This book was released on 2012-03-14 with total page 394 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bacillus thuringiensis (Bt) has been used as a biopesticide in agriculture, forestry and mosquito control because of its advantages of specific toxicity against target insects, lack of polluting residues and safety to non-target organisms. The insecticidal properties of this bacterium are due to insecticidal proteins produced during sporulation. Despite these ecological benefits, the use of Bt biopesticides has lagged behind the synthetic chemicals. Genetic improvement of Bt natural strains, in particular Bt recombination, offers a promising means of improving efficacy and cost-effectiveness of Bt-based bioinsecticide products to develop new biotechnological applications. On the other hand, the different Bacillus species have important biotechnological applications; one of them is carried out by producing secondary metabolites, which are the study object of natural product chemistry. The amazing structural variability of these compounds has attracted the curiosity of chemists and the biological activities possessed by natural products have inspired the pharmaceutical industry to search for lead structures in microbial extracts. Screening of microbial extracts reveals the large structural diversity of natural compounds with broad biological activities, such as antimicrobial, antiviral, immunosuppressive, and antitumor activities that enable the bacterium to survive in its natural environment. These findings widen the target range of Bacillus spp., in special B. thuringiensis, besides insecticidal activity and help people to better understand its role in soil ecosystem.

Chapter One concerns the use of biopesticides in sustainable agriculture, including the interactions between biopesticides and chemical pesticides, production issues, and opportunities for future research. Chapter Two describes the bottom-up approach for using Bacillus thuringiensis (Bt) as a biopesticide and for enhancing host plant resistance against major foliage feeders through deployment of suitable cry genes. Chapter Three reviews strategies for mitigating the spread of Bt resistance and improving insecticidal activity against Bt-susceptible pests. Lastly, Chapter Four aims to revise, debate, and evaluate the effects of Bt as phosphate solubilizing and phosphorus uptake by plant establishment"--

Download or read book Microbial Megaplasmids written by Edward Schwartz and published by Springer Science & Business Media. This book was released on 2009-01-29 with total page 348 pages. Available in PDF, EPUB and Kindle. Book excerpt: Megaplasmids are extrachromosomal genetic elements in the size range of 100 kb and larger. They are found in physiologically and phylogenetically diverse groups of bacteria and archaea. By definition, megaplasmids are not essential for the viability of their hosts under all growth conditions, but paradoxically many megaplasmids carry the genetic information for the defining and characteristic traits of the organism in which they reside. Microbial Megaplasmids reviews our knowledge of the extensively studied representatives, such as the catabolic plasmids of the pseudomonads, the rhizobial Sym plasmids, the Ti plasmids of the genus Agrobacterium and the giant enterobacterial virulence plasmids. It also presents snapshots of more recently discovered megaplasmids. The contribution of megaplasmids to the biology of their hosts is described, highlighting the interactions between megaplasmid and chromosomal genes.

Download or read book Phyto Microbiome in Stress Regulation written by Manoj Kumar and published by Springer Nature. This book was released on 2020-03-16 with total page 346 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book addresses “phyto-microbiome mediated stress regulation”. Fundamentally speaking, the microbial community’s importance for the survival of plants under stress conditions has already been confirmed. This book focuses on the roles of those rhizospheric microbiomes that are advantageous to plant developmental pathways. Gathering contributions by authors with specialized expertise in plant growth and health under stress conditions, as well as opportunistic pathogenic bacteria, the book reviews the functional aspects of rhizospheric microorganisms and how they impact plant health and disease. It offers a compendium of plant and microbial interactions at the level of multitrophic interactions, and identifies gaps between future demand and present research on plant stress. In closing, the authors highlight several directions for reshaping rhizosphere microbiomes in favor of microorganisms that are beneficial to plant growth and health.
