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.
