  • Length of sampled regions (bp) is relative to B73 maize inbred genomic sequence, and diversity was estimated for maize, for subsp. parviglumis and subsp. mexicana, and for each teosinte subspecies individually. Sites for which we did not obtain teosinte data are indicated by dashes. For the 0.4-kb and 5′ cDNA sites, we analyzed sequence data reported in two studies (7, 25).
