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.

Evaluation of Abnormal Hypocotyl Growth of Mutant Capsicum annuum Plants
Agriculture, 2023 Horticulture is a dynamically evolving and an ever-changing sector which needs new ideas, plant materials, and cultivating methods to produce more. Involving different mutants in breeding lines may lead to new opportunities to create new cultivating ...

Plant Phototropic Growth [PDF]
Current Biology, 2015 Plants are photoautotrophic sessile organisms that use environmental cues to optimize multiple facets of growth and development. A classic example is phototropism - in shoots this is typically positive, leading to growth towards the light, while roots frequently show negative phototropism triggering growth away from the light.

Functional mapping of gravitropism and phototropism for a desert tree, Populus euphratica
Frontiers in Bioscience-Landmark, 2021 Background: Plants have evolved the dual capacity for maximizing light assimilation through stem growth (phototropism) and maximizing water and nutrient absorption through root growth (gravitropism).

Diurnal photoperiods and rhythmicity of the phototropic bending response in hypocotyls of sunflower, Helianthus annuus L. seedlings [PDF]
Archives of Biological Sciences, 2021 Research on phototropic (PT) bending in sunflower (Helianthus annuus L. cv. Kondi (Syngenta)) seedling hypocotyls presented herein focused on a comparison of diurnal and free-running photoperiods with the aim of explaining the development of diurnal ...

Comment on 'Lack of evidence for associative learning in pea plants'
eLife, 2020 In 2016 we reported evidence for associative learning in plants (Gagliano et al., 2016). In view of the far-reaching implications of this finding we welcome the attempt made by Markel to replicate our study (Markel, 2020).

THE PHOTOTROPIC MECHANISM IN RANATRA [PDF]
Journal of General Physiology, 1924 Definite proof is obtained that in the phototropic orientation of Ranatra the relative postures of the appendages, resulting in a bilateral difference of effective stroke in swimming, is the mechanism of orientation; the frequency of locomotor movements is the same on the two sides of the body.

Role of Leaves in Phototropism [PDF]
Plant Physiology, 1966 Experiments with green seedlings of sunflower (Helianthus annuns L.) indicate the existence of a phototropic mechanism which involves the leaves or cotyledons, and which can produce an asymmetry of auxin content without the involvement of lateral auxin transport, the classic explanation of phototropism in etiolated seedlings.

Response to comment on 'Lack of evidence for associative learning in pea plants'
eLife, 2020 In 2016 Gagliano et al. reported evidence for associative learning in plants (Gagliano et al., 2016). A subsequent attempt to replicate this finding by the present author was not successful (Markel, 2020). Gagliano et al.
