Most temperate plants tolerate both chilling and freezing temperatures whereas many species from tropical regions suffer chilling injury when exposed to temperatures slightly above freezing. Cold acclimation induces the expression of cold-regulated genes needed to protect plants against freezing stress. This induction is mediated, in part, by the CBF(More)
The transition to flowering in winter wheat requires prolonged exposure to low temperature, a process called vernalization. This process is regulated by a genetic pathway that involves at least three genes, Triticum aestivum VERNALIZATION 1 (TaVRN1), Triticum aestivum VERNALIZATION 2 (TaVRN2) and Triticum aestivum FLOWERING LOCUS T-like 1 (TaFT1). These(More)
The vernalization gene 2 (VRN2), is a major flowering repressor in temperate cereals that is regulated by low temperature and photoperiod. Here we show that the gene from Triticum aestivum (TaVRN2) is also regulated by salt, heat shock, dehydration, wounding and abscissic acid. Promoter analysis indicates that TaVRN2 regulatory region possesses all the(More)
Al tolerance is one of the most important trait for worldwide crop production. Using microarrays, we previously identified a transcription factor belonging to the C2H2 zinc finger protein (ZFP) family associated with Al tolerance in wheat (Houde and Diallo, BMC Genomics 9:400, 2008). The current work aimed to identify specific members of the C2H2 ZFP family(More)
