Apis mellifera L. is native to Europe, Africa, and Asia (including Saudi Arabia, Iran and the Ural mountains of Russia). It is currently widely distributed across the world due to multiple migrations and introductions (Ruttner, 1988). Apis mellifera includes about two dozen subspecies that are present in different regions of the world. These subspecies have been classified into five main lineag...

Dart, P. J. (University of Sydney, Sydney, Australia), and F. V. Mercer. Fine structure of bacteroids in root nodules of Vigna sinensis, Acacia longifolia, Viminaria juncea, and Lupinus angustifolius. J. Bacteriol. 91:1314-1319.-In nodules of Vigna sinensis, Acacia longifolia, and Viminaria juncea, membrane envelopes enclose groups of bacteroids. The bacteroids often contain inclusion granules ...

Unlike most other insects, annotated genomic data suggest that Apis mellifera has two homologous copies of the cytoplasmic gene HSP90. In this study, we did a phylogenetic analysis on these two copies with some other insects HSP90 genes, and we also manipulated a reverse transcript (RT)-PCR to find all the putative transcripts for both copies. Phylogenetic analysis indicates that A. mellifera p...

The western honeybee, Apis mellifera is a prominent model organism in the field of sociogenomics and a recent upgrade substantially improved annotations of the reference genome. Nevertheless, genome assemblies based on short-sequencing reads suffer from problems in regions comprising e.g. multi-copy genes. We used single-molecule nanopore-based sequencing with extensive read-lengths to reconstr...

The leaves of Acacia nilotica (L.) Delile was extracted with methanol and aqueous medium and studied for in vitro antimicrobial property. The methanol extract was found to be most active against all the bacterial species tested except S.aureus. Active methanol extract was further studied for HPTLC fingerprint and by phytochemical analysis. HPTLC analysis confirmed segregation of four individual...

The adsorption technique using chemically treated powder of bark of Acacia arabica was applied for the removal of toxic heavy metals from polluted waste water. The extent of adsorption found to be dependent on the pH and the time of contact. The adsorbent is effective for the quantitative removal of various toxic metals from the contaminated aqueous sample. The method is quite feasible, economi...

b a ckground: the varroa destructor mite is considered as a major pest of honey bees apis mellifera . the rapid spread of varroa mites among bee colonies may be due to several factors, including drifting of infested bees, movement of bee swarms, and robbing of weakened colonies. disease spread and predisposing the infested bees to other diseases lead to high economic losses in beekeeping indust...
