Functional mapping of gravitropism and phototropism for a desert tree, Populus euphratica
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).

Comment on 'Lack of evidence for associative learning in pea plants'
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).

Response to comment on 'Lack of evidence for associative learning in pea plants'
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.

The blue light photoreceptors, phototropin 1 (phot1) and phot2, and their signal transducer, NONPHOTOTROPIC HYPOCOTYL3 (NPH3), are activators of the phototropic responses of Arabidopsis hypocotyls.

Negative Phototropism of Chlorophytum comosum Roots and Their Mechanisms
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.

A unified model of shoot tropism in plants: photo-, gravi- and Propio-ception. [PDF]
Land plants rely mainly on gravitropism and phototropism to control their posture and spatial orientation. In natural conditions, these two major tropisms act concurrently to create a photogravitropic equilibrium in the responsive organ.

A phosphorylation switch turns a positive regulator of phototropism into an inhibitor of the process
Light conditions modify plant growth and development via photoreceptors such as phototropins. Here the authors show that while phot1 promotes phototropism under low light, it can act to suppress phototropism in high-light environments through ...

ALS as Tool to Study Preferred Stem Inclination Directions
Although gravitropism forces trees to grow vertically, stems have shown to prefer specific orientations. Apart from wind deforming the tree shape, lateral light can result in prevailing inclination directions.
