Available in PDF, EPUB and Kindle. Book excerpt: Canola (Brassica napus) oil has immense economic value due to its use as food. The production of biodiesel has led to the recent increase in the demand for canola oil, and further reinforced the need to improve the oil content and composition of canola seeds. The content and quality of canola oil is dependent on the process of fatty acid biosynthesis and accumulation of triacylglycerols (TAGs) during seed development. The biochemical pathways leading to the synthesis of fatty acids and TAGs are thoroughly understood, and many of the genes encoding the metabolic enzymes involved in this pathway have been isolated and functionally characterized. Despite comprehensive understanding of fatty acid and TAG biosynthesis, alternate factors and genes involved in the modification of seed oil content and composition are being investigated. This has initiated a new sector of research focusing on a series of transcription factors: LEAFY COTYLEDON1 (LEC1), LEAFY COTYLEDON2 (LEC2), FUSCA3 (FUS3) and WRINKLED1 (WRI1), which play a key role during embryo and seed development. Previous studies in Arabidopsis have demonstrated that the noted transcription factors influence the synthesis and accumulation of oil during seed development. These findings have prompted the design of two studies with the objective of further characterizing the role of these genes. In the first study, a homolog of Arabidopsis LEC1 was isolated from Brassica napus (Bn) microspore derived embryos. BnLEC1 contained the same distinct features identified in LEC1 genes from other plant species. BnLEC1 was inserted into an expression vector, which was subsequently used to transform Arabidopsis plants. The transgenic lines were characterized by differences in seed oil composition, and one line showed a reduction in the number of seeds counted per silique. Expression analysis revealed that the transgene was not expressed in the transgenic lines. To account for the discrepant findings, the possibility of endogenous gene silencing mechanisms suppressing transgene expression has been discussed. As an extension of this research, a second study assessed the differential expression of LEC1, LEC2, FUS3 and WRI1 in double haploid Brassica napus lines characterized by different levels of seed oil content. The expression level of the noted genes was determined at 7, 14, 21 and 28 days after pollination. Numerous changes in the transcript level were observed, but the trends were not consistent among high and low oil content lines.

Download or read book Regulation of Storage Oil Metabolism at the Transcriptional Level written by Ana T. Mendes and published by . This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: At the late stages of seed maturation, Arabidopsis thaliana seeds become filled with storage lipids. This source of energy is then used to support seed germination and seedling establishment. Although the metabolic pathways for synthesis and mobilisation of storage oil are well known, the regulation of these pathways remains more unclear. The aim of this project was to study the mechanisms of regulation of storage oil metabolism at the transcriptional level by identifying the transcriptional regulators and their target binding sequences in the promoters of genes involved in oil biosynthesis and breakdown in Arabidopsis seeds. A reverse genetic screen allowed the identification a transcription factor belonging to the bZIP family that is required for normal seed fatty acid composition. Seeds of the bzip67 mutant contain more linoleic (18:2) and less oleic (18:1) and linolenic (18:3) acid in their oil indicating that the desaturation process is compromised. Real-time PCR suggests that bZIP67 is a positive regulator of FATTY ACID DESATURASE 3 and a repressor of REDUCED OLEATE DESATUATION 1. Both genes are involved in fatty acid desaturation. Data from over-expression of bZIP67 also indicates that other partners are likely to be required to promote FAD3 gene expression. A different approach was taken to study the regulators of oil breakdown. Promoter analysis study of MALATE SYNTHASE (MLS) was carried out. MLS is a marker gene for the glyoxylate cycle, which allows the conversion of oil to sugar upon seed germination. Characterisation of T-DNA mutants disrupted in the MLS promoter suggests that the information required to drive MLS expression falls in the first ~140 bp of the promoter. The results show that this region is conserved in different Brassicales species and contains a number of conserved putative elements possibly required for MLS post-germinative expression. Different promoter-reporter constructs lacking each of the conserved elements were tested with a transient assay system using biolistics and the results indicate that putative ABI5, R1MYB, ABI4 and DOF binding elements are required for full MLS expression. Transcription factors from these families are therefore strong candidates as regulators of MLS expression.

Available in PDF, EPUB and Kindle. Book excerpt: A collection of papers that comprehensively describe the major areas of research on lipid metabolism of plants. State-of-the-art knowledge about research on fatty acid and glycerolipid biosynthesis, isoprenoid metabolism, membrane structure and organization, lipid oxidation and degradation, lipids as intracellular and extracellular messengers, lipids and environment, oil seeds and gene technology is reviewed. The different topics covered show that modern tools of plant cellular and molecular biology, as well as molecular genetics, have been recently used to characterize several key enzymes of plant lipid metabolism (in particular, desaturases, thioesterases, fatty acid synthetase) and to isolate corresponding cDNAs and genomic clones, allowing the use of genetic engineering methods to modify the composition of membranes or storage lipids. These findings open fascinating perspectives, both for establishing the roles of lipids in membrane function and intracellular signalling and for adapting the composition of seed oil to the industrial needs. This book will be a good reference source for research scientists, advanced students and industrialists wishing to follow the considerable progress made in recent years on plant lipid metabolism and to envision the new opportunities offered by genetic engineering for the development of novel oil seeds.

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.

Available in PDF, EPUB and Kindle. Book excerpt: This volume - the first of this series dealing with angiosperms - comprises the treatments of 73 families, representing three major blocks of the dicotyledons: magnoliids, centrosperms, and hamamelids. These blocks are generally recognized as subclasses in modern textbooks and works of reference. We consider them a convenient means for structuring the hundreds of di cotyledon families, but are far from taking them at face value for biological, let alone mono phyletic entities. Angiosperm taxa above the rank of family are little consolidated, as is easily seen when comparing various modern classifications. Genera and families, in contrast, are comparatively stable units -and they are important in practical terms. The genus is the taxon most frequently recognized as a distinct entity even by the layman, and generic names provide the key to all in formation available about plants. The family is, as a rule, homogeneous enough to conve niently summarize biological information, yet comprehensive enough to avoid excessive re dundance. The emphasis in this series is, therefore, primarily on families and genera.

This book was released on 2019-04-17 with total page 249 pages. Available in PDF, EPUB and Kindle. Book excerpt: With global populations expected to exceed 9.2 billion by 2050 and available land and water resources devoted to crop production dwindling, we face significant challenges to secure global food security. Only 12 plant species feed 80% of the world’s population, with just three crop species (wheat, rice and maize) accounting for food consumed by 50% of the global population. Annual losses to crop pests and pathogens are significant, thought to be equivalent to that required to feed a billion people, at a time when crop productivity has plateaued. With pesticide applications becoming increasingly unfeasible on cost, efficacy and environmental grounds, there is growing interest in exploiting plant resistance and tolerance traits for crop protection. Indeed, mankind has been selectively breeding plants for desirable traits for thousands of years. However, resistance and tolerance traits have not always been those most desired, and in many cases have been inadvertently lost during the domestication process: crops have been effectively ‘disarmed by domestication’. Moreover, mechanistic understanding of how resistance and tolerance traits operate is often incomplete, which makes identifying the right combination for crop protection difficult. We aimed to address this Research Topic by inviting authors to contribute their knowledge of appropriate resistance and tolerance traits, explore what is known about durability and breakdown of defensive traits and, finally, asking what are the prospects for exploiting these traits for crop protection. The research topic summarised in this book addresses some of the most important issues in the future sustainability of global crop production.

This book was released on 2008-04-15 with total page 392 pages. Available in PDF, EPUB and Kindle. Book excerpt: The formation, dispersal and germination of seeds are crucial stages in the life cycles of gymnosperm and angiosperm plants. The unique properties of seeds, particularly their tolerance to desiccation, their mobility, and their ability to schedule their germination to coincide with times when environmental conditions are favorable to their survival as seedlings, have no doubt contributed significantly to the success of seed-bearing plants. Humans are also dependent upon seeds, which constitute the majority of the world’s staple foods (e.g., cereals and legumes). Seeds are an excellent system for studying fundamental developmental processes in plant biology, as they develop from a single fertilized zygote into an embryo and endosperm, in association with the surrounding maternal tissues. As genetic and molecular approaches have become increasingly powerful tools for biological research, seeds have become an attractive system in which to study a wide array of metabolic processes and regulatory systems. Seed Development, Dormancy and Germination provides a comprehensive overview of seed biology from the point of view of the developmental and regulatory processes that are involved in the transition from a developing seed through dormancy and into germination and seedling growth. It examines the complexity of the environmental, physiological, molecular and genetic interactions that occur through the life cycle of seeds, along with the concepts and approaches used to analyze seed dormancy and germination behavior. It also identifies the current challenges and remaining questions for future research. The book is directed at plant developmental biologists, geneticists, plant breeders, seed biologists and graduate students.

Available in PDF, EPUB and Kindle. Book excerpt: During the past 15 years, cellular and molecular approaches have emerged as valuable adjuncts to supplement and complement conventional breeding methods for a wide variety of crop plants. Biotechnology increasingly plays a role in the creation, conservation, characterization and utilization of genetic variability for germplasm enhancement. For instance, anther/microspore culture, somaclonal variation, embryo culture and somatic hybridization are being exploited for obtaining incremental improvement in the existing cultivars. In addition, genes that confer insect- and disease-resistance, abiotic stress tolerance, herbicide tolerance and quality traits have been isolated and re-introduced into otherwise sensitive or susceptible species by a variety of transgenic techniques. Together these transformative methodologies grant access to a greater repertoire of genetic diversity as the gene(s) may come from viruses, bacteria, fungi, insects, animals, human beings, unrelated plants or even be artificially derived. Remarkable achievements have been made in the production, characterization, field evaluation and commercialization of transgenic crop varieties worldwide. Likewise, significant advances have been made towards increasing crop yields, improving nutritional quality, enabling crops to be raised under adverse conditions and developing resistance to pests and diseases for sustaining global food and nutritional security. The overarching purpose of this 3-volume work is to summarize the history of crop improvement from a technological perspective but to do so with a forward outlook on further advancement and adaptability to a changing world. Our carefully chosen “case studies of important plant crops” intend to serve a diverse spectrum of audience looking for the right tools to tackle complicated local and global issues.

Available in PDF, EPUB and Kindle. Book excerpt: Plants, unlike animals, are sessile. This demands that adverse changes in their environment are quickly recognized, distinguished and responded to with suitable reactions. Drought, heat, cold and salinity are among the major abiotic stresses that adversely affect plant growth and productivity. In general, abiotic stress often causes a series of morphological, physiological, biochemical and molecular changes that unfavorably affect plant growth, development and productivity. Drought, salinity, extreme temperatures (cold and heat) and oxidative stress are often interrelated; these conditions singularly or in combination induce cellular damage. To cope with abiotic stresses, of paramount significance is to understand plant responses to abiotic stresses that disturb the homeostatic equilibrium at cellular and molecular level in order to identify a common mechanism for multiple stress tolerance. This multi authored edited compilation attempts to put forth an all-inclusive biochemical and molecular picture in a systems approach wherein mechanism and adaptation aspects of abiotic stress are dealt with. The chief objective of the book hence is to deliver state of the art information for comprehending the effects of abiotic stress in plants at the cellular level.
