Alien genes introgression and development of alien monosomic addition lines from a threatened species, Allium roylei Stearn, to Allium cepa L.

Establishment of a series of alien monosomic addition lines of Japanese bunching onion (Allium fistulosum L.) with extra chromosomes from shallot (A. cepa L. aggregatum group).

Forty one plants of alien monosomic addition lines of Allium fistulosum L. with extra chromosomes from A. cepa L. Aggregatum group (FF + nA) were produced through the second backcross of amphidiploids between these two species to A. fistulosum. Identification of the extra chromosomes in the 16 plants by elaborate karyotype analyses indicate that a complete series (eight different types) of the ...

Sterility in Allium Roylei Stearn – a Lesser Explored Taxon

Plants of Allium roylei Stearn, a threatened taxon of North – West Himalayas studied are complex translocation heterozygotes. Structural alterations imposed thereby on the chromosomes adversely affect the reproductive features of the species. Pollen grains formed share variable number of chromosomes ranging from 1 to 8 instead of the normal. This drastically acts down their siring potential by ...

Biochemical analyses of the antioxidative activity and chemical ingredients in eight different Allium alien monosomic addition lines.

We measured the antioxidant contents and antioxidative activities in eight Allium fistulosum-shallot monosomic addition lines (MAL; FF+1A-FF+8A). The high antioxidative activity lines (FF+2A and FF+6A) showed high polyphenol accumulation. These additional chromosomes (2A and 6A) would therefore have anonymous genes related to the upregulation of polyphenol production, the antioxidative activiti...

Potency of Allium sativum and Allium cepa Oils against Schistosoma

Introduction: It has been reported that garlic (Allium sativum) and onion (Allium cepa) are used all over the world in different diseases, such as infections, injuries, gastrointestinal dysfunctions and cardiovascular diseases. Therefore, our aim in this work was to study the ability of garlic and onion oils to offset the infectivity as well as the metabolic disturbances induced by Schistosoma ...
