Abstract Goatgrasses with U‐ and M‐genomes are important sources of new alleles for wheat breeding to maintain yield quality under extreme conditions. However, the introgression beneficial traits from wild Aegilops species into has been limited by poor knowledge their genomes scarcity molecular tools. Here, we present first linkage map allotetraploid biuncialis Vis., developed using 224 F 2 individuals derived a cross between MvGB382 MvGB642 accessions. The comprises 5663 DArTseq markers...
Abstract Wheat-rye T1BL.1RS translocation is widespread worldwide as the genes on 1RS arm have positive effect stress resistance, grain yield and adaptation ability of wheat. Nowadays, wheat cultivars become susceptible to rust diseases because monophyletic (‘Petkus’) origin 1RS. Here we report discuss production detailed investigation a new line carrying with widened genetic base originating from Secale cereanum . Line ‘179’ exhibited improved spike morphology traits, resistance against...
The annual goatgrass, Aegilops biuncialis is a rich source of genes with considerable agronomic value. This genetic potential can be exploited for wheat improvement through interspecific hybridization to increase stress resistance, grain quality and adaptability. However, the low throughput cytogenetic selection hampers development alien introgressions. Using sequence flow-sorted chromosomes diploid progenitors, present study enabled chromosome-specific markers. In total, 482 PCR markers...
Understanding the genetic diversity of Aegilops biuncialis, a valuable source agronomical useful genes, may significantly facilitate introgression breeding wheat. The and population structure 86 Ae. biuncialis genotypes were investigated by 32700 DArT markers with simultaneous application three statistical methods- neighbor-joining clustering, Principal Coordinate Analysis, Bayesian approach to classification. collection accessions was divided into five groups that correlated well their...
Effective utilization of genetic diversity in wild relatives to improve wheat requires recombination between and alien chromosomes. However, this is suppressed by the Pairing homoeologous gene, Ph1, on long arm chromosome 5B. A deletion mutant Ph1 locus (ph1b) has been used widely induce × hybrids. original ph1b mutation, developed Chinese Spring (CS) background poor agronomic performance. Hence, introgression lines are first backcrossed with adapted genotypes after step, segments introduced...
Grain dietary fiber content is an important health-promoting trait of bread wheat. A dominant component wheat the cell wall polysaccharide arabinoxylan and goatgrass Aegilops biuncialis has high β-glucan content, which makes it attractive gene source to develop lines with modified composition. In order support introgression breeding, this work examined genetic variability in grain β-glucan, pentosan, protein a collection Ae. biuncialis. large variation edible was revealed, reflecting origin...
Abstract High molecular weight glutenin subunits (HMW GS) represent an important fraction of endosperm-specific seed-storage proteins that provide elasticity to bread dough. Previously, the second cis -regulatory module (CRM2) was found be one most conserved part HMW GS promoters, which indicated its pre-eminent role in their gene regulation. Here, we observed deletion CRM2 from promoters Bx7 and By8 genes increased leakage transient expression wheat leaf tissue. The effect a VP1, Myb...
Wild wheat relative Aegilops biuncialis offers valuable traits for crop improvement through interspecific hybridization. However, gene transfer from has been hampered by difficulties in detecting introgressed U
Abstract The perennial Secale cereanum cultivar ‘Kriszta’ is an artificial hybrid of S. cereale and strictum ssp. anatolicum . From the cross between wheat line Mv9kr1 ‘Kriszta’, which aimed transfer beneficial traits from rye to wheat, numerous translocation lines have been produced. For identification translocated chromosomes, unambiguous differentiation chromosome arms essential. its short using conventional FISH probes easy, but because their similar hybridization patterns, long cannot...

Cultivated and wild species of the genus rye (
GBS read coverage analysis identified a Robertsonian chromosome from two Thinopyrum subgenomes in wheat, conferring leaf and stripe rust resistance, drought tolerance, maintaining yield stability. Agropyron glael (GLAEL), intermedium × Th. ponticum hybrid, serves as valuable genetic resource for wheat improvement. Despite its potential, limited knowledge of structure homoeologous relationships with hexaploid (Triticum aestivum) has restricted the full exploitation GLAEL's diversity breeding...
