Fig. 4: Dual roles of AU in chlorophyll synthesis and AR primordia initiation.
From: AUREA maintains the balance between chlorophyll synthesis and adventitious root formation in tomato
a Schematic diagrams of AU function in the heme pathway in tetrapyrrole metabolism. b Histological analysis of AR primordia in the hypocotyl of rf at the three- to five-leaf stage. Five-leaf-stage WT plants were used as controls. The red circle shows the AR primordium, and the number below each figure represents the corresponding leaf stage. Bar = 0.2 mm. c The temporal expression pattern of SlHEMA1 in WT and rf. The number below each column represents the corresponding leaf stage. Error bars represent SE (n > 3). d Comparison of HO-1 activity between WT and rf at the two- to four-leaf stage. The number below each column represents the corresponding leaf stage. Error bars represent SE (n > 3)
