The Identification Of Genetic Synteny Between Lolium Perenne Chromosome 7 And Rice Chromosome 6 Genomic Regions That Have Major Effects On Heading-Date, I. P. Armstead, L. B. Turner, L. Skøt, I. S. Donnison, M. O. Humphreys, I. P. King
The Identification Of Genetic Synteny Between Lolium Perenne Chromosome 7 And Rice Chromosome 6 Genomic Regions That Have Major Effects On Heading-Date, I. P. Armstead, L. B. Turner, L. Skøt, I. S. Donnison, M. O. Humphreys, I. P. King
IGC Proceedings (1997-2023)
Comparative genetic mapping between plant species has established that there has been a conservation of genomic organisation which reflects evolutionary relationships. The genetic mapping of L. perenne has identified such syntenic relationships with both the Triticeae and rice. The recent publication of the complete sequence of the rice genome has allowed these relationships to be analysed more closely and has raised the possibility of using the rice genome as a template for chromosome landing-based gene identification in related non-model species. The aim of the present work was to map particular markers and genes associated with heading-date in rice in L. …
An In Silico Dna Sequence Comparison Of The Perennial Ryegrass And Rice Genomes, Marty J. Faville
An In Silico Dna Sequence Comparison Of The Perennial Ryegrass And Rice Genomes, Marty J. Faville
IGC Proceedings (1997-2023)
Comparative mapping studies in the family Poaceae, which includes rice (a model species for this family) and perennial ryegrass (PRG) have indicated macro-colinearity of genes is generally conserved across different genomes. Genome mapping of simple sequence repeat markers derived from expressed sequence tags (EST-SSRs) for PRG (Faville et al., 2004) provides a vehicle for DNA sequence-based matching of mapped PRG genes to orthologous positions in the rice genome, which can be used to establish comparative relationships between these species’ genomes. We have initiated such an analysis using an EST-SSR-based PRG genome map. Our objective was to assess this in …
Exploring The Effects Of Environmental Factors On Rice Blast Disease, April Ellen Lamb
Exploring The Effects Of Environmental Factors On Rice Blast Disease, April Ellen Lamb
Theses and Dissertations--Plant Pathology
Rice blast disease, caused by the ascomycete fungus Magnaporthe oryzae, occurs in over 85 countries and results in an annual crop loss of 10-30%, a corresponding nutrient value of meals for 60 million people. As a result, it is listed as a critical plant disease by the United Nations. Understanding factors affecting disease severity is of critical concern for food security. M. oryzae has been used as a model system for studying effector-triggered immunity (ETI) by understanding that ETI is primarily a plant response. M. oryzae has been used as a model to study fungal pathogenicity, host specificity, genome …
Gene Flow Between Divergent Cereal- And Grass-Specific Lineages Of The Rice Blast Fungus Magnaporthe Oryzae, Pierre Gladieux, Bradford Condon, Sebastien Ravel, Darren Soanes, Joao Leodato Nunes Maciel, Antonio Nhani, Li Chen, Ryohei Terauchi, Marc-Henri Lebrun, Didier Tharreau, Thomas Mitchell, Kerry F Pedley, Barbara Valent, Nicholas J.

Delineating species and epidemic lineages in fungal plant pathogens is critical to our understanding of disease emergence and the structure of fungal biodiversity and also informs international regulatory decisions. Pyricularia oryzae (syn. Magnaporthe oryzae) is a multihost pathogen that infects multiple grasses and cereals, is responsible for the most damaging rice disease (rice blast), and is of growing concern due to the recent introduction of wheat blast to Bangladesh from South America. However, the genetic structure and evolutionary history of M. oryzae, including the possible existence of cryptic phylogenetic species, remain poorly defined. Here, we use whole-genome sequence …
Market Integration And Price Transmission In The World Rice Export Markets, Bo Chen, Sayed H. Saghaian
Market Integration And Price Transmission In The World Rice Export Markets, Bo Chen, Sayed H. Saghaian
Agricultural Economics Faculty Publications
This paper investigates market integration and asymmetric price transmission in the world rice export markets. Using monthly rice prices from Thailand, Vietnam, and United States, we employ the Johansen test and estimate the threshold vector error correction model (TVECM). Our main findings are that export prices in the three countries are cointegrated, with Thailand and the United States the price leaders, and that the Vietnamese price adjusts faster to long-run equilibrium when it is above its equilibrium level with Thai and U.S. prices. These results suggest market integration and competition rather than collusion are prevalent in world rice markets. Policy …
