The present work aimed at study genetic diversity and the sources of molecular variation between the individual cloves of two garlic clones with different molecular markers, RAPD and SSR. Three bulbs of two garlic clones (Egaseed1 and Balady) were germinated (three individual cloves of each bulb). The total genomic DNA was extracted from the young leaves. Ten RAPD and fifteen SSR primers were used and the data were statistically analyzed. Fifty-seven bands (including 4 unique and 53 polymorphic) were totally generated and there were no monomorphic bands from ten RAPD primers. Two unique bands were detected with KO3 and KO6 primers (433 and 417 bp, respectively), likewise, two unique bands of 124 and 188 bp were detected with K10 RAPD primer in Egaseed1 clone. Thirteen SSR primers produced 45 DNA fragments. Out of them, 12 were monomorphic and the remaining were polymorphic. Different molecular markers could be used to evaluate genetic diversity and confirm the molecular differences between the cloves derived from the same bulb and the differentiated nature of garlic. In addition, it defines the importance of using molecular markers to evaluate different garlic clones.
The relationships of 12 species in six genera in the tribe Anthemideae of the Asteraceae such as Achillea santolina, A. fragrantissima, Anacyclus monanthos, Cotula anthemoids, C. barbata, C. cinerea, Glebionis coronaria var. discolor, Matricaria recutita and M. aurea collected in different localities in Egypt and have been addressed based on polymophism in ITS sequence. Phylogenetic relationships were constructed using bioinformatic tools based on molecular data of ITS sequence. Studied taxa showed cryptic differences in ITS and thus, they could be distinctly separated from the other close relatives of the genera in the tribe Anthemideae.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
