Sonoda S, Igaki C, Ashfaq M, Tsumuki H. Pyrethroid-resistant diamondback moth expresses alternatively spliced sodium channel transcripts with and without T929I mutation. Insect Biochem Mol Biol. 2006;36:904-10 pubmed
..These findings suggest that alternative splicing of the para-sodium channel gene might produce distinct channels with different sensitivities to pyrethroids, possibly in a tissue-specific manner. ..
Sonoda S, Igaki C, Tsumuki H. Alternatively spliced sodium channel transcripts expressed in field strains of the diamondback moth. Insect Biochem Mol Biol. 2008;38:883-90 pubmed publisher
..The frequencies of the M918I mutation in the field strains were 5.0-19.4%. Analyses of the genomic organization revealed that the chimeric sequences are encoded in the genome. ..
Sonoda S, Ashfaq M, Tsumuki H. Cloning and nucleotide sequencing of three heat shock protein genes (hsp90, hsc70, and hsp19.5) from the diamondback moth, Plutella xylostella (L.) and their expression in relation to developmental stage and temperature. Arch Insect Biochem Physiol. 2006;62:80-90 pubmed publisher
..These results suggest that in addition to a heat shock response, these HSP genes might be involved in other functions during the course of development in DBM...
Sonoda S. Molecular analysis of pyrethroid resistance conferred by target insensitivity and increased metabolic detoxification in Plutella xylostella. Pest Manag Sci. 2010;66:572-5 pubmed publisher
..Significant correlation between the target insensitivity and the increased metabolic detoxification in pyrethroid resistance of P. xylostella was observed in the laboratory but not in the field. ..
