Figure 1From: Transcriptional profiling of sweetpotato (Ipomoea batatas) roots indicates down-regulation of lignin biosynthesis and up-regulation of starch biosynthesis at an early stage of storage root formationMicroscopic view of adventitious root cross sections 26 days after transplanting. A. Fibrous root (FR) cross section. B. Initiated storage root (ISR) cross section. Tissue sections were taken at 3 cm from the proximal root part and stained with toluidine blue. LC – lignified cells; AC – anomalous cambium; RVC – regular vascular cambium. Scale bars = 0.1 mm.Back to article page
