چکیده

Current knowledge about the mechanisms of plant root response to gravity is reviewed. The roles of the columella region and amyloplasts in the root cap are examined. Results of experiments related to gravistimulation in corn roots with and without root caps are explained. The role of auxin, abscisic acid, and calcium also are examined.

Gravity and light: integrating transcriptional regulation in roots.

Light and gravity give clues about time and space which plants use to direct their growth. Roots grow towards the vector of gravity (positive gravitropism) to access water and nutrients in the soil and to provide stability. Their response to light depends on its wavelength and intensity. Roots grow towards red light (positive phototropism) and away from blue and white light (negative phototropi...

Touch modulates gravity sensing to regulate the growth of primary roots of Arabidopsis thaliana.

Plants must sense and respond to diverse stimuli to optimize the architecture of their root system for water and nutrient scavenging and anchorage. We have therefore analyzed how information from two of these stimuli, touch and gravity, are integrated to direct root growth. In Arabidopsis thaliana, touch stimulation provided by a glass barrier placed across the direction of growth caused the ro...

Wood specific gravity and anatomy of branches and roots in 113 Amazonian rainforest tree species across environmental gradients.

Wood specific gravity (WSG) is a strong predictor of tree performance across environmental gradients. Yet it remains unclear how anatomical elements linked to different wood functions contribute to variation in WSG in branches and roots across tropical forests. We examined WSG and wood anatomy in white sand, clay terra firme and seasonally flooded forests in French Guiana, spanning broad enviro...

Reactive Oxygen Species Tune Root Tropic Responses1[OPEN]

The default growth pattern of primary roots of land plants is directed by gravity. However, roots possess the ability to sense and respond directionally to other chemical and physical stimuli, separately and in combination. Therefore, these root tropic responses must be antagonistic to gravitropism. The role of reactive oxygen species (ROS) in gravitropism of maize and Arabidopsis (Arabidopsis ...
