Other claims from this paper (6)

Observation Both teosinte species had significantly less caterpillar damage than maize.
Observation Teosinte had trichomes on the upper leaf blade but not the midrib surface.
Observation Z. mays ssp. parviglumis ranked below Z. perennis in trichome density.
Observation Landrace maize had no trichomes at the two- or six-leaf stage.
Mechanism Authors suggest trichomes prevent chewing larval damage in maize ancestors.
Recommendation Genes promoting macrohairs in teosinte could be incorporated into maize.
