Gene, 2017
P-glycoprotein (P-gp) exists in animals, fungi and bacteria and likely evolved as a defense mechanism against harmful substances. Here a cDNA (4054bp) encoding a putative P-glycoprotein gene from Helicoverpa armigera was cloned and named HaPgp1. This putative HaPgp1 sequence encoded a protein of 1253 amino acids with a molecular mass of approximately ...

A nonalkaloid insecticide was isolated from the wild tomato Lycopersicon hirsutum f. glabratum and identified as 2-tridecanone, a compound 72 times more abundant in the wild tomato than in the cultivated tomato L. esculentum.

AbstractIn insect, the cytochrome P450 plays a pivotal role in detoxification to toxic allelochemicals.Helicoverpa armigeracan tolerate and survive in 2-tridecanone treatment owing to theCYP6B6responsive expression, which is controlled by some regulatory DNA sequences and transcription regulators.

The wild tomato accession Lycopersicon hirsutum f. glabratum ‘PI 134417’ is a promising source of resistance to arthropods in tomato. It is self compatible and intercrosses easily with the cultivated species Lycopersicon esculentum. It is resistant to several arthropods, including spider mites, and these resistances have been related to the presence of

AbstractThe expression level of cytochrome P450 genes in insects can be induced by plant allelochemicals, which is important for insects to adapt to host plants. Cytochrome P450CYP6B7has been reported to be involved in pyrethroid insecticide resistance inHelicoverpa armigera, and its transcription level was induced by some inducers.

Abstract In plants, one of the most sophisticated defensive strategies against herbivores is producing toxic metabolites for protecting themselves. 2-Tridecanone, which has been identified as a plant-derived and herbivore-induced defensive substance of plants, plays a role in retarding the development and decreasing the survival rate ...

AbstractThe allelochemic, 2‐tridecanone, which conditions resistance in the wild tomato Lycopersicon hirsutum f. glabratum to Manduca sexta and plays an important role in the resistance to Leptinotarsa decemlineate is shown to induce an enhanced level of tolerance to the carbamate insecticide carbaryl in a third important insect pest of tomato ...
