Ultraviolet-B induced phototropism in Arabidopsis seedlings and inflorescence stems

, 2018
Ultraviolet-B radiation (UV-B - 280-315nm) was only recently described as a phototropism-inducing type of radiation. We have identified that phototropic growth towards UV-B of Arabidopsis hypocotyls and inflorescence stems are both regulated by the same ...

Defining the Site of Light Perception and Initiation of Phototropism in Arabidopsis

, 2013
SummaryPhototropism is an adaptive response allowing plants to optimize photosynthetic light capture [1–7]. This is achieved by asymmetric growth between the shaded and lit sides of the stimulated organ [8, 9]. In grass seedlings, the site of phototropin-

Arabidopsis nph1 and npl1: Blue light receptors that mediate both phototropism and chloroplast relocation

, 2001
UV-A/blue light acts to regulate a number of physiological processes in higher plants. These include light-driven chloroplast movement and phototropism.

Trajectory Optimization to Enhance Observability for Bearing-Only Target Localization and Sensor Bias Calibration

Biomimetics
This 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.

Discussion on Photoreceptor for Negative Phototropism in Rice Roots

, 2007
: To properly explore the photoreceptor for the negative phototropism in rice (Oryza sativa L.) root, lights with different wavelengths were applied to investigate the effect of light quality on phototropic bending.

Can lateral redistribution of auxin account for phototropism of maize coleoptiles

, 1986
Elongation growth of intact, red-light grown maize (Zea mays L.) coleoptiles was studied by applying a small spot of an indole acetic acid (IAA)-lanolin mixture to the coleoptile tip.

Flower movement induced by weather-dependent tropism satisfies attraction and protection

Nature Communications
Flowers 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.

Recombination between mutants of Phycomyces with abnormal phototropism

, 1976
Sexual crosses were studied between mutants of Phycomyces blakesleeanus with abnormal phototropism (phenotype mad). Recombination frequencies were determined among five genes madA to madE. No clear evidence was found for linkage between any of the genes.
