Four LMW-m and one novel chimeric (between LMW-i and LMW-m types) low-molecular-weight glutenin subunit (LMW-GS) genes from Aegilops neglecta (UUMM), Ae. kotschyi (UUSS), and Ae. juvenalis (DDMMUU) were isolated and characterized. Sequence structures showed that the 4 LMW-m-type genes, assigned to the M genome of Ae. neglecta, displayed a high homology with those from hexaploid common wheat. Th...

Gum and resin bearing tree species were one of the very important resources in Ethiopia. Particularly, Borana pastoralists used these as a source income generation for their livelihoods. However, resource was declining over time due to different natural human made problems. Therefore, it is study its future sustainability through soil seed bank, germinations, vegetative propagations analyzing r...

The study was aimed at evaluating the antioxidant activity of hydroalcoholic solution extracts of Urtica dioica L. (UD), Malva neglecta Wallr. (MN) plants and their mixture. In this study, flower (UDF), root (UDR), seed (UDS) and leaf (UDL) parts of UD and flower (MNF) and leaf (MNL) parts of MN were used. The antioxidant properties of hydroalcoholic extracts and their mixture were evaluated us...

We describe and delimit with integrative taxonomy the new springtail species Desoria calderonis sp. nov. (Collembola: Isotomidae). This cryophilic is strictly linked to supraglacial stony debris of isolated Calderone glacier (Central Apennines, Italy), one southernmost glaciers Europe. could belong nivalis-complex, a group European mountain included in violacea-group. Genetic analysis (COI mtDN...

Aegilops columnaris Zhuk. is tetraploid grass species (2n = 4x 28, UcUcXcXc) closely related to Ae. neglecta and growing in Western Asia a western part of the Fertile Crescent. Genetic diversity was assessed using C-banding, FISH, nuclear chloroplast (cp) DNA analyses, gliadin electrophoresis. Cytogenetically subdivided into two groups, C-I C-II, showing different karyotype structure, FISH patt...

Phacelia scopulina var. submutica (Debeque phacelia) and Astragalus debequaeus (Debeque milkvetch) in Western Colorado

The classification of petrels (Pterodroma spp.) from Round Island, near Mauritius in the Indian Ocean, has confounded researchers since their discovery in 1948. In this study we investigate the relationships between Round Island petrels and their closest relatives using evidence from mitochondrial DNA sequence data and ectoparasites. Far from providing clear delimitation of species boundaries, ...

The allohexaploid Aegilops species (2n = 6x = 42), Ae. neglecta 6x (UUXtXtNN), Ae. juvenalis (DcDcXcXcUU), and Ae. vavilovii (DcDcXcXcSsSs) regularly form bivalents at metaphase I. However, in Ae. crassa 6x (DcDcXcXcDD) 0.27 quadrivalents per cell were observed probably as a consequence of the partial homology displayed by the D and Dc genomes. Likewise, the synthetic amphiploid Ae. ventricosa-...
