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...

In order for rose plants to develop normally, one of the conditions is timely detection attacks damaging agents, an important place within which belongs phytopathogens Sphaerotheca Pannosa (Wallr.) Lev. Var. Rosae Woron and Diplocarpon Wolf. Quantifying effect attack pathogens pannosa rosae on monitored varieties, revealed changes in some biological failures related ratio length / width leaflet...

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-...
