Genomics Research on Non-Model Plant Pathogens: Delivering Novel Insights into Rust Fungus Biology

Autor: Sébastien Duplessis , Guus Bakkeren , David L Joly

Número de Páginas: 168

Fungi of the order Pucciniales cause rust diseases on many plants including important crops and trees widely used in Agriculture, forestry and bioenergy programs; these encompass gymnosperms and angiosperms, monocots and dicots, perennial and annual plant species. These fungi are obligate biotrophs and -except for a few cases- cannot be cultivated outside their hosts in a laboratory. For this reason, standard functional and molecular genetic approaches to study these pathogens are very challenging and the means to study their biology, i.e. how they infect, develop and reproduce on plant hosts, are rather limited, even though they rank among the most devastating pathogens. Among fungal plant pathogens, rust fungi display the most complex lifecycles for with up to five different spore forms and for many rust fungi, alternate hosts on which sexual and clonal reproduction are achieved. The genomics revolution and particularly the application of new generation sequencing technologies have greatly changed the way we now address biological studies and has in particular accelerated and made feasible, molecular studies on non-model species, such as rust fungi. The goal of this research...

Oxidative Stress and Redox Regulation in Plants

Número de Páginas: 591

The field of redox is rapidly changing, specifically in relation to plants where redox reactions are exacerbated compared to non-photosynthetic organisms. The development of proteomics has allowed the identification of hundreds of molecular targets of these systems, and the recent discovery of glutaredoxin's ability to bind iron sulfur centers (ISCs) and to participate in ISC assembly in other apoproteins has provided many new insights. This volume presents new research on oxidative stress in plants, ranging from the production of reactive oxygen species or reactive nitrogen species, to their accumulation, their involvement in signal transduction, and their degradation, while also covering the links among oxidative stress and biotic and abiotic stresses. - Cutting-edge reviews written from a broad range of scientific perspectives - For over 40 years, series has enjoyed a reputation for excellence - Contributors internationally recognized authorities in their respective fields

Genetics and Evolution of Infectious Diseases

Autor: Michel Tibayrenc

Número de Páginas: 773

Genetics and Evolution of Infectious Diseases is at the crossroads between two major scientific fields of the 21st century: evolutionary biology and infectious diseases. The genomic revolution has upset modern biology and has revolutionized our approach to ancient disciplines such as evolutionary studies. In particular, this revolution is profoundly changing our view on genetically driven human phenotypic diversity, and this is especially true in disease genetic susceptibility. Infectious diseases are indisputably the major challenge of medicine. When looking globally, they are the number one killer of humans and therefore the main selective pressure exerted on our species. Even in industrial countries, infectious diseases are now far less under control than 20 years ago. The first part of this book covers the main features and applications of modern technologies in the study of infectious diseases. The second part provides detailed information on a number of the key infectious diseases such as malaria, SARS, avian flu, HIV, tuberculosis, nosocomial infections and a few other pathogens that will be taken as examples to illustrate the power of modern technologies and the value of...

Lignins

Número de Páginas: 442

Lignins are nature's aromatic polymers and are the second most abundant organic constituent of the biosphere next to cellulose. Lignification mainly occurs in the walls of terrestrial vascular plants, mainly in the secondarily thickened cells of supportive or conductive tissues, which thus acquire novel properties. This new volume of Advances in Botanical Research gives a special emphasis to the bioengineering of these enigmatic polymers. It is divided in nine chapters containing up-to-date reviews by expert groups in their field. - Gives a special emphasis to the bioengineering of these enigmatic polymers, lignins - Divided in nine chapters - Contains up-to-date reviews by expert groups in their field

Recent Trends in Medicinal Plants Research

Autor: Lie-fen Shyur , Allan S. Y. Lau

Número de Páginas: 476

Plants and other living organisms have great potential to treat human disease. There are two distinct types of biomedical research that seek to develop this potential. One type of research explores the value of medicinal plants as traditionally used and studies of these plants have the potential to determine which plants are most potent, optimize dosages and dose forms, and identify safety risks. Another type of research uses bioassays to identify single molecules from plants that have interesting bioactivities in isolation and might be useful lead compounds for the development of pharmaceutical drugs. This new volume of Advances in Botanical Research covers the recent trends in Medicinal Plants Research over 11 chapters. Topics that are covered include Development of Drugs from Plants - Regulation and Evaluation, Chinese Herbal Medicines for Rheumatoid Arthritis, and Taxol, camptothecin and beyond for cancer therapy.

Codon Evolution

Autor: Gina M. Cannarozzi , Adrian Schneider

Número de Páginas: 297

Codon-based models of evolution are a relatively new addition to the toolkit of computational biologists, and in recent years remarkable progress has been made in this area. The study of evolution at the codon level captures information contained in both amino acid and synonymous DNA substitutions. By combining these two types of information, codon analyses are more powerful than those of either amino acid or DNA evolution alone. This is a clear benefit for most evolutionary analyses, including phylogenetic reconstruction, detection of selection, ancestral sequence reconstruction, and alignment of coding DNA. Despite the theoretical advantages of codon based models, their relative complexity delayed their widespread use. Only in recent years, when large-scale sequencing projects produced sufficient genomic data and computational power increased, did their usage become more common. In Codon Evolution, leading researchers in the field of molecular evolution provide the latest insights from codon-based analyses of genetic sequences. The first part of the book provides comprehensive coverage of the developments of various types of codon substitution models such as parametric and...

Guerreros de Dios

Autor: Gabriela Aguilera V.

Número de Páginas: 180

Micronovela en la que los textos se entrelazan funcionando como capítulos y también microrrelatos autónomos y microrrelatos seriados. Relata los acontecimientos que dieron origen a la última guerra de Los Balcanes, una realidad lejana que Gabriela Aguilera acerca a la de cualquier país que haya vivido un conflicto bélico interno. En su entramado, esta micronovela se levanta sobre tres ejes principales: la influencia de la religión en la resolución de conflictos sociales y políticos en algunas culturas, el trabajo del antropólogo forense para identificar a las víctimas de las fosas comunes y la necesidad de ejercer la imprescriptibilidad de los delitos relacionados con violaciones a los derechos humanos además del castigo efectivo a los culpables. Con un lenguaje directo, Guerreros de Dios remite el tiempo al inicio de los poblamientos en la región balcánica y los acontecimientos que terminan de quebrar la convivencia tras la muerte de Tito y la disolución de la ex Yugoeslavia.

Corazón mecánico

Autor: Juan Carlos Quezadas

Número de Páginas: 81

El narrador de esta novela, llamado, al igual que su autor, Juan Carlos Quezadas, se empeña en hacernos creer que lo que leemos no es una novela, sino una crónica, una relación de hechos verídicos. Todo comenzó cuando la editorial Jus le encargó que escribiera una novela de terror para incluirla en su catálogo. El problema fue que a Juan Carlos no se le ocurría nada. Nunca antes había escrito un libro de terror y no se sentía capaz de hacerlo. Por lo tanto, se presentó en la editorial para pedir una ampliación del plazo de entrega de su libro. No encontró a la editora y en vez de esperarla se fue a dar una vuelta por los alrededores. De pronto, se vio ante un pequeño callejón, donde viviría ya no en su imaginación, sino en carne propia esa historia de miedo que tanto buscaba. Cualquier historia ficticia apela a la credulidad del lector en el momento de la lectura; de otro modo no sería posible que quien lee se sintiera sobrecogido por unos conflictos y unos personajes que en el fondo no son más que papel y tinta. En "Corazón Mecánico", esta apelación se vuelve aún más apremiante, ya que el libro nos invita explícitamente a creer en la veracidad de lo que...

Las tristes

Autor: Pía Barros

Número de Páginas: 85

Setenta historias cuenta Pía Barros en su libro, titulado "Las Tristes". Sus relatos exploran todas las formas posibles de contar hechos que marcan la vida. Algunas no sobrepasa las dos líneas, otras encierran en un máximo de tres páginas mundos que se cruzan, encuentran y desencuentran. Así ocurre -por ejemplo- entre dos adolescentes que se pierden y se buscarán en medio de las luchas estudiantiles del Chile actual, en "Desvelos", relato que cierra el libro con más ternura que auténtica tristeza. Barros elige como hilo conductor las mil formas que puede adquirir la melancolía en la vida de mujeres de todas las edades y condiciones. A través del cuento breve, explora el lenguaje en registros que van desde historias absurdas contadas en clave surrealista, hasta la seca crónica del dolor que se adueña de quien vive la hora amarga en que se pronuncian cuatro palabras aterradoras: "Ya no te amo".

Saint Michel

Autor: Gabriela Aguilera V.

Número de Páginas: 138

Mediante una prosa cruzada por la poesía y el realismo, Gabriela Aguilera narra en esta micronovela una historia circular en la que se confunden el habla y el colorete y en donde el coa y las lentejuelas conforman un marco de sentido que nace de la estética recargada y barroca, de la miseria engalanada. La fortaleza carcelaria de Saint Michel totaliza la existencia de quienes tienen la desgracia de ser confinados entre sus muros. Sin embargo, la solidaridad, el amor y la ternura coexisten con el salvajismo y la crueldad. La escritura atraviesa los cuerpos y los muros de Saint Michel y la verdad ocultada y silenciada, inscrita en signos impalpables, aflora a la luz, se expone a los ojos del lector.
