Phylogenic analysis in Acacia senegal using AFLP molecular markers across the Gum Arabic Belt in Sudan

Abstract: Amplified fragment length polymorphism (AFLP) DNA markers were used to characterize the genetic diversity and relationships in gum Arabic tree (Acacia senegal) Twenty eight samples of Acacia senegal collected from populations distributed throughout the Gum Arabic belt were tested in comparison with samples of Acacia mellifera and Acacia leata Nine AFLP selective primer pair combinations generated a total of 433 amplification products with an average of 8918% detected polymorphisms Accessions showed the least variation was found within the A senegal accessions in contrast with mellifera and Acacia leata that presented the highest degree of polymorphism number According to the cluster analysis two main clusters were obtained in which A mellifera and A leata were placed in a separate group There were eight subgroups of A Senegal Three of the eight subgroups of A senegal were clustered according to geographical origin The variation within population might be correlated with abiotic factors of the environment

Feed for fish farming and production thereof

Abstract: PURPOSE:To produce a feed for fish farming, capable of preventing the degration or dispersion thereof and outflow of a fish meat extract, and having a low sinking ratio in seawater and high digestibility, by coating the surface of a cut fish or pelletized minced fish meat with a natural high polymer. CONSTITUTION:A cut fish or pelletized minced fish meat is dipped in an aqueous solution of one or two or more natural high polymers selected from gelatin, pectin, gum arabic, xanthan gum, sodium alginate, agar, KONJAK (devil's- tongue), carrageenan, etc. to coat the surface thereof with the above-mentioned natural high polymers.
