Root Circumnutation Reduces Mechanical Resistance to Soil Penetration. [PDF]
Plant Cell EnvironABSTRACTRoot circumnutation, the helical movement of growing root tips, is a widely observed behaviour of plants. However, our mechanistic understanding of the impacts of root circumnutation on root growth and soil exploration is limited. Here, we deployed a unique combination of penetrometer measurements, X‐ray computed tomography and time‐lapse ...

Circumnutation as an Autonomous Root Movement in Plants [PDF]
American Journal of Botany, 2013 Although publications on circumnutation of the aerial parts of flowering plants are numerous and primarily from the time between and the 1950s, reports on circumnutation of roots are scarce. With the introduction of modern molecular biology techniques, many topics in the plant sciences have been revitalized; among these is root circumnutation.

Circumnutation and Growth of Inflorescence Stems of Arabidopsis thaliana in Response to Microgravity under Different Photoperiod Conditions [PDF]
Life, 2020 Circumnutation is a periodic growth movement, which is an important physiological mechanism of plants to adapt to their growth environments. Gravity and photoperiod are two key environmental factors in regulating the circumnutation of plants, but the ...

Vine-Inspired Continuum Tendril Robots and Circumnutations [PDF]
Robotics, 2018 Smooth-backboned “continuum” robot structures offer novel ways to create robot shapes and movements. In this paper, we show how circumnutation, a motion strategy commonly employed by plants, can be implemented and usefully exploited with ...

Sizing up competition with strigolactones: the case of pea plants [PDF]
Plant Signaling & BehaviorPlants, though sessile, can detect and respond to their neighbors through chemical signals such as strigolactones (SLs). We investigated how SL synthesis and perception affect the climbing behavior of Pisum sativum by analyzing wild-type plants and two ...

Do strigolactones play a role in the ascent and attachment behavior of Pisum sativum? [PDF]
Plant Signaling & BehaviorStrigolactones (SLs) are signaling compounds made by plants. They play a crucial role in acting as long-distance signals from root to shoot to coordinate shoot growth with root environmental conditions.

Temporal Dynamics With and Without a Nervous System: Plant Physiology, Communication, and Movement. [PDF]
Cogn SciAbstract The concept of time has long been the subject of complex philosophical reflections and scientific research, which have interpreted it differently based on the starting question, context, and level of analysis of the system under investigation.

Phosphate promotes Arabidopsis root skewing and circumnutation through reorganisation of the microtubule cytoskeleton. [PDF]
New PhytolSummary Phosphate (Pi) plays a key role in plant growth and development. Hence, plants display a range of adaptations to acquire it, including changes in root system architecture (RSA). Whether Pi triggers directional root growth is unknown. We investigated whether Arabidopsis roots sense Pi and grow towards it, that is whether they exhibit ...

Parasitic Plant-Host Interactions: Molecular Mechanisms and Agricultural Resistance Strategies. [PDF]
Adv Sci (Weinh)Parasitic plants devastate global agriculture through sophisticated molecular interactions with host crops. This review synthesizes current understanding of parasitic plant‐host interactions, from strigolactone‐mediated germination and haustorium formation to host defense mechanisms.
