Interpretive Summary: Corn is grown on more acreage than any other crop in the US. The genetic makeup of different corn lines is very different, and these differences are the foundation for increasing yield and adaption to different environments. In this paper we report out on the development of a draft genome assembly of one corn line Mo17, and compare it to the genome another genome of corn B73, and found difference more than 5000 genes that were likely to be differences between these lines, based on the locations in the genomes. Cataloging these difference and relating them to difference on how these plants grow and respond to the environment, can have important implications for improving corn plants in the future.

Technical Abstract: Here we report the de novo genome assembly of a corresponding male representative line Mo17 using single-molecule sequencing technology. Over 96.4% of the 2,183 Mb assembled genome can be accounted by 362 scaffolds in 10 pseudo-chromosomes with 44,151 annotated protein-coding genes. Using this Mo17 genome and published B73 reference genome, comparative genomics studies were performed to study the diversity of maize on the whole genome level.
