Around 14 distinct virus species-complexes have been detected in honeybees, each with one or more strains sub-species. Here we present the initial characterization of an entirely new species-complex discovered honeybee (Apis mellifera L.) and varroa mite (Varroa destructor) samples from Europe USA. The has a naturally poly-adenylated RNA genome about 6500 nucleotides organization sequence similar to Tymoviridae (Tymovirales; Tymoviridae), predominantly plant-infecting family. Literature...
In 1977, a sample of diseased adult honeybees (Apis mellifera) from Egypt was found to contain large amounts previously unknown virus, bee which subsequently shown be serologically related deformed wing virus (DWV). By sequencing the original isolate, we demonstrate that is in fact fourth unique, major variant DWV (DWV-D): more closely DWV-C than either DWV-A or DWV-B. and DWV-B are most common variants worldwide due their close relationship transmission by Varroa destructor. However, could...
Abstract The Dromedary camel has a remarkable history amongst cultures across Asia and northern Africa, serving multiple purposes ranging from providing milk, textiles, racing, acting as pack animals. Recent genetic studies have revealed that many dromedaries are genetically homogenous, indicating they do not represent different breeds, advocating for ‘type’ over ‘breed’. In this study, we leveraged whole genome sequencing (WGS) to sequence 15 Jordanian Alia camels the first time, alongside...
Novel transmission routes can allow infectious diseases to spread, often with devastating consequences. Ectoparasitic varroa mites vector a diversity of RNA viruses, having switched hosts from the eastern western honey bees (Apis cerana Apis mellifera). They provide an opportunity explore how novel shape disease epidemiology. As principal driver spread deformed wing viruses (mainly DWV-A and DWV-B), infestation has also driven global bee health declines. The more virulent DWV-B strain been...
The effect of two training systems (Central Leader with branch pruning versus Centrifugal Training minimal pruning, i.e., removal fruiting laterals only) on canopy structure and light interception was analyzed in three architecturally contrasting apple (Malus domestica Borkh.) cultivars: 'Scarletspur Delicious' (Type II); 'Golden III); 'Granny Smith' IV). Trees were 3D-digitized at the shoot scale 2004 2005 harvests. Shoots separated according to length (short long) type (fruiting...
Insecticides can affect development and survival of non-target beneficial arthropods like honey bees (Apis mellifera L.).Thiamethoxam spinosad are widely used as pesticides in agriculture but they have become an important concern for beekeepers researchers focusing on bee health; multiple reports stressed adverse effects bees, notably bees.The present study aims to evaluate the impact these two insecticides HPGs Apis intermissa a native African subspecies Algeria.Newly emerged workers were...
This study aimed to develop novel SSR markers in tomato. Several BAC clones along chromosome 3 tomato were selected based on their content. The criteria was the availability of genes, either directly or indirectly related stress response (drought, salinity, and heat) A total 20 silico developed 96 important nearby genes identified. identified represent different involved plant growth development biotic abiotic tolerance. assessed using landraces. 29 determinate semi-determinate local...
ABSTRACT The effect of different irrigation methods (sprinkler, surface, surface-drip, and subsurface-drip) using treated wastewater, on alfalfa yield quantity quality, was studied under semi-arid conditions. Randomized complete block design considering 5 × m plots replicated four times. Applied water based the Penman–Monteith equation FAO Cropwat software accounting for efficiencies used systems. Surface gave highest fresh without significant difference compared to subsurface-drip. Average...

Apis mellifera syriaca exhibits a high degree of tolerance to pests and pathogens including varroa mites. This native honey bee subspecies Jordan expresses behavioral adaptations temperature dry seasons typical the region. However, persistent imports commercial breeder lines are endangering local population. study reports use next-generation sequencing (NGS) technology A. m. genome identify genetic factors possibly contributing toward mite resistance other favorable traits. We obtained total...
In this study, the complete mitochondrial genome sequence of Algerian honeybee, Apis mellifera intermissa, is analyzed for first time. The results show that 16,336 bp in length, and contains 13 protein-coding genes, 22 transfer RNA 2 ribosomal 1 control region (D-loop). overall base composition A (43.2%), C (9.8%), G (5.6%), T (41.4%), so percentage (84.6%) considerably higher than C. All genes are encoded on H-strand, except four subunit (ND1, ND4, ND4L, ND5), two rRNA (12S 16S rRNA), eight...
Three hundred and eleven honeybee samples from 12 countries in the Middle East North Africa (MENA) (Jordan, Lebanon, Syria, Iraq, Egypt, Libya, Tunisia, Algeria, Morocco, Yemen, Palestine, Sudan) were analyzed for presence of deformed wing virus (DWV). The prevalence DWV throughout MENA region was pervasive, but variable. highest found Lebanon with dropping Jordan, Egypt before increasing slightly moving westwards to Algeria Morocco Phylogenetic analysis a 194 nucleotide section Lp gene did...
AbstractThe mitochondrial genome sequence of Levant Region honeybee, Apis mellifera syriaca, is analyzed and presented for the public first time. The this honeybee 15,428 bp in its length, containing 13 protein-coding genes, 22 transfer RNA genes 2 ribosomal genes. overall base composition A (42.88%), C (9.97%), G (5.85%), T (41.3%), percentage being higher than that C. Percentage non-ATGC characters 0.007. All are encoded on H-strand, except four subunit (ND1, ND4, ND4L, ND5), two rRNA...
The complete mitochondrial genome of the western honey bee subspecies Apis mellifera lamarckii was sequenced. This is 16,589 bp in length with 37 classical eukaryotic genes and an A + T-rich region. Gene directions arrangements are similar to those other mitogenomes. Seven begin ATT, four ATG, two ATA (none ATC) all terminate TAA. Four encoded on heavy strand nine light strand. All 22 tRNA genes, ranging from 66 80 bp, have a typical cloverleaf structure. phylogenetic tree showed that A.m....
Background and AimsDemography spatial distribution of shoots are rarely studied on pruned trees. The present 2-year study deals with the effect pruning strategies shoot demography development, consequences leaf area in three architecturally contrasted — from type II to IV apple cultivars: 'Scarletspur Delicious', 'Golden Delicious' 'Granny Smith'.
Honeybees, in addition to their production of honey, pollinate the flowers fruit trees and other crops. Any threat them, whether from pesticides, herbicides or diseases, therefore pose serious consequences not only for beekeeping, but also agriculture general. For several years, many beekeepers Algeria have reported deaths apiaries. At present, we lack hard data on causes such mortality. In order provide some answers this problem, conducted a field study with mid-northern Algeria. This is...
