Abstract excerpt
BACKGROUND: Soybean underpins Brazil's agricultural, yet its sustainability is threatened by lepidopteran pests such as Anticarsia gemmatalis. Although insect-resistant cultivars have long been associated with the constitutive accumulation of quercetin-derived flavonols, the biochemical mechanisms underlying this resistance remain poorly understood. In particular, the role of flavonol O-methylation in enhancing...
