This book was released on 2011 with total page 185 pages. Available in PDF, EPUB and Kindle. Book excerpt: Downy mildew, caused by P. halstedii, is one of the major diseases for sunflower (Helianthus annuus). Pl genes conferring full, qualitative resistance were discovered and extensively spread in cultivars. They appeared as race-specific and were progressively overcome due to the selection pressure on the pathogen. Thus since 10 years we are witnessing an increase of P. halstedii races in the fields. Quantitative resistance was found by Tourvieille et al. (2008) and proposed as a solution to counter the rapid evolution of the pathogen. Two QTLs were detected at LG10 and LG8 in a RIL population from XRQ*PSC8 by Vear et al. (2008). With the aim to improve the sustainability of sunflower resistance in gathering knowledge on several aspects of the plant*pathogen interaction, the objectives of this thesis are (i) on the pathogen side, to better characterize P. halstedii at the genetic and genomic level, (ii) on the plant side, to obtain a fine mapping of the main QTL located on LG10 (QRM1) and (iii) to compare the Pl5 gene and QRM1-R dependent genetic pathways by transcriptomic analysis. The first high-throughput sequencing was performed on infected sunflower which increased the available genomic resources of P. halstedii and highlighted first putative effectors RXLR and CRN of P. halstedii. On the plant side, we performed a fine mapping of QRM1: a new BAC library was built and screened to set up a preliminary physical map of the QRM1 region; genetic map of LG10 was enriched with BAC derived markers and a phenotyping method to mimic the quantitative resistance in controlled environment was validated and used to phenotype newly constructed RILs. The QRM1 region was restricted to 1.5 cM. Using Sunflower Affymetrix chip, transcriptomic analysis revealed different genetic pathways depending on incompatible interaction (Pl5 gene * race 710) or quantitative interaction managed by QRM1-R.

Download or read book Marker Development, Genome Mapping, and Cloning of Candidate Disease Resistance Genes in Sunflower, Helianthus Annuus L written by Melaku Ayele Gedil and published by . This book was released on 1999 with total page 238 pages. Available in PDF, EPUB and Kindle. Book excerpt: The level of polymorphisms of many biochemical and DNA markers are low in cultivated sunflower (Helianthus annuus L.). The number of mapped public DNA markers is limited. Molecular markers have not been developed for the most important diseases of sunflower, such as downy mildew. The objectives of this study were (i) to help alleviate the problem of low DNA marker polymorphisms by developing simple sequence repeat (SSR) markers, (ii) to build an integrated AFLP-RFLP linkage map by using previously described probes and newly developed AFLPs, and (iii) to clone and characterize candidate disease resistance genes. Forty-four polymorphic SSR markers were developed from a genomic DNA library. Diversity analysis of these SSRs for variability among 10 public inbred lines produced an average of 1.86 alleles per locus and mean heterozygosity of 0.21. The number of alleles ranged from 1 to 5. Trinucleotide SSRs were less polymorphic than dinucleotide and mononucleotide SSRs. Cluster analysis and multidimensional scaling separated elite inbred lines from wild species. There was more polymorphism in wild species than in elite lines. Three hundred and six AFLP markers were developed using 18 primer combinations. Two sets of previously mapped RFLP markers were tested for segregation in an F2 mapping population. A total of 401 markers were assigned to 17 linkage groups covering 1326 cM with a mean spacing of 3.3 cM between adjacent markers. The RFLP markers were well spaced and well distributed throughout the genome. Some linkage groups are sparsely populated with common markers. There were two gaps of 30 or more cM in two linkage groups. We cloned candidate disease resistance genes for downy mildew resistance based on sequence homology among resistance genes in other species. Eleven unique nucleotide binding sequence (NBS) containing clones were isolated and showed similarity to the corresponding domains of cloned disease resistance genes in other plant species. Seven clones mapped to four linkage groups and identified nine loci. A cleaved amplified polymorphic sequence (CAPS) marker that was 3.7 cM from the Pl1 resistance gene was developed by analysis of NILs. This CAPS marker should facilitate marker-assisted selection in sunflower.

Book excerpt: This book presents a broad number of recent discoveries, advances and important results concerning sunflower (Helianthus annus) crops and its related fields, with emphasis on the detailed study of several diseases and pests that can affect sunflowers (production, water resources needed, economy impact) in different regions of the globe, including Russia, both North and South America, Africa, India and Europe. We are all well aware of the increasing importance, as well as the economic impact that these plants have reached in recent years, not only in the food industry but also in the western energy market, with the increasing use of sunflower oil as a natural energy resource for biodiesel and biofuel. Apart from the interesting recent advances, results and conclusions presented in every chapter, plenty of visual and graphical content comprised of tables, charts, graphs, pictures and high quality detailed photographs and images showing different issues and problems regarding sunflower crops are also included. The manuscript chapters have been authored by experts in the field and in addition all of them underwent a stringent peer review process by expert reviewers to assure a high final scientific quality.
