Brassinosteroid and gibberellin signaling are required for Tomato internode elongation in response to low red: far-red light

This study shows GA and BR are necessary for tomato stem elongation under low R:FR light, with IAA enhancing GA's effect.

Phytochrome-dependent responsiveness to root-derived cytokinins enables coordinated elongation responses to combined light and nitrate cues.

The paper shows how Arabidopsis integrates light and nitrate signals through a root-derived cytokinin pathway to regulate hypocotyl elongation in response to shade and nutrient availability.

Shoot-to-root mobile CEPD proteins regulate TGA transcription factors to allow nitrate root-to-shoot transport in Arabidopsis thaliana

This study shows that CEPD proteins in Arabidopsis thaliana regulate TGA transcription factors to enhance nitrate transport from roots to shoots under nitrogen starvation.

A low-cost and open-source imaging platform reveals spatiotemporal insight into Arabidopsis leaf elongation and movement

The paper introduces a low-cost imaging platform to study Arabidopsis leaf movement and elongation under different light conditions, revealing insights into hyponasty regulation.

Gibberellin transport affects (lateral) root growth through HY5 during Far-Red light enrichment.

The paper shows GA modulates lateral root reduction in response to shoot-sensed FR light through HY5-dependent repression of auxin signaling.

Local light signalling at the leaf tip drives remote differential petiole growth through auxin-gibberellin dynamics

The paper shows that light signals at the leaf tip drive differential petiole growth through auxin and gibberellin dynamics, enabling upward leaf movement.

Mechanodetection of neighbor plants elicits adaptive leaf movements through calcium dynamics

This study identifies a calcium-dependent signaling pathway in Arabidopsis that mediates touch-induced hyponasty, showing it is adaptive in plant competition.

Towards increased shading potential: a combined phenotypic and genetic analysis of rice shoot architecture

Through screening a rice diversity panel for variation in shoot architecture, we identified traits corresponding to plant shading potential and their genetic constituents.

Regulation of lateral root development by shoot-sensed far-red light via HY5 is nitrate-dependent and involves the NRT2.1 nitrate transporter.

This study shows that nitrate signaling suppresses the low R:FR-induced reduction of lateral root growth in Arabidopsis, involving HY5 and NRT2.1.

Mechanisms of far-red light-mediated dampening of defense against Botrytis cinerea in tomato leaves

This study shows that low red:far-red light ratio increases tomato susceptibility to Botrytis cinerea by delaying pathogen detection and reducing jasmonic acid defense responses.

Far-red light enhances soluble sugar levels and Botrytis cinerea disease development in tomato leaves in a jasmonate-dependent manner

This study shows that far-red light increases soluble sugars in tomato leaves, promoting Botrytis cinerea disease through jasmonate-dependent mechanisms.

A gas-and-brake mechanism of bHLH proteins modulates shade avoidance in Arabidopsis thaliana

The paper identifies KIDARI as a positive regulator of shade avoidance and reveals a three-layered network of bHLH protein interactions in Arabidopsis thaliana.

Reducing shade avoidance can improve Arabidopsis canopy performance against competitors

The paper shows that inhibiting hyponastic responses in Arabidopsis can increase canopy biomass and suppress competitors, improving competitive performance against weeds.

Soil salinity inhibits plant shade avoidance

This study shows that soil salinity inhibits plant shade avoidance by interfering with ABA and BR signaling pathways, suppressing PIF function.
