Aegilops sharonensis, a wild relative of wheat, harbors diverse disease and insect resistance genes, making it a potentially excellent gene source for wheat improvement. In this study, we characterized and evaluated six wheat-A. sharonensis derivatives, which included three disomic additions, one disomic substitution + monotelosomic addition and two disomic substitution + disomic additions. A total of 51 PLUG markers were developed and used to allocate the A. sharonensis chromosomes in each of the six derivatives to Triticeae homoeologous groups. A set of cytogenetic markers specific for A. sharonensis chromosomes was established based on FISH using oligonucleotides as probes. Molecular cytogenetic marker analysis confirmed that these lines were a CS-A. sharonensis 2Ssh disomic addition, a 4Ssh disomic addition, a 4Ssh (4D) substitution + 5SshL monotelosomic addition, a 6Ssh disomic addition, a 4Ssh (4D) substitution + 6Ssh disomic addition and a 4Ssh (4D) substitution + 7Ssh disomic addition line, respectively. Disease resistance investigations showed that chromosome 7Ssh of A. sharonensis might harbor a new powdery mildew resistance gene, and therefore it has potential for use as resistance source for wheat breeding.

“…Hexaploid lines were selected through cytological control [4,5], and their cytological stability was repeatedly retested in succes sive generations [6,7]. The presence, number, and size of alien substitutions were determined through inves tigating the chromosomal configuration of pairing chromosomes in the F 1 hybrid under the conditions of maximum chromosome associations during meiosis I of pollen mother cells [6,8,9]. The homeologous dependence of chromosomes was determined, using biochemical markers specific to seven homeologous groups of the Triticeae chromosomes [2].…”

Permanent genetic variability in the introgressive lines and amphidiploids of Triticeae

The hybrid origin of an organism's genome has been regarded in recent years as the cause for a certain genetic instability inherent in such genomes. Using the model of amphidiploids and introgressive Aegilops wheat lines, evidence is given for confirming the facts of permanent alterations in their genomes, which were revealed at the phenotypic level in studies of morphological traits and biochemical character in successive generations of certain genotypes, as well as those of F 1 and F 2 hybrids. The actions of both trans posons and intrachromosomal rearrangements caused by the 4S sh gametocidal chromosome may be consid ered as the causes of such variability.

“…Introgression lines (ILs) Triticum aestivum / Aegilops sharonensis, T. aestivum / Ae. umbellulata, and T. aestivum / Amblyopyrum muticum were developed from crossing the genome-substitution amphidiploids Aurosis, Aurolata and Aurotica as a male parent with the winter cultivar of T. aestivum Aurora as a female parent (Zhirov and Ternovskaya 1984;Antonyuk and Ternovska, 2001;Antonyuk et al 2009). Some of the lines have dark glumes, which is more intense than glume color of their parents, T. aestivum Aurora, and the genome-substitution amphidiploids Aurosis (AABBS sh S sh ), Aurolata (AABBUU), and Aurotica (AABBTT) (Zhirov and Ternovskaya 1984;Antonyuk et al 2013).…”

Origin of black glume color in Triticum aestivum lines with introgressions from wheat wild relatives

et al. 2022

ABSTRACT Dark color of a glume in Triticinae is a known morphological marker with studied genetic control. However, the pigments that provide the color development, molecular basis of their biosynthesis, and mechanisms of its regulation are still unknown. Dark color of glumes is a common trait in the Triticum aestivum lines with alien introgressions. To find out the basis of this trait, we studied nature of the compounds that color the glumes by analyzing the total phenolic content (TPC) in the dark glumed introgression lines (ILs) and comparing it to their parents. TPC in the dark ILs was found to be higher than in their parents and in the light lines. All studied genotypes were screened for the expression of eight genes encoding the flavonoid biosynthesis pathway enzymes. Expression of three flavonoid genes in the pathway were changed in the ILs compared to their parents. Firstly, the expression of F3’H and FNS was absent in the lines with introgressions from Aegilops spp. The expression of three genes, F3’H, FLS, and FNS, was found to be altered in the light lines with introgressions from A. muticum. No expression of the F3’H was detected in the T. aestivum / A. muticum lines with light and dark plants, and the other genes of the pathway were found to be expressed at the parental levels. No correlation between the expression profiles and the phenotype was found in the T. aestivum / A. muticum lines. So we hypothesized that other undetected changes are present in these lines.
