Male fruit flies go through a behavioral progression when courting females that includes: orienting towards the female, following/chasing her, wing vibrations (courtship song), licking her genitalia, attempting copulation, and copulation. The first pair here shows the male quickly progressing through the later stages of courtship. The second couple goes through the progression several times, until finally copulating.

Charalambos ("Bambos") Kyriacou is Professor of Behavioural Genetics at the University of Leicester, UK. His research for a number of years has principally focussed on circadian rhythms (biorhythms) in a variety of organisms, but especially the fruit fly, Drosophila melanogaster. His research group also study aggression and mating behaviour. He also collaborates with Dr Flaviano Giorgini in the Genetics Department in research using fly models to study Huntington's Disease. This is the full interview in which Prof Kyriacou introduces us to the value of Drosophila as a model organism and explains about the importance of biorhythms, including their relevance to human health. This film is part of a collection of resources on the use of model organisms in medical research produced by Dr Chris Willmott and Professor Andrew Fry of the Department of Biochemistry at the University of Leicester. Funded by the Biotechnology and Biological Sciences Research Council and the GENIE Centre for Excellence in Teaching and Learning, these videos show how the use of invertebrate species such as yeast (Saccharomyces cerevisiae) and fruit flies (Drosophila melanogaster) can be applicable to human medicine.

Air date: Wednesday, June 29, 2011, 3:00:00 PM Timedisplayed is Eastern Time, Washington DC Local Category: Wednesday Afternoon Lectures Description: The last twenty years have experienced an unprecedented advance in our understanding of innate immunity in Metazoans and Plants. Up to the early nineties of the last century, little information had been obtained about pathogen recognition by the innate immune system and about the effector mechanisms induced by invading microorganisms. Drosophila, with its easily tractable genetics, can be credited with having made significant contributions to our present understanding of the basics of innate defenses. The presentation will review our current understanding, but will also address the many unresolved questions which await further in-depth analysis. A phylogenetic perspective will try to integrate the data obtained by studying Drosophila immunity, into the more general framework of invertebrate and vertebrate immune defenses The NIH Wednesday Afternoon Lecture Series includes weekly scientific talks by some of the top researchers in the biomedical sciences worldwide.

A three hours hold fruit fly embryo is imaged laterally via fluorescence microscopy for 30 minutes. Myosin is tagged with GFP. This process, called gastrulation, serves in most higher organisms (including humans) for the formation of the three body layers: epi-, meso- and endoderm.

The Bicoid (Bcd) protein gradient is generally believed to be established in pre-blastoderm Drosophila embryos by the diffusion of Bcd protein after translation of maternal mRNA, which serves as a strictly localized source of Bcd at the anterior pole. However, previous reports showed that the Bcd gradient is preceded by a bcd mRNA gradient. These early observations were revisited and extended. The results demonstrate that the bcd mRNA and Bcd protein gradient profiles are virtually identical at all times. This confirms the previous conclusion that the Bcd gradient is produced by a bcd mRNA gradient rather than by diffusion. Based on the observation that bcd mRNA colocalizes with Staufen (Stau), it is proposed that the bcd mRNA gradient forms by a novel mechanism involving quasi-random active transport of a Stau-bcd mRNA complex through a nonpolar microtubular network, which confines the bcd mRNA to the cortex of the embryo.

Quorum's WaveFX confocal system is a laser based system using an optimized Nipkow Spinning technology capable of acquiring confocal images at video rates. This innovative technology significantly reduces photobleaching and photo-toxicity which makes it ideal for studying live cell activity in an undisturbed environment. The increased performance of the system is a result of the several optical modifications unique to Quorum Technologies. This video shows the development of a Drosophila (fruit fly) embryo at high magnification over a 1.5 hour time frame. The fluorescence signal is due to a Histone tagged GFP (Green Fluorescent Protein) construct, and mutiple cell divisions can be seen to occur in unison over the 1+ hour timeframe covered in this video.
