TLDR
Recent evidence suggests that Cyt synergize or overcome resistance to mosquitocidal-Cry proteins by functioning as a Cry-membrane bound receptor, and compares them to the mode of action of other bacterial PFT.About:

Insect pathogens as biological control agents: Back to the future.
Lawrence A. Lacey,David Grzywacz,David I. Shapiro-Ilan,Roger Frutos,M. Brownbridge,Mark S. Goettel +5 more
TL;DR: Current information on development, use and future directions of insect-specific viruses, bacteria, fungi and nematodes as components of integrated pest management strategies for control of arthropod pests of crops, forests, urban habitats, and insects of medical and veterinary importance is presented.

Bacillus thuringiensis: A story of a successful bioinsecticide
TL;DR: Recently, similar Cry-binding proteins have been identified in the three insect orders, as cadherin, aminopeptidase-N and alkaline phosphatase suggesting a conserved mode of action, suggesting a significant reduction in chemical insecticide use.

Bacillus thuringiensis insecticidal three‐domain Cry toxins: mode of action, insect resistance and consequences for crop protection
TL;DR: Activity of Cry1AMod toxins, which are able to form toxin oligomers in the absence of receptors, against different resistant populations, supports the hypothesis that toxin oligomerization is a limiting step in the Cry insecticidal activity.

Current knowledge and perspectives of Paenibacillus : a review
TL;DR: The genus Paenibacillus comprises bacterial species relevant to humans, animals, plants, and the environment as discussed by the authors, which can promote crop growth directly via biological nitrogen fixation, phosphate solubilization, production of the phytohormone indole-3-acetic acid (IAA), and release of siderophores that enable iron acquisition.

Bacillus thuringiensis toxins: an overview of their biocidal activity
TL;DR: An updated overview of the known active Bt toxins to date is provided and a less well characterized secretory protein with no amino acid similarity to Vips has shown insecticidal activity against coleopteran pests and is termed Sip (secreted insecticidal protein).

Lipid rafts and signal transduction
Kai Simons,Derek Toomre +1 more
TL;DR: It is now becoming clear that lipid micro-environments on the cell surface — known as lipid rafts — also take part in this process of signalling transduction, where protein–protein interactions result in the activation of signalling cascades.
