Linking phytochrome to plant immunity: low red : far-red ratios increase Arabidopsis susceptibility to Botrytis cinerea by reducing the biosynthesis of indolic glucosinolates and camalexin
(Wiley, 2014-10)
Shade-intolerant plants respond to low red : far-red (R : FR) ratios, which signal the proximity of potential competitors, by down-regulating immune responses. Here we investigated the mechanisms underlying this immune ...
To grow or defend? Low red: far-red ratios reduce jasmonate sensitivity in Arabidopsis seedlings by promoting DELLA degradation and increasing JAZ10 stability
(Wiley, 2014-07)
How plants balance resource allocation between growth and defense under conditions of competitive stress is a key question in plant biology. Low red : far-red (R : FR) ratios, which signal a high risk of competition in ...
Phytochrome B enhances plant growth, biomass and grain yield in field-grown maize
(Oxford University Press, 2019-05-19)
Background and Aims Phytochrome B (phyB) is a photosensory receptor important for the control of plant plasticity and resource partitioning. Whether phyB is required to optimize plant biomass accumulation in agricultural ...
Germinación y latencia de semillas de miconia chartacea (Melastomataceae), en respuesta a luz, temperatura y hormonas vegetales
(2015-01-01)
Miconia chartacea is a widely distributed tree along both altitudinal and latitudinal gradients in Brazil, and it can be found in seasonal xerophytic vegetation, e.g. Caatinga and Cerrado, and tropical rainforest (e.g. ...
Exploring growth-defence trade-offs in Arabidopsis: phytochrome B inactivation requires JAZ10 to suppress plant immunity but not to trigger shade-avoidance responses
(Wiley Blackwell Publishing, Inc, 2017-05)
Under conditions that involve a high risk of competition for light among neighbouring plants, shade-intolerant species often display increased shoot elongation and greater susceptibility to pathogens and herbivores. The ...
Acceleration of flowering during shade avoidance in Arabidopsis alters the balance between FLOWERING LOCUS C-mediated repression and photoperiodic induction of flowering.
(American Society of Plant Biologist, 2008-09)
The timing of the floral transition in Arabidopsis (Arabidopsis thaliana) is influenced by a number of environmental signals. Here, we have focused on acceleration of flowering in response to vegetative shade, a condition ...
Red to Far-red Ratio During Seed Development Affects Lettuce Seed Germinability and Longevity
(AMER SOC HORTICULTURAL SCIENCE, 2009)
Thermoinhibition and photosensitivity are two characteristics of lettuce seed that frequently affect its stand. The main objective of this study was to evaluate the hypothesis that lettuce seed germinability and longevity ...
The action of the testa upon the germination of seeds of Cucumis anguria L.
(1988-01-01)
In negatively photoblastic seeds of Cucumis anguria L. the scarification of micropyle overcame the inhibitory effect of white light , although far-red radiation inhibited the germination in both intact and scarified seeds. ...
