The damage to the plants is in the form of infections on seed in the soil during sowing, on seedlings during emergence and growth, on stem, leaves, inflorescence, pods and finally to the seed causing yield losses in seed quantity and quality.
Download or read book Current Trends in Plant Disease Diagnostics and Management Practices written by Pradeep Kumar and published by Springer. This book was released on 2016-04-28 with total page 471 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plant diseases play an important role on our daily lives. Most of plant diseases are visible and are caused by biotic and/or abiotic factors. Symptoms are usually the results of a morphological change, alteration or damage to plant tissue and/or cells due to an interference of the plant’s metabolism. All basic structures of vascular plants are subject to attack by pathogens. The failure in accurate disease diagnosis and management may lead to huge losses in plant production and related commodities, which causes nutritional food scarcity. Typically, the appearance of a biotic symptom will indicate the relatively late stage of an infection and/or colonization of a pathogen. Expert detection, accurate diagnosis, and timely management play a significant role in keeping plants free from pathogens. In this book expert scholars share their research knowledge and key literature which are vital toward the diagnosis of plant diseases across the globe, addressing traditional plant pathology techniques, as well as advanced molecular diagnostic approach.

Available in PDF, EPUB and Kindle. Book excerpt: Global population is mounting at an alarming stride to surpass 9.3 billion by 2050, whereas simultaneously the agricultural productivity is gravely affected by climate changes resulting in increased biotic and abiotic stresses. The genus Brassica belongs to the mustard family whose members are known as cruciferous vegetables, cabbages or mustard plants. Rapeseed-mustard is world’s third most important source of edible oil after soybean and oil palm. It has worldwide acceptance owing to its rare combination of health promoting factors. It has very low levels of saturated fatty acids which make it the healthiest edible oil that is commonly available. Apart from this, it is rich in antioxidants by virtue of tocopherols and phytosterols presence in the oil. The high omega 3 content reduces the risk of atherosclerosis/heart attack. Conventional breeding methods have met with limited success in Brassica because yield and stress resilience are polygenic traits and are greatly influenced by environment. Therefore, it is imperative to accelerate the efforts to unravel the biochemical, physiological and molecular mechanisms underlying yield, quality and tolerance towards biotic and abiotic stresses in Brassica. To exploit its fullest potential, systematic efforts are needed to unlock the genetic information for new germplasms that tolerate initial and terminal state heat coupled with moisture stress. For instance, wild relatives may be exploited in developing introgressed and resynthesized lines with desirable attributes. Exploitation of heterosis is another important area which can be achieved by introducing transgenics to raise stable CMS lines. Doubled haploid breeding and marker assisted selection should be employed along with conventional breeding. Breeding programmes aim at enhancing resource use efficiency, especially nutrient and water as well as adoption to aberrant environmental changes should also be considered. Biotechnological interventions are essential for altering the biosynthetic pathways for developing high oleic and low linolenic lines. Accordingly, tools such as microspore and ovule culture, embryo rescue, isolation of trait specific genes especially for aphid, Sclerotinia and alternaria blight resistance, etc. along with identification of potential lines based on genetic diversity can assist ongoing breeding programmes. In this book, we highlight the recent molecular, genetic and genomic interventions made to achieve crop improvement in terms of yield increase, quality and stress tolerance in Brassica, with a special emphasis in Rapeseed-mustard.

Available in PDF, EPUB and Kindle. Book excerpt: The family Brassicaceae constitutes one of the world’s most economically important plant groups. These plants are important sources of vegetable oil, vegetables, and condiments. Most of these crops belong to the genus Brassica, which includes common crops such as oilseeds (oilseed rape, mustard) and vegetables (broccoli, cauliflower, brussels sprouts, cabbage, turnip, Chinese cabbage, etc.). Brassica species play an essential role in horticulture and agriculture as well as contribute to the health of populations around the world. The current global climatic model predicts a significant decrease in growth, yield, and productivity of Brassica due to various biotic and abiotic stress factors. Thus, high-yielding, climate-resilient, and disease-resistant Brassica varieties are required to maintain as well as increase future agricultural production. The development of improved cultivars of these crops may become exhausted and improvement could become stagnant when plant breeding is merely based on a single breeding approach. Therefore, the goal of a breeding program should be to develop genetically superior Brassica cultivars suitable for a wide range of environments. This book examines the introgression of insect and disease resistance and other desirable traits into Brassica crops using inter-and/or intra-specific hybridization as well as biotechnological and molecular techniques, which could be useful for improving Brassica crops to ensure food security.
Download or read book Agrobacterium mediated Transformation of Brassica Oleracea Var Italica and B Napus with a Trichoderma Harzianum Endochitinase Gene to Enhance Resistance Against Fungal Pathogens written by Alejandra Mora-Avilʹes and published by . This book was released on 2000 with total page 474 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The control of pathogens in food crops is a general concern around the world. Much effort has been devoted to the control of fungal pathogens, mainly by pesticide application, cultural practices, biocontrol, or traditional plant breeding. Limited sources of resistance among cultivated plants or their wild relatives have made it important to look for alternative resistance genes and transfer techniques. This dissertation addresses the introduction of a Trichoderma. harzianum endochitinase gene into Brassica oleracea and B. napus by Agrobacterium tumefaciens-mediated transformation, and the molecular analysis and fungal resistance of the transgenic plants. The T. harzianum endochitinase has been reported to have fungal inhibiting properties in assays performed in vitro. Recently, transgenic crops such as potato, tomato, tobacco, apple, and grape expressing the endochitinase gene have been analyzed to assess their protection against fungal pathogens, with variable results. Chapter I reviews previous reports of chitinase genes from plants and microorganisms used in plant transformation. It describes the levels of expression of chitinase in various transgenic plants and the levels of control of fungal pathogens. Chapter I also discusses previous work on Agrobacterium-mediated transformation of Brassica oleracea. Chapter II presents experiments testing some of the factors that affect the efficiency of Agrobacterium-mediated transformation of broccoli. Chapter III focuses on molecular aspects of gene expression of transgenic broccoli and rapeseed plants containing the T. harzianum endochitinase gene and describes pathogenic assays to assess the resistance of the transgenic plants to the fungal pathogens Alternaria brassicicola and Sclerotinia sclerotiorum. Chapter IV discusses the interaction of endochitinase and the fungicide Bayleton for the control of A. brassicicola. Finally, Chapter V addresses the induction of pathogenesis-related proteins by constitutive expression of the endochitinase gene"--Leaves xv-xvi

Download or read book Trends and Perspectives for the Use of Crop Wild Relatives in Crop Breeding written by Mahesh Rao and published by Frontiers Media SA. This book was released on 2024-05-28 with total page 197 pages. Available in PDF, EPUB and Kindle. Book excerpt: Crop Wild Relatives (CWRs) are a key asset for agrobiodiversity, sustainable agriculture and food security overall. CRWs might contain genes for useful traits such as nutritional quality, resistance to pests and diseases, resource efficiency, and adaptability to extreme weather conditions. Their inherent genetic diversity together with the associated diversity of microbiota is a vast resource for developing more productive, nutritious, and resilient crop varieties and for diversifying farming systems. Despite their value, a wide range of CWRs are threatened and face pressures, e.g., from intensive agriculture, urbanization, pollution, and the effects of climate change. At the same time, their conservation and deployment in breeding remain still scarce. As a consequence, knowledge is lacking about the diversity that exists and precisely how that diversity may be used for crop improvement and in farming.
