The genome of retroviruses contains three major coding regions for virion proteins, gag, pol and env. Gag encompasses information for nonglycosylated viral proteins that form the matrix, the capsid and the nucleoprotein structures. From pol derive reverse transcriptase and integrase, and env codes for the surface glycoproteins of the virion which consist of a transmembrane and a surface domain, linked by disulfide bonds. A viral protease is derived eitherfrom the gagorfrom the pol coding region, depending on the virus. Simple retroviruses contain only this elementary gag, pol, and env coding information. Once integrated, they are able to multiply efficiently, using the cellular transcriptional and replication machineries without intervention of viral transacting factors. Most oncogenic retroviruses belong in this category. Complex retroviruses, on the other hand, encode additional nonstructural proteins from multiply spliced messages. These proteins play important regulatory roles in the life cycle of the virus.They function as transacting factors that, in concert with cellular regulatory proteins, control viral gene expression and function and are essential components in the replication of complex retroviruses. To this category belong the lentiviruses, the spumaviruses and a group of oncogenic retroviruses that includes human T cell leukemia virus (HTLV) and bovine leukosis virus(BLV).

New research reveals that plants actively acquire nutrients; This book presents an excellent overview and summary of new concepts of plant nutrient acquisition mechanisms, and sets forth their practical implications in crop production.

Contemporary research reveals that when plants actively acquire nutrients, the acquisition process is not a passive one in which plants simply wait for dissolved nutrients to come closer to their roots. In fact, plants play a far more active role than once was understood to be possible in nutrient acquisition and in adaptation to problem soils. This book presents an overview and summary of modern concepts of plant nutrient acquisition mechanisms, and sets forth their practical implications in crop production. The scope is wide-ranging, from biochemical, molecular, and genetic analysis of nutrient acquisition to global nutritional problems. There are also sections on the cell apoplast, phosphorus-solubilizing organisms, and direct uptake of macro-organic molecules. With contributions by leading scientists worldwide, the book provides a useful resource for researchers in plant and environmental sciences and in agronomy and other branches of agriculture.
