Fig 7. Expression pattern of genes involved in auxin signaling.
(A) Orthologues of genes encoding the key enzyme for the biosynthesis of auxin. (B) Orthologues of genes encoding the components in the signal transduction pathways of auxin. Gene IDs were marked on the left. +, up-regulated; -, down-regulated; T, up- and down-regulated compared to the previous growth stage; C, E-type compared with Z-type.
