When upright growing wild type barley seedling are placed to a horizontal position they will respond to this gravistimulation by a curvature against the gravitational force. The mutant serpentina, however, shows gravitropic response only in an early stage of development. Older seedlings, gravistimulated 92 h after germination are agravitropic. They will grow horizontally. We try to identify genes involved in gravitropism by comparing gene expression of i) non-gravistimulated and gravistimulated wild type barley seedlings and of ii) gravistimulated wild type and serpentina.
