Insertional mutagenesis of Arabidopsis ecotype C24 was used to identify a novel mutant, designated wax2, that had alterations in both cuticle membrane and cuticular waxes. mutants with altered have not been reported previously. Compared the wild type, wax2 stems weighed 20.2% less, when viewed using electron microscopy, it 36.4% thicker, less opaque, structurally disorganized. The total wax amount on leaves reduced by >78% showed proportional deficiencies aldehydes, alkanes, secondary...
Ubiquitin-regulated protein degradation is a critical regulatory mechanism that controls wide range of biological processes in plants. Here, we report OsDIS1 (for Oryza sativa drought-induced SINA 1), C3HC4 RING finger E3 ligase, involved drought-stress signal transduction rice (O. sativa). The expression was up-regulated by drought treatment. In vitro ubiquitination assays showed possessed ubiquitin ligase activity and the conserved region required for activity. Transient Nicotiana...
Rice blast and bacterial blight are important diseases of rice (Oryza sativa) caused by the fungus Magnaporthe oryzae bacterium Xanthomonas pv. (Xoo), respectively. Breeding varieties for broad-spectrum resistance is considered most effective sustainable approach to controlling both diseases. Although dominant genes have been extensively used in breeding production, generating disease-resistant altering susceptibility (S) that facilitate pathogen compatibility remains unexplored. Here, using...
The absorption of nutrients and disease resistance are two indispensable physiological processes in plants; however, it is still largely unknown whether there cross-talk between their molecular signaling pathways. In this study, we identified the rice OsPT8 protein, which a member phosphate transporters (PTs) Pht1 family also plays role resistance. transcriptional level suppressed after infection with pathogens treatment pathogen-associated patterns (PAMPs). Overexpression suppresses against...
Utilization of broad-spectrum resistance (R) genes is an effective and economical strategy to control the fungal pathogen Magnaporthe oryzae, causal agent rice blast disease. Among cloned genes, Pi9, Pi2 Piz-t confer diverse M. oryzae isolates were isolated from Pi2/9 locus on chromosome 6. Identification isolation additional R with different spectra this will provide novel genetic resources for better important disease.In study, we identified a dominant gene, Pi2-2, at Jefferson, elite U.S....
The indica rice cultivar Xiangzi 3150 (XZ3150) confers a high level of resistance to 95% the isolates Magnaporthe oryzae (the agent blast disease) collected in Hunan Province, China. To identify (R) gene(s) controlling this cultivar, we developed 286 F(9) recombinant inbred lines (RILs) from cross between XZ3150 and highly susceptible CO39. Inoculation RILs an F(2) population two cultivars with avirulent isolate 193-1-1 growth chamber indicated presence dominant R genes XZ3150. A linkage map...
Abstract Insertional mutagenesis of Arabidopsis (Arabidopsis thaliana) was used to identify a novel recessive mutant, designated resurrection1 (rst1), which possesses dramatic alteration in its cuticular waxes and produces shrunken nonviable seeds due arrested embryo development. The RST1 gene sequence associated with these phenotypes verified by three independent, allelic, insertion mutants, rst1-1, rst1-2, rst1-3, inserts the first exon, 12th intron, fourth respectively. These rst1 allelic...
Tianjingyeshengdao' (TY) is a rice cultivar with durable resistance to populations of Magnaporthe oryzae (the causal agent blast) in China. To understand the genetic basis its blast, we developed population recombinant inbred lines from cross between TY and highly susceptible 'CO39' for gene mapping analysis. In total, 22 quantitative trait loci (QTLs) controlling blast were identified on chromosomes 1, 3, 4, 5, 6, 9, 11, 12 evaluation four disease parameters both greenhouse nursery...
To make better use of global germplasm resources for improving the eating quality hybrid rice, using resequencing data from 3,000 rice genomes project (3K RGP), allelic variations Wx locus were analysed. With exception five rare alleles discovered first time in our study, most these known Wx. Furthermore, a set Kompetitive allele-specific PCR (KASP) markers based on have been developed, and thirty-six main parents 1976 to 2018 selected genotyping. The results showed that only three existed...
The germination of seeds is a prerequisite for crop production. Protrusion important seed germination, and visible radicle protrusion through covering layers the second phase process germination. Analyzing mechanism cultivation rice varieties. In this study, 302 microcore germplasm populations were used GWAS percentage (PP). frequency distribution PP at 48 h 72 continuous, six PP-associated QTLs identified, but only qPP2 was detected repeatedly two times. candidate gene analysis showed that...
Plants NADP-malic enzymes (NADP-MEs) act as a class of oxidative decarboxylase to mediate malic acid metabolism in organisms. Despite NADP-MEs have been demonstrated play pivotal roles regulating diverse biological processes, the role involving plant growth and development remains rarely known. Here, we characterized function rice cytosolic OsNADP-ME2 height. The results showed that RNAi silencing knock-out dwarf structure, associating with significant expression inhibition genes...
Cold tolerance at the bud burst stage (CTB) is a key trait for direct-seeded rice. Although quantitative loci (QTL) affecting CTB in rice have been mapped using traditional linkage mapping and genome-wide association study (GWAS) methods, underlying genes remain unknown. In this study, we evaluated phenotype of 339 cultivars Rice Diversity Panel II (RDP II) collection. GWAS identified four QTLs associated with (qCTBs), distributed on chromosomes 1-3. Among them, qCTB-1-1 overlaps...
In this study,35 blast strains,rice lines including the donors of resistant genes and rice transgenic with genetic background Nipponbare were employed for antimicrobial spectrum analysis three Pi9,Pi2 Pizt.The results showed that Pi9 Pi2 both have a broad resistance frequency 94.2%,while Pizt narrow only 60%.The strains ROR1,X2007A–7 are compatible to Pi9,and CHNOS60–2–3,RB14 Pi2.In addition,13 pairs SSR markers used diversity 20 out 35 strains,the these classified into 4 lineages which...
