In addition to the segregants, both mating types of the parental strains were barcoded in the same manner as the segregants and ~50 colonies were picked for each parental strain. Whole-genome sequencing of parental haploid segregants Clones containing different barcodes for 1003 MATα and 500 ...
At the same time, two countries that share a history as former colonies of the same colonizer charge each other significantly less for tourist visas. These effects point to an ongoing legacy of the colonial world-system: a certain solidarity between pairs of former colonies and continuing strains...

versus wild-type cells (6 of 60 colonies analysed). Strikingly, the deletion ofSGS1andMPH1rescued the CO events of therad9Δ cells (21 of 99 colonies analysed) (Fig.6b). We also monitored DSB repair by Southern blot in cells blocked in G2/M phase by nocodazole treatment. In agreement...
Group-size variation is common in colonially breeding species, including seabirds, whose breeding colonies can vary in size by several orders of magnitude. Seabirds are some of the most threatened marine taxa and understanding the drivers of colony size
