Phytochrome A Mediates Blue-light Enhancement of Second-positive Phototropism in Arabidopsis
Frontiers in Plant Science, 2016 Hypocotyl phototropism of etiolated Arabidopsis seedlings is primarily mediated by the blue-light receptor kinase phototropin 1 (phot1). Phot1-mediated curvature to continuous unilateral blue light irradiation (0.5 µmol m-2 s-1) is enhanced by overhead ...

Flower movement induced by weather-dependent tropism satisfies attraction and protection [PDF]
Nature CommunicationsFlowers have antagonistic demands for reproductive success, that is, pollinator attraction and flower protection. However, how flowers accommodate these antagonistic reproductive demands has not been thoroughly analysed.

Trajectory Optimization to Enhance Observability for Bearing-Only Target Localization and Sensor Bias Calibration [PDF]
BiomimeticsThis study addresses the challenge of bearing-only target localization with sensor bias contamination. To enhance the system’s observability, inspired by plant phototropism, we propose a control barrier function (CBF)-based method for UAV motion planning.

Interaction of gravitropism and phototropism in roots of Brassica oleracea [PDF]
Environmental and Experimental Botany, 2021 24 p.-9 fig.Gravitropism and phototropism play a primary role in orienting root growth. Tropistic responses of roots mediated by gravity and light have been extensively investigated, and a complex mutual interaction occurs between these two tropisms.

14-3-3 proteins: Central hubs in plant development and stress adaptation. [PDF]
J Integr Plant BiolThis review highlights recent advances elucidating the important roles of 14‐3‐3 proteins in regulating phytohormone networks, biotic and abiotic stress tolerance, growth‐defense trade‐offs, and evolutionary adaptations. Furthermore, it provides a forward‐looking perspective on 14‐3‐3 biology and the development of climate‐resilient smart crops under ...
