Earliness per se genes are those that regulate flowering time independently of vernalization and photoperiod, and are important for the fine tuning of flowering time and for the wide adaptation of wheat to different environments. The earliness per se locus Eps-A(m)1 was recently mapped within a 0.8 cM interval on chromosome 1A(m)L of diploid wheat Triticum monococcum L., and it was shown that i...

Doubled haploid (DH) populations are useful to scientists and breeders in both crop improvement and basic research. Current methods of producing DHs usually need in vitro culture for extracting haploids and chemical treatment for chromosome doubling. This report describes a simple method for synthesizing DHs (SynDH) especially for allopolyploid species by utilizing meiotic restitution genes. Th...

The present study aimed the evaluation of allelopathic effect of aqueous extract of coffee (Coffea arabica) against germination and radicle growth of Cicer arietinum and Triticum aestivum seeds. The extract at different concentrations was incubated in controlled conditions with the surface sterilized seeds of C. arietinum and T. aestivum and observed periodically for seed germination and radicl...

Intact protoplasts and chloroplasts have been isolated from mature flag leaves of wheat (Triticum aestivum L.). Both showed high rates of photosynthesis, the best of which equaled those observed in the parent tissue (greater than 150 micromoles O(2) per milligram chlorophyll per hour). The presence of ethylenediaminetetraacetate and an alkaline medium (pH 8.4) were required in the isolation and...

Prioritization and Identification of Candidate Genes Associated with Root Traits Under Salinity Stress in Bread Wheat (Triticum aestivum L.)

Homeologous wheat chromosome arms that differ by the presence or absence of a Nor locus or greatly differ in the numbers of copies of rRNA genes per Nor locus show conspicuous differences in the distribution of recombination. To assess directly the position effects of Nor loci on recombination across chromosome arms, a Triticum monococcum Nor9 haplotype was substituted for Triticum aestivum Nor...

This study investigated the formation and plant uptake of lipophilic metal-rhamnolipid complexes. Monorhamnosyl and dirhamnosyl rhamnolipids formed lipophilic complexes with copper (Cu), manganese (Mn), and zinc (Zn). Rhamnolipids significantly increased Zn absorption by Brassica napus var. Pinnacle roots in (65)Zn-spiked ice-cold solutions, compared with ZnSO4 alone. Therefore, rhamnolipid app...

The aim of this study was to compare the concentrations of five macroand fifteen microelements in the whole grain of spring lines of emmer, einkorn, spelt and two common wheat cultivars, all grown under identical environmental conditions. All elements were determined by ICP-SFMS analysis. The studied Triticum species differed significantly with respect to the concentrations of P, Mg, Zn, Fe, Mn...

Cereals represent the most important group of crops in the structure of plant production from the economic, agronomic and consumer point of view. Spelt wheat (Triticum spelta L.) is an ancient bread cereal related to wheat (Triticum aestivum L.) that has been cultivated for hundreds of years, and that is now being rediscovered in Europe and North America. Spelt is generating increasing interest...
