10 p, 2.1 MB Gibberellin A Metabolism Contributes to the Control of Photoperiod-Mediated Tuberization in Potato / Bou Torrent, Jordi (Institut de Recerca i Tecnologia Agroalimentàries. Centre de Recerca en Sanitat Animal) ; Martínez-García, Jaime F. (Institució Catalana de Recerca i Estudis Avançats) ; García-Martínez, José Luis (Instituto de Biologia Molecular y Celular de Plantas (València, Espanya)) ; Prat, Salomé (Centro Nacional de Biotecología-CSIC)
Some potato species require a short-day (SD) photoperiod for tuberization, a process that is negatively affected by gibberellins (GAs). Here we report the isolation of StGA3ox2, a gene encoding a GA 3-oxidase, whose expression is increased in the aerial parts and is repressed in the stolons after transfer of photoperiod-dependent potato plants to SD conditions.

15 p, 1.7 MB Light signals generated by vegetation shade facilitate acclimation to low light in shade-avoider plants / Morelli, Luca (Centre de Recerca en Agrigenòmica) ; Paulišić, Sandi (Centre de Recerca en Agrigenòmica) ; Qin, Wenting (Centre de Recerca en Agrigenòmica) ; Iglesias Sánchez, Ariadna (Centre de Recerca en Agrigenòmica) ; Roig Villanova, Irma (Centre de Recerca en Agrigenòmica) ; Florez-Sarasa, Igor (Centre de Recerca en Agrigenòmica) ; Rodríguez Concepción, Manuel (Centre de Recerca en Agrigenòmica) ; Martínez García, Jaime F. (Centre de Recerca en Agrigenòmica)
When growing in search for light, plants can experience continuous or occasional shading by other plants. Plant proximity causes a decrease in the ratio of R to far-red light (low R:FR) due to the preferential absorbance of R light and reflection of FR light by photosynthetic tissues of neighboring plants. [...]

Department of Comparative Development and Genetics (Germany)) ; Hothorn, Michael (University of Geneva. Department of Botany and Plant Biology (Switzerland)) ; Martínez García, Jaime F. (Centre de Recerca en Agrigenòmica)
Shade caused by the proximity of neighboring vegetation triggers a set of acclimation responses to either avoid or tolerate shade. Comparative analyses between the shade-avoider Arabidopsis thaliana and the shade-tolerant Cardamine hirsuta revealed a role for the atypical basic-helix-loop-helix LONG HYPOCOTYL IN FR 1 (HFR1) in maintaining the shade tolerance in C. [...]

22 p, 864.7 KB Shedding light on the chromatin changes that modulate shade responses / Martínez García, Jaime F. (Centre de Recerca en Agrigenòmica) ; Moreno Romero, Jordi (Centre de Recerca en Agrigenòmica)
Perception of vegetation proximity or plant shade informs of potential competition for resources by the neighboring vegetation. As vegetation proximity impacts on both light quantity and quality, perception of this cue by plant photoreceptors reprograms development to result in responses that allow plants to compete with the neighboring vegetation.

The shade avoidance syndrome (SAS) allows plants to anticipate and avoid shading by neighbouring plants by initiating an elongation growth response. The phytochrome photoreceptors are able to detect a reduction in the red:far red ratio in incident light, the result of selective absorption of red and blue wavelengths by proximal vegetation. [...]

(Centre de Recerca en Agrigenòmica)
Plants have evolved two major ways to deal with nearby vegetation or shade: avoidance and tolerance. Moreover, some plants respond to shade in different ways; for example, Arabidopsis thaliana undergoes an avoidance response to shade produced by vegetation, but its close relative Cardamine hirsuta tolerates shade.

33 p, 1.8 MB Chloroplasts modulate elongation responses to canopy shade by retrograde pathways involving HY5 and abscisic acid / Ortiz-Alcaide, Miriam (Centre de Recerca en Agrigenòmica) ; Llamas, Ernesto (Centre de Recerca en Agrigenòmica) ; Gómez-Cadenas, Aurelio (Universitat Jaume I) ; Nagatani, Akira (Kyoto University) ; Martínez García, Jaime F. (Centre de Recerca en Agrigenòmica) ; Rodríguez Concepción, Manuel (Centre de Recerca en Agrigenòmica)
Plants use light as energy for photosynthesis but also as a signal of competing vegetation. Using different concentrations of norflurazon and lincomycin, we found that the response to canopy shade in Arabidopsis (Arabidopsis thaliana) was repressed even when inhibitors only caused a modest reduction in the level of photosynthetic pigments. [...]

La luz es esencial para las plantas, no solo como fuente de energía para la fotosíntesis, sino también como una señal de información ambiental que les permite adaptar su desarrollo para prosperar en diferentes escenarios. [...]
Light is essential for plants, not only for fueling photosynthesis, but also as environmental information that allows them to adapt their development to thrive in different scenarios. In shade-avoider (sun-loving) plants, such as Arabidopsis thaliana, proximity of potentially competing vegetation triggers a group of responses known as Shade Avoidance Syndrome (SAS), including the well-studied hypocotyl elongation.

Departament de Biologia Animal, de Biologia Vegetal i d'Ecologia
La luz proporciona energía para la fotosíntesis e información sobre el medio ambiente circundante. La información lumínica avisa de situaciones desafiantes, como la proximidad de la vegetación y la sombra, que requiere de la planta una red de señalización que proporcione respuestas rápidas y ajustadas para adaptar el desarrollo, respuestas que conjuntamente conforman el síndrome de huida de la sombra. [...]
Light provides essential energy for plant photosynthesis and information about the surrounding environment. Light challenging conditions, such as vegetation proximity and shade, require fast response and a fine-tuned signalling network to properly adapt plant development. [...]
