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.
当直立生长的野生型大麦幼苗被放置到水平位置时，它们会通过逆着重力方向弯曲来对这种重力刺激做出反应。然而，突变体蛇形大麦（serpentina）仅在发育的早期阶段表现出向重力性反应。发芽92小时后受到重力刺激的较老幼苗是无向重力性的。它们会水平生长。我们试图通过比较以下几种情况的基因表达来鉴定参与向重力性的基因：i）未受重力刺激和受重力刺激的野生型大麦幼苗；ii）受重力刺激的野生型和蛇形大麦。
