Identification and Expression Analysis of QM-Like Gene From Spodoptera litura After Challenge by the Entomopathogenic Fungus Nomuraea rileyi
A partial sequence of QM homologue was isolated from a Spodoptera litura fatbody suppression subtractive hybridization library. The full-length Spodoptera litura QM (SpLQM) cDNA of 838 bp contains a 5' untranslated region (UTR) of 112 bp, a 3' UTR of 66 bp, and an open reading frame of 660 nucleotides coding for a 219 amino acid peptide with a molecular weight of 25.5 kDa. Analysis of SpLQM seq...
متن کاملBiotransformation of sinesetin by the larvae of the common cutworm (Spodoptera litura).
Biotransformation of sinesetin (1) by larvae of Spodoptera litura was investigated. Compound 1 was converted to a new flavonoid, (+)-5,7,3',4'-tetramethoxyflavone-6-O-beta-D-glucoside (4), and two known flavones, 4'-hydroxy-5,6,7,3'-tetramethoxyflavone (2) and 6-hydroxy-5,7,3',4'-tetramethoxyflavone (3). These structures were established by IR, HR-EI-MS, HR-FAB-MS, 1D NMR, and 2D NMR spectral s...
متن کاملBiotransformation of (-)-(1R,4S)-Menthone and (+)-(1S,4R)-Menthone by the Common Cutworm Spodoptera litura Larvae.
Using biotransformation as a biocatalytic process has the advantage of being able to proceed under mild conditions and with high regio- and enantioselectivity. This study investigated the biotransformation of (-)-(1R,4S)-menthone (1) and (+)-(1S,4R)-menthone (2) by Spodoptera litura larvae. Compound 1 was converted to (-)-(1R,4S)-7-hydroxymenthone (1-1), (+)-(1R,3S,4S)-7-hydroxyneomenthol (1-2)...
متن کاملEffects of Pyriproxyfen on Female Reproduction in the Common Cutworm, Spodoptera litura (F.) (Lepidoptera: Noctuidae)
The common cutworm, Spodoptera litura, is a rapidly reproducing pest of numerous agricultural ecosystems worldwide. The use of pesticides remains the primary means for controlling S. litura, despite their negative ecological impact and potential threat to human health. The use of exogenous hormone analogs may represent an alternative to insecticides. Juvenile hormones (JHs) play an important ro...
متن کاملCharacterization of a germination-accelerating factor from the silkworm (Bombyx mori Linnaeus) of entomopathogenic fungus Nomuraea rileyi (Farlow) Samson.
The conidium of the entomopathogenic fungus, Nomuraea rileyi, has been found to germinate rapidly in the presence of a host insect-derived extract. This extract therefore appears to contain an important factor involved in host recognition by N. rileyi, although the substance (germination-accelerating factor, GAF) responsible for such unique germination behavior has yet to be identified. Our pre...
