WebSep 23, 2005 · The starch statolith theory of gravity sensing in higher plants is substantially supported by the induction of curvature responses in vertically growing plant organs after magnetophoretic displacement of statoliths ( Kuznetsov and Hasenstein, 1996, 1997; Kuznetsov et al., 1999; Weise et al., 2000 ). WebTherefore, gravitropism in higher plants has been thought to consist of several sequential processes: gravity sensing, biochemical signal formation, sig- nal transduction, and asymmetric organ growth ( Valster and Blancaﬂ or, 2008 ). Specialized tissues or cells for gravity sensing and signal formation are known as statocytes.
