Project

Insect Photoperiodic Timer (GA17-01003S)

Photoperiodic timer enables animals to anticipate and thus survive adverse in temperate regions. Yet the basis of photoperiodic sensing remains elusive, mostly due to the lack of suitable genetic models expressing photoperiod

Effect of photoperiod and light stimuli on the functional state of the mammalian circadian clock (GA309/97/0512)

, i.e. on photoperiod; memory on the photoperiod might be stored directly in the SCN whether and how is the SCN pacemaker actually modulated by photoperiod. The following, affected by the photoperiod?; ii/ Does the...

The role of the circadian clock genes in photoperiodic time measurement (GP204/02/P008)

There is little knowledge about molecular components of the photoperiodic time that some components of circadian system may function in photoperiodic system with unknown photoperiodic system of closely related Chymomyza cos...

Role of melatonin and calcium in plant photoperiodism (ME 056)

This project investigates the mechanistic basis for photoperiodic time measurement in higher plants. The experimental goals are: (a) to measure the profiles of melatonin content and of cytosolic free calcium under different L:D cycles ph...

Molecular links between cirvadian and photoperiodic clocks in insects (GA206/05/2085)

unknown, physiological nature of the insect photoperiodism: May the known molecular elements of insect circadian clocks serve as functional parts of a photoperiodic clock system? The photoperiodic clocks enable insects to ...

Pathways connecting the perception of photoperiod to the response of endocrine glands in diapause, cold acclimation and rhythms (ME 169)

Photoperiod is used by insects as the most precise environmental signal for seasonal adaptations, such as developmental arrest and resistance to climatic stress. The photoperiodic information, received by eyes or central brain, is p...

Molecular and genetic study of Pyrrhocoris apterus photoperiodic clock (GP204/08/P579)

Although seasonal clocks are widespread in animals, their molecular mechanism is not understood. The key reason for this is the absence of solid photoperiodic phenotype in typical genetic model organisms. Therefore we will apply genetic meth...
