Figure 1From: Precursor uptake assays and metabolic analyses in isolated tomato fruit chromoplastsIsolation of tomato fruit chromoplasts. Chromoplasts isolated by centrifugation in a discontinuous sucrose density gradient (15, 30, 40 and 50%) (A). Electron micrographs of chromoplasts present in the 15-30% interface (B), 30-40% interface (C) and 40-50% interface (D). Similar electron microscopy images had been taken in two independent chromoplast preparations.Back to article page
