Population genomics of post-glacial western Eurasia
Allentoft, Morten E.; Sikora, Martin; Refoyo-Martínez, Alba; Irving-Pease, Evan K.; Fischer, Anders; Barrie, William; Ingason, Andrés; Stenderup, JesperWestern Eurasia witnessed several large-scale human migrations during the Holocene1,2,3,4,5. Here, to investigate the cross-continental effects of these migrations, we shotgun-sequenced 317 genomes—mainly from the Mesolithic and Neolithic periods—from across northern and western Eurasia. These were imputed alongside published data to obtain diploid genotypes from more than 1,600 ancient humans. Our analyses rev...
Laser Capture Microdissection Protocol for Xylem Tissues of Woody Plants
Blokhina, Olga; Valerio, Concetta; Sokołowska, Katarzyna; Zhao, Lei; Kärkönen, Anna; Niittylä, Totte; Fagerstedt, KurtLaser capture microdissection (LCM) enables precise dissection and collection of individual cell types from complex tissues. When applied to plant cells, and especially to woody tissues, LCM requires extensive optimization to overcome such factors as rigid cell walls, large central vacuoles, intercellular spaces, and technical issues with thickness and flatness of the sections. Here we present an optimized prot...
