    Complete mitochondrial genome of the Algerian honeybee, Apis mellifera intermissa (Hymenoptera: Apidae)
    (Taylor and Francis Online, 2016) Hu, Peng; Lu, Zhi-Xiang; Jamal Haddad, Nizar; Adjlane, Noureddine; Loucif-Ayad, Wahida; Yong-Zhi, Wang; Zhang, Ai-Ling
    In this study, the complete mitochondrial genome sequence of Algerian honeybee,Apismellifera intermissa, is analyzed for the first time. The results show that this genome is 16,336 bpin length, and contains 13 protein-coding genes, 22 transfer RNA genes, 2 ribosomal RNAgenes, and 1 control region (D-loop). The overall base composition is A (43.2%), C (9.8%),G (5.6%), and T (41.4%), so the percentage of A and T (84.6%) is considerably higher than that ofG and C. All the genes are encoded on H-strand, except for four subunit genes (ND1,ND4,ND4L,andND5), two rRNA genes (12Sand16S rRNA), and eight tRNA genes. The completemitochondrial genome sequence reported here would be useful for further phylogeneticanalysis and conservation genetic studies inA.m.intermissa.

    Distribution and variability of deformed wing virusof honeybees (Apis mellifera) in the Middle East and NorthAfrica
    (wiley, 2015) Jamal Haddad, Nizar; Adjlane, Noureddine; Al-Shagour, Banan; Loucif-Ayad, Wahida; El-Niweiri, Mogbel A. A.; Anaswah, Eman; Abu Hammour, Wafaa; El-Obeid, Dany; Albaba, Imad; Shebl, Mohamed; Abdulhusien, Sehen Almaleky; Nasher, Abdullah; Nagara, Walid; Bergigui, Mohamed Fouad; Ya ̃nez, Orlando; de Miranda, Joachim R.
    Three hundred and eleven honeybee samples from 12 countries in the Mid-dle East and North Africa (MENA) (Jordan, Lebanon, Syria, Iraq, Egypt, Libya, Tunisia,Algeria, Morocco, Yemen, Palestine, and Sudan) were analyzed for the presence of de-formed wing virus (DWV). The prevalence of DWV throughout the MENA region waspervasive, but variable. The highest prevalence was found in Lebanon and Syria, withprevalence dropping in Palestine, Jordan, and Egypt before increasing slightly movingwestwards to Algeria and Morocco Phylogenetic analysis of a 194 nucleotide section ofthe DWV Lp gene did not identify any significant phylogenetic resolution among thesamples, although the sequences did show consistent regional clustering, including an in-teresting geographic gradient from Morocco through North Africa to Jordan and Syria. Thesequences revealed several clear variability hotspots in the deduced amino acid sequence,which furthermore showed some patterns of regional identity. Furthermore, the sequencevariants from the Middle East and North Africa appear more numerous and diverse thanthose from Europe

    Draft genome sequence of the algerian bee apis mellifera intermissa
    (Elsevier, 2015) Haddad, Nizar Jamal; Loucif-Ayad, Wahida; Adjlane, Noureddine; Saini, Deepti; Manchiganti, Rushiraj; Krishnamurthy, Venkatesh; AlShagoor, Banan; Batainh, Ahmed Mahmud; Mugasimangalam, Raja
    Apis mellifera intermissa is the native honeybee subspecies of Algeria. A. m. intermissa occurs in Tunisia, Algeria and Morocco, between the Atlas and the Mediterranean and Atlantic coasts. This bee is very important due to its high ability to adapt to great variations in climatic conditions and due to its preferable cleaning behavior. Here we report the draft genome sequence of this honey bee, its Whole Genome Shotgun project has been deposited at DDBJ/EMBL/GenBank under the accession JSUV00000000. The 240-Mb genome is being annotated and analyzed. Comparison with the genome of other Apis mellifera sub-species promises to yield insights into the evolution of adaptations to high temperature and resistance to Varroa parasite infestation

    Mitochondrial genome of the North AfricanSahara Honeybee, Apis mellifera sahariensis(Hymenoptera: Apidae)
    (Taylor and Francis Online, 2017) Nizar, Haddad; Adjlane, Noureddine; Loucif-Ayad, Wahida; Dash, Abhinandita; Naganeeswaran, S.; Rajashekar, Balaji; Al-Nakeeb, Kosai; Thomas Sicheritz, Ponten
    We present the complete mitochondrial genome of honey bee subspecies, Apis mellifera sahariensis (Apidae) belonging to the African lineage. The assembled circular genome has a length of 16,569 bp which comprises 13 protein coding genes, 22 transfer RNA genes, two ribosomal RNA genes, and AT rich region
