The International Wheat Genetics Symposium (IWGS) is a one of the most important in wheat genetics and breeding science and is held every five years.Sponsoredby Kihara Institute for Biological Research£¬Yokohama City University, the 12th IWGS was held from September 8 to 14, 2013 in Yokohama, Japan. The symposium was attended by more than 300 delegates from the United States, Canada, Mexico, France, Germany, Italy, UK, Switzerland, China, India, Pakistan, Israel, Australia and other countries.There were 25 Chinese wheat experts and scholarsfrom Sichuan Province Academy of Agricultural Sciences, Shandong Academy of Agricultural Sciences,Shandong Agricultural University, Institute of Genetics and Physiology, Hebei Academy of Agriculture and Forestry Sciences, Institute of Genetics and Developmental Biology, Chinese Academy of sciences, and Institute of Crop Science, Chinese Academy of Agricultural Sciences attended the symposium. The 12th IWGScovered various topics includinggermplasm and genetic diversity, cytogenetics and evolution, genome sequencing, structural and functional genomics, gene function and molecular biology, biological and abiotic stress and quality and other major issues. A total of 74 experts delivered keynote reportsand 273posters were presented in the symposium.
The delegates exchanged research progressesininternational wheat genome, geneticand breeding in pastfive years, and discussed the future direction of development.International Wheat Genome Sequencing Consortium (IWGSC)reportedtheir experiences on hexaploid wheat sequencing, sequence assembly and analysis, progress of wheat chromosome 3B and 6B sequencing and its function to the sequence "survey" in the "wheat genome" research;ProfessorJia Jizeng described the further development and application of ancestral species in the wheat D genome after its sequencing in China. In the "germplasm resources and genetic diversity" sectionand "assessments of wheat genetic resources collection" section, experts presented theapproaches to collectand preserve wild species in different regions and types of modern breeding, and discussedthe future application of these germplasm resources toimprove wheat yield and adaptability; ProfessorZhang Xueyong presented theie research progress on wheat core germplasm development and exploration of important agronomic trait genes from them.In "structure and functionalgenomics" issue, Dr. Rohit Mago from Australia introduced their work in stem rust gene Sr2 haplotypes and functions;Dr. Graham Moore from UK described the research historyof chromosome pairing gene Ph1, Yan Liuling from the United States explained the genetic mechanismsabout the needs of winter wheat vernalization. In the "biotic and abiotic stress" issue, experts had anactivediscussion on excavations, genetic mechanisms, breeding methods and strategies of new resistant genes/QTLs.
It is at a critical timefor rapid development of wheat genomeand related research. By attending the symposium, the attendees can master the research trend and exchange research experiences, which should promote wheat genome, molecular breeding, germplasm resources, and other relevant researches in China.
