Auxin homeostasis is essential for proper development. Drawings of a wild-type seedling and an adult plant (center of the figure in green) and some characterized mutants for auxin homeostasis (in boxes). Mutants with affected auxin biosynthesis are in light brown boxes. sur1 is an overproducer [5] while wei8 tar2 [6] is depleted of auxin. Signaling mutants are shown in light blue boxes and are mutated in the auxin transcription factor 5 (arf5/monopteros) [25], auxin transcriptional inhibitor iaa14 (or solitary root) [26], or the auxin co-receptors (tir1, afb2, afb3) [27]. Mutants for influx (aux1) [28] and efflux auxin transporters (pin1) [7] are shown in the light red boxes
