...tigate the most suitable insertion site for optimal expression of a foreign gene without compromising the replication of the Newcastle disease virus. Recently, inserting a green fluorescent protein (GFP) gene upstream from the GE sequences of the viral genes and subsequent quantitative measurements of the GFP fluorescence intensity, we have concluded that the P and M junction region is the optimal insertion site for a high l...

...V strains, 21 nucleotide insertion and 12 nucleotides deletions were identified in the GPCR genes of our isolates and other LSDVs. The amino acid sequences of GPCR genes of our isolates contained the unique signature of LSDV (A11, T12, T34, S99 and P199). Phylogenetic analyses showed that the GPCR genes of LSDVs identified from ticks were closest genetically to the previously detected LSDVs from infected ruminants, indicating a potential role of Ixodid ticks f...

... isolates illustrated no insertion, deletion and substitutions compared to A/DK/HK/Y280/97 lineage and human isolates (A/HK/1073/99 and A/HK/1074/99). Several amino acid substitutions at various regions of the NA protein were determined with unknown functions and consequences. These findings warrant future studies for analysis of whole genome sequencing of prevailing H9N2 viruses in Pakistan which may further contribute towards the better understanding of the ...

...ryotic genomes and their insertion in coding regions leads to altered gene expression. We examined the diversity of retroelements in four consecutive generations of different strains of Sordaria fimicola. The parental strains werecollected from two contrasting environments of Evolution Canyon i.e. harsh South facing slope and neutral North facing slope. Retroelements profiles were generated in order to detect retrotransposons. Strains from South ...

All six populations were characterized by low haplotype diversity (0.39–0.59) and low nucleotide diversity (0.00038–0.00073). The result of AMOVA and pairwise Fst values indicated weak or no genetic differentiation among different populations. Haplotype network and NJ phylogenetic trees revealed that there was no disti...

Ovulatory follicle diameter was measured at timed AI and progesterone profile (ng/mL) on d30 and d60 post AI. Pregnancy rate was analyzed by Chi-square procedure while ovulatory follicle diameter and Progesterone profile by one way ANOVA (α=0.05). Ovulatory follicle...

These evidences points towards the change of expression of those protein which are nearest to the region of gene regulation and enhancer region. After observing taxas several distinct clads of camel breeds it was found that Kharani breed showed the close relatio...

Azotobacter spp. with nematicidal activity could control root-knot nematode, Meloidogyne incognita. The development of such strains by genetic manipulation by transferring gene (s) required for saponins production is effective in increasing crop yield together with f...

Specific expression of the introduced antigen construct at the RNA level was detected by RT-PCR, using specific primers for the HSV-gD2 transcript. Expression of the HSV-2 gD antigen was assayed by ELISA on protein extracts isolated from same transfected plant tissue samples as for the RT-PCR assa...

Two unique substitutions, Gln39Arg and Lys47Glu have been noted in NA stalk domain of all isolates of this study which might be indirectly enhancing the virulence of virus. These findings demonstrated that new mutations are emerging in B2 sub-lineage and there is need for constant surveillance of evolving genome of H9N2 virus prevailing in the country to combat the...

Root neighbor-joining (NJ) tree revealed that the three HCV samples could be classified as genotype 4. Two of the three samples were closely related (98.2%) while the third clustered with isolate from Gabon (98.7%). The third isolate may be a new subtype but this will require an in-depth exploration on sequence variability in at least two coding regions....
