Chitinase Genes

Albeit Metarhizium anisopliae is the best-characterized entomopathogenic fungus, the role of some hydrolytic enzymes during host cuticle penetration has not yet been established. Three chitinase genes (chit1, chi2, chi3) from Metarhizium have already been isolated. To characterize the chitinase coded by the chit1 gene, we expressed the active protein (CHIT42) in Escherichia coli using a T7-based promoter expression vector. The recombinant protein, CHIT42, is active against glycol chitin and synthetic N-acetylglucosamine (GlcNAc) dimer and tetramer substrates. These activities suggest that the recombinant CHIT42 acts as an endochitinase.Key words: Metarhizium anisopliae, chitinases, chit genes, recombinant protein, enthomopathogenic fungi.

Electrophoretic Data

The zymogram technique has been applied to three pathotypes of the entomopathogenic fungus Nomuraea rileyi. Isozyme profiles of isolates from Heliothis zea, Pseudoplusia includens, and Anticarsia gemmatalis were compared for 17 enzymes of known metabolic function. Electrophoretic data supported the taxonomic differences inferred for the three pathotypes based on host specificity. The isolate from A. gemmatalis was found consistently to be the most distinct.This study demonstrates that isozyme analysis may be used to distinguish closely related fungal isolates of N. rileyi.

Third Instar Larvae

The entomopathogenic fungus Nomuraea rileyi (Farlow) Samson produced a peptide active against Anticarsia gemmatalis 3rd instar larvae. To produce this peptide, N. rileyi was cultivated aerobically in Saboraud, maltose, yeast-extract broth at 26 ± 1ºC for 12 days, after which the medium was filtered and separated in a liquid/liquid extractor, concentrated and the peptide purified chromatographically. The crystals obtained were kept refrigerated until needed for LC50 analysis. The LC50 of this peptide against A. gemmatalis 3rd instar larvae was determined in triplicate experiments using solutions containing 1.0, 0.2, 0.1, 0.01, 0.001 and 0.0001 mg/ml of N. rileyi peptide. The results of these experiments were used to calculate a linear equation in which Y = 6,81176 + 1,01382 * LOGx , giving a LC50 value of 0.0163 mg/ml.
