“…Also, sequence and structural of heat shock protein26 (HSP26) showed variations among various wheat progenitor as well as non-progenitor species. Variations included chromosome locations, copy number, single nucleotide polymorphism (SNPs), indels (Suneja et al, 2019). Variations revealed that positive selection during wheat evolution and the common ancestor of HSP26 among plants (Suneja et al, 2019).…”

Hexaploid wheat (Triticum aestivum, AABBDD) had developed from tetraploid and diploid progenitors with different genomic background. During evolution, changes in genome organization, gene expression, and genomic interactions occur. Real time PCR was employed to disclose changes in gene expression of three abiotic induced genes (DREB2, NAC6D, HSP17) in T. aestivum and four of its progenitors which had contributed in its development including Triticum turgidum (AABB), Triticum monococcum (AA), Aegilops spltoides (BB), and Aegilops taushii (DD) with different ploidy levels. Results showed that the three genes presented wide variations between T. aestivum and its progenitors as well as among its progenitors. Results suggested that T. aestivum could have inherited the high expression pattern of DREB2 from its progenitor A. speltoids, inherited its expression pattern of NAC6D form T. turgidum and/or A. taushii. The high expression pattern of HSP17 in T. aestivum could have been inherited from A. speltoides and/or T. turgidum. The obtained results support the notion that wheat progenitors have contributed in the gene expression profile of the hexaploid wheat. Results of this study will help detection of important genes in wheat progenitors that could be introduced into breeding programs for devolving new wheat varieties with desired characteristics.

Significance of the Diversification of Wheat Species for the Assembly and Functioning of the Root-Associated Microbiome

Wheat, one of the major crops in the world, has had a complex history that includes genomic hybridizations between Triticum and Aegilops species and several domestication events, which resulted in various wild and domesticated species (especially Triticum aestivum and Triticum durum), many of them still existing today. The large body of information available on wheat-microbe interactions, however, was mostly obtained without considering the importance of wheat evolutionary history and its consequences for wheat microbial ecology. This review addresses our current understanding of the microbiome of wheat root and rhizosphere in light of the information available on pre- and post-domestication wheat history, including differences between wild and domesticated wheats, ancient and modern types of cultivars as well as individual cultivars within a given wheat species. This analysis highlighted two major trends. First, most data deal with the taxonomic diversity rather than the microbial functioning of root-associated wheat microbiota, with so far a bias toward bacteria and mycorrhizal fungi that will progressively attenuate thanks to the inclusion of markers encompassing other micro-eukaryotes and archaea. Second, the comparison of wheat genotypes has mostly focused on the comparison of T. aestivum cultivars, sometimes with little consideration for their particular genetic and physiological traits. It is expected that the development of current sequencing technologies will enable to revisit the diversity of the wheat microbiome. This will provide a renewed opportunity to better understand the significance of wheat evolutionary history, and also to obtain the baseline information needed to develop microbiome-based breeding strategies for sustainable wheat farming.
