“…Modern highly productive cultivars of hexaploid crop wheat (Triticum aestivum) were developed from wild diploid and tetraploid wheat species and two species of the genus Aegilops [24]; therefore, the Aegilops genus is closely related to Triticum [25,26]. Wild relatives of common wheat are an ideal source of genes related to biotic and abiotic stress resistance and have a long history in wheat breeding, predominantly for improving resistance to heat and drought [26,27], salinity [28], high temperature [29], and cold [30,31]. Physiological and morphological acclimation traits tend to depend on the climate in the native habitat of the plant species [27,32].…”

Plants are subjected to unregulated water loss from their surface by cuticular transpiration. Therefore, specific morphophysiological changes may occur during leaf development to eliminate water loss. This study aimed to examine the cuticular transpiration of 23 winter wheat genotypes and their wild-growing predecessors of the genus Aegilops, which were divided into three groups to demonstrate their diversity. The genotypes were sown in autumn and grown in regular field trials at the Research Institute of Plant Production in Piešťany, Slovakia. Cuticular transpiration and growth parameters were analyzed in the postanthesis growth stage. Gravimetric measurement of residual water loss was performed on detached leaves with a precisely measured leaf area. The lowest nonproductive transpiration values were observed in modern wheat genotypes, while higher cuticular transpiration was observed in a group of landraces. Aegilops species generally showed the highest cuticular transpiration with increased water loss, but the total water loss per plot was low due to the low leaf area of the wild wheat relatives. Some of the growth parameters showed a good correlation with cuticular transpiration (e.g., dry mass per plant), but direct relationships between leaf traits and cuticular transpiration were not observed. This study identified a high diversity in cuticular resistance to water loss in wheat and Aegilops accessions of different origins. The potential of identifying and exploiting genetic resources with favorable cuticular transpiration in crop breeding is discussed.

“…tauschii accessions from northern and Central Iran by means of retroelement insertional polymorphisms generated using IRAP markers. The REMAP markers were used for molecular diversity analysis of 45 genotypes from four Aegilops species, and a high number of polymorphic bands (96.09% of polymorphism) with a mean PIC value of 0.25 was produced [ 57 ].…”

Background Aegilops tauschii Coss. as a donor of wheat D genome has an important role in wheat breeding programs. Genetic and phylogeographic diversity of 79 Ae. tauschii accessions collected from north and northwest of Iran were analyzed based on retroelement insertional polymorphisms using inter-retrotransposon amplified polymorphism (IRAP) and retrotransposon-microsatellite amplified polymorphism (REMAP) markers. Results In total, 306 and 151 polymorphic bands were amplified in IRAP and REMAP analyses, respectively. As a result, a high level of polymorphism was observed among the studied accessions as revealed by an average of 25.5 bands per primer/primer combination and mean PIC value of 0.47 in IRAP and an average of 25.16 bands per primer combination and mean PIC value of 0.47 in REMAP. Genetic relationships of the accessions were analyzed using distance- and model-based cluster analyses. Conclusion The result showed that genetic distance did not seem to be related to geographic distribution, and the accessions could be divided into three groups, which was further supported by principal coordinate analysis. These results on genetic diversity and population structure of Ae. tauschii in Iran should provide important knowledge on genetic resources and their applications in wheat breeding programs.

Honeybee (Apis mellifera L.) is a model organism, contributing signi cant effect on global ecology by pollination and examining due to its social behaviour. MethodsIn this study, barley-speci c Sukkula and Nikita retrotransposons were analysed using IRAP (Inter-Retrotransposon Ampli cation Polymorphism) marker technique, and the relationships between retrotransposon movements and development were also investigated in three different colonies of the Caucasian bee (Apis mellifera caucasica). Furthermore, transposon sequences belonging to Apis mellifera, Bombus terrestris, Triticum turgidum and Hordeum vulgare were also examined to gure out evolutionary relationships. ResultsFor this purpose, a queen bee, ve worker bees, and ve larvae from each colony were studied. Both retrotransposons were found in all samples in three colonies with different polymorphism ratios (0-100% for Nikita and 0-67% for Sukkula). We also determined polymorphisms in queen-worker (0-83% for Nikita, 0-63% for Sukkula), queen-larvae (0-83% for Nikita, 0-43% for Sukkula) and worker-larvae comparisons (0-100% for Nikita, 0-63% for Sukkula) in colonies. Moreover, close relationships among transposons found in plant and insect genomes as a result of in silico evaluations to verify experimental results. ConclusionThis work could be one of the rst studies to analyse plant-speci c retrotransposons' movements in honeybee genome. Results are expected to understand evolutionary relationships in terms of horizontal transfer of transposons among kingdoms.
