Arabidopsis thalianaThe Alc-inducible system is a simple, yet effective, "gene switch" that can be used to transiently induce gene expression in Arabidopsis. Here we provide a protocol for using the Alc-inducible system to give a pulse in expression of a circadian clock gene in transgenic ...
This review examines the roles that alleles of circadian clock genes have played in domestication and improvement of crop plants. The focus here is on three groups of circadian clock genes essential to clock function in Arabidopsis thaliana: PSEUDO-RESPONSE REGULATORs, GIGANTEA, and the evening ...
Genetic studies in the model plant Arabidopsis thaliana have revealed that the circadian clock is composed of interacting repressing loops. The core loop consists of the morning loop genes, LATE ELONGATED HYPOCOTYL (LHY) and CIRCADIAN CLOCK-ASSOCIATED 1 (CCA1), which repress the evening loop gene...
these clock genes have been shown to cycle in phase with their Arabidopsis counterparts, consistent with the conservation of clock architecture among plants. More recently, the availability of multiple plant genomes has permitted a more systematic and comprehensive taxonomic survey ...
The genetic circuit underlying the Arabidopsis circadian oscillator was initially proposed to function through the reciprocal regulation between the CIRCADIAN CLOCK ASSOCIATED 1 (CCA1), LATE ELONGATED HYPOCOTYL (LHY), and TIMING OF CAB EXPRESSION 1 (TOC1) genes 2, 3, 4. The morning-expressed CCA1...
Arabidopsis, such as rhythmicity of growth (Matos et al.2014; Poiré et al.2010) and different versions of the clock operating in different parts of the plant (Endo et al.2014; James et al.2008). Understanding the evolutionary relationships among clock genes will aid the development of clock...
Sorghum genes homologous to the Arabidopsis morning‐phased circadian clock genes , , and were downregulated and evening‐phased genes such as , and were upregulated in young internodes in response to shade. We hypothesize that a change in the function or patterns of expression of the circadian ...

Mathematical modelling suggests that the direct effect of HY5 on the apparently non-responsive clock genes could be masked by feed-back from the clock gene network. We conclude that the information on the ratio of blue and red components of the white light spectrum is decoded and relayed to ...
