Figure legends should start with a brief title and should be a self-contained description of the content of the figure that provides enough detail to fully understand the data presented. All conventional symbols used to indicate figure data points are available for typesetting; unconventional symbols should not be used. Italicize all mathematical variables (both in the figure legend and figure) genotypes and additional symbols that are normally italicized. Note that Figures will be automatically converted into PowerPoint-ready slides available for download.
