Amphicarpic development in Cardamine chenopodiifolia

New Phytologist, Volume 244, Issue 3, Page 1041-1056, November 2024.
Summary Amphicarpy is an unusual trait where two fruit types develop on the same plant: one above and the other belowground. This trait is not found in conventional model species. Therefore, its development and molecular genetics remain under‐studied. Here, we establish the allooctoploid Cardamine chenopodiifolia as an emerging experimental system to ...

Light‐Driven Multidirectional Bending in Artificial Muscles

Advanced Materials, Volume 36, Issue 38, September 19, 2024.
Fast light‐triggered multidirectional bending is demonstrated in soft twist‐coiled artificial muscles. The bending direction is dictated by the direction of the light leading to localized untwisting of the muscle. These artificial muscles can autonomously turn toward a light source, and they can be programmed for selective, reversible, and sustained ...

Ascent and Attachment in Pea Plants: A Matter of Iteration

Plants
Pea plants (Pisum sativum L.) can perceive the presence of potential supports in the environment and flexibly adapt their behavior to clasp them. How pea plants control and perfect this behavior during growth remains unexplored.

All tangled up: Unraveling phylogenetics and reticulate evolution in the vining ferns, Lygodium (Schizaeales)

American Journal of Botany, Volume 111, Issue 9, September 2024.
Abstract Premise Reticulate evolution, often accompanied by polyploidy, is prevalent in plants, and particularly in the ferns. Resolving the resulting non‐bifurcating histories remains a major challenge for plant phylogenetics. Here, we present a phylogenomic investigation into the complex evolutionary history of the vining ferns, Lygodium (Lygodiaceae,

Climbing mechanisms as a central trait to understand the ecology of lianas across the tropics

Global Ecology and Biogeography, Volume 33, Issue 7, July 2024.
Abstract Aims Lianas are a central component of tropical forests. However, how the type of climbing mechanisms is related to the functional and taxonomic diversity of lianas across the tropics, remains largely unresolved. Here, we tested two main hypotheses: (i) the functional diversity of lianas differs with climbing mechanism (active and passive) and

A Soft Continuum Robotic Arm with a Climbing Plant‐Inspired Adaptive Behavior for Minimal Sensing, Actuation, and Control Effort

Advanced Intelligent Systems, Volume 6, Issue 4, April 2024.
A quantitative biomimetic approach allows for building soft continuum arms inspired by twining climbing plants. Designed to mimic the flexural rigidity of terminal stems of Mandevilla cf. splendens, the robot detects the presence of a support and twines around it, without requiring a central computing unit.

Rising from the shadows: Selective foraging in model shoot parasitic plants

Plant, Cell &Environment, Volume 47, Issue 4, Page 1118-1127, April 2024.
Abstract Despite being sessile, plants nonetheless forage for resources by modulating their growth. Adaptative foraging in response to changes in resource availability and presence of neighbours has strong implications for performance and fitness. It is an even more pressing issue for parasitic plants, which draw resources directly from other plants ...

Toward Bionic Arthroscopy: A Comprehensive Perspective of Continuum Robotics Principles and Prototypes for the Inception of Arthroscopic Surgery Robots

Advanced Intelligent Systems, Volume 6, Issue 3, March 2024.
This article explores integrating bionics with continuum robotics to innovate in arthroscopic surgery. Inspired by adaptable organisms like snakes and octopuses, in the study, the challenges and opportunities of implementing continuum robots in arthroscopy are delved into.

Orchid fruit and root movement analyzed using 2D photographs and a bioinformatics pipeline for processing sequential 3D scans

Applications in Plant Sciences, Volume 12, Issue 1, January-February 2024.
Abstract Premise Most studies of the movement of orchid fruits and roots during plant development have focused on morphological observations; however, further genetic analysis is required to understand the molecular mechanisms underlying this phenomenon.

Sizing up competition with strigolactones: the case of pea plants

Plant Signaling & Behavior
Plants, 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 ...
