Book excerpt: Wheat leaf rust, stem rust, and stripe rust are major fungal diseases of wheat caused by Puccinia triticina, P. graminis f. sp. tritici, and P. striiformis f. sp. tritici, respectively. Development of wheat varieties with genetic resistance to pathogens is a common strategy to protect against significant yield loss. However, incorporating resistance is not always straightforward, and understanding the mechanisms responsible for triggering host resistance is key. Here, were characterized two different genetic mechanisms involved in the rust resistance defense response in wheat. Two spring wheat cultivars and their respective EMS mutants, which displayed enhanced resistance to leaf, stem, and/or stripe rust, were studied. The cultivar Canthatch possesses a stem rust resistance suppressor on chromosome 7DL. We characterized the spectrum of resistance of Canthatch and the mutant CTH-NS, confirming the specificity of this suppressor is stem rust-specific. The cultivar Alpowa mutant MNR220 displays broad-spectrum resistance to a number of wheat rust races at the seedling stage. We characterized the functional resistance of MNR220 to a race of leaf rust by sampling inoculated tissues at various time points and tracking the disease progress microscopically. The mutant MNR220 confers resistance at the pre-haustorial stage; formation of haustoria is delayed or inhibited in MNR220 relative to the wild type Alpowa.

This book was released on 2014 with total page 266 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wheat is one the most important food crops in the world, grown on more acreage than any other. Puccinia graminis f. sp. tritici, the causal agent of wheat and barley stem rust, is responsible for major production losses around the world. The development of resistant cultivars is an effective way to manage the disease, but outbreaks can occur when new pathogen races overcome the existing resistances. This happened with Ug99 (TTKSK), a highly virulent race now spreading in Africa and the Middle East and dangerously threatening worldwide food security. Thus, constant efforts to find new sources of resistance must remain a priority. The hexaploid wheat cultivar Canthatch has long been known for carrying a suppressor of stem rust resistance on chromosome 7DL. This suppressor is now of particular interest, as the genes it inhibits were found to be strongly effective against Ug99. Because the 7DL suppressor seems to be common in wheat cultivars, cloning it would be the first step toward unlocking the masked resistance genes, as well as providing new information about the nature of action of a previously unstudied class of negative regulators of plant defence responses. This study first aimed to genetically map the 7DL suppressor. A F2:3 mapping population was developed from the cross between the susceptible line Columbus, thought to possess the 7DL suppressor, with the resistant line Columbus-NS, a near-isogenic line in which a mutated allele of the suppressor was inferred to have been transferred into the Columbus genetic background. The mapping population was phenotyped using two stem rust races, Ug99 and #313, for which results were similar, indicating a common resistance against both races. Molecular markers were found using two recently developed techniques: i) genotyping of nearly 9,000 putative single nucleotide polymorphisms (SNP) using the wheat 9k SNP chip and ii) genotyping by sequencing using the restriction-site associated DNA sequencing (RAD-Seq) method in association with bulked segregant analysis. This led to the rapid identification of thousands of markers putatively linked to the stem rust resistance in Columbus-NS. Surprisingly, genetic mapping revealed the resistance to be located on 7AL, not 7DL, indicating that it was due to a new resistance locus rather than a non-suppressor. This locus is most likely part of the resistance complex repressed by the 7DL suppressor. Although segregation ratios in the F2:3 population indicated monogenic segregation (1:2:1), phenotypic observations and genomic studies indicated the possible involvement of multiple genes in the resistance, notably on chromosome 6A. The 7AL locus seemed to be essential but not sufficient for full resistance. The resistance response was also investigated at a microscopic level, which showed the involvement of cell death during the rust penetration through the stoma, at two days post-inoculation. Transcriptome analysis using RNA-Seq revealed 353 genes differentially expressed between Columbus and two independent Columbus-NS lines. Notably, several genes coding for cysteine-rich receptor-like kinases were found to be good candidates for involvement in the defence response.

Available in PDF, EPUB and Kindle. Book excerpt: This proceedings is a collection of 46 selected papers that were presented at the 12th International Wheat Genetics Symposium (IWGS). Since the launch of the wheat genome sequencing project in 2005, the arrival of draft genome sequences has marked a new era in wheat genetics and genomics, catalyzing rapid advancement in the field. This book provides a comprehensive review of the forefront of wheat research, across various important topics such as germplasm and genetic diversity, cytogenetics and allopolyploid evolution, genome sequencing, structural and functional genomics, gene function and molecular biology, biotic stress, abiotic stress, grain quality, and classical and molecular breeding. Following an introduction, 9 parts of the book are dedicated to each of these topics. A final, 11th part entitled “Toward Sustainable Wheat Production” contains 7 excellent papers that were presented in the 12th IWGS Special Session supported by the OECD. With rapid population growth and radical climate changes, the world faces a global food crisis and is in need of another Green Revolution to boost yields of wheat and other widely grown staple crops. Although this book focuses on wheat, many of the newly developed techniques and results presented here can be applied to other plant species with large and complex genomes. As such, this volume is highly recommended for all students and researchers in wheat sciences and related plant sciences and for those who are interested in stable food production and food security.

Book excerpt: Based on sequence analyses of many different genes, the past decade has provided us with a profound knowledge of fungal systematics and phylogeny. In addition, a number of sequences of complete fungal genomes have been identified and several others will soon follow. In this volume, leading experts address questions concerning the origin of the fungal kingdom and fungal evolution at a level of analytical refinement that has never been possible before. The following major aspects are highlighted: evolutionary roots of fungi; evolution of signaling in fungi and fungal-like organisms; evolution of mutualistic systems and metabolism in fungi; and evolutionary mechanisms and trends.
