How is a ligule patterned? Summary of the known gene expression patterns in the developing grass leaf at P6 and the hypothetical gradients of phytohormone signaling. Green represents the expression pattern of the BOP homologues, which overlaps with LG3, BRD1, and BEL14 in the base of the leaf. The dotted region represents the pre-ligule band, where PIN1a, BEL12, ELIA, CUC2, LG1, and GLU1 are expressed. Hypothesized gradients are also illustrated for Auxin, CK, and BR.
