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)
The einkorn wheat mutant mvp-1 (maintained vegetative phase 1) has a non-flowering phenotype caused by deletions including, but not limited to, the genes CYS, PHYC, and VRN1. However, the impact of these deletions on global gene expression is still unknown. Transcriptome analysis showed that these deletions caused the upregulation of several(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)
Wheat is a major staple crop with broad adaptability to a wide range of environmental conditions. This adaptability involves several stress and developmentally responsive genes, in which microRNAs (miRNAs) have emerged as important regulatory factors. However, the currently used approaches to identify miRNAs in this polyploid complex system focus on(More)
MicroRNAs (miRNAs) are emerging as important post tran-scriptional regulators that may regulate key plant genes responsible for agronomic traits such as grain yield and stress tolerance. Several studies identified species and clades specific miRNA families associated with plant stress regulated genes. Here, we propose a novel resource that provides data(More)
