Expression and distribution of cellulase, amylase and peptidase isoforms along the midgut of Morimus funereus L. (Coleoptera: Cerambycidae) larvae is dependent on nutrient substrate composition
The influence of diet composition - two substrates, wheat bran and sawdust - on isoform expression of digestive enzymes (cellulase, amylase and peptidase) in the midgut of Morimus funereus larvae was examined. Their impact on larval development was demonstrated by measuring the increase of larval weight during development and by analysis of digestive enzymes zymographic profiles, where the expression of cellulase isoforms from M. funereus larvae midgut has been examined for the first time in this study. Larvae reared on wheat bran had higher body weight between day 60 and day 100 than larvae reared on sawdust; however, both groups achieved similar body weight after day 110. Wheat bran as substrate induced different cellulase and amylase isoforms. Oak sawdust in substrate acted as inducer of peptidases. The highest cellulase activity and the greatest isoform variability were detected in the midgut extracts of larvae reared on wheat bran. From our results it can be assumed that M. funere...us endocellulase, amylase and peptidase are secreted in the anterior midgut, and their concentration gradually decreases towards the hindgut
