PhD position in Drosophila neurobiology @ Manchester UK

By | January 8, 2022

A PhD position is available to study bundles of microtubules (MT) that run all along axons in Drosophila brain. The decay of MT bundle decay causes axon degeneration and mechanism underlying this phenomenon forms the basis of this project.

By | January 6, 2022

Post doctoral positions are available in Cassandra Extavour lab at Harvard. Positions to work on two major areas of our research are available: Holobiome Area: Understanding the animal, plant and microbial contributions to the evolution of specific adaptive traits and phenotypic plasticity, using both Drosophila melanogaster and natural populations of wild Drosophila species in Hawaii.… Read More »

How to prepare Hoyer’s medium for Drosophila cuticle preparations

By | January 4, 2022

Importance of cuticle preparations in Drosophila studies: The Drosophila embryonic ventral epidermis has served as a unique tissue for the genetic analysis of patterning. There are two different types of epidermal cells in the ventral epidermis which can be easily distinguished: those that secrete short, thick hair-like structures called denticles and cells that only secrete… Read More »

How to know chromosomal location of a transgenic construct by using a genetic cross ?

By | July 1, 2021

When we generate a new transgene, the first thing which needs to be done is to map its chromosomal location. This can be done at molecular level by performing Inverse Polymerase chain Reaction (iPCR) and subsequent sequencing. It is also possible to efficiently map the P-element insertion (transgene) by doing a simple cross genetic crosses… Read More »

Nobel Prizes for studying Drosophila

By | June 21, 2021

The contribution of Drosophila melanogaster as a invertebrate model in understanding basic aspects of biology is immense. This eventually led to many landmark findings, enabling us to unravel many biological puzzles and find cure for many human diseases. Thanks to the continuous efforts of many scientists and their co-workers, has helped in widening the scope… Read More »

How to balance and generate new fly stocks for genetic crosses

By | June 19, 2021

Drosophila melanogaster was introduced as a model organism more than a century ago. However it was the pioneering work of Thomas Hunt Morgan and his graduate students Sturtevant and Bridges have revolutionized the field of Drosophila genetics and laid the foundation for the present day Invertebrate powerhouse for studying development, physiology and behavior. Since more… Read More »

How to make a recombinant fly line

By | June 14, 2021

Ease of doing genetic experiments makes Drosophila an excellent model system to study development and disease. The reasons for ease in setting up genetic crosses and its subsequent interpretation of results can be attributed to many efficient genetic tools, balancer chromosomes, innumerable genetic markers with clear visible phenotype, mutants for many genes and less number… Read More »

Gal4-UAS system and effect of temperature

By | June 6, 2021

GAL4- UAS system is definitely one of the widely used genetic tool for targeted gene expression in Drosophila. It can be used for both gain of function and loss of function genetic experiments. The wide applicability and everyday use of the system can be attributed to its simple design and availability of lots of reagents… Read More »

Nomenclature of Hox genes

By | May 6, 2021

Lots of confusion prevailed in nomenclature Hox genes , even the name Hox was confusing. A hox gene originally referred to any gene coding for a protein with Homeodomain. In the beginning very few genes where known which could be clearly identified with homeotic mutants of Drosophila. Later huge number of genes with Homeodomain were… Read More »
