This book was released on 2013 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Root-lesion nematodes (RLN) Pratylenchus thornei Sher and Allen, 1953 and P. neglectus (Rensch, 1924) Filipjev Schuurmans and Stekhoven are soil-borne pathogens of wheat that invade and feed on root host cells. In the Pacific Northwest (PNW) these species of nematode were found in 95% of sampled fields and were estimated to cause 37% - 50% yield loss in spring wheat. Resistance to P. thornei had previously been found in 78 Iranian landrace accessions. The accessions were tested for resistance to P. neglectus and 21 accessions were found to be resistant to both species. The dual-resistant landrace accession, AUS28451 (PI623470), was used to generate a recombinant inbred line (RIL) population by crossing it to the susceptible PNW cultivar, Louise. One-hundred and fifty F2:F6 derived RILs were genotyped using SSR and SNP based molecular markers. The RILs were then phenotyped using inoculated field soil greenhouse assays where nematodes counted at the end of a 12 week period. A new root rating method to determine nematode resistance was also developed and tested in the greenhouse assays. Resistance associated quantitative trait loci (QTL) were identified on chromosomes 1A, 2B, 4A, 5A, 5B, 6B and 7A using both phenotyping methods for P. thornei and P. neglectus. Canopy temperature and photosynthesis yield (phiPSII) were used to develop a prediction model for nematode population densities on resistant and susceptible cultivars planted in infested fields. The RIL population was used to verify the accuracy of the prediction model. Predicted nematode resistance associated QTL were identified on chromosomes 4A, 5A, 6A, 6B, and 6D. Root morphology observations suggested AUS28451 (PI623470) had increased root lignin content compared to Louise. Root lignin content was examined in the RIL population and associated QTL were identified on chromosomes 2D and 5B. With this research, three new methods for indirect Pratylenchus resistance screening have been developed. These methods include molecular markers associated with resistance, root ratings, and field stress measurements. With these methods breeders will be able to incorporate nematode resistance breeding into their programs using a variety of tools.
Book Synopsis Genetic and Biological Characterisation of Resistance to Root Lesion Nematode Pratylenchus Thornei in Wheat by : Katherine Joanne Linsell
Download or read book Genetic and Biological Characterisation of Resistance to Root Lesion Nematode Pratylenchus Thornei in Wheat written by Katherine Joanne Linsell and published by . This book was released on 2013 with total page 352 pages. Available in PDF, EPUB and Kindle. Book excerpt: Root lesion nematodes of the genus Pratylenchus feed and reproduce in the root cortex of many plant species, including wheat. Migration through root tissue causes extensive root damage, and in turn severe reductions in growth and yield. In Australia, one of the most prevalent and widespread species affecting wheat is Pratylenchus thornei. Due to the wide host range of Pratylenchus spp. and the restrictions and inefficiency of chemical pesticides, the development of resistant cultivars has become increasingly important. Despite the identification and investigation of several resistance sources and resistance quantitative trait loci (QTL), no P. thornei resistance has been integrated into commercial cultivars. In addition, prior to this study, the biological resistance mechanisms of wheat against P. thornei were not well characterised. The identification of novel sources of genetic resistance in wheat and understanding of the biological mechanisms will allow effective combinations of genes either to be used alternatively or pyramided to generate effective and stable Pratylenchus resistance. The major objectives of the study were to identify genetic loci associated with P. thornei resistance and to investigate the associated biological mechanisms in a double haploid wheat population developed from a cross between the synthetically derived Sokoll and the Australian adapted Krichauff parental lines.

Book Synopsis Nematode Interactions by : M. Wajid Khan
Download or read book Nematode Interactions written by M. Wajid Khan and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 388 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nematode interactions are important biological phenomena and of great significance in agriculture. It is a fascinating subject which is multidisciplinary by nature, and concerns any scientist involved with plant health. There have been marked advances in our knowledge of various aspects of the subject in the last two decades. This study area has been the subject of several reviews, but there was no exclusive text on the subject. This has stressed the need to document the information, developing a unifying theme which treated nematode interactions in a holistic manner. This book is about the inter action of plant-parasitic nematodes with other plant pathogens or root symbionts, the nature of their associations, their impact on the host and con sequential interactive effects on the involved organisms. Since nematodes are at the centre of the theme, the responsibility of understanding of other plant pathogens dealt with in this book is largely delegated to the reader. I have limited the book content to interactions with biotic pathogens and root symbionts only, for various reasons. The book embodies 16 chapters, and attempts to present balanced infor mation on various aspects of nematode interactions with other plant pathogens and root symbionts. Some chapters describe general aspects of the subject. Interactions of nematodes with specific groups of organisms are addressed in the remaining chapters.

This book was released on 1997 with total page 306 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1992 a Concerted Action Programme (CAP) was initiated by Peter Sijmons with the purpose of intensifying collaborations between 16 European laboratories working on plant-parasitic nematodes. The four-year programme entitled Resistance Mechanisms Against Plant-Parasitic Nematodes focused on molecular aspects of the interaction between sedentary nematodes and plants on the model system Arabidopsis and on novel resistance strategies. Funding was provided mainly for exchange visits between collaborating laboratories and for the organization of annual meetings. During the last annual meeting which was held in May 1996 in Toledo, Spain, Carmen Fenoll initiated the production of this volume.

Book Synopsis Plant Nematology, 3rd Edition by : Roland N. Perry
Download or read book Plant Nematology, 3rd Edition written by Roland N. Perry and published by CABI. This book was released on 2024-07-12 with total page 661 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plant-parasitic nematodes are a major threat to crop production in all countries, and identification of nematodes and knowledge of their biology is of paramount importance. Providing a broad introduction to nematodes as plant parasites, this book begins by describing nematodes by genera, and then builds on this foundation to detail nematode biology and pest management, including resistance, and biological and chemical control. This 3rd edition is updated to address advances in our knowledge of plant-parasitic nematodes, particularly concerning the molecular aspects of host-parasite relationships, including the application of genomics to nematode biology. Changes in control and management strategies are also covered. The influence of climate change on plant-parasitic nematodes is addressed in a new chapter on ecology. Primarily aimed at students (MSc and PhD), this book is also invaluable for researchers and lecturers in nematology, plant pathology and parasitology, advisory and quarantine services, and crop protection scientists.
