Genetically Modified Plants, Second Edition, provides an updated roadmap and science-based methodology for assessing the safety of genetic modification technologies, as well as risk assessment approaches from regulators across different agroecosystems. This new edition also includes expanded coverage of technologies used in plant improvement, such as RNA-dependent DNA methylation, reverse breeding, agroinfiltration, and gene-editing technologies such as CRISPR and TALENS. This book is an essential resource for anyone interested in crop improvement, including students and researchers, practitioners in regulatory agencies, and policymakers involved in plant biotechnology risk assessment.

A transgenic organism is a plant, animal, bacterium, or other living organism that has had a foreign gene added to it by means of genetic engineering. Transgenic plants can arise by natural movement of genes between species, by cross-pollination based hybridization between different plant species (which is a common event in flowering plant evolution), or by laboratory manipulations by artificial insertion of genes from another species. Methods used in traditional breeding that generate transgenic plants by non-recombinant methods are widely familiar to professional plant scientists, and serve important roles in securing a sustainable future for agriculture by protecting crops from pest and helping land and water to be used more efficiently.
There is worldwide interest in the biosafety issues related to transgenic crops because of issues such as increased pesticide use, increased crop and weed resistance to pesticides, gene flow to related plant species, negative effects on nontarget organisms, and reduced crop and ecosystem diversity. This book is intended to provide the basic information for a wide range of people involved in the release of transgenic crops. These will include scientists and researchers in the initial stage of developing transgenic products, industrialists, and decision makers. It will be of particular interest to plant scientists taking up biotechnological approaches to agricultural improvement for developing nations.
* Discusses traditional and future technology for genetic modification
* Compares conventional non-GM approaches and genetic modification
* Presents a risk assessment methodology for GM techniques
* Details mitigation techniques for human and environmental effects

"Comparative Plant Virology" provides a complete overview of our current knowledge of plant viruses, including background information on plant viruses and up-to-date aspects of virus biology and control. It deals mainly with concepts rather than detail. The focus will be on plant viruses but due to the changing environment of how virology is taught, comparisons will be drawn with viruses of other kingdomes, animals, fungi and bacteria. It has been written for students of plant virology, plant pathology, virology and microbiology who have no previous knowledge of plant viruses or of virology in general.
* Boxes highlight important information such as virus definition and taxonomy
* Includes profiles of 32 plant viruses that feature extensively in the text
* Companion website providing image bank
* Full color throughout

The seminal text "Plant Virology" is now in its fifth edition. It has been 10 years since the publication of the fourth edition, during which there has been an explosion of conceptual and factual advances. The fifth edition of "Plant Virology" updates and revises many details of the previous edition while retaining the important earlier results that constitute the field's conceptual foundation. Revamped art, along with fully updated references and increased focus on molecular biology, transgenic resistance, aphid transmission, and new, cutting-edge topics, bring the volume up to date and maintain its value as an essential reference for researchers and students in the field.

The Oregon artist Nelson Sandgren (1917-2006) worked in three distinct media - oil painting, watercolor, and lithography - distinguishing himself in each of these modes throughout his sixty-five-year career. Nelson Sandgren: An Artist's Life is the first in-depth study of this mid-century Oregon modernist who was born in Canada, grew up in Chicago, and moved with his family to Oregon during the Depression. As a watercolorist who loved to paint on site, often on the Oregon coast, Sandgren worked in the tradition of Winslow Homer and John Marin. In oil painting, he combined modernist abstraction with Pacific Northwest landscape imagery, in this practice paralleling Louis Bunce, Carl Morris, and other Oregon moderns. As a lithographer, Sandgren was central to the printmaking culture that Gordon Gilkey promoted at Oregon State university, where Sandgren taught for thirty-eight years. Roger Hull provides a detailed biography and a close analysis of Sandgren's key artworks while demonstrating Sandgren's significant place in Pacific Northwest modernist tradition.

Clifford Gleason (1913-1978), who grew up in Salem and spent his adult life in both Salem and Portland, was a talented and highly original artist whose work remains of keen interest to a small and loyal group of collectors and artists but whose accomplishments are less generally known than those of other Oregon mid-century artists.Clifford Gleason: The Promise of Paint serves as both an introduction and a definitive study of an 'artist's artist,' who until now has not received the sustained attention that he and his work are due. It traces his career from the 1930s until the last months of his difficult life-difficult because of alcoholism, near poverty, and homosexuality in a repressive era. In paint, Gleason found the only realm in which he felt competent, confident, and successful; paint offered the promise of accomplishment. Roger Hull's knowledgeable text offers a chronological study combining biography, analysis of Gleason's artworks, and assessment of his place within the broader context of contemporary and Pacific Northwest art. Published in conjunction with an exhibition at the Hallie Ford Museum of Art at Willamette University, this richly illustrated monograph examines Gleason's identity as a modern artist as he responded to the rapid changes in artistic modernism from the late 1930s, when he studied with Louis Bunce at the Salem Federal Art Center, to the 1970s, when he rethought the legacy of Abstract Expressionism in works that are unique to him, visually beautiful and poetically expressive.
