This book was released on 2018 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Canola (oilseed rape, Brassica napus L.) is a cash crop grown in different countries including Canada, the European Union, China and Australia. The production of this crop is threatened by blackleg disease caused by the fungus Leptosphaeria maculans (Desm.) Ces. & De Not. [anamorph: phoma-like (de Gruyter)]. In order to develop a more effective disease management strategy; there is a need to employ crop rotation, introgress new resistance (R) genes into elite cultivars, test the effectiveness of existing R genes, and predict the emergence of virulent isolates of L. maculans. In this study, sequenced characterised amplified region (SCAR) and derived-cleaved amplified polymorphic sequence (dCAPS) markers linked to the L. maculans resistance gene Rlm6 were developed and their segregation was confirmed by analysis of F2 and F3 progeny. In addition, chromosomal segment substitution lines (CSSLs) harbouring Rlm6 were developed through a combined approach of classical and marker-assisted backcross breeding. The field study suggested a potential effectiveness of a 2-year crop rotation, because of the reduction of disease severity at the end of the 4-year trial. By the end of the study, the R genes LepR1, LepR3, Rlm2, and Rlm4 were effective against L. maculans, whereas Rlm3 was moderately effective. Linear regression analysis suggests an order of effectiveness among the R genes tested: LepR3 > LepR1> Rlm2 > Rlm4 > Rlm3. Moreover, the decreased frequency of effector genes AvrLm2 and AvrLm4 in L. maculans isolates suggested the gaining of virulence toward Rlm2 and Rlm4 within a year. Results from sequencing of the AvrLm2 gene revealed a shift of AvrLm2 to avrLm2 allele due to the accumulation of point mutations. Overall, CSSLs and DNA markers developed in this study may facilitate breeding B. napus varieties resistant to L. maculans in the future. It is predicted that rotation of Rlm2, Rlm3, Rlm4, and Rlm7 could be an opportunity to increase the effectiveness of those R genes under a 2-year crop rotation. However, these studies also suggest development of generic epidemiological models for the occurrence of complex molecular interactions in B. napus-L. maculans pathosystem, allowing plant breeders to select appropriate R genes in the proposed cultivar rotation strategies on the Prairies.
Download or read book Biotrophic Plant Microbe Interactions written by Pietro D. Spanu and published by Frontiers Media SA. This book was released on 2017-04-20 with total page 433 pages. Available in PDF, EPUB and Kindle. Book excerpt: Throughout their life, plants interact with all sorts of microbes. Some of these are detrimental and cause disease; some interactions are mutually beneficial for both partners. It is clear that most, if not all, of the interactions are regulated by highly complex checks and balances sustained by signalling and exchange of messengers and nutrients. The interactions where both partners are alive for a significant part of their time together are called biotrophic. In this e-book we bring together 33 articles representing the current state-of-the-art in research about diverse biotrophic plant-microbe associations aimed at describing and understanding how these complex and ubiquitous partnerships work and ultimately support much of the land-based biosphere.

Download or read book Plant Breeding from Laboratories to Fields written by Sven Bode Andersen and published by BoD – Books on Demand. This book was released on 2013-05-22 with total page 302 pages. Available in PDF, EPUB and Kindle. Book excerpt: Breeding of crop plants to make them more adapted to human agricultural systems has been on-going during domestication the last 10 000 years. However, only recently with the invention of the Mendelian principles of genetics and the subsequent development of quantitative genetics during the twentieth century has such genetic crop improvement become based on a general theory. During the last 50 years plant breeding has entered a molecular era based on molecular tools to analyse DNA, RNA and proteins and associate such molecular results with plant phenotype. These marker trait associations develop fast to enable more efficient breeding. However, they still leave a major part of breeding to be performed through selection of phenotypes using quantitative genetic tools. The ten chapters of this book illustrate this development.
Download or read book Biocontrol Based Integrated Management of Oilseed Rape Pests written by Ingrid H. Williams and published by Springer Science & Business Media. This book was released on 2010-06-16 with total page 461 pages. Available in PDF, EPUB and Kindle. Book excerpt: Oilseed rape is a major arable crop in both Europe and North America. It is attacked by unique complexes of insect pests still largely controlled through the application of chemical insecticides. Crop management systems for the future must combine sustainability with environmental acceptability to satisfy both social and economic demands. This book, in its 17 chapters each led by a world expert, reviews research progress towards developing integrated pest management systems for the crop that enhance conservation biocontrol. This approach is particularly timely because of the development in Europe of insecticide resistance in the pollen beetle, a major pest of the crop. The past decade has seen considerable progress in our knowledge of the parasitoids and predators that contribute to biocontrol, of their distribution patterns, and their behavioural ecology, both within and without the crop. There is potential for natural enemy conservation through modification of within-field crop husbandry practices, as well as, on the landscape scale, through habitat manipulation to encourage vegetational diversity. This book will prove invaluable as a text for researchers, university teachers, graduate scientists, extension workers and growers involved in integrated pest management.

Available in PDF, EPUB and Kindle. Book excerpt: When one is privileged to participate long enough in a professional capacity, certain trends may be observed in the dynamics of how challenges are met or how problems are solved. Agricultural research is no exception in view of how the plant sciences have moved forward in the past 30 years. For example, the once grand but now nearly forgotten art of whole plant physiology has given way almost completely to the more sophisticated realm of molecular biology. What once was the American Society of Plant Physiologists’ is now the American Society of Plant Molecular Biology; a democratic decision to indemnify efforts to go beyond the limits of the classical science and actually begin to understand the underlying biological basis for genetic regulation of metabolic mechanisms in plants. Yet, as new technologies open windows of light on the inner workings of biological processes, one might reminisce with faint nostalgia on days long past when the artisans of plant physiology, biochemistry, analytical chemistry and other scientific disciplines ebbed and waned in prominence. No intentional reference is made here regarding Darwinism; the plant sciences always have been extremely competitive. Technology is pivotal. Those who develop and/or implement innovative concepts typically are regarded as leaders in their respective fields. Each positive incremental step helps bring recognition and the impetus to push a scientific discipline forward with timely approaches to address relevant opportunities.
