Phytochromes
In addition, we are using the frog system to study size changes that occur during early development by preparing extracts from embryos at different stages. The fertilized egg is 1 mm in diameter in X. laevis, and undergoes rapid cleavages without growth so that the first ~4000 cells of the embryo are generated with minimal transcription or translation. I believe Xenopus will allow us to crack f...
متن کاملDistinct roles of GIGANTEA in promoting flowering and regulating circadian rhythms in Arabidopsis.
The circadian clock acts as the timekeeping mechanism in photoperiodism. In Arabidopsis thaliana, a circadian clock-controlled flowering pathway comprising the genes GIGANTEA (GI), CONSTANS (CO), and FLOWERING LOCUS T (FT) promotes flowering specifically under long days. Within this pathway, GI regulates circadian rhythms and flowering and acts earlier in the hierarchy than CO and FT, suggestin...
متن کاملOs-GIGANTEA confers robust diurnal rhythms on the global transcriptome of rice in the field.
The circadian clock controls physiological traits such as flowering time, photosynthesis, and growth in plants under laboratory conditions. Under natural field conditions, however, little is known about the significance of the circadian clock in plants. By time-course transcriptome analyses of rice (Oryza sativa) leaves, using a newly isolated rice circadian clock-related mutant carrying a null...
متن کاملPhytochromes from Agrobacterium fabrum.
Agrobacterium fabrum is a widely used model bacterium for gene transfer from pro- to eukaryote, for genetics and metabolism. The phytochrome system of Agrobacterium, encompassing the two phytochromes Agp1 and Agp2, has provided deep insight into phytochrome action in a bacterial organism. This review summarizes recent results on phytochrome evolution, phytochrome regulation of conjugation and p...
متن کاملTemporal Interactions between Cortical Rhythms
Multiple local neuronal circuits support different, discrete frequencies of network rhythm in neocortex. Relationships between different frequencies correspond to mechanisms designed to minimise interference, couple activity via stable phase interactions, and control the amplitude of one frequency relative to the phase of another. These mechanisms are proposed to form a framework for spectral i...
