The Phosphofructokinase and Pyruvate Kinase Genes in Apis andreniformis and Apis cerana indica: Exon Intron Organisation and Evolution.

ABSTRACT: Genes related to carbohydrate metabolism have evolved rapidly in eusocial bees, including honey bees. However, the characterisation of carbohydrate metabolism genes has not been reported in Apis andreniformis or Apis cerana indica. This study aimed to characterise phosphofructokinase (PFK) and pyruvate kinase (PK) genes in these honey bee species and to analyse the evolution of the genus Apis using these genes. This study found the first data regarding A. andreniformis PFK and PK-like nucleotide sequences. A BLAST-n algorithm-based search showed that A. andreniformis and A. c. indica PFK and PK genes were homologous with those of Apis florea and Apis cerana cerana from Korea, respectively. Multiple alignments of PFKs from five Apis species showed many exon gains and losses, but only one among the PKs. Thus, the exon-intron organisation of the PK genes may be more conserved compare with that of the PFKs. Another evolutionary pattern indicated that more nucleotide substitutions occurred in Apis' PK than PFK genes. Deduced PFK amino acid sequences revealed a PFK consensus pattern of 19 amino acids, while the deduced PK amino acid sequences were predicted to have barrel and alpha/beta domains. Based on these two metabolism-related genes, The Neighbour-joining and Maximum likelihood phylogenetic trees are congruent and revealed that the A. andreniformis and A. florea group were in the basal position. Apis mellifera, A. cerana, and Apis dorsata formed a monophyletic clade, although the positions of A. mellifera and A. dorsata were different in the nucleotide- and amino acid-based phylogenetic trees.

Project description:We determined the complete genome sequence of a sacbrood virus (SBV) infecting Indian honey bee (Apis cerana indica) from Tamil Nadu, India named as AcSBV-IndTN1. The genome of AcSBV-IndTN1 comprised of 8740 nucleotides, encoding a single large ORF containing 2849 amino acids flanked by 5' and 3' untranslated regions. Results of phylogenetic tree analysis based on complete genomes of SBV isolates indicated that the virus isolates from India isolated from the Asiatic honey bee A. cerana (AcSBVs) formed a separate group along with six Vietnam isolates and three Chinese isolates. The AcSBV-IndTN1 isolate showed closer genetic relationship with other isolates from India. The second major group had both AcSBVs and AmSBVs (virus isolated from European honey bee, Apis mellifera SBV) of Korea, China and Vietnam. The third and a distantly related group had AmSBVs of Australia, UK, USA and Korea. The results obtained from phylogenetic analysis were further supported with evolutionary distance analysis. AcSBV-IndTN1 isolate open reading frame had 95-99% amino acid sequence similarity with other Indian isolates and 92-96% with AcSBVs and AmSBVs of other geographical locations. In addition, sequence difference count matrix ranged from 154 to 907 nt among all the SBV isolates. This suggests that the virus isolates have evolved significantly in different geographical locations but isolates on different hosts in a given location/country are closely related. The high similarity in the genome among the AcSBV and AmSBV isolates indicate possible cross-infections and recombination of SBV isolates in Asian continent where both the honey bee species are reared in close proximity. Gene flow between SBV population indicating that an infrequent gene flow occur between them. The pattern of molecular diversity in SBV population revealed that the occurrence of recent population expansion of SBV. To the best of our knowledge this is the first report of the complete nucleotide sequence of AcSBV from Tamil Nadu, India. This study provided an opportunity to establish the molecular evolution of SBV isolates and shall be useful in the development of diagnostics and effective disease control strategies.
