Gravity is a permanent environmental signal guiding plant growth and development. Gravity sensing in plants starts with the displacement of starch-filled plastids called statoliths, ultimately leading to auxin redistribution and organ curvature. Whil

The effects of the mechanical disruption of the thin actin network of statocytes on gravisensitivity have been studied on lentil roots. Seedling roots were first inverted for 7 min (root tip upward) and then placed in the downward (normal) position f

Summary The actin cytoskeleton has been implicated in regulating plant gravitropism. However, its precise role in this process remains uncertain. We have shown previously that disruption of the actin cytoskeleton with Latrunculin B (Lat B) strongly p

The analysis of the dose-response curve of the gravitropic reaction of lentil seedling roots has shown that these organs are more sensitive when they have been grown in microgravity than when they have been grown on a 1 g centrifuge in space before g

In the gravity-perceiving cells (statocytes), located in the centre of the root cap, polarity is expressed in the arrangement of the organelles since, in most genera, the nucleus and the endoplasmic reticulum are maintained at the opposite ends of ea

The study of gravitropism in space has permitted the discovery that statoliths are not completely free to sediment in the gravisensing cells of roots. These organelles are attached to actin filaments via motor proteins (myosin) which are responsible

The dose-response curve of the gravitropic reaction is often used to evaluate the gravisensing of plant organs. It has been proposed (Larsen 1957) that the response (curvature) varies linearly as a function of the logarithm of the dose of gravistimul

The morphometry of the root system, the meristematic activity and the level of indole-3-acetic acid (IAA), abscisic acid (ABA) and zeatin in the primary root tips of rapeseed seedlings were analyzed as functions of time on a slowly rotating clinostat

Seedlings of Brassica napus were cultivated on a slowly rotating clinostat (1 rpm) or in the vertical control for 5 d. The root growth, the cotyledonary reserves and the transport of 14C-labeled sucrose from cotyledons to root system were studied in

Root growth and cell differentiation were analysed in lentil seedlings grown (1) in microgravity (F microg), (2) on the 1 x g centrifuge (F1 x g), (3) in microgravity and placed on the 1 x g centrifuge for 4 h [F(microg + 1 x g)], (4) on the 1 x g ce
