• The rice–rice blast pathosystem is of great interest, not only because the damaging potential rice to crop, but also both pathogen and its host are experimentally amenable. resistance gene Pik, which one five classical alleles located at Pik locus on long arm chromosome 11, confers high stable many Chinese isolates. isolation functional characterization were performed in present study through genetic genomic approaches. A combination Pik-1 Pik-2 required for expression resistance. Both...
Abstract The resistance (R) gene Pi37, present in the rice cultivar St. No. 1, was isolated by an silico map-based cloning procedure. equivalent genetic region Nipponbare contains four nucleotide binding site–leucine-rich repeat (NBS–LRR) type loci. These candidates for Pi37 (Pi37-1, -2, -3, and -4) were amplified separately from 1 via long-range PCR, cloned into a binary vector. Each construct individually transformed highly blast susceptible Q1063. subsequent complementation analysis...
The indica rice variety Kasalath carries Pi36, a gene that determines resistance to Chinese isolates of blast and has been located 17-kb interval on chromosome 8. genomic sequence the reference japonica Nipponbare was used for an in silico prediction (R) content hence identification candidate gene(s) Pi36. Three such sequences, which all had both nucleotide-binding site leucine-rich repeat motif, were present. three genes amplified from DNA number varieties by long-range PCR, resulting...
Abstract Magnaporthe oryzae ( Mo ) is the causative pathogen of damaging disease rice blast. The effector gene AvrPib , which confers avirulence to host carrying resistance Pib was isolated via map-based cloning. encodes a 75-residue protein, includes signal peptide. Phenotyping and genotyping 60 isolates from each five geographically distinct populations revealed that frequency virulent isolates, as well sequence diversity within increased low level in far northeastern region China much...
Pik-h, an allele of Pik, confers resistance against the rice blast pathogen Magnaporthe oryzae. Its positional cloning has shown that it comprises a pair NBS-LRR genes, Pikh-1 and Pikh-2. While appears to be constitutively transcribed, transcript abundance Pikh-2 responds challenge. The CC (coiled coil) domain interacts directly with both AvrPik-h Transient expression assays demonstrated mediates initiation host defence response. Nucleocytoplasmic partitioning is required for their...
A stepwise mutation that occurred in both pathogens and their respective hosts has played a seminal role the co-evolutionary arms race evolution diverse pathosystems. The process driven by rice blast AvrPik Pik alleles was investigated through population genetic evolutionary approaches. diversity of non-signal domain higher than its signal peptide domain. Positive selection for particular northeastern region China stronger south. perfect relationship between functional lineages...
Rice blast is one of the most destructive diseases rice. This study was undertaken to identify rice resistance gene(s) in indica cultivar Kasalath. 'Kasalath' crossed with 9 12 Japanese differential cultivars, each carrying a single gene at seven known loci. Allelism tests were performed F 2 populations races. The controlled by two dominant genes different nonallelic nine six loci, Pi-a, Pi-i, Pi-k, Pi-ta, Pi-b, and Pi-t, an allele Pi-z locus. For detected locus, allelism test using race...
ABSTRACT The Chinese native cv. Q14 expresses a high level of resistance to many isolates Pyricularia grisea collected from Japan, Thailand, and China. was crossed an indica-susceptible cultivar, Q61. To rapidly determine the chromosomal location major gene present in linkage analysis using microsatellite markers performed F(2) population segregating 3R:1S (resistant/susceptible) through bulked-segregant (BSA) combination with recessiveclass (RCA). A total 189 selected each chromosome...
Pik-p is carried by cv. K60, which one of the Japanese differentials widely used in both Japan and China since 1980s. Its utility specificity was evaluated with a total 612 isolates Magnaporthe oryzae collected from various regions combination 16 main resistance genes being breeding programs. an independently dominantly acting gene Pik cluster, conditions differential reactions against many contains higher Guangdong, Jiangsu, Sichuan provinces, China, indicating that this could be still...
This paper introduces a new approach to analysis of spectra called asynchronous orthogonal sample design (AOSD). Specifically designed concentration series are selected according mathematical vectors. Based on the AOSD approach, interfering portion arising strictly from effect can be completely removed spectra. Thus, two-dimensional (2D) used as an effective tool characterize intermolecular interactions that lead apparent deviations Beer–Lambert law, even if characteristic peaks two...
Summary Plant resistance genes ( R genes) harbor tremendous allelic diversity, constituting a robust immune system effective against microbial pathogens. Nevertheless, few functional have been identified for even the best‐studied pathosystems. Does this limited repertoire reflect specificity, with most having defeated by former pests, or do plants rich diversity of genes, composite behavior which is yet to be characterized? Here, we survey 332 NBS ‐ LRR cloned from five resistant Oryza...
Jujube (family Rhamnaceae) is an important economic fruit tree in China. In this study, we reported 26 chloroplast (cp) sequences of jujube using Illumina paired-end sequencing. The sequence length cp genome was 161, 367-161, 849 bp, which composed a large single-copy region (89053-89437 bp) and small (19356-19362 separated by pair reverse repeat regions (26478-26533 bp). Each encodes the same 130 genes, including 112 unique being quite conserved structure gene sequence. A total 118 single...
The elite rice cultivar Yuejingsimiao 2 (YJ2) is characterized by a high level of grain quality and yield, resistance against Magnaporthe oryzae. YJ2 showed 100% to four fungal populations collected from Guangdong, Sichuan, Liaoning, Heilongjiang Provinces, which higher frequency than that shown the well-known (R) gene donor cultivars such as Sanhuangzhan 28zhan. Segregation analysis for with F(2) F(4) indicated was controlled multiple genes are dominant or recessive. putative R were roughly...
Rice blast, caused by the ascomycete Magnaporthe oryzae (Mo), imposes a major constraint on rice productivity. Managing disease through deployment of host resistance requires close understanding race structure pathogen population. The host/pathogen interaction between isolates sampled from four Mo populations collected across rice-producing regions China was tested using two established panels differential cultivars. clearest picture obtained Chinese cultivar panel, for which frequency...
