Abstract Micromanipulators, more than any other instrument, opened the early doors to developing the powerful genetics of yeast that underlies much of the molecular work today. The ability to separate the spores of a tetrad and analyze their phenotypes generated the genetic maps and biology upon which subsequent cloning, sequencing, cutting edge molecular and cell biology depended. This work describes the development of those micromanipulators from garage to barn to factory and the developer of the sophisticated instruments we use today. For more than 30 years Carl Singer and his family were staunch and generous supporters of the International Conferences on Yeast Genetics and Molecular Biology meetings both in Europe and America. Carl Singer's displays at meetings became a traditional fixture and engaged the appetites of many students and advanced researchers to employ a technique that many perceived as too complicated or difficult, but which he made simple and easy to learn. His experiences also document a sketch of the international yeast meetings, their venues and how they developed through the years.

ABSTRACT Felipe Santiago-Tirado studies the cell biology of cryptococcal infections. In this mSphere of Influence article, he reflects on how the papers “Systematic Genetic Analysis of Virulence in the Human Fungal Pathogen Cryptococcus neoformans” (https://doi.org/10.1016/j.cell.2008.07.046) and “Unraveling the Biology of a Fungal Meningitis Pathogen Using Chemical Genetics” (https://doi.org/10.1016/j.cell.2014.10.044) by the Noble and Madhani groups influenced his thinking by showcasing the various modern applications of yeast genetics in an organism where genetic manipulation was difficult.

Conventional plant breeding has made a significant impact on the increase in crop production during the last half century. Several shortcomings however, opened up the opportunities for the application of biotechnology in plant breeding. The vari­ous approaches in the field of cell biology (tissue culture) and molecular biology (recombinant DNA technology) are dis­cussed and the application thereof is advocated in a global approach to plant breeding.

Rubella virus is a small, enveloped, positive-stranded RNA virus in the Togaviridae family and bears similarities to the prototype alphaviruses in terms of its genome organization and strategy for viral gene expression. Despite being an important human pathogen, the cell biology of rubella virus remains poorly characterized. This review focuses on the molecular biology of rubella virus structural proteins, with emphasis on the proteolytic processing and maturation of virus structural proteins, the glycosylation requirement for intracellular transport and function of glycoproteins, and the localization of hemagglutinin- and virus-neutralizing epitopes. A number of significant differences between rubella virus and alphavirus structural protein expression and maturation were discovered.Key words: rubella virus, N-linked glycosylation, epitope mapping, proteolytic processing.

There are thousands of maize mutants, which are invaluable resources for plant research. Geneticists use them to study underlying mechanisms of biochemistry, cell biology, cell development, and cell physiology. To streamline the understanding of such complex processes, researchers need the most current versions of genetic and physical maps, tools with the ability to recognize novel phenotypes or classify known phenotypes, and an intimate knowledge of the biochemical processes generating physiological and phenotypic effects. They must also know how all of these factors change and differ among species, diverse alleles, germplasms, and environmental conditions. While there are robust databases, such as MaizeGDB, for some of these types of raw data, other crucial components are missing. Moreover, the management of visually observed mutant phenotypes is still in its infant stage, let alone the complex query methods that can draw upon high-level and aggregated information to answer the questions of geneticists. In this paper, we address the scientific challenge and propose to develop a robust framework for managing the knowledge of visually observed phenotypes, mining the correlation of visual characteristics with genetic maps, and discovering the knowledge relating to cross-species conservation of visual and genetic patterns. The ultimate goal of this research is to allow a geneticist to submit phenotypic and genomic information on a mutant to a knowledge base and ask, "What genes or environmental factors cause this visually observed phenotype?".
