To study how changes in gene regulation shape phenotypic variations in rice, we performed a comparative analysis of genome expression in the heading-stage panicle from six lineages of cultivated and wild rice, including Oryza sativa subsp. indica, japonica and javanica, O. nivara , O. rufipogon and O. glaberrima. While nearly three-quarters of the genes are(More)
Understanding and predicting how species' distributions will shift as climate changes are central questions in ecology today. The late Quaternary of North America represents a natural experiment in which we can evaluate how species responded during the expansion and contraction of the glaciers. Here, we ask whether species' range shifts differ because of(More)
