ATP-binding cassette transporter subfamily C members 2, 3 and cadherin protein are susceptibility-determining factors in Bombyx mori for multiple Bacillus thuringiensis Cry1 toxins.

Field-evolved resistance of insect pests to Bacillus thuringiensis (Bt) toxins (Cry toxins) is a threat to the efficacy of Bt-based bio-insecticides and transgenic crops. Recent reports have suggested that ATP-binding cassette transporter subfamily C2 (ABCC2) and cadherin-like receptor play important roles in conferring susceptibility to Cry1 toxins. However, the receptors involved in Bt susceptibility in each insect remain unclear. Read More

Cry toxins are insecticidal proteins used widely for pest control. They are lethal to a restricted range of insects via specific interactions with insect receptors such as the ABC transporter subfamily members C2 (ABCC2) and C3 (ABCC3). However, it is still unclear how these different receptors contribute to insect susceptibility to Cry1A toxins. Read More

Functional characterization of Bacillus thuringiensis Cry toxin receptors explains resistance in insects.

FEBS J 2016 12 29;283(24):4474-4490. Epub 2016 Nov 29.

Bacillus thuringiensis produces Cry toxins, which are used as insecticides in sprays and in transgenic crops. However, little is known about the function of Cry toxin receptors and the mechanisms that determine their binding specificity and activity. In this study, the cRNAs of Bombyx mori ABC transporter C2 (BmABCC2), the toxin-binding region of cadherin-like receptor (BtR175-TBR), or aminopeptidase N1 (BmAPN1) were injected into Xenopus oocytes, and the Cry1Aa-dependent cation-selective pore formation activities of these receptors were analyzed using a two-electrode voltage clamp.
