The terrestrial environment is complex, with many parameters fluctuating on daily and seasonal basis. Plants in particular, have developed complex sensory and signalling networks to extract and integrate information about their surroundings, in order to maximise their fitness and mitigate some of the detrimental effects of their sessile lifestyles. Light and temperature each provide crucial insight on the surrounding environment and in combination allow plants to appropriately develop, grow and adapt. Crosstalk between light and temperature signalling cascades allow plants to time key developmental decisions accordingly to ensure they are "in sync" with their environment. In this review, we discuss the major players that regulate light and temperature signalling, and the cross-talk between them, in reference to a crucial developmental decision faced by plants: to bloom or not to bloom?

FRIGIDA (FRI) as the major regulator of flowering time in Arabidopsis accessions can activate its target FLOWERING LOCUS C (FLC) to delay flowering before vernalization. Besides FLC, other FRI targets...
In response to competition for light from the neighbors, shade-intolerant plants flower precociously to ensure reproductive success and survival. However, the molecular mechanism regulating this key d...
Flowering time is a key process in plant development. Photoperiodic signals play a crucial role in the floral transition in Arabidopsis thaliana and CONSTANS (CO) protein has a central regulatory func...
Flowering transition is regulated by complex genetic networks in response to endogenous and environmental signals. Pre-mRNA splicing is an essential step for the post-transcriptional regulation of gen...
In angiosperms, floral transition is a key developmental transition from the vegetative to reproductive growth, and requires precise regulation to maximize the reproductive success. A complex regulato...
Since 1960, persons with the very rare disorder Bloom's syndrome (BS) have been followed clinically, documenting clinical matters as obtained from their doctors. This has been a worldwide...
The purpose of this study is to determine whether red light therapy using LED 650nm red light for body contouring of the waist, hips and thighs is as effective as red light therapy using L...
This randomized phase I/II clinical trial is studying the side effects and best dose of gamma-secretase/notch signalling pathway inhibitor RO4929097 when given together with vismodegib and...
This study is designed to investigate whether light therapy may be an effective treatment for some people with epilepsy. Light treatment is already an established treatment for depression....
The purpose of this study is to determine whether red light therapy using LED 635nm red light for body contouring of the waist, hips and thighs is as effective as red light therapy using L...
Proteins that originate from plants species belonging to the genus ARABIDOPSIS. The most intensely studied species of Arabidopsis, Arabidopsis thaliana, is commonly used in laboratory experiments.
An algal bloom where the algae produce powerful toxins that can kill fish, birds, and mammals, and ultimately cause illness in humans. The harmful bloom can also cause oxygen depletion in the water due to the death and decomposition of non-toxic algae species.
An autosomal recessive disorder characterized by telangiectatic ERYTHEMA of the face, photosensitivity, DWARFISM and other abnormalities, and a predisposition toward developing cancer. The Bloom syndrome gene (BLM) encodes a RecQ-like DNA helicase.
A plant genus of the family BRASSICACEAE that contains ARABIDOPSIS PROTEINS and MADS DOMAIN PROTEINS. The species A. thaliana is used for experiments in classical plant genetics as well as molecular genetic studies in plant physiology, biochemistry, and development.
A plant homeotic protein involved in the development of stamens and carpels of Arabidopsis thaliana. It is a DNA-binding protein that contains the MADS-box domain. It is one of the four founder proteins that structurally define the superfamily of MADS DOMAIN PROTEINS.
