The success of Drosophila melanogaster as a model organism is largely due to the power of forward genetic screens to identify the genes that are involved in a biological process. Traditional screens, such as the Nobel-prize-winning screen for embryonic-patterning mutants, can only identify the earliest phenotype of a mutation. This review describes the ingenious approaches that have been devised to circumvent this problem: modifier screens, for example, have been invaluable for elucidating…

The contribution of the fruit fly to science and medicine continues in the postgenomic era as cell-based Drosophila RNAi screens are a cost-effective and scalable enabling technology that can be used to quantify the contribution of different genes to diverse cellular processes.

The art and design of genetic screens: RNA interference

The current state of the art for RNAi screening is described, and the importance of well-designed assays and of analytical approaches for large-scale screening experiments is stressed, from high-throughput screens using simplified homogenous assays to microscopy and whole-animal experiments.

High-throughput RNAi screen in Drosophila.

This chapter discusses the application, advantages, and limitations of this powerful technology in the identification of novel modulators of cell-signaling pathways as well as its future scope and utility in designing more efficient genome-scale screens.

Drosophila, Genetic Screens, and Cardiac Function

Fly genetics and genomics offer new approaches for gene discovery of adult cardiac phenotypes to identify evolutionarily conserved molecular signals that drive cardiovascular disease.

Tailoring the genome: the power of genetic approaches

The current approaches to these questions in four of the most advanced models organisms: Saccharomyces cerevisiae (yeast), Caenorhabditis elegans (worm), Drosophila melanogaster (fly) and Mus musculus (mouse) are summarized.

Strategies for gene disruption in Drosophila

This review discuss important factors that should be taken into consideration for the selection of a strategy that best fits the specific needs of a gene knockout project and evaluate the pros and cons of each technique in a historical perspective.

The past, present and future of gene targeting in Drosophila

Gene targeting in Drosophila, developed almost a decade ago, makes use of the organism's own DNA repair machinery to exchange genetic information between a chromosomal target and an exogenous template.

An F1 Genetic Screen for Maternal-Effect Mutations Affecting Embryonic Pattern Formation in Drosophila melanogaster

A genetic mosaic screen aimed at identifying new maternal genes required for early embryonic patterning, including zygotically required ones is performed using the Flp-FRT technique and a visible germline clone marker to develop a system that allows efficient screening for maternal-effect phenotypes after only one generation of breeding.



Systematic gain-of-function genetics in Drosophila.

The ability of the modular misexpression system to identify developmentally important genes is demonstrated and it is suggested that it will be generally useful for genetic interaction screens.

A versatile misexpression screen in Drosophila, the first such screen in higher eukaryotes, is developed, based on Gal4 transactivation of a mobile enhancer and promoter that "targets" random endogenous genes for expression.

Analysis of genetic mosaics in developing and adult Drosophila tissues.

This work has constructed a series of strains to facilitate the generation and analysis of clones of genetically distinct cells in developing and adult tissues of Drosophila, providing an unprecedented opportunity to perform systematic genetic screens for mutations affecting many biological processes.

A genetic method for generating Drosophila eyes composed exclusively of mitotic clones of a single genotype.

A genetic method is described that uses both the GAL4/UAS and FLP/FRT systems to overcome this limitation for the Drosophila eye by producing genetically mosaic flies that are otherwise heterozygous but in which the eye is composed exclusively of cells homozygous for one of the five major chromosome arms.

Zygotic lethal mutations with maternal effect phenotypes in Drosophila melanogaster. II. Loci on the second and third chromosomes identified by P-element-induced mutations.

64 new loci whose gene products are required for proper egg formation or normal embryonic development are identified by using the autosomal "FLP-DFS" technique to screen a collection of 496 P element-induced mutations established by the Berkeley Drosophila Genome Project.

Identifying tumor suppressors in genetic mosaics: the Drosophila lats gene encodes a putative protein kinase.

One of the identified genes, lats, has been cloned and encodes a putative protein kinase that shares high levels of sequence similarity with three proteins in budding yeast and Neurospora that are involved in regulation of the cell cycle and growth.

Mutations affecting segment number and polarity in Drosophila

The phenotypes of the mutant embryos indicate that the process of segmentation involves at least three levels of spatial organization: the entire egg as developmental unit, a repeat unit with the length of two segments, and the individual segment.

The genome sequence of Drosophila melanogaster.

The nucleotide sequence of nearly all of the approximately 120-megabase euchromatic portion of the Drosophila genome is determined using a whole-genome shotgun sequencing strategy supported by extensive clone-based sequence and a high-quality bacterial artificial chromosome physical map.

Genetic screens to identify elements of the decapentaplegic signaling pathway in Drosophila.

The results of screens for genes required to maximize dpp signaling during embryonic dorsal-ventral patterning are described and it is proposed that Mad and Medea encode rate-limiting components integral to dpp pathways throughout development.

Functional genomic analysis of cell division in C. elegans using RNAi of genes on chromosome III

A functional genomic screen to identify genes required for cell division in Caenorhabditis elegans using an in vivo time-lapse differential interference contrast microscopy assay and found that this screen provides putative gene functions for other species as well.
