Light as Stress Factor to Plant Roots – Case of Root Halotropism

Frontiers in Plant Science, 2014
Despite growing underground, largely in darkness, roots emerge to be very sensitive to light. Recently, several important papers have been published which reveal that plant roots not only express all known light receptors but also that their growth ...

Positive/Negative Phototropism: Controllable Molecular Actuators with Different Bending Behavior [PDF]

, 2020
Herein, a series of molecular actuators based on the crystals of (E)‐2‐(4‐fluorostyryl)benzo[d]oxazole (BOAF4),(E)‐2‐(2,4‐difluorostyryl)benzo[d]oxazole (BOAF24), (E)‐2‐(4‐fluorostyryl)benzo[d]thiazole (BTAF4) and (E)‐2‐(2,4‐difluorostyryl)benzo[d]thiazole (BTAF24) showed unprecedented different bending behavior under UVirradiation.

High Pigment1 Mutation Negatively Regulates Phototropic Signal Transduction in Tomato Seedlings [PDF]

Plant Physiology, 2004
Abstract Phototropins and phytochromes are the major photosensory receptors in plants and they regulate distinct photomorphogenic responses. The molecular mechanisms underlying functional interactions of phototropins and phytochromes remain largely unclear.

Blue‐light‐induced PIN3 polarization for root negative phototropic response in Arabidopsis [PDF]

The Plant Journal, 2013
SummaryRoot negative phototropism is an important response in plants. Although blue light is known to mediate this response, the cellular and molecular mechanisms underlying root negative phototropism remain unclear. Here, we report that the auxin efflux carrier PIN‐FORMED (PIN) 3 is involved in asymmetric auxin distribution and root negative ...

Negative Phototropism of the Creeping Shoots in Japanese Ivy, Hedera rhombea.

Journal of the Japanese Forest Society, 2011
付着根型つる植物であるキヅタ (ウコギ科) の匍匐シュートの伸長方向と光環境の関係を実験的に解析した。匍匐シュートに傾度のある光環境条件を与えた場合, 10 mm以上伸長したすべてのシュートで, キヅタは負の光屈性を示した。また, その負の光屈性は, シュートの先端が水平方向と垂直方向の光強度が均一に低下するような空間をめざして伸長するように生じていた。シュートの伸長量は光量の減少にしたがって低下したが, 20 μmol/m2/sという弱光環境においても負の光屈性は生じていた。つまり, キヅタの匍匐シュートの負の光屈性は, 単なる強光を避ける反応ではなく, 三次元空間的な光環境で暗所方向へ伸長する反応であった。この負の光屈性は, つる植物が林床の不均一な光環境下で ...

Adaptive Genomic Divergence Across Altitudes in Capsella bursa‐pastoris

Biological Diversity, EarlyView.
Genomic divergence was observed between high‐altitude and low‐altitude populations of Capsella bursa‐pastoris in China, consistent with an important role of ecological factors. Candidate adaptive loci associated with enhanced energy metabolism, photoprotection, and growth plasticity under altitudinal stress were identified.

Spatiotemporal Metabolome and Single‐Nucleus Transcriptome Integration Illuminates an Auxin Gradient Orchestrated by NtTAC1 Underlying Leaf Angle Regulation in Tobacco

Plant Biotechnology Journal, EarlyView.
Proposed model of TAC1‐mediated leaf angle regulation in tobacco. ABSTRACT Plant architecture is key to crop yield, with leaf angle being critical for high‐density cultivation. Although TAC1 represents a promising regulator of leaf angle for breeding, its molecular mechanism remains poorly understood, particularly at single‐nucleus resolution. Here, we
