Figure 5From: Organogenic nodule development in hop (Humulus lupulus L.): Transcript and metabolic responsesCOSY analysis in a sample corresponding to prenodular stage (T15d). Spectrum corresponds to a T15d sample in the range of δ 0.5 to δ 6.2 ppm. Circles highlight correlations of signal at δ 5.55 with δ 5.74 and δ 5.97; and also with signals in aspartate region.Back to article page
