliae (a devastating pathogen of hirsutum, the main species). These elite traits are difficult be introduced into G. hirsutum through classical breeding methods. In addition, genetic transformation has not been successfully performed. It therefore important develop methods for evaluating function molecular mechanism genes in...
Abstract Crosstalk between plant hormone signaling pathways is vital for controlling the immune response during pathogen invasion. Salicylic acid (SA) and jasmonic (JA) often play important but antagonistic roles in responses of higher plants. Here, we identify a basic helix‐loop‐helix transcription activator, OsbHLH6, which confers disease resistance rice by regulating SA JA via nucleo‐cytosolic trafficking ( Oryza sativa ). OsbHLH6 expression was upregulated Magnaporthe oryzae infection....
Endoplasmic reticulum (ER) homeostasis is essential for plants to manage responses under environmental stress. Plant immune activation requires the ER, but how ER associated with plant largely unexplored. Here we find that transcription of an HVA22 family gene, OsHLP1 (HVA22-like protein 1), induced by Magnaporthe oryzae infection. Overexpression significantly enhances blast disease resistance impairs morphology in rice (Oryza sativa), resulting enhanced sensitivity interacts NAC (NAM, ATAF,...
Polyamines (PAs) play diverse roles in plant growth and development, as well responses to environmental stimuli. In this study, the effects of PAs on rice salt tolerance were investigated. Salt stress resulted alteration endogenous levels roots leaves, where spermidine (Spd) spermine (Spm) contents increased, putrescine (Put) content was decreased. RT-qPCR analysis revealed that biosynthesis-related genes ADC1, ODC, Arginase significantly downregulated by treatment; however, SAMDC...
Seed germination is a key developmental process in the plant life cycle that influenced by various environmental cues and phytohormones through gene expression series of metabolism pathways. In present study, we investigated C2C2-type finger protein, OsLOL1, which promotes gibberellin (GA) biosynthesis affects seed Oryza sativa (rice). We used OsLOL1 antisense sense transgenic lines to explore functions. timing plants was restored wild type when exogenous GA3 applied. The reduced GA OsKO2...
Significance The ethylene signaling pathway has been extensively investigated in Arabidopsis , and EIN2 is the central component. Rice a monocotyledonous model plant that exhibits different features many aspects compared with dicotyledonous . Thus, rice provides an alternative system for identification of novel components signaling. In this study, we identified stabilizer OsEIN2 through analysis ethylene-insensitive mutant mhz3 We found MHZ3 stabilizes likely by binding to its Nramp-like...
We applied the full-length cDNA overexpressor (FOX) gene-hunting system for systematic and genome-wide functional analysis of rice genes. In this study, we constructed a novel binary vector carrying Gateway site-specific recombination cassette then FOX libraries containing maximum 13,823 independent, cDNAs (fl-cDNAs) that correspond to approximately half total number fl-cDNA clones. By introducing via Agrobacterium, generated 2,586 FOX-rice lines exhibiting various visible alterations (e.g.,...
Abstract BACKGROUND: The Colorado potato beetle (CPB), Leptinotarsa decemlineata Say, is a destructive pest. CPB quarantine pest in China, but has now invaded the Xinjiang Uygur Autonomous Region and continuing to spread eastwards. To control damage overspreading, transgenic plants expressing Cry3A toxin were developed, their resistance was evaluated by bioassays laboratory field 2009, 2010 2011. RESULTS: insect of high‐dose (HD) lines significantly greater than middle‐dose (MD) low‐dose...
RNA interference (RNAi) has been developed for plant pest control. In this study, hairpin-type double-stranded (dsRNA) targeting the juvenile hormone (JH) acid methyltransferase (JHAMT) gene (dsJHAMT) was introduced in potato plants via Agrobacterium-mediated transformation. The results indicated that transcriptional of dsJHAMT accumulated transgenic plants. transcripts and proteins L. decemlineata JHAMT were significantly reduced larvae feeding on foliage. had a significant negative effect...
