4. CONCLUSION
In this study, the entire mitotranscriptomics of Apis melliferawere characterised for the first time. The following important findings
were also obtained in the present study: (i) mitochondrial genes had
polyadenyl sequences of 5 to 124 bases long, but the highest
representation for all genes was 5-9 base polyadenylated forms, (ii)
antisense transcripts were found as polyadenylated forms in transcript
pool, (iii) polyadenylation of annotated, monocistronic gene units was
the most common pattern, (iv) some of mitochondrial genes predominantly
appeared to form longer or shorter transcripts than annotated formal
gene length, (v) the overexpression of cox2 gene was potentially
due to the viral infection of selected sample, (vi) Apismitogenome had the coding capacity of 32 alternative ORFs, (vii) 18.70%
of studied transcripts contain at least one and at most seven additional
nucleotides before polyadenyls, especially the cytosine. Apart from,
comparisons from different tissues sequenced with different approaches
may provide further testing of mitochondrial gene expression profiles
due to the nature of transcriptomic analyzes.
