Sentences with phrase «previous molecular studies»
«While previous molecular studies have provided simple snapshots of the gene transcript variations that are associated with the exposure of insects to natural and synthetic chemicals, the genomics approaches used in this study offer a significantly more complex perspective on the biochemical and physiological processes occurring in plant - insect interactions,» Schuler said.
