Tibetan hulless barley(Hordeum vulgare L. var. nudum. hook. f.) has been cultured as main cereal crops by the inhabitants on Tibetan plateau for thousands of year. Compared to the normal cultivated barley and all other plants within the genus Hordeum,the hulless barley has developed stronger endogenous resistance systems to survive and grow under the general environmental stresses in the Tibetan Plateau. However,little of the mechanism of these stress defense systems has been reported. The low temperature acclimation process but non-freezing temperatures would trigger rapid signaling events in target plants which often leads to the responding expression of cold-regulated genes,as well as their transcription factors,for an anticipation of the coming environmental freezing tolerance. In order to find out whether the circadian rhythmic expression profiles of clock genes in hulless barley,such as TOC1,CCA1,LHY,etc. and the cold responding genes,either CBF,LEA in ABA pathway or NHX,CBL and CIPK in non-ABA pathway are affected by the non-freezing low temperature stress,q PCR method was employed to detect the rhythmic expression patterns of those above-mentioned genes in time course hulless barley seedlings which had been stressed by non-freezing low temperatures under LL condition. The primary results demonstrated that in the control group(under 25°C),the expression profiles of the circadian clock genes showed robust circadian rhythmic,as well as which of those non-ABA pathway cold-stress responding genes displayed obvious circadian rhythmic profiles,while none of the stress responding genes′ expression involved in the ABA pathway were proved to be clock controlled. Under the low temperature(4°C) treated condition,the rhythmic expression patterns of most clock genes maintained their robust rhythmic though that of GI and LUX showed slight phase shifting and dimmed amplitudes. In terms of the stress responding genes in nonABA pathway,their expression profiles were severely
