Proper PIN1 distribution is needed for root negative phototropism in Arabidopsis. [PDF]
PLoS ONE, 2014 Plants can be adapted to the changing environments through tropic responses, such as light and gravity. One of them is root negative phototropism, which is needed for root growth and nutrient absorption.

From dark to darkness, negative phototropism influences the support-tree location of the massive woody climber Hydrangea serratifolia (Hydrangeaceae) in a Chilean temperate rainforest [PDF]
Plant Signaling & Behavior, 2022 Climbing plants rely on suitable support to provide the light conditions they require in the canopy. Negative phototropism is a directional search behavior proposed to detect a support-tree, which indicates growth or movement away from light, based on ...

CaPHOT1 Negatively Regulates the Pepper Resistance to Phytophthora capsici Infection [PDF]
PlantsPhototropins (PHOTs) are plant blue-light receptors that mediate crucial physiological processes such as phototropism, chloroplast movement, stomatal opening, and flowering. However, the PHOT family genes remain poorly characterized in pepper.

Don’t be MIZguided, know where to grow! [PDF]
Communications BiologyPlant organs shift their directional growth in response to environmental stimuli through tropisms. Arabidopsis roots exhibit positive hydrotropism (towards water) and negative phototropism (away from light).

Negative Phototropism of Chlorophytum comosum Roots and Their Mechanisms
Horticultural Plant Journal, 2015 The aerial roots of Chlorophytum comosum were grown hydroponically, allowing us to study the performance and mechanism of negative phototropism. The results of this study were as follows.

Negative phototropism is seen in Arabidopsis inflorescences when auxin signaling is reduced to a minimal level by an Aux/IAA dominant mutation, axr2. [PDF]
Plant Signal Behav, 2015 Inflorescences of a dominant mutant of Arabidopsis Aux/IAA7, axr2, showed negative phototropism with a similar fluence response curve to the positive phototropism of wild-type stems. Application of a synthetic auxin, NAA, and an inhibitor of polar auxin transport, NPA, increased and decreased respectively the magnitude of the phototropic response in ...
