Aerial root mucilage (ARM) and underground root exudate (URE) compound of H. rotundifolia. a Creeping H. rotundifolia with aerial root and mucilage of varying lengths. White scale bars = 1 cm. b Sampling diagram of aerial root mucilage and underground root exudates. c Principal component analysis result of widely targeted metabolome of ARM and URE. d Relative content of different compounds of ARM and URE. Blue indicates that the content of URE is higher than that of ARM, and red indicates that the content of ARM is higher than that of URE. See also Table S1-1. e Carbohydrate content of aerial root mucilage and underground root exudate, on average, n = 6. See also Table S1-2
