  • Introduction
  • Centromere DNA and proteins: essential function, rapid evolution
  • Centromeres can be epigenetically specified
  • How can we study animal and plant centromere DNA?
  • Centromere DNA evolution
  • Discover candidate CEN DNA from low pass shotgun sequencing
  • Candidate centromere DNAs from multiple sequencing technologies
  • Analyze 253 animals & plants with public shotgun sequence
  • CEN repeats of non-nucleosomal size
  • Centromere tandem repeats lack common properties
  • Pacific Biosciences sequencing can reveal patterns of evolution
  • Tandem repeat multimers facilitate evolution
  • Switchgrass contains related centromere repeat types
  • Characterize repeat arrays with PacBio sequencing
  • PacBio read statistics
  • Repeat abundance is similar in Sanger and PacBio data
  • Switchgrass repeat arrays are homogeneous
  • PacBio shows higher-order structure in centromere repeat arrays
  • Summary
  • Audience Question 1
  • Audience Question 2
  • Audience Question 3
