Abstract:

Lactate dehydrogenase (LDH) plays an important role in glycolysis and gluconeogenesis of protease. To explore the molecular characteristics and expression patterns of amLDH gene, in this study, the amLDH genes was cloned by RT-PCR, and its expression patterns of various caste, as well as at different developmental stages of Apis mellifera were analyzed. Moreover, its sequence characteristics were determined by bioinformatics methods. Sequence analysis indicated that the amLDH gene of A. mellifera contained an opening reading frame of 1 008 bp, encoding 335 amino acids, the sequence of amLDH was highly homologous to that of Apis cerana(96.4%). The amLDH had 13 phosphorylation sites and 2 functional domains of lactate dehydrogenase, which was a stable hydrophobic protein. The results of qRT-PCR indicated that the expression level of amLDH gene was of significant difference in various castes and at different developmental stages of A. mellifera(P<0.05). Expression in workers was the highest at 3 days of age in the egg stage. The highest expression in drones and queen was in 3 day-old egg and 4 day-old larvae, respectively. Expression of queen bees and drones was higher than that of worker bees from prepupa to red-eye pupa stage. The results suggested that the amLDH gene played an important role in the growth and glycolysis. This study provided a theoretical basis for exploring the function of amLDH gene in reproductive development in A. mellifera.
