Book Description
Volume 9 in this series consists of four chapters on vectors that affect human or animal health and six chapters on plant pathogens and their vectors. In Chapter 1, Alex S. Raikhel discusses vitellogenesis in mosquitoes: the cornerstone of the reproductive cycle involving massive production of yolk precursors by the fat body and their accumulation in developing oocytes. In anautogeneous mosquitoes, vitellogenesis is dependent on the availability of a blood meal and, as a consequence, is linked to transmission of pathogens. Therefore, elucidation of mechanisms governing the mosquito vitellogenesis is critical for the successful development of novel strategies in vector and disease management. Previous reviews on mosquito vitellogenesis have dealt predominantly with hormonal control. The goal of this review, however, is to summarize significant progress which has been achieved in understanding mosquito vitellogenesis at the cellular, biochemical and molecular levels. It is with these disciplines that we expect to fully understand the mechanisms governing this key process in mosquito reproduction.

Book Description
This book, now in its second edition, provides researchers and operators a complete description of all aspects regarding the wild ancestor of sugar beet. The possibility of crossing modern crops with the ancestors from which they are derived in order to recover some traits lost through domestication is increasingly attracting interest. The selective process implemented by the first growers led to the elimination of features not considered useful at the time. Yet some of these lost traits have now become very important. In fact, in many areas sugar beet cultivation would now be impossible without the transfer of some genetic resistances from Beta maritima, the crop’s ancestor. Moreover, the isolation of such traits is becoming increasingly critical with regard to current and future environmental and economic considerations on e.g. the use of pesticides. This second edition replaces certain photographs and has been updated to reflect the latest advances and findings. One chapter and several sections have been rewritten, and significant revisions have been made throughout the text. The new techniques provide breeders with massively improved analytical means for the safest and fastest selection procedures. Not only will these techniques allow Beta maritima to take on a far greater role as a source of favorable traits; the relative ease with which these characteristics can be transferred will also make it possible to use the germplasm of the whole genus Beta and Patellifolia, which to date has been highly complex, if not impossible, due to the difficulties of hybridization.
