Natural Variation in Maize Aphid Resistance Is Associated with 2,4-Dihydroxy-7-Methoxy-1,4-Benzoxazin-3-One Glucoside Methyltransferase Activity[C][W]
Susceptibility to corn leaf aphid in maize is associated with changes in defense-inducing maize benzoxazinoid levels, with high HDMBOA-Glc levels and low DIMBOA-Glc levels leading to toxicity but aExpand
