The papers in between discuss the relationship of other tropisms to gravitropism, auxin transport, single-cell systems as model organisms, light perception, moisture gradients, and touch sensing mechanisms.
This population has been used to analyze other LP adaptation traits such as root hair density, acid exudation, and basal root gravitropism (Liao et al.
2000), however, discussed how root architecture is principally controlled by gravitropism, where gravitropism determines the depth at which laterals form.
One option for an active gravireceptor is an intracellular statolith exerting pressure on a sensor, as has been proposed for gravitropism in higher plants.
While there are a number of long-appreciated examples of gravitropism involving intact higher plants (Larsen, 1962; Firn & Myers, 1987; Salisbury, 1993) and higher fungi (Moore, 1991), and even explanted organs such as the pulvini of grasses (Kaufman et al.
