Identification, Structural and Functional Characterization of Dormancy Regulator Genes in Apricot ( L.).

In the present study, we identified and characterized the apricot ( L.) homologs of three dormancy-related genes, namely the (), () and genes. All highly conserved structural motifs and the 3D model of the DNA-binding domain indicate an unimpaired DNA-binding ability of CBF1.

Genome-wide association study and genetic diversity analysis on nitrogen use efficiency in a Central European winter wheat (Triticum aestivum L.) collection.

To satisfy future demands, the increase of wheat (Triticum aestivum L.) yield is inevitable. Simultaneously, maintaining high crop productivity and efficient use of nutrients, especially nitrogen use efficiency (NUE), are essential for sustainable agriculture.

Circadian and Light Regulated Expression of CBFs and their Upstream Signalling Genes in Barley.

CBF (C-repeat binding factor) transcription factors show high expression levels in response to cold; moreover, they play a key regulatory role in cold acclimation processes. Recently, however, more and more information has led to the conclusion that, apart from cold, light-including its spectra-also has a crucial role in regulating expression. Earlier, studies established that the expression patterns of some of these regulatory genes follow circadian rhythms.

Light and Temperature Signalling at the Level of Gene Expression in Wheat and Barley.

The wheat and barley genes have been newly defined as key components of the light quality-dependent regulation of the freezing tolerance by the integration of phytochrome-mediated light and temperature signals. To further investigate the wavelength dependence of light-induced expression in cereals, we carried out a detailed study using monochromatic light treatments at an inductive and a non-inductive temperature. Transcript levels of gene in winter wheat Cheyenne, winter einkorn G3116 and winter barley Nure genotypes were monitored.

The expression of genes at locus is associated with the level of frost tolerance in Bulgarian winter wheat cultivars.

The regulation of the majority of cold-regulated genes in plants is mediated by () transcription factor family. Natural differences in frost tolerance (FT) of wheat have been mapped to the () locus on chromosome group 5 and are associated with variation in threshold induction temperatures and/or transcript levels of genes. This study used real-time reverse-transcription polymerase chain reaction (qRT-PCR) to compare the relative expression levels of four genes ( and ) in crown tissue of two Bulgarian hexaploid winter wheat cultivars (Milena and Russalka) with distinct levels of low-temperature (LT) tolerance but same vernalization requirement, and the spring cultivar Chinese Spring.
