Introductory chapter added to WormBook

Dear WormBook reader,

We are very happy to announce that A Transparent Window into Biology: A Primer on Caenorhabditis elegans, by Ann Corsi, Bruce Wightman, and Marty Chalfie, has just been added to WormBook as a co-publication with GENETICS. This concise and comprehensive review, which serves as an introductory chapter to WormBook, discusses the basic biology, genetics, anatomy, genomics, ecology, and evolution of C. elegans. Key discoveries resulting from research using this organism are described, as is the strong collaborative nature of the worm community. We expect this introduction to provide an invaluable resource for students and others new to C. elegans research and literature.

We thank Tracey DePellegrin, Ruth Isaacson, and Elizabeth De Stasio of GENETICS for their dedication to this collaboration, as well as Editor-in-Chief Mark Johnston for his support of the project.

Nuclear receptor chapter updated in WormBook

Nuclear receptor signal transduction in C. elegans, by Adam Antebi, has just been published in the Signal transduction section of WormBook. This chapter updates his 2006 chapter, Nuclear hormone receptors in C. elegans. The updated chapter discusses the role of nuclear receptors as regulators of life history, cell fate, and organogenesis, and their function in nutrient sensing, metabolism and energy homeostasis.

WormBook: Operon chapter added

Dear WormBook reader,

Operon and non-operon gene clusters in the C. elegans genome, by Thomas Blumenthal, Paul Davis and Alfonso Garrido-Lecca, has been published in the Molecular biology section of WormBook. This chapter discusses a variety of tight-linkage gene arrangements in the C. elegans genome, summarizes the current knowledge on several variations of operon processing, and describes non-operon gene clusters.

Ion transport chapter added to WormBook

Membrane ion transport in non-excitable tissues, by Keith Nehrke, has just been published in the Cell biology section. This chapter discusses calcium signaling during defecation, fertilization, locomotion, and wound closure, as well as the role of pH, proton signaling, and osmotic balance in C. elegans behavior and physiology.

WormBook: Polarity establishment chapter updated

Polarity establishment, asymmetric division and segregation of fate determinants in early C. elegans embryos, by Lesilee Rose and Pierre Goenczy, has been published in the Developmental control and Cell biology sections of WormBook. This chapter updates their 2005 chapter, Asymmetric cell division and axis formation in the embryo. The updated chapter presents important progress in elucidating the mechanisms that transform an isotropic system into a polarized one in the first cell cycle, and further discusses how cell signaling in subsequent divisions builds upon the initial polarity to further refine cell fates.
