The Allied Genetics Conference was a combined meeting of seven genetics research communities held July 13-17, 2016 in Orlando, Florida. Many talks given throughout the meeting featured compelling images and videos that generated a lot of buzz in various communities. Here, Genes to Genomes is excited to highlight just a few of the wonderful scientific images shared at #TAGC16.
Fly
Chris Large, Nitin Phadnis
“Mechanism of hybrid incompatibility between two subspecies of Drosophila pseudoobscura.” [D118]
Drosophila melanogaster ovaries. Natively-tagged Overdrive is in magenta, F-actin is in yellow, and DNA is in cyan.
Drosophila melanogaster testis. Natively-tagged Overdrive is in magenta, histones are in yellow, and DNA is in cyan.
Firefly
Sarah Sander
“Molecular variation across populations of a widespread North American firefly reveals selection on luciferase but not opsins.” [P335]
Gathering of Souls (2014) by Radim Schreiber. Sander’s crowd-funded project to explore the firefly genome can be found here.
Worm
Daehan Lee, Junho Lee
“QTL mapping for hitchhiking behavior in C. elegans reveals evolutionary trade-off between dispersal and reproduction.” [P377]
A single Caenorhabditis larva displays “nictation.” This behavior – a sort of “dance” to help the worm hitchhike – helps worms disperse to new locations by grabbing rides on other organisms.
A worm “hitchhikes” on a bug.
Yeast
Allison Hall, Mark Rose
“The CWI Pathway Regulates Cell Wall Degradation during Mating.” [Y495]
A yeast MID2 deletion strain (mid2Δ) responding to pheromone. Pheromone-induced morphogenesis causes cell lysis and cell wall degradation.
Loss of cytoplasmic GFP occurs concurrently with cell wall degradation and cell lysis (above).
Zebrafish
Leonard Zon
“Translating Zebrafish Development to the Clinic.” [Genetics and Determinants of Health Joint Plenary Session]
Melanoma initiation at the single-cell level as viewed in zebrafish melanocytes. See an illustration of the process here.
Arabidopsis
Wolfgang Busch
“Allelic variation of an EXOCYST subunit switches between distinct root system architectures.” [P375]
Variations in genotype cause distinct differences in root system architecture in Arabidopsis thaliana. Time-course depicting development of 5 Arabidopsis strains over the first 16 days after germination. Movie by Daniela Ristova and Wolfgang Busch. More on natural genetic and phenotypic variation of roots can be found on the Busch lab website.
Mouse
Anna-Katerina Hadjantonakis
“Single cells get together: cell lineage specification & tissue morphogenesis in the early mouse embryo.” [M304, Rosa Beddington Lecture on Stem Cells]
Blastocyst stage mouse embryo with 3 cell lineages colored.
The midline in an E8.0 mouse embryo visualized at the single cell level. Extra-embryonic cells are in green.
