This image is part of a series displaying seperating fruit flies into 8 groups based on phenotypic characteristics. Fruit fly experiments are performed in Molecular Genetics and Heredity: Biology 207. This image was created as part of the University of Alberta OER image database project in...

Background Gene conversion causes a non-reciprocal transfer of genetic information between similar sequences. Gene conversion can both homogenize genes and recruit point mutations thereby shaping the evolution of multigene families. In the rice genome, the large number of duplicated genes...

Genetic, genomic and molecular studies of signaling pathways controlling ecdysone biosynthesis in Drosophila melanogaster
DownloadFall 2013
In insects, periodic pulses of the molting hormone ecdysone control all major developmental transitions such as the molts and metamorphosis. Ecdysone, a steroid hormone, is produced in the prothoracic gland during larval and pupal development of Drosophila. While we have a relatively good...

Retroposition is widely found to play essential roles in origination of new mammalian and other animal genes. However, the scarcity of retrogenes in plants has led to the assumption that plant genomes rarely evolve new gene duplicates by retroposition, despite abundant retrotransposons in plants...

To maintain an effective barrier, intestinal epithelial progenitor cells must divide at a rate that matches the loss of dead and dying cells. Epithelial damage during most enteric infection accelerates cell proliferation and tissue repair via multiple stress responses. However, infection with the...

Myt1 kinase performs several functions during Drosophila development. Myt1 has firstly been described as a regulator of the G2/M DNA damage checkpoint in the developing wing disc. In addition, Myt1 has been shown to regulate several aspects of male and female gametogenesis, while also...

Investigating the Nuclear Roles of Iron Regulatory Protein-1A (IRP1A) in Drosophila melanogaster
DownloadFall 2023
Iron is an indispensable micronutrient for almost all organisms. Either the lack or excess of iron can result in various human diseases. Therefore, to maintain cellular iron homeostasis, the IRP/IRE (iron regulatory protein/iron responsive element) system tightly regulates iron concentrations....

The ppk20 (pickpocket 20) gene was identified from a two-step screen that was aimed at identifying genes relevant to Drosophila iron and heme homeostasis. Initially, our lab collaborated with two other labs and carried out a prothoracic gland (PG)-specific genome-wide screen of 12,500 RNA...

Intestinal epithelial damage and homeostatic cell shedding sends evolutionarily conserved growth signals to activate division programs in stem cells, which renews the epithelium to maintain barrier integrity. In addition to conserved growth and stress signaling, microbes and innate immune...

If all cells in a multicellular organism contain exactly the same genetic information, the question arises of how tissue types with distinct gene expression profiles are formed and maintained over the life of the organism. These different temporal and spatial gene expression patterns are thought...
