Data from: Phylogenetic utility of ycf1 in orchids: a plastid gene more variable than matK

Kurt M. Neubig, W. Mark Whitten, Barbara S. Carlsward, Mario A. Blanco, Lorena Endara, Norris H. Williams & Michael Moore
Plastid DNA sequences have been widely used by systematists for reconstructing plant phylogenies. The utility of any DNA region for phylogenetic analysis is determined by ease of amplification and sequencing, confidence of assessment in phylogenetic character alignment, and by variability across broad taxon sampling. Often, a compromise must be made between using relatively highly conserved coding regions or highly variable introns and intergenic spacers. Analyses of a combination of these types of DNA regions yield...

Data from: Fitness of Arabidopsis thaliana mutation accumulation lines whose spontaneous mutations are known

Charles B. Fenster, Matthew Thomas Rutter, Angela J. Roles, Jeffrey K. Conner, Ruth G. Shaw, Frank Holcomb Shaw, Korbinian Schneeberger, Stephan Ossowski & Detlef Weigel
Despite the fundamental importance of mutation to the evolutionary process, we have little knowledge of the direct consequences of specific spontaneous mutations to the fitness of the organism. Combining results of whole-genome sequencing with repeated field assays of survival and reproduction, we quantify the combined effects on fitness of spontaneous mutations identified in Arabidopsis thaliana. We demonstrate that the effects are beneficial, deleterious or neutral depending on the environmental context. Some lines, bearing mutations disrupting...
