Root Cap Cuticles Confer a Transient, Penetration-Optimised Phase During Early Seedling Establishment. [PDF]
Plant Cell EnvironABSTRACT Roots emerging from seeds encounter substantial mechanical resistance during soil entry. A transient root cap cuticle (RCC) forms early in development, yet its contribution to root tip function during this mechanically challenging transition remains unclear.

Stochastic processes in gravitropism [PDF]
Frontiers in Plant Science, 2014 In this short review we focus on the role of noise in gravitropism of plants - the reorientation of plants according to the direction of gravity. We briefly introduce the conventional picture of static gravisensing in cells specialized in sensing.

Springback in Root Gravitropism [PDF]
Plant Physiology, 1989 Conditions under which a gravistimulus of Merit corn roots (Zea mays L.) is withdrawn result in a subsequent loss of gravitropic curvature, an effect which we refer to as springback.' This loss of curvature begins within 1 to 10 minutes after removal of the gravistimulus. It occurs regardless of the presence or absence of the root cap.

Regulation of Root Angle and Gravitropism [PDF]
G3 Genes|Genomes|Genetics, 2018 AbstractRegulation of plant root angle is critical for obtaining nutrients and water and is an important trait for plant breeding. A plant’s final, long-term root angle is the net result of a complex series of decisions made by a root tip in response to changes in nutrient availability, impediments, the gravity vector and other stimuli. When a root tip

Auxin transport during root gravitropism: transporters and techniques [PDF]
, 2013 Root gravitropism is a complex, plant-specific process allowing roots to grow downward into the soil. Polar auxin transport and redistribution are essential for root gravitropism.

Arabidopsis shoot gravitropism requires the Mediator coactivator complex [PDF]
, 2022 Gravitropism is a plant response to gravity in directing the growth of its organs, such as the root and the stem. Gravity is sensed by statocytes, unique cells that contain starch-filled amyloplasts, which trigger gravitropic growth response by ...

A stochastic model of root gravitropism [PDF]
, 2017 Gravitropism is a vital process determining plant architecture. As plant architecture is key to resource aquisition a better understanding of gravitropic behaviour may have a great impact on our future food security.

Gravity sensing, a largely misunderstood trigger of plant orientated growth
Frontiers in Plant Science, 2014 Gravity is a crucial environmental factor regulating plant growth and development. Plants have the ability to sense a change in the direction of gravity, which leads to the re-orientation of their growth direction, so-called gravitropism.
