Annotation	Carbon (C) allocation in rootless Utricularia has not been studied previously. There is uncertainty about the functional and ecological benefit of the trap-associated microbial community and the potential role played by C exudation in enhancing plant–microbe interactions. A ¹³C-labelling experiment was conducted to determine C allocation between plant tissues of increasing age and trap fluid in two Utricularia species. Both species allocated majority of newly fixed C into shoot apex (46.1 +- 8.6% in U. vulgaris and 56.1% in U. australis). Carbon allocation decreased rapidly with increasing age of the shoot. In the trap-bearing shoot segments, ratio of C exuded into trap fluid to that in plant tissues increased markedly with age—in oldest segments twice as much newly fixed C was allocated into the trap fluid than the plant tissue. Overall, a significant amount of the newly fixed C, approximately 25% in both species, was allocated to trap fluid.
