Rangel, Juliana; Strauss, Kim; Seedorf, Kaileah; Hjelmen, Carl E.; Johnston, J. Spencer (PLOS, 2015-04-16)Honey bees (Apis mellifera) exhibit age polyethism, whereby female workers assume increasingly complex colony tasks as they age. While changes in DNA methylation accompany age polyethism, other DNA modifications accompanying ...
