Methods, Technology and Resources
1. Marker density and read depth for genotyping populations using genotyping-by-sequencing, pp. 1073-1081
Timothy M. Beissinger, Candice N. Hirsch, Rajandeep S. Sekhon, Jillian M. Foerster, James M. Johnson, German Muttoni, Brieanne Vaillancourt, C. Robin Buell, Shawn M. Kaeppler, and Natalia de Leon
Genotyping-by-sequencing enables rapid and efficient genotyping of any species, but it must be appropriately implemented to provide the desired information. This article describes what constitutes sufficient marker information for a variety of genetic studies, and tells how best to obtain that information with genotyping-by-sequencing.
2. Novel sexual-cycle-specific gene silencing in Aspergillus nidulans, pp. 1149-1162
Wioletta Czaja, Karen Y. Miller, and Bruce L. Miller
Homology-dependent gene silencing operates in many fungi, plants, and animals. This article reports a novel gene silencing system in the fungus Aspergillus nidulans that is sexual-cycle-specific. Duplication of the matA gene encoding a master regulator of sexual differentiation triggers Mat-induced silencing of mating type function and abo
