Genome-wide analysis of the heat shock transcription factor family in Triticum urartu and Aegilops tauschii
Heat shock proteins (Hsps) are believed to play essential roles in developmental processes and in responses to heat stress. Heat shock transcription factors (Hsfs) are important Hsp regulators, but their functions are poorly understood, especially in wheat. In this study, a comprehensive bioinformatics analysis was conducted in wheat A and D genome donors, Triticum urartu and Aegilops tauschii,...
متن کاملIron deficiency in barley plants: phytosiderophore release, iron translocation, and DNA methylation
All living organisms require iron (Fe) to carry out many crucial metabolic pathways. Despite its high concentrations in the geosphere, Fe bio-availability to plant roots can be very scarce. To cope with Fe shortage, plants can activate different strategies. For these reasons, we investigated Fe deficient Hordeum vulgare L. plants by monitoring growth, phytosiderophores (PS) release, iron conten...
متن کاملDissecting miRNAs in Wheat D Genome Progenitor, Aegilops tauschii
As the post-transcriptional regulators of gene expression, microRNAs or miRNAs comprise an integral part of understanding how genomes function. Although miRNAs have been a major focus of recent efforts, miRNA research is still in its infancy in most plant species. Aegilops tauschii, the D genome progenitor of bread wheat, is a wild diploid grass exhibiting remarkable population diversity. Due t...
متن کاملResponses of plants to iron, zinc and copper deficiencies.
Iron, copper and zinc are essential metals for cell metabolism. Plants have evolved different schemes to efficiently mobilize low-solubility nutrients such as metals from their environment and to transport them between organs. In this review we highlight the divergences and convergences of the iron, copper and zinc uptake, transport and homoeostatic pathways.
متن کاملMolecular mapping of segregation distortion loci in Aegilops tauschii.
Distorted segregation ratios of genetic markers are often observed in progeny of inter- and intraspecific hybrids and may result from competition among gametes or from abortion of the gamete or zygote. In this study, 194 markers mapped in an Aegilops tauschii F2 population were surveyed for distorted segregation ratios. Region(s) with skewed segregation ratios were detected on chromosomes 1D, 3...
