Book excerpt: Natural Rubber (NR) is an important strategic raw material for manufacturing a wide variety of industrial products. NR has been mainly obtained from Hevea brasiliensis. The USA is self-sufficient in the production of synthetic rubber while NR supply in USA is mainly imported from Southeast Asia. However, synthetic rubber cannot match the performance of imported Hevea NR. It is a matter of great concern that the USA is highly vulnerable to disruptions of NR supply because of a possible introduction of leaf blight into plantations as none of the trees in plantations across Southeast Asia have resistance to blight. Puskas et al. postulated that the biosynthesis of polyisoprenoids in general, and that of NR in particular, may proceed by a living carbocationic polymerization process. "Natural living carbocationic polymerization" (NLCP) mechanism was proposed in terms of accepted polymer chemical formalism, i.e., initiation, propagation, and equilibria between active and dormant species. This thesis studied the fundamental steps of NR biosynthesis in two ways: 1) characterization of NR from stabilized latex and in vitro biosynthesis; 2) addition of isoprene (IP) and other derivatives to shift the enzymatic equilibrium of the terpenoid biosynthesis lifecycle. Synthetic initiators to be used in in vitro NR biosynthesis system were prepared and characterized. For the first portion of this thesis, in vitro NR biosynthesis was studied using high resolution size exclusion chromatography (HR-SEC). Then, various compounds such as isoprene (IP) and amylene were introduced to the in vitro NR biosynthesis system. The rationale behind these studies was based on the terpenoid biosynthesis lifecycle. HRSEC, gravimetric analysis, in situ Raman spectroscopy and NMR spectroscopy were used to study scenarios where the equilibrium was disrupted by the introduction of foreign chemical compounds. The second goal of this research was to design and synthesize a synthetic initiator for the future synthesis in vitro of a novel polyisobutylene-block-cis-1,4-polyisoprene (PIB-b-NR) diblock copolymer. Two feasible synthetic pathways were developed to yield the target synthetic initiator: one by conventional syntheses and the other through an enzymatic pathway. The ultimate purpose of this synthetic initiator is to explore if the cis-prenyltransferase enzyme will recognize the compound and eventually apply this concept to novel terpenoids/NR in vitro. A seven-step synthetic strategy for the preparation of the PIB-NPP synthetic initiator is proposed and presented.

Book excerpt: This book presents the first comprehensive compilation of genome research on the Hevea brasiliensis rubber tree. The genomes of Hevea tree clones (cultivars) are described by three major international groups. Chapters on omics-driven investigations address a broad range of topics including genome annotation and utilisation, transcriptome and gene family analysis, genetic mapping, metabolic pathways in latex and molecular breeding. Additionally, an overview of fundamental rubber biology, especially on laticifers, provides a historical background that is relevant to rubber genome analysis. The book concludes with several perspectives on the future needs of rubber investigations and prospects of rubber genomics. Given the scope of topics, this book will appeal to researchers and university students working in genomics and biotechnology of the rubber tree, and to rubber breeders with an interest in non-conventional approaches to trait analysis, selection and breeding.

Available in PDF, EPUB and Kindle. Book excerpt: The importance of natural rubber is evident by the fact that it is a natural commodity that is necessary in the manufacturing of thousands of products. Natural rubber (cis -1,4-polyisoprene) is produced in a side branch of the isoprenoid mevalonate pathway, and in all rubber producing plants, it is synthesized in cytosolic vesicles known as rubber particles. Because the proteins that are involved are membrane bound, classic biochemical methods have failed to identify the exact proteins needed for rubber biosynthesis. The rubber transferase is a membrane bound enzyme responsible for elongation of the polymer molecule. Several proteins thought to be the rubber transferase, or proteins associated with the rubber particle membrane and thought to be involved in the rubber transferase complex have been assessed over the past 20 years, including the small rubber particle protein (SRPP). However, there has been a lack of in vivo evidence corroborating in vitro results that have suggested a function in rubber biosynthesis for most of these candidates. The aim of this study is to develop a system to functionally identify and characterize genes/proteins responsible for rubber biosynthesis. Taraxacum kok-saghyz, or Russian dandelion, provides a strong system to study rubber biosynthesis because it produces rubber of similar quality to Hevea brasiliensis, and it is amenable to transformation and greenhouse work and study. Several Russian dandelion SRPPs have been identified in a dandelion root cDNA library. Three of the five SRPPs were also tightly associated with dandelion rubber particles. Transgenic Russian dandelion lines were generated by over-expressing and knocking down the most abundant dandelion SRPP, TKS SRPP1. Results presented here show that SRPP not only influences rubber content in dandelion root, but also has an effect on rubber molecular weight. Broader impacts include using this knowledge to genetically engineer an ideal domestic source of natural rubber.

Available in PDF, EPUB and Kindle. Book excerpt: In the second edition of this book, the origin, upkeep and latex harvest from the Hevea rubber tree are dealt with succinctly. New chapters have been included on Propagation Systems and Genetic Resources. The importance of Heterozygosis and Breeding is a new theme for the section on Breeding. A new chapter on Genomics and Molecular Breeding that focuses on the latest advancements on gene mapping, marker assisted selection and stimulation has been added. Lastly, ‘textboxes’ that highlight points and topics of significant interest are included in the new addition. Natural rubber has been an essential commodity not only for the tire industry but also for more than 50,000 products that holds elasticity as an attribute. The prime source of natural rubber worldwide is Hevea brasiliensis. Hevea rubber tree is an excellent example of how a soil-tree-atmosphere system can work in tandem. The retrieval of rubber through ‘injuring’ the tree on alternate days or once in three days or once in seven days, is indeed a unique arrangement followed universally that ensures income to the planter almost throughout the year. Every molecule of rubber is the end result of meticulous biochemical changes. Therefore the biology of Hevea rubber tree itself is a subject that aggregates science and technology for the realization of its industrial utility.

This book was released on 2006 with total page 136 pages. Available in PDF, EPUB and Kindle. Book excerpt: "A detailed review of the biochemical literature concerning the biosynthesis of polyisoprenes, including natural rubber (NR, cis-1,4-polyisoprene cPIP) by rubber producing plants, and the polymer chemical literature on biomimetic and related syntheses, was made. It led us to postulate that the biosynthesis of polyisoprenoids in general, and that of NR in particular, may proceed by a living carbocationic polymerization process. Our analysis led to the formulation of a 'natural living carbocationic polymerization' (NLCP) mechanism in terms of accepted polymer chemical formalism, i.e., initiation, propagation, and equilibria between active and dormant species. A thorough analysis of the intermediates known to be involved in the biosynthesis of NR is consistent with our postulate. This review of the biochemical literature also inspired the concept of producing new block copolymers utilizing this process and a synthetic macroinitiator. A feasible synthetic pathway was developed to yield the target macroinitiator by combining conventional syntheses and natural rubber biosynthesis. This macroinitiator will consist of a polyisobutylene (PIB) chain carrying a neryl pyrophosphate functional group (PIBNPP) that will be synthesized from PIB-OH made by 'traditional' living carbocationic polymerization. The ultimate purpose is to explore if the cis-prenyltransferase enzyme involved in NR biosynthesis would recognize this new synthetic molecule as an initiator of cis-1,4-polyisoprene, such that this synthetic PIB-NPP macroinitiator would induce NR biosynthesis in vitro, and if so, could be used to produce PIB-b-NR block copolymer. A six-step synthetic strategy for the preparation of the PIB-NPP macroinitiator was proposed. The first three steps were successfully completed. The others were studied by carrying out experiments using model compounds, and the results obtained were extremely promising. In particular, a model molecule was successfully linked to the PIBOH starting material."--Abstract.

Available in PDF, EPUB and Kindle. Book excerpt: Plants produce a huge array of natural products (secondary metabolites). These compounds have important ecological functions, providing protection against attack by herbivores and microbes and serving as attractants for pollinators and seed-dispersing agents. They may also contribute to competition and invasiveness by suppressing the growth of neighboring plant species (a phenomenon known as allelopathy). Humans exploit natural products as sources of drugs, flavoring agents, fragrances and for a wide range of other applications. Rapid progress has been made in recent years in understanding natural product synthesis, regulation and function and the evolution of metabolic diversity. It is timely to bring this information together with contemporary advances in chemistry, plant biology, ecology, agronomy and human health to provide a comprehensive guide to plant-derived natural products. Plant-derived natural products: synthesis, function and application provides an informative and accessible overview of the different facets of the field, ranging from an introduction to the different classes of natural products through developments in natural product chemistry and biology to ecological interactions and the significance of plant-derived natural products for humans. In the final section of the book a series of chapters on new trends covers metabolic engineering, genome-wide approaches, the metabolic consequences of genetic modification, developments in traditional medicines and nutraceuticals, natural products as leads for drug discovery and novel non-food crops.
