A functional TOC complex contributes to gravity signal transduction in Arabidopsis

Frontiers in Plant Science, 2014
Although plastid sedimentation has long been recognized as important for a plant’s perception of gravity, it was recently shown that plastids play an additional function in gravitropism. The Translocon at the Outer envelope membrane of Chloroplasts (TOC)

Functional mapping of gravitropism and phototropism for a desert tree, Populus euphratica

Frontiers in Bioscience-Landmark, 2021
Background: Plants have evolved the dual capacity for maximizing light assimilation through stem growth (phototropism) and maximizing water and nutrient absorption through root growth (gravitropism).

Distribution of Endogenous NO Regulates Early Gravitropic Response and PIN2 Localization in Arabidopsis Roots

Frontiers in Plant Science, 2018
High-resolution and automated image analysis of individual roots demonstrated that endogenous nitric oxide (NO) contribute significantly to gravitropism of Arabidopsis roots.

Developmental Flower and Rhizome Morphology in Nuphar (Nymphaeales): An Interplay of Chaos and Stability

Frontiers in Cell and Developmental Biology, 2020
European species of Nuphar are amongthe most accessible members of the basal angiosperm grade, but detailed studies using scanning electron microscopy are lacking. We provide such data and discuss them in the evolutionary context. Dorsiventral monopodial

Cellular and physiological functions of SGR family in gravitropic response in higher plants

Journal of Advanced Research
Background: In plants, gravity directs bidirectional growth; it specifies upward growth of shoots and downward growth of roots. Due to gravity, roots establish robust anchorage and shoot, which enables to photosynthesize.

Gravitropic Analysis of Tomato Seedlings using Time Lapse Video Imaging

Bio-Protocol, 2015
Plants use gravity as a guide for growth and development. Gravitropism, a gravity-directed growth process, directs upward shoot movement for efficient photosynthesis and gaseous exchange. In addition, it also directs downward growth of roots in soil, for

Bundling up the Role of the Actin Cytoskeleton in Primary Root Growth

Frontiers in Plant Science, 2021
Primary root growth is required by the plant to anchor in the soil and reach out for nutrients and water, while dealing with obstacles. Efficient root elongation and bending depends upon the coordinated action of environmental sensing, signal ...

Foraging for water by MIZ1-mediated antagonism between root gravitropism and hydrotropism. [PDF]

Proc Natl Acad Sci U S A
Root system integrates multiple environmental cues, chiefly gravity and soil humidity, to anchor plants in soil and forage for water. While the mechanism of auxin-mediated root gravitropism is comparably well-understood, the root’s capability to grow ...

Plant Robotics for Sustainable and Environmentally Friendly Robots: Insights from Actuation Characteristics. [PDF]

Adv Sci (Weinh)
Plants are promising materials for building sustainable and eco‐friendly robots due to their inherent multifunctionality, with actuation playing a crucial role. This article focuses on the physical movements of plants and, from the perspective of actuation characteristics, explores representative plant species and their behaviors, the current state of ...
